OpenPhoenix

OpenPhoenix is a single-binary personal AI agent runtime written in Rust. It combines chat, background service, web UI, and CLI in one static binary that can be carried on a USB stick. The project states that it requires no Node, no Python, no runtime to install, and no telemetry. It works with 21 providers, speaks 3 API dialects, and can go live on 9 chat platforms in a single command. Configuration is stored in one TOML file with mode 600, and credentials come from the host environment, supported OAuth flows, or a sealed local store.

On first run, OpenPhoenix finds existing provider credentials or a local Ollama, writes the config, and picks a model that answers. It offers three memory modes: ghost forgets all, session forgets on restart, and recall keeps plain-text notes the user controls. Fallback chains allow switching model, provider, key, and endpoint mid-conversation, and multiple keys per provider rotate on rate limits. Colab mode lets two models plan, debate, divide the work, execute concurrently, and peer-review the result as equal seats.

Security features include a workspace file jail, command gate, secret scrubbing, SSRF blocking, and session quarantine, with fail-closed defaults. The runtime supports 9 chat channels: Telegram, WhatsApp, Discord, Slack, Signal, iMessage, IRC, Matrix, and Mattermost. It has 7 direct dependencies, no async runtime, and no runtime to install. An MCP client uses real JSON-RPC over stdio, and phoenix doctor provides a diagnostic check for config validity, permissions, service status, and security posture. OpenPhoenix is available for Linux, macOS, and Windows.
