A self-hosted, plugin-based agent harness. Four frontends, five backends, long-term memory.
Most harnesses are one-shot terminal wrappers. Talon runs as a long-lived process with persistent memory, hot-swappable MCP plugins, and frontends for wherever you need it — CLI, Telegram, Discord, Microsoft Teams, or your own.
Every backend implements the same capability interface — heartbeat, dream, and chat handlers don't know or care which one is running. Streaming, model fallback, and context-overflow recovery come standard.
In-process via the Claude Agent SDK. Hook-based turn termination.
Local HTTP server, SSE-streamed turns. Routes to many providers.
Local HTTP server. Same session shape as Kilo (upstream fork).
Per-turn subprocess on the Codex CLI's JSONL event stream.
Responses API, or any OpenAI-compatible endpoint.
Switch with one line: "backend": "claude" in ~/.talon/config.json.
Claude Agent SDK, Kilo, OpenCode, Codex, OpenAI Agents — one capability interface. Streaming, model fallback, context-overflow recovery.
18+ MCP plugins. Built-ins ship in the box; drop-in path plugins follow a uniform shape. Hot-reload at runtime.
Mempalace integration. ChromaDB vector store + SQLite knowledge graph. Semantic recall across sessions.
Same brain, different mouths. Telegram, Discord, Teams, terminal — or write your own.
Background modes for memory consolidation and proactive maintenance. Reflects on its own logs while you sleep.
Your VPS, your data, your backend choice. 3,300+ tests. No vendor lock-in — swap the backend, keep the agent.
A model-free identity substrate that persists across sessions. Collects signal taps — reactions, corrections, directives — and builds a self-organizing representation independent of any backend.
Internal plugins live in the talon repo. External path plugins live in the
talon-agent
org and follow a uniform shape: a package.json + an src/index.ts.
Stars are the easiest public signal that this project is worth trying. They help developers find Talon before they settle for another thin chat wrapper.
Talon gives you Telegram, Discord, Teams, terminal, and desktop/mobile frontends over one agent core, with MCP plugins, cron, triggers, goals, heartbeat, and dream mode.
Install, run the setup wizard, start. Bring your own backend — Claude Code login, Codex, or an API key.
