Coding harness for AI agents
Helix
Helix runs locally. It takes one agent through all six stages of the agent factory, and your traces, prompts and datasets never leave your machine.
Helix
Coding Harness for AI Engineers
Build agents from any context
- Auto-generates a buildable spec from your context
- Scaffolds the agent and its eval suite together
- A signed spec you review before anything is built
Build eval coverage you can trust
- Datasets and evals derived from your real production traces
- LLM-as-a-judge calibrated to your experts, so scores stop drifting
- Coverage that grows with every new failure found
Diagnose why your agents fail
- Reads your production traces and root-causes every failure, automatically
- Turns each failure into a fix, an eval, or a guardrail
- Raised as a PR you review, never a black box
Goal based, eval driven optimization loops
- Set a goal and optimize against your eval suite
- Each round diagnoses, fixes, verifies, and re-scores against the goal
- Only real improvements ship, and you approve every one
Ship every release behind your evals
- Every release gated on your eval suite
- Prompt, model and config versions pinned, so you can roll back
- Lands as a check in the CI you already run
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.
