Hermes Agent vs OpenFang
These two do compete: both are free, open-source agents you run yourself that work on a schedule and answer through chat apps. Hermes Agent is built around one assistant that learns you over time (memory, session search, skills it writes itself). OpenFang is a Rust "agent operating system" that ships seven prebuilt autonomous agents, called Hands, for jobs like lead generation, research and posting to X. The bigger practical difference today is activity: Hermes shipped a release on 15 October 2026, while OpenFang's last release was v0.6.9 on 12 May and its repo hasn't had a push since early July.
One learning assistant or a set of workers
Hermes keeps agent-curated memory, recalls past sessions with full-text search, and turns hard tasks into skills it reuses and refines. It has a built-in cron that can deliver results to any chat platform, and it can spawn subagents for parallel work.
OpenFang's Hands are Clip (video shorts), Lead (prospect discovery and scoring), Collector (OSINT monitoring), Predictor (forecasting), Researcher (cited reports), Twitter (account management) and Browser (web automation that asks before purchases). You turn one on and it runs on its schedule.
Install, channels and models
OpenFang is a single binary of about 32 MB, installed with a curl script on macOS and Linux or PowerShell on Windows, plus a Tauri desktop app. It lists 40 channel adapters and 27 model providers through Anthropic, Gemini and OpenAI-compatible drivers. It's dual-licensed MIT and Apache 2.0.
Hermes (MIT) installs with a script on Linux, macOS or WSL2, PowerShell on native Windows, or Termux on Android. Its gateway covers Telegram, Discord, Slack, WhatsApp and Signal, and it works with Nous Portal, OpenRouter, OpenAI or your own endpoint. Commands can run locally, in Docker, over SSH, or in Modal, Daytona, Singularity or Vercel Sandbox.
How settled each one is
OpenFang calls itself feature complete but pre-1.0, warns of breaking changes between minor versions, and tells production users to pin a commit. Its README aimed for a stable 1.0 around mid-2026, which hasn't arrived, and openfang.sh still shows v0.1.0. Hermes is moving fast in the other direction, with frequent releases, so expect change there too, just not silence.
Hermes Agent: Pick Hermes Agent if you want one self-hosted assistant that builds up memory and skills and is still actively released.
OpenFang: Pick OpenFang if you want prebuilt scheduled agents for leads, monitoring or social posting in one small binary, and can live with a pre-1.0 project that has gone quiet.

Field notes
All field notes →- Goose and Hermes: the model changed our task-test results
Goose completed five of nine attempts with our small local model and Hermes completed none. With the recorded hosted model, both completed all nine. The model and context…
- OpenCode with a 3B model: check the files, not just the exit status
OpenCode created the requested file in all three small-model attempts, but passed neither of the other tasks. Its hosted-model rerun passed all nine attempts.

Hermes Agent
Hermes Agent from Nous Research keeps memory across sessions, saves reusable skills and can be reached through messaging apps. We ran it on three tasks with a local 3B model and with Claude Opus 5.5.
