What each one is

The product in its own terms, so the numbers below have context.

Independently observed

Inngest

Inngest enables developers to write durable functions with built-in checkpointing and retry logic that survive failures. Functions execute step-by-step with automatic recovery and detailed observability, eliminating the need for manual infrastructure management.
