What makes Hermes different

An agent that grows with you

Real workflows

What people actually run Hermes for

Concrete jobs, not vague “automation.” Pick the path closest to your work.

The honest version

Self-hosting is powerful. It’s also work.

Running your own agent means a VPS, API keys, model routing, security, and upkeep. That’s real control — and real overhead. FlyHermes removes the overhead so you can start today.

Easiest way to start

FlyHermes Cloud

  • • Live in under 60 seconds — no server to provision
  • • Managed infrastructure, models, and updates
  • • Predictable pricing — no surprise API bills
  • • Best for founders, operators, and lean teams
Maximum control

Self-host Hermes

  • • MIT licensed — audit and modify everything
  • • Bring your own models and API keys (~$5/mo VPS)
  • • Your data stays on your infrastructure
  • • Best for developers, labs, and infra-heavy teams

What early users are saying

Hermes is a lot more steady, doesn't get lost at every update, and feels like it remembers things

The memory system means it actually gets better at our specific workflows over time
Nous Research Discord community
We deployed it on a $10 VPS and it handles our entire Telegram workflow
Developer testimonial
The memory system means it actually gets better at our specific workflows — it learns your research methodology and applies it consistently
Nous Research Discord community
Being able to run a research pipeline that browses, analyzes, and writes in one flow is genuinely new — I haven't found this anywhere else
Developer / researcher on Reddit
Hermes remembers what you were working on even after weeks away — that context gap is usually where research momentum dies

FAQ

Common questions

How does Hermes remember my codebase between sessions?+

Hermes uses a three-layer memory system. MEMORY.md and USER.md are injected as a frozen snapshot into every session's system prompt — these hold your stack, conventions, and preferences. Episodic memory (ChromaDB) stores what was tried and what worked. All conversations are also stored in SQLite with FTS5 search for unlimited recall.

Is this actually affordable for a solo business?+

Hermes itself is free (MIT license). Your costs are: a VPS (~$5/month for a small instance), your LLM API key (usage-based, often $5-20/month for light customer support use), and your time for initial setup. There's no per-seat, per-user, or per-message platform fee.

How does the research memory differ from just saving notes in Notion?+

Notion saves what you write. Hermes remembers what you read and what you concluded — automatically, without manual note-taking. It can also reason across your accumulated reading history, surfacing connections and contradictions between papers you read months apart.

What platforms can my customers reach Hermes on?+

Any of them: Telegram, Discord, Slack, WhatsApp, Signal, email, or a web widget. All from a single gateway process. You configure which platform handles customer-facing conversations versus internal team communication.

Does Hermes work with my existing IDE and workflow?+

Hermes runs as a server process and connects via Telegram, Discord, Slack, CLI, or any messaging platform. It doesn't require a specific IDE. The agent works alongside your existing tools — you describe what you want, Hermes uses its tools to accomplish it, and reports back.

Can Hermes track citations and build a bibliography?+

Hermes stores citation information in persistent memory when it reads papers. You can query your accumulated citation library at any time. For formal bibliography generation, it can output in BibTeX, APA, or any format you specify.
