One more thing

Built for readers, driven by the community

Oboku is under active development with new features shipping regularly. We prioritize what users ask for — if you love the app and want something, let us know. There is no better motivation than knowing someone will benefit from it.

The project is free, open source, and ad-free — and we intend to keep it that way. Donations and sponsorship will be available to help sustain the project. The cloud version will stay online for as long as we can cover the infrastructure costs.
