Fn Project vs Inngest

Both stand on serverless platforms. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Inngest provides durable execution, observability, and flow controls for asynchronous workflows. The Free plan has defined execution and trace limits, and execution pauses at the quota until the account upgrades.
