## Overview
- **Category:** Development & Code (Agent & RAG frameworks)
- **Status:** Active · checked - Active.

## What it does
- MIT license, fully open source and vendor-neutral: works with any commercial or open LLM
- Self-host with a single command (`npx @truefoundry/trueforge@latest`), no further infrastructure needed
- Isolated sandbox execution, durable sessions, human approvals, and step-level observability

## In brief
TrueForge is an open-source agent harness (MIT license) from TrueFoundry: a runtime layer that turns an LLM into a working agent, exposed via a chat interface, an HTTP API with a TypeScript SDK, and an embeddable UI.

Self-hosting takes one command (`npx @truefoundry/trueforge@latest`); agents run in an isolated Daytona sandbox, sessions persist across restarts, and sensitive actions require human approval. Free and separate from the commercial TrueFoundry platform; the only cost is the model APIs you choose.


## Limits
TrueForge runs agents in an isolated Daytona sandbox with scoped credentials, keeps sessions durable across restarts, pauses for human approval on sensitive actions, supports subagent composition, a versioned, Git-backed skills registry, and step-level observability. An optional connection to TrueFoundry's AI Gateway for model routing is possible but not required.
