BuzzKit

Open source notification orchestration layer for mobile push — send, segment, schedule and automate on your own Apple and Firebase keys.

BuzzKit: In beta, open to join. Get it at buzzkit.dev.

BuzzKit is an open source notification orchestration layer designed for developers who want full control over their mobile push infrastructure. It lets teams send, segment, schedule, and automate notifications using their own Apple and Firebase credentials — self-hosted or cloud-hosted — with no shared provider accounts and no message markup. BuzzKit supports event-based workflows with waits, conditions, and follow-ups requiring zero custom code, plus built-in user preference management, quiet hours, daily limits, and per-timezone scheduling. Multi-tenant by design, each customer workspace gets isolated subscribers, topics, and credentials. A lightweight SDK handles token management automatically, and integrations or webhooks connect existing tools to trigger notifications seamlessly.
