Hermes Agent: OpenClaw Alternative With Memory and Skills

16 min read

Most AI assistants are useful until you close the conversation.

Start a new session and you may find yourself explaining the same project structure, deployment process, preferred tools, coding conventions, or research workflow all over again. That gets frustrating quickly when you want AI to do more than answer isolated questions.

Hermes Agent takes a different approach. It is an open-source AI agent from Nous Research that combines persistent memory, reusable skills, terminal tools, scheduled jobs, subagents, messaging, and multiple execution backends inside a shared agent runtime. That makes Hermes particularly interesting for developers who want an AI agent that can keep context, reuse procedures, and perform real work across sessions.

Hermes is also increasingly compared with OpenClaw. The two projects now overlap in memory, skills, automation, messaging, tool use, and isolated execution, but they organize those capabilities differently.

The simplest distinction is this:

Hermes is built around a shared AI agent runtime. OpenClaw is built around a long-running Gateway.

That architectural difference affects how each platform handles terminals, automation, messaging, clients, memory, and remote agents.

Hermes Vs OpenClaw: Key Differences

Before looking deeper into Hermes, here is the practical difference between the two platforms.

Area Hermes Agent OpenClaw
Core design Shared AIAgent runtime used by the CLI, gateway, automation, editors, batch jobs, and APIs Long-running Gateway acts as the control plane for agents, channels, clients, and devices
Persistent memory Bounded MEMORY.md and USER.md, plus SQLite FTS5 session search and optional external memory providers USER.md, MEMORY.md, dated memory notes, DREAMS.md, searchable memory, and background consolidation
Skill learning Agent-managed skills, /learn, background review, and progressive skill loading Skill Workshop proposals, operator review, scheduled collection review, ClawHub, and external skill sources
Execution Local, Docker, SSH, Singularity, Modal, Daytona, and Vercel Sandbox Host execution plus Docker, Podman, SSH, OpenShell, Crabbox, and other configurable sandboxes
Primary orientation Runtime-centered developer, automation, terminal, and technical workflows Gateway-centered messaging, devices, web control, agents, and remote clients
Migration hermes claw migrate imports selected OpenClaw state Hermes memory files can be imported through OpenClaw’s memory workflow

These similarities are important because older comparisons can now be misleading. Both projects evolved substantially during 2026, adding richer memory, skills, automation, sandboxing, messaging, and multi-agent capabilities.

What Is Hermes Agent?

Hermes Agent is an open-source AI agent framework maintained by Nous Research. It lets an AI model remember useful information, call tools, execute commands, reuse learned procedures, delegate work, and run scheduled tasks without tying the entire system to one model provider.

Think of Hermes as the runtime around the language model.

The model performs reasoning and generates tool calls, but Hermes manages the environment surrounding it: context, tools, memory, skills, execution, sessions, retries, automation, and integrations.

Hermes can work with Nous Portal, OpenRouter, OpenAI-compatible services, self-hosted endpoints, and other supported providers. The model can therefore change while the surrounding agent workflow remains in Hermes.

The same core runtime powers several entry points, including:

  • Command-line sessions
  • Messaging
  • Scheduled jobs
  • Batch tasks
  • Agent Client Protocol integrations
  • API access
  • Editor integrations
  • Python workflows

That shared runtime matters more than it may initially appear. A workflow you build around Hermes does not have to exist only inside a terminal chat. The same agent behavior can participate in automation, APIs, messaging, or scheduled jobs.

How Hermes Agent Works

Suppose you ask Hermes:

Check my application repository, run the tests in Docker, inspect any failures, compare them with previous incidents, and send me a summary.

That request moves through several layers rather than going directly to an LLM.

Hermes first builds the context the model needs. It can include the active conversation, relevant project instructions, memories, user information, and matching skills.

The model then receives access to the tools allowed for that session. If it decides to run a command, search a session, inspect a file, use a browser, or delegate work to a subagent, Hermes executes the tool call and returns the result.

The model evaluates that result and continues the loop until it can produce a final answer.

Hermes also manages operational details such as retries, context compression, callbacks, fallback behavior, and session persistence.

Hermes Agent Architecture

The architecture becomes easier to understand when you follow one request from input to completion.

Hermes separates prompt construction, model access, tools, execution, and persistent state rather than treating everything as one enormous chat prompt.

Its prompt builder uses different categories of information.

  • Stable content includes information that changes rarely, such as agent identity and general tool instructions.
  • Contextual content can include project files and relevant skills.
  • Volatile content includes memory, user profile information, timestamps, and other session-specific context.

