A complete self-hosting guide is coming when BuzzKit is out of beta. Until then, use buzzkit.dev.
What it will need
A deployment needs a Cloudflare account for Workers, KV, Queues, Durable Objects and Hyperdrive, together with PostgreSQL and Tinybird. Provider credentials, such as an Apple Developer key or a Firebase service account, are uploaded through the dashboard rather than set as environment variables. We plan to simplify this setup before the guide lands, so treat the list as the shape of the thing rather than a checklist to work through.buzzkit-dev/buzzkit
The repository. Its README carries the current state of setup.
Licensing
The core is AGPL-3.0: the API, the dashboard, the marketing site and the internal packages. The SDKs your customers embed are MIT, both thebuzzkit server package and the iOS SDK, so shipping them inside a closed-source application carries no copyleft obligation.
