About Kaihou Project
Kaihou Languages supports open-source projects through language and communication.
We help developers, small teams, and emerging initiatives overcome language barriers with translation, interpreting, and coordinated linguistic support.
Localization platforms like Weblate provide infrastructure. But one problem remains: who actually does the translations?
Most projects internationalize late — after they already have users, after the codebase is mature, after growth has plateaued in a single language.
We think it should work differently.
If a project partners with Kaihou from its beginning, it can start collaborating with international contributors immediately, in every language we support. It grows global from day one, instead of retrofitting translation once it’s already big.
Our Approach
Localization tools solve the technical problem. Translation agencies solve isolated jobs. Neither solves the coordination problem — having a team that grows with the project, understands its context, and stays involved over time.
Kaihou Languages is that team.
- A small, consistent group of translators
- Contributors who understand your project, not just your strings
- Ongoing collaboration, not one-off jobs
Our Philosophy
We don’t build software. We work closely with developers on the linguistic side of their tools, and build language infrastructure for projects that want to belong to the world from the start.
How It Works
Kaihou Languages follows a simple and sustainable model.
Open projects get 100% free services, no obligations, and direct collaboration with a linguistic team — ideally from day one. We integrate into your existing workflow, whether that’s Weblate, self-hosted tools, or a simple custom setup.
Private clients get affordable translation, interpreting, and linguistic support. This is what sustains the project, lets us improve continuously, and keeps our support for open initiatives genuinely free.
Free for open projects. Sustained by private work.