Hermes offers more than 70 registered tools across roughly 28 toolsets.

The advantage of this architecture is straightforward: Hermes does not need to stuff every piece of historical information and every procedure into every prompt.

This becomes especially important when you use the agent repeatedly.

Hermes Agent Memory And Persistent Context

One of the first problems with long-running AI workflows is repetition.

You probably do not want to tell an agent your preferred package manager, project conventions, repository layout, deployment target, or workflow rules every time you start a new conversation.

Hermes solves this by separating compact long-term memory from searchable conversation history.

MEMORY.md and USER.md contain information the agent is likely to need frequently.

Historical sessions remain searchable through SQLite Full-Text Search 5, or FTS5. That means older details can be retrieved when needed without permanently occupying the model’s context window.

Hermes deliberately keeps the primary memory small. The default budgets described in the source article are approximately:

  • MEMORY.md: 2,200 characters
  • USER.md: 1,375 characters

Instead of treating memory as an unlimited notebook, Hermes keeps frequently useful facts compact while moving older detail into searchable history.

Hermes Memory Vs Skills

Memory and skills may look similar at first, but they solve two different problems.

  • Memory answers: “What should the agent remember?”
  • Skills answer: “How should the agent perform this task?”
Area Memory Skills
Purpose Store durable facts and preferences Store reusable procedures and task knowledge
Typical content Preferred tools, user preferences, project facts Deployment processes, research workflows, review checklists
Loading Injected as bounded session memory Skill catalog is loaded first; complete SKILL.md loads when relevant
Example “Use uv for Python package management” “Deploy a FastAPI service using this production checklist”

This distinction makes Hermes more useful for recurring technical workflows.

A memory might tell Hermes that your production applications run behind Nginx.

A skill could describe the complete deployment procedure: build the container, validate environment variables, deploy the service, test the health endpoint, check logs, verify Nginx, and perform rollback if validation fails.

There is an important detail developers should know about Hermes memory.

When Hermes writes information to MEMORY.md or USER.md, the file itself changes immediately. , the prompt snapshot already loaded into the active session is not automatically rebuilt.

The updated memory becomes part of the context when a new session starts.

For older information, Hermes uses a different mechanism.

Historical conversations are stored in SQLite and searchable with FTS5. Instead of asking another LLM to summarize those conversations, session search can return the stored messages themselves.

This creates a useful three-layer context model:

Current conversation → bounded long-term memory → historical session search

The current conversation handles immediate work. Memory handles durable facts. Session search handles older details that do not deserve permanent space in every prompt.

Skills: Where Hermes Becomes More Than A Chatbot

Memory helps Hermes remember facts.

Skills help it stop reinventing procedures.

Suppose you regularly ask an AI agent to audit a Linux server. You might repeatedly explain that it should check disk usage, failed systemd services, listening ports, package updates, authentication failures, Docker containers, firewall status, and recent logs.

With a skill, that procedure can become reusable.

Hermes first loads a lightweight catalog describing available skills. When a task matches one of them, it loads the complete SKILL.md containing the required procedure.

This progressive disclosure keeps large instructions out of the permanent context while still making specialized knowledge available when required.

User skills are stored under:

~/.hermes/skills/

Hermes also provides a /learn workflow that can turn documents, web material, previous workflows, or user notes into reusable knowledge. Agent-created changes remain subject to configured write-approval controls.

Tool Use And Autonomous Workflows

An agent becomes significantly more useful when it can act on information rather than merely describe what you should do.

Hermes supports tool execution across several environments, including:

  • Local execution
  • Docker
  • SSH
  • Singularity
  • Modal
  • Daytona
  • Vercel Sandbox

Other toolsets cover areas such as browsers, files, research, memory, messaging, and subagents.

Hermes can also extend its tool registry through Model Context Protocol (MCP) servers.

Scheduled jobs add another important capability.

Instead of leaving a chat session running indefinitely, a scheduled job can launch a fresh agent run at the required time.

That makes Hermes suitable for recurring operational tasks such as health checks, repository maintenance, reports, and infrastructure reviews.

Example: Daily Repository Health Check

Consider a development team that wants an automated repository check every morning.

A Hermes skill could contain:

  • Repository locations
  • Test commands
  • Docker instructions
  • Log locations
  • Failure-handling rules
  • Reporting requirements

A scheduled job starts a fresh Hermes run.

The agent loads the relevant skill, executes tests in Docker, examines failures, searches earlier sessions for similar incidents, and sends the resulting report through an approved messaging channel.

