TrueForge open-sources vendor-neutral agent harness, cutting costs up to 75% vs Claude managed agents

TrueFoundry open-sourced TrueForge, a vendor-neutral harness for building general-purpose agents. It handles the runtime pieces that get painful quickly: context management, tool/MCP execution, subagents, sandboxing, approvals, and persistent state.

They also benchmarked the harness itself: with the same Opus 4.8 model, TrueForge delivered a similar solve rate at roughly 30% lower cost than Claude Managed Agents; switching to an open model pushed savings to about 75% on the same benchmark.
