Inngest is an open-source workflow orchestration and durable execution platform. It transforms any code into reliable background tasks and workflows capable of running for months and automatically recovering after outages. Inngest functions consist of triggers (events, crons, webhooks), flow control (concurrency, throttling, debounce, rate limiting, prioritization), and steps (the durable building blocks that survive incidents).

Designed for modern teams, Inngest provides SDKs for TypeScript/JavaScript, Python, and Go, and runs as well in serverless as on servers or at the edge. A dev server faithfully reproduces the production environment locally, and a dashboard offers complete observability: every execution, step, and retry is visible and replayable.

Self-hosted, Inngest is particularly suited for teams with data residency requirements or those wishing to avoid vendor lock-in with a proprietary platform, while retaining a reliable and observable workflow engine by default.
