Self-host in minutes
One curl | bash, one domain, one docker compose up. Postgres, NATS, Valkey, MinIO and Caddy with automatic HTTPS are bundled. See Install.
One app for how your team works
Kern bundles issue tracking, chat, a collaborative wiki, HR, outbound mail and an asset register into a single self-hostable platform — many workspaces, one login, one notification inbox.
Modular by design
Every capability is a module with a contract, a server part and a client part. Enable or disable them per workspace. Read Modules.
Many workspaces, one inbox
Users belong to any number of workspaces and see notifications from all of them in one place. Learn the core concepts.
Built for developers
Typed contracts (Zod + oRPC), OpenAPI 3.1 for every module, a realtime protocol and a module SDK. Start with the architecture.
