Yes. The self-hosted version is free and fully featured. There is no paid tier for self-hosting and no features are withheld from it. You provide your own model API key (or a local model) and run it on your own infrastructure.
Not today. If a managed hosting option is offered in the future — for people who don’t want to run it themselves — it would be paid, because hosting and AI inference cost real money. That would be a convenience service; self-hosting stays free and complete regardless.
You can, but AGPL-3.0’s network-copyleft applies: if you run a modified version as a service, you must make your modified source available to its users. Review the AGPL-3.0 terms before doing so.
Yes. Contributions are accepted under AGPL-3.0 and require a one-time signing of our Contributor License Agreement (CLA.md) — you sign by commenting on your first pull request; a bot walks you through it. The CLA lets the project keep the door open to offering a first-party managed-hosting service later while everything stays open source.
AGPL keeps the project open while preventing anyone from taking it closed-source as a hosted service. It fits the project’s privacy-first, self-hosted ethos: improvements flow back to the community.
