Same tasks. Lower cost.

14 production-style agent tasks, run end to end. With the same model, TrueForge cuts cost by 30%. Switch to an open model and save up to 75% - without sacrificing accuracy.

Own Your Agent Stack.

A managed harness shouldn't decide which model you run.
TrueForge doesn't.
Image
Bring Any Model
Use Β commercial or open models. Switch models per task without rebuilding your agent.
Image
Bring Your Sandbox
Run agents in your own sandbox and compute environment. Keep execution where you want it.
Image
Connect Any Tool
Connect any MCP server or API. Use the tools your workflows already depend on.
Image
Open Source
Self-host anywhere. Keep your agents portable across models, tools, and infrastructure.
ImageImage
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.

TrueFoundry has become the central platform in IT where agentic apps and agents are routed through. We are onboarding more users and teams every day and it's fundamentally changed how quickly we can get an agent from idea to something running at scale

Capabilities
Image

Everything you need for production-ready agents

Image
Sandboxed execution
Agents run code, touch files and execute long tasks inside an isolated sandbox with scoped credentials. Nothing escapes the boundary you set.
Image
Human-in-the-loop approvals
Sensitive tool calls pause until a human signs off. Gate destructive actions once, centrally not per agent.
Image
Generative UI streaming
Agents stream structured blocks; your client renders live UI instead of walls of text.
Image
Skills registry
Step-level traces end to end every model call, tool call and token accounted for, in the same pane as your gateway traffic.
Image
Memory and state
Durable state for long-running tasks. Runs survive restarts and resume where they left off.
Image
Observability and tracing
Step-level traces end to end every model call, tool call and token accounted for, in the same pane as your gateway traffic.
Image
Context engineering
Subagents, preload tools, large-result offloading and automatic compaction keep the context lean the biggest lever behind the token numbers above.
Image
AI Gateway
Image

Connect everything through AI Gateway

TrueForge plugs into TrueFoundry's AI Gateway. Agents reference models, tools and skills by name; credentials, RBAC and budgets stay in the gateway plane.
Image
MODELS
1000+ LLMs
Every provider behind one endpoint, with model-level RBAC, budgets, routing and fallbacks.
Image
MCPS
Governed tools
Centralized auth, in-chat OAuth, per-user delegation. Every tool call logged and policy-checked.
Image
SKILLS
Skills registry
Versioned SKILL.md instructions with RBAC, mounted into the sandbox on demand.

Frequently asked questions

What is TrueForge?

It's an open-source agent harness. It takes a model and everything around it (tools, sandbox, memory, approvals) and turns it into an agent you can actually run in production, on your own infrastructure.

Is it really open source?

Yes, all of it, under MIT. It's not a cut-down free tier with the good parts held back. The whole runtime is in the repo.

How is it different from Claude Managed Agents?

Claude Managed Agents only runs Claude, on Anthropic's cloud. TrueForge runs whatever model you want on your own infra, and came out around half the cost on the same benchmark.

How is it different from LangGraph, CrewAI, or Deep Agents?

Those are libraries you write code with and host yourself. TrueForge is a harness you build agents on from the UI or SDK and run in production, with sessions, governance, and triggers already there.

Is it cheaper, and compared to what?

On the same tasks and the same model, it ran about 50% cheaper per run than Claude Managed Agents, and cheaper still if you point it at an open model, with no drop in answer quality. (benchmarked on DevRev's Enterprise-Bench, graded blind.)

Do I need TrueFoundry's AI Gateway to use it?

No. TrueForge works standalone; connecting the gateway adds governed access to 1000+ models, MCPs and skills.

Who is it for?

Anyone from a solo dev who wants an agent running in one command, to a platform team taking a prototype into governed production.

What does it cost?

The harness is free and open source. You pay only for the models you route to.
