We build open-source
tools for & the people who make, ship, ship again.
Hitosea (海豚有海) is a studio of three bets and one stubborn belief — that the most durable software is built alongside its community. From team collaboration to agentic coding to vertical AI, our suite is open at the core and production-grade at the edges.
Three bets, one engine.
We cluster our products into three coherent groups — each addressing a distinct layer of modern work — and sharpen every one with the same platform team.
For teams that build together.
Self-hostable project, task, and OKR tooling that keeps work synced across timezones.
For the people who ship code.
Agentic IDEs, cross-platform runtimes, and delivery infrastructure for developer teams.
For the real, messy world.
Narrow AI products solving specific, human problems end-to-end — not chatbots.
The best software is built with, not behind, its community.
Every Hitosea product ships with a permissive license, a public roadmap, and a steady cadence of changelogs. When you adopt Hitosea, you inherit a codebase — and a community that reviews it every day.
We take pull requests like we take bug reports: seriously, quickly, and with a reply from a human engineer. No gatekeepers, no enterprise-edition traps.
Four principles we refuse to compromise on.
We optimize for a specific kind of customer: engineering-led teams that value transparency, self-hostability, and the right to leave.
Fully Open Source
Every product is public on GitHub under a permissive license. Fork it, audit it, self-host it — no permission required, no enterprise-edition gotchas.
Enterprise Ready
SSO, audit logs, and on-prem deployments ship from day one — serving finance, government, and regulated industries with production-grade defaults.
A Product Suite
One design language, one identity layer. Adopt one to start — integrate the rest when you are ready. No forced platforms.
Developer First
Everything has an API, a CLI, and a webhook. We sweat the DX so your teams spend their time shipping — not configuring vendor dashboards.
