# Hermes vs OpenClaw — Which Platform Is Right for You?

Hermes and OpenClaw solve different problems. OpenClaw is a conversational agent: you talk to it, it does things, the conversation ends. Hermes is an autonomous agent: you give it a goal with a deadline, it plans and executes across hours or days, and checks in when it needs you. The question isn't which is better — it's which fits the task. Most serious users end up running both.

## The Core Difference

The architectural difference that drives everything else: **OpenClaw is session-scoped, Hermes is goal-scoped.**

- **OpenClaw** — you open a conversation, give instructions, get responses. The context lives for the duration of the session. When you close it, it's done. Memory carries over via MEMORY.md files, but execution doesn't.
- **Hermes** — you submit a goal. Hermes plans it, executes it across multiple scheduled steps, and completes it — with or without you present. Memory is a database that grows across months, not a file you manually maintain.

## Full Comparison

| Dimension | OpenClaw | Hermes |
| --- | --- | --- |
| **Execution model** | Conversational — you drive each turn | Autonomous — runs to completion without prompting |
| **Memory model** | Session context + MEMORY.md file (manual) | SQLite/PostgreSQL database with 3 memory types; auto-grows |
| **Memory duration** | As long as you maintain MEMORY.md | Indefinite — database persists until you delete it |
| **Task duration** | One session (minutes to hours) | Hours to weeks; survives restarts |
| **Scheduling** | Via HEARTBEAT.md cron (simple) | First-class feature — natural language scheduling, recurring tasks, deadlines |
| **Tool ecosystem** | 53 official skills + 13,700+ community | MCP tools (100+ servers, growing open standard) |
| **Tool compatibility** | OpenClaw skills only | Any MCP-compatible server |
| **Self-improvement** | No — same behavior across sessions | Yes — reflection cycle writes procedural memory that influences future tasks |
| **Setup time** | Under 10 minutes | ~20 minutes |
| **Channels** | WhatsApp, Telegram, Discord, email, iMessage | Telegram and Discord (full gateway); email for alerts |
| **Conversational quality** | Excellent — designed for back-and-forth | Good but not optimised — Hermes is an executor, not a conversational partner |
| **Skill/tool writing** | SKILL.md format — agent writes them | MCP server format — requires Node.js or Python code |
| **Cost model** | Pay per conversation turn | Pay per task step (potentially far fewer calls for equivalent work) |
| **Typical monthly cost** | $3–20 depending on usage | $5–30 depending on task complexity and frequency |
| **Best model choice** | Haiku for most tasks, Sonnet for complex | Sonnet default, Opus for heavy reasoning, auto-escalation |
| **License** | MIT (fully free) | MIT (fully free) |
| **Maturity** | Stable, large community | v0.15.2 — stable, MCP native support included, no longer experimental |

## When to Choose OpenClaw

- You want to **talk to your agent** — back and forth, real time
- Tasks complete in a single session (under a few hours)
- You want WhatsApp or iMessage as a channel (Hermes supports Telegram and Discord but not WhatsApp/iMessage)
- You want the richest skill ecosystem — 53 official + community options
- You're new to self-hosted agents — OpenClaw is simpler to start with
- You need group chat support for a team setting

## When to Choose Hermes

- Tasks that take **more than a few hours** and don't need you at every step
- Research projects spanning days or weeks
- You want the agent to **improve itself** — better approaches on similar tasks over time
- You need a proper **memory database**, not a markdown file you maintain manually
- You want to schedule goals, not just cron jobs — "finish this by Friday" rather than "run this command at 9am"
- You're using MCP tools that work across clients (Claude Desktop, Cursor, Hermes all share the same servers)

## Running Both Together (Recommended Setup)

The most powerful setup is to run both simultaneously and route tasks to whichever is better suited:

| Task type | Use |
| --- | --- |
| Quick questions, conversational help, real-time drafting | OpenClaw |
| Morning brief, email triage, GitHub notifications check | OpenClaw (via HEARTBEAT.md) |
| Research projects spanning multiple days | Hermes |
| Complex analysis that requires reading many sources | Hermes |
| Recurring monitoring with adaptive responses | Hermes |
| Writing long documents that need consistent context | Hermes |
| WhatsApp or iMessage interaction | OpenClaw (Hermes doesn't support WhatsApp/iMessage) |

They run on different ports and don't interfere:

```
# OpenClaw on 18789 — for conversational use
openclaw gateway   # background via systemd

# Hermes on 18791 — for long-running tasks
hermes start       # daemon mode via systemd

# Both share a Telegram bot — route by prefix:
# "hermes: research AI memory for the next week" → goes to Hermes
# "what's the weather today?" → goes to OpenClaw
```

Configure routing in your Telegram bot's SOUL.md or PERSONA.md: tell OpenClaw that messages starting with "hermes:" should be passed to the Hermes API endpoint, and everything else handled normally.

## Sharing Memory Between Hermes and OpenClaw

The two systems use different memory formats — Hermes has a database, OpenClaw has MEMORY.md. But you can bridge them:

- **Hermes → OpenClaw:** Add a Hermes recurring task that exports a summary of key facts from Hermes's semantic memory to OpenClaw's MEMORY.md weekly. Hermes can write files to any path you grant.
- **OpenClaw → Hermes:** Use the Hermes CLI to manually add facts from OpenClaw sessions: `hermes memory fact add "..."`
- **Shared workspace files:** Point both systems at the same workspace directory (set `~/.hermes/workspace` to the same path as `~/.openclaw/workspace`) — SOUL.md/PERSONA.md, MEMORY.md, and notes files are readable by both.

## Cost Comparison in Practice

A common concern: "Hermes runs longer tasks — does it cost more?" Not necessarily. The comparison that matters is *cost per outcome*, not cost per API call:

| Task | OpenClaw approach | Hermes approach | Cost comparison |
| --- | --- | --- | --- |
| Research 20 sources and write a report | You guide it through 40+ conversation turns across several sessions | Submit once, Hermes executes 8–12 steps autonomously | Hermes: 2–3× cheaper (fewer context tokens re-sent) |
| Morning brief | Heartbeat cron, runs in <60 seconds | Scheduled task, similar execution | Roughly equal |
| Quick question | One turn, done | Overhead of task planning + execution | OpenClaw: 5–10× cheaper for simple Q&A |
| Monitor and react to changes over a week | Multiple manual sessions as things change | One task with check-ins; Hermes adapts autonomously | Hermes: significantly cheaper and more thorough |
