Architecture

One loop. Everything governed.

The harness owns the run: planning, tool routing, sandbox lifecycle, approvals and tracing. Models and tools are referenced by name, credentials never live in agent definitions.

Architecture

Same tasks. Smaller bill.

14 production-style agent tasks, run end to end. Hold the model fixed and the harness alone cuts cost 30%. Route to an open model and cost per correct answer drops 5×.

Vendor Neutral

Your models. Your tools.

A managed harness shouldn't decide which model you run.
TrueForge doesn't.

Any Model, Per Task

Claude, GPT, Gemini, or an open model routing is a setting, not a re-platforming project. Tasks that don't need a frontier model aren't billed like they do.

Bring your own tools

Any MCP server, any API. Tools are referenced by name and governed centrally no proprietary tool format to rewrite against.

Open source, self-hostable

Run it in your VPC or on-prem. The loop, the sandbox and the traces live where your data lives.

No exit tax

Agent definitions are portable config instructions, skills and tool names. Leave any time and take everything with you.

Building an agent is the easy part; running it safely in production is where teams get stuck. TrueFoundry gives us one place to build, run and govern our agents, and put them in front of our brokers with the guardrails and visibility we need.