This is where memory, skills, tools, session search, and scheduling stop looking like unrelated features and start working as one agent system.

Deploy Hermes As A One-Click Application On Atlantic.Net

If you would rather keep Hermes running on persistent cloud infrastructure than maintain it on a workstation, Atlantic.Net offers Hermes Agent as a One-Click Application on its On-Demand Cloud platform.

You select the Hermes application, choose a Cloud Server plan and region, launch the instance, and then connect your preferred supported model provider.

The prebuilt server image handles the base deployment. Model credentials, schedules, tools, application updates, monitoring, security, and backups remain under your administration.

Hermes Agent Pricing And Deployment Costs

Hermes Agent itself does not require a software license fee because the runtime is open source.

That does not mean operating an autonomous agent is free.

Your actual cost usually comes from four areas:

Model inference + compute + backups + external integrations

The following examples reflect the pricing included in the source article and checked there on September 25, 2026.

Cost area Current example What you pay for
Hermes Agent runtime $0 software license Open-source agent runtime and local state
Nous Portal Free $0/month Free models with standard rate limits
Nous Portal Plus $20/month $22 monthly credits, 200+ models, hosted tool usage
Nous Portal Super $100/month $110 monthly credits, 200+ models, hosted tool usage
Nous Portal Ultra $200/month $220 monthly credits, 200+ models, hosted tool usage
Cloud server example Atlantic.Net from $10/month on-demand Persistent server compute; model charges remain separate
Optional daily backups 20% of server price Backup service on referenced cloud plans
Other model providers Varies Token-based inference, subscription access, or self-hosted compute

For a small deployment, the host may be inexpensive.

Inference can become the larger expense when autonomous tasks involve long context windows, repeated model-tool loops, subagents, or several model calls per job.

Hermes Agent Vs OpenClaw

At this point, comparing Hermes and OpenClaw with a simple feature checklist is not particularly useful.

Both now provide many of the capabilities people expect from autonomous agent platforms.

The more useful question is:

How do you want the agent system itself to be organized?

Hermes places its shared AIAgent core at the center.

OpenClaw places its persistent Gateway at the center.

Memory

Hermes favors compact memory backed by direct historical retrieval.

It keeps small MEMORY.md and USER.md files for frequently needed information and uses FTS5 when older session content is required.

OpenClaw uses a broader workspace-oriented memory model involving files such as USER.md, MEMORY.md, dated notes, optional DREAMS.md, searchable memory, and background consolidation.

Skills

Hermes allows the agent to create or modify skills through its learning and skill-management workflows, depending on configured approval controls.

OpenClaw uses a Skill Workshop model with proposed skills, operator review, scheduled collection review, ClawHub, and external skill sources.

Runtime Vs Gateway

The biggest architectural difference remains the center of gravity.

Hermes exposes one AIAgent runtime through terminal sessions, automation, messaging, editors, APIs, and other entry points.

OpenClaw’s long-running Gateway coordinates messaging surfaces, web clients, devices, remote nodes, agents, and routing.

For developers heavily focused on repositories, terminals, servers, and scheduled automation, Hermes’ runtime-oriented approach may map naturally to the work.

For environments centered on persistent messaging, connected devices, remote clients, and gateway-managed agent routing, OpenClaw provides a different operating model.

Security, Privacy, And Deployment

Giving an AI agent a terminal is fundamentally different from giving a chatbot a text box.

A Hermes deployment may interact with files, shells, browsers, credentials, remote servers, APIs, and external services. The security model should therefore be treated like any other automation system with privileged access.

Hermes provides controls including:

  • Authorization checks
  • Dangerous-command approval
  • File-write restrictions
  • Container isolation
  • MCP credential filtering
  • Context-file scanning
  • Session separation
  • Input sanitization
  • Pairing
  • Messaging allowlists

For higher-risk workloads, limit the available toolset and credential scope and move execution into Docker or another isolated backend where appropriate.

Self-hosting also does not automatically make every workflow private.

If Hermes sends prompts to a hosted model, browser service, search API, messaging service, or external MCP server, that service receives the information required to process its part of the task.

The same principle applies to OpenClaw.

Best Use Cases For Hermes Agent

Hermes becomes most when the task is not a one-off conversation.

It fits workflows where the agent needs to remember context, follow repeatable procedures, use technical tools, and return to the job later.

Developer And DevOps Automation

Hermes can support repository maintenance, deployment scripts, infrastructure checks, testing, troubleshooting, log analysis, and recurring operational tasks.

