Products
Built to ship agents, and keep them working
Helix
Coding harness for AI agents
Runs locally and takes one agent from spec to shipped, on your machine.
Agent Factory
Open infrastructure for agent factories
Helix in a cloud sandbox. The same feature set, always on, so a fleet of agents keeps working.
Architech
Research previewSoftware factory
Runs your SDLC. Plan, build, test, review, ship, monitor and triage, independent of the coding harness.
CleraBuild self-improving agents with Helix
Diagnosed in a real production agent: a cost teardown of Clera’s outreach agent, and the one fix that reversed it.

Runs locally. You keep your data.
The agents run where your code already lives, not on our servers.
Your data never leaves your machine
Your traces, prompts, and datasets stay on your infrastructure. Nothing is sent to us.
No lock-in
Your model, your frameworks, leave whenever. OpenAI, Claude, LangChain, Mastra, your own stack.
FAQ
Those tools observe and score. Mutagent is a team of agents that act on what observability shows: Spec, Build, Diagnose, Benchmark, Optimize, Validate, Deploy, Watch. Keep Langfuse or LangSmith for production telemetry. Run Mutagent agents à la carte, or let the full lifecycle run end to end. Same flexibility for your stack, your models, your workflows.
DSPy and GEPA are search algorithms. Mutagent is a team of agents you run alongside the rest of your stack. Each agent owns a phase of the lifecycle, and each can be invoked on its own, chained, or swapped. Bring your own optimizer if you want one. The point is a coordinated team that covers the full lifecycle, not adopting one fixed pipeline.
Full CLI access. Integrate, Bootstrap, Analyze, and Optimize on up to 3 prompts. Bring your own model. No credit card required.
Agent runtime is not yet available. Multi-agent optimization is in co-development now. Self-host ships Q3 2026. Everything else is live.
