HumanLayer

A multiplayer control plane for AI coding agents

Multiplayer Tasks

Bundle agent sessions, artifacts, and worktrees into a shared Task that your whole team can open, comment on, and collaborate around.

QRSPI structured workflow

Six phases from clarifying Questions through Research, Design, Structure, and Plan to Implement, each with checkpoints your team can verify before more code is generated.

Comment-driven design review

Inline comments on versioned design docs let humans and agents negotiate the approach in real time, catching architectural mistakes before implementation.

Local and cloud daemons

A local daemon runs many sessions in parallel on your laptop, while cloud daemons handle long-running background work that survives closing your machine.

Strengths & Pros

+Structured QRSPI workflow keeps engineers in control instead of outsourcing thinking to agents
+Design docs and comments feed directly back into agent context, so decisions actually reach the code
+Runs locally or in the cloud with consistent UI across web, desktop, and phone
+Composable by design: bring your own model harness, compute, and dev environment
