What is Inngest?
Inngest is a platform for running workflows and agents durably, without managing orchestration infrastructure. Add steps to functions in your existing code, and Inngest executes and stores each step and retries from the failed step. It also provides flow control, observability (traces), isolated sandboxes (microVM), and agent evaluation and A/B testing. It offers TypeScript, Python, and Go SDKs and a REST API; you develop with a local Dev Server and then run in the cloud or on a self-hosted server.
- Background jobs with automatic retries, recovery, and observability
- Durable message queue without Redis or a broker
- Scheduled and cron jobs that can sleep, fan out, and retry
- Per-tenant concurrency, throughput, and fairness flow control
- Run code in isolated microVMs inside durable executions (Sandboxes)
- Result scoring and A/B comparison (Agent Evals)
- Real-time streaming of run progress
- Full trace from trigger to completion
Who uses Inngest and for what
- AI agent loops that need tool calls, human waiting, and failure recovery
- Multi-step background jobs that retry only the failed step
- Evaluation and A/B testing of prompts, models, and workflows