Docker and SSH execution are especially useful when the work should run outside the developer’s local environment.

Research With Long-Term Context

Research projects often stretch across days or weeks.

Bounded memory can preserve important project context while FTS5 search retrieves earlier decisions, sources, experiments, and constraints when required.

Reusable Technical Procedures

Skills work well for repeatable processes such as:

  • Release management
  • Security reviews
  • Server provisioning
  • Incident checks
  • Article research
  • Documentation workflows

Instead of rebuilding the procedure in every prompt, Hermes can load the relevant skill only when the task requires it.

Always-On Agent On A VPS

Running Hermes on a VPS allows scheduled jobs, messaging, and persistent state to continue without leaving your workstation powered on.

The deployment should still include ordinary server practices such as backups, resource limits, restricted credentials, monitoring, and isolated execution.

Hermes Agent Limitations And Trade-Offs

Hermes’ memory model is intentionally bounded.

That helps prevent permanent context from growing uncontrollably, but it also means durable information needs to be curated. Older information may require session search or an external memory provider instead of appearing automatically in every prompt.

Agent quality also depends heavily on the underlying model.

If a model performs poorly at structured tool calling or instruction following, that weakness can affect memory writes, skill creation, error recovery, and multi-step execution.

External skills and MCP servers introduce another consideration: supply-chain risk.

The more external components an autonomous agent can execute or trust, the more carefully those components should be reviewed.

There are operational responsibilities as well.

Always-on agents still need:

  • Updates
  • Backups
  • Monitoring
  • Logging
  • Credential rotation
  • Resource limits
  • Recovery testing

Hermes automates tasks. It does not eliminate normal infrastructure operations.

Who Should Use Hermes Agent?

Hermes is particularly relevant for developers, DevOps engineers, AI experimenters, and technical teams that want one agent runtime to work across terminal sessions, scheduled jobs, editors, APIs, messaging, and other technical entry points.

Its combination of persistent memory, searchable sessions, reusable skills, terminal tools, subagents, scheduling, and flexible model providers makes it useful for workflows that continue beyond a single chat.

OpenClaw approaches the same broader agent problem from a different direction, placing a persistent Gateway at the center of messaging channels, devices, remote clients, web control, and agent routing.

Neither difference can be captured well by asking which project has “memory” or “skills.” Both do.

The more useful comparison is how you want the agent to operate inside your environment.

Hermes Agent Or OpenClaw: What Is The Practical Difference?

Hermes is organized around a shared runtime that works across technical workflows such as terminal execution, automation, APIs, editors, and messaging.

OpenClaw is organized around a long-running Gateway connecting agents with messaging channels, clients, devices, web control, and remote nodes.

Both now support overlapping capabilities, including memory, skills, automation, external tools, messaging, and isolated execution. The meaningful difference is therefore less about individual features and more about which architecture better matches the way you intend to run the agent system.

Frequently Asked Questions

Is Hermes Agent An OpenClaw Replacement?

Hermes overlaps with many OpenClaw use cases, but the two systems use different architectural models. Hermes also provides hermes claw migrate for moving selected OpenClaw state into a Hermes-centered workflow.

Does Hermes Agent Remember Information Across Sessions?

Yes. Hermes uses MEMORY.md and USER.md for compact long-term information, while SQLite FTS5 allows the agent to retrieve older session content when needed.

Does Hermes Agent Create Its Own Skills?

Yes. Hermes provides skill-management tools, /learn workflows, and background review mechanisms that can turn useful procedures into reusable skills, subject to configured write controls.

Does OpenClaw Also Learn Skills?

Yes. Current OpenClaw releases include Skill Workshop workflows where agents can propose reusable skills for review, along with scheduled collection processes for scoped updates.

Does Hermes Agent Support Local Models?

Yes. Hermes can use compatible self-hosted endpoints such as Ollama and vLLM alongside hosted model providers.

The model still needs reliable instruction following and tool-calling capabilities because agent workflows depend on structured actions rather than text generation alone.

Is Hermes Agent Fully Private?

Not necessarily.

Local runtime state can remain on infrastructure you control, but hosted model providers and external integrations receive the information necessary to process their requests. Using a self-hosted model endpoint can reduce the amount of inference data sent to third parties.

Is Hermes Agent Safe To Run With Terminal Access?

Hermes provides approval, authorization, write safety, scanning, credential filtering and isolation controls.

For untrusted or higher-risk terminal workloads, use restricted credentials, a dedicated account, and an isolated execution backend instead of giving the agent unnecessary host access.
