Handler.dev started with a simple observation: developers are running more AI coding agents than ever, but the tooling hasn't kept up. You end up juggling terminal tabs, losing context between sessions, and hitting your laptop's limits when you try to scale.
We built Handler to be the command center for this new workflow. A visual canvas where you can see all your agents at a glance. Instant environments that boot in seconds. Session persistence so your agents keep working while you sleep.
Handler is open source under the MIT License because we believe developer tools should be transparent and community-driven. The self-hosted version is free forever.
Make AI-powered development accessible, scalable, and delightful. We're building the infrastructure layer that lets developers focus on what matters — shipping great software — while AI agents handle the heavy lifting.
