HumanLayer

HumanLayer is an AI-powered integrated development environment (IDE) and collaboration platform designed to accelerate software engineering workflows, particularly for teams working with complex codebases. It focuses on enabling engineers to ship code two to three times faster across the software development lifecycle while maintaining high standards for code quality and architecture. The platform integrates AI agents and structured workflows to support problem-solving and code delivery in enterprise-scale environments.

The system offers a workspace where tasks, agent sessions, artifacts, and worktrees are grouped, allowing for real-time collaboration among team members. HumanLayer supports managing tasks, running multiple AI agent sessions in parallel, and organizing all project artifacts—such as research documents, design docs, plans, and mockups—in a single, versioned, and shareable location. The platform emphasizes a comment-driven approach, enabling both humans and AI agents to collaborate on design documents and catch mistakes early in the development process.

HumanLayer is built around a structured workflow that guides teams through six phases: generating clarifying questions, researching codebases and dependencies, drafting design documents, structuring implementation steps, detailed planning with file paths and test cases, and executing implementation with continuous feedback. This workflow is designed to ensure alignment, transparency, and rigorous review at every stage, with checkpoints for human verification before moving forward.

Delivery options for HumanLayer include a local daemon that runs multiple agent sessions in parallel on a user’s laptop, as well as cloud daemons for long-running tasks. All activity syncs through the HumanLayer API, providing a consistent user interface across web, desktop, and mobile devices. The platform allows users to bring their own AI model subscriptions, supporting integration with services like Claude and Codex via API keys, and avoids separate per-token billing. HumanLayer is intended for use by software engineering teams, from startups to large enterprises, seeking to streamline collaboration and leverage advanced AI coding techniques in their development processes.
