Inngest

Event-driven durable execution platform for running reliable background jobs, workflows, and scheduled tasks. Functions stay durable by default with automatic retries, recovery, and step-based state management, so you can focus on business logic instead of queues or workers.

Trusted by teams at SoundCloud, GitBook, Aomni, and Otto. Inngest sets itself apart with infraless design: orchestration lives in your code via step.run and similar primitives, without extra infrastructure to deploy. Runs anywhere (edge, serverless, traditional servers), from any trigger (API calls, webhooks, cron), and supports TypeScript, Python, and Go.

Key capabilities:

• Step-based durable execution with automatic retries and fault tolerance across steps
• Flow control: concurrency keys, throttling, rate limiting, and prioritization for multi-tenant workloads
• SDKs for TypeScript, Python, and Go
• One-command dev server with instant traces and structured logs
• Built-in observability: replay failed runs, bulk cancellation, metrics
• Deploy to Vercel, Netlify, Cloudflare Pages, and other cloud providers

Common applications include AI agents and RAG pipelines with durable steps, email sequences and drip campaigns, user-defined workflow engines, and scheduled or event-triggered background jobs. Developers run npx inngest-cli dev for a local environment and integrate via events or HTTP endpoints without managing queues.
