HumanLayer

HumanLayer is an AI IDE, collaboration platform, and set of building blocks for a software factory. It is described for engineers working on hard problems in complex codebases, with the stated aim of helping teams ship faster while maintaining code quality and architecture standards.

The product centers on tasks, artifacts, and agent sessions. Tasks group sessions, artifacts, and worktrees in one workspace, and the interface is built around managing tasks, running multiple agent sessions in parallel, and collaborating with a team in the same place. HumanLayer also presents an opinionated system of agents for shipping maintainable code, with a workflow that includes generating questions, researching the codebase, drafting design documents, breaking work into implementation steps, planning with file paths and test cases, and then implementing with continuous feedback. Its materials are versioned, shareable, and tied to the task, and the page emphasizes comment-driven refinement and inline design reviews.

Delivery is split across a local daemon and cloud daemons. The local daemon runs many agent sessions in parallel on a laptop, while cloud daemons are available for long-running work. Activity syncs through the HumanLayer API, and the same UI is shown on web, desktop, and phone. The interface also includes a command palette for jumping between tasks, sessions, and artifacts. It supports bringing your own AI subscriptions or API keys, including Claude and Codex, and says there is no separate per-token bill.

The page says HumanLayer is used by everyone from YC startups to the Fortune 500. It also describes the system as an AI coding environment and software factory building blocks, and notes that agents can keep working even if the laptop is closed.
