Team chat, rebuilt for developers

We started Hazel because we believed developer teams deserved a communication tool that understood their workflows — not one that bolted on integrations as an afterthought.

Our mission

Modern developer teams are spread across time zones, juggling dozens of tools, and drowning in notifications. Existing chat platforms were designed for general business use, not for the unique way engineering teams work.

Hazel is different. We built a communication platform that natively understands developer workflows — GitHub PRs, Linear issues, deployment pipelines, and code. No plugins, no third-party bots, no configuration headaches.

We believe the best tools are open source. That's why Hazel's code is fully public, auditable, and community-driven. You can self-host it, fork it, or contribute to it. No vendor lock-in, ever.

What we stand for

Open Source First

Our code is public. Our roadmap is public. We build in the open because transparency creates trust, and trust creates better software.

Speed Matters

Every millisecond counts. Hazel is engineered to be fast — fast to load, fast to navigate, fast to message. No loading spinners, no lag.

Developer Experience

Keyboard-first navigation, inline code highlighting, native integrations. We design for the way developers actually work, not for slideware demos.

Join the community

Hazel is built by a growing community of developers who believe team communication can be better. Whether you're a user, contributor, or just curious — you're welcome here.
