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.

Prices and plans

TierPricePeriodWhat you get
Harness (MIT, self-hosted)freefreeMIT license, fully open source; self-host with one command (`npx @truefoundry/trueforge@latest`)
Sandbox execution via Daytona, durable sessions in SQLite or Postgres, human approvals, subagents, and a Git-backed skills registry

Prices per vendor, excl. taxes/VAT where applicable.

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.

How we compare

We compare free access, paid entry, plan limits, features and the listed official sources. Unsourced figures stay marked as not published.

Only confirmed entries appear in the catalog. Prices, plans and limits come from listed official vendor pages. Missing figures stay marked as not published. Search results are ordered by Task match by default; category and task lists are alphabetical. Both can be switched to Free access first; neither is a quality ranking. The vendor page always wins.
