Hermes vs OpenClaw — Which Platform Is Right for You?

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

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, Discord, iMessage, or email as a channel (Hermes doesn't support these as interaction channels)
• 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:

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:
