TrueFoundry announced TrueForge on 2026-09-11 as a vendor-neutral open-source agent harness that runs on any model or MCP server, with a hosted pay-per-usage tier alongside the bring-your-own-keys release. The repo (truefoundry/trueforge, MIT) was created 2026-07-23, carries 5,405 stars, and was still shipping release candidates on 2026-09-12 (@truefoundry/[redacted]). The claimed 50% cost reduction is the vendor's own number and is not independently verified; the checkable part is that a credible open harness now exists in the slot OpenAI's Agents API and Claude Managed Agents occupy.
