About

TrueForge runs the agent execution loop, including model calls, MCP tools, skills, sandboxed code execution, approvals, context management and session state. It exposes that loop as a chat UI, an HTTP API with a TypeScript SDK, and an embeddable UI SDK. It runs in local mode on SQLite or in hosted mode on Postgres and Redis, deployed with Docker Compose, Helm or Railway.

Use cases: agent-orchestration
