ᛗMERLIN
Harness online · skills compounding

The agent harness that
learns from its own runs.

MERLIN turns execution evidence into permanent capability — verified skills, isolated subagents, fleet orchestration. Not a wrapper around a model. An operating discipline.

What makes it different

◈

Evidence-driven

Every skill edit is verified against a deterministic eval suite. No claims without a green run.

⬡

Compounding skills

Lessons captured from real sessions become permanent procedures — the harness gets cheaper every run.

◇

Fleet native

Multi-machine orchestration across Windows, WSL and edge nodes. One operator, many workers.

◉

Isolated subagents

Parallel children with typed contracts, structured output and depth-bounded delegation.

Start free. Upgrade when it pays for itself.

Free tier for exploration. Pro for unlimited runs and fleet access. Founders lock the price for life.
