What is Inngest?

Inngest is a developer-focused code automation platform designed for building reliable event-driven workflows with zero infrastructure. The platform provides a low-latency workflow engine that handles over 100 million daily executions, enabling developers to build durable workflows with automatic retries on failed steps, step-based functions for easier debugging, and built-in scheduling without external tools. Inngest's event-driven architecture triggers functions based on real-time events and includes comprehensive flow control tools to manage concurrency, set prioritization, rate limiting, debouncing, and handle idempotency. The platform integrates seamlessly with modern development tools like Vercel and is available on AWS Marketplace, making it particularly well-suited for teams building scalable backend workflows and AI-powered applications.
