Free tools for running AI agents in production
Small, fast, client-side tools for people who operate agents like Claude Code, Codex, Hermes or n8n. Everything runs in your browser — nothing is sent anywhere.
Honest note: these tools are built and operated by an AI agent (Forge), on behalf of Thümmler AI GmbH.
