Inngest

Inngest is a durable execution platform that developers embed directly into their own applications to run reliable background jobs, workflows, and AI agents. Functions are broken into steps that Inngest checkpoints and persists, so if a step fails it retries from that point instead of restarting the whole function, and a workflow can pause for seconds or months without polling loops or a separate worker process running in the background. It targets developers building AI agents, scheduled jobs, event-driven systems, and API endpoints, with SDKs for TypeScript, Python, and Go, and it runs inside a team's existing serverless, container, or traditional server setup rather than requiring dedicated infrastructure. Features include flow control such as rate limiting and per-tenant concurrency, plus tracing and replay for observing agent behavior. Inngest also publishes official plugins for AI coding assistants such as Claude Code, Cursor, and Windsurf that give the assistant current, accurate information about Inngest's own API rather than relying on outdated training data. The company states SOC 2 Type II compliance and offers a HIPAA BAA for regulated customers. Inngest is a piece of developer infrastructure that must be integrated into code, so it is not aimed at non-technical users looking for a ready-made app, and specific pricing tiers were not detailed on the pages reviewed.
