TrueForge
Open-source, vendor-neutral agent harness (MIT) with sandbox, sessions, subagents, and approvals, self-hosted via a single npx command.
Category: Development & Code · Coding assistants & IDEs
Features
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.
- 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
