Windmill - https://github.com/windmill-labs/windmill

Inngest is very cool, and if you are interested in the topic but absolutely want to self-host, 2 other high-performance durable execution engines that enable all the above and that you can self-host and are open-source and mature would be temporal and windmill. Both can use postgresql as the queue (temporal can use cassandra too), the rest can be done leveraging the transactional properties of postgresql, such as atomic counters for the concurrency keys: https://github.com/windmill-labs/windmill/blob/main/backend/... or re-queuing jobs that haven't progressed when they should have (most likely, worker crashed). There are very cool things you can do today without too much complexity with the primitives that modern database are capable of. Should one rebuild it for their startups, no, but if you were to extract the very core of the durable

Look very similar to the script builder portion of https://github.com/windmill-labs/windmill, but not open-source, not self-hostable, without open-source integrations (https://hub.windmill.dev/) and without a workflow engine disclaimer: I'm founder of ^

For an alternative to airplane.dev, you can checkout Windmill. https://github.com/windmill-labs/windmill "Open-source developer infrastructure for internal tools (APIs, background jobs, workflows and UIs). Self-hostable alternative to Airplane, Pipedream, Superblocks and a simplified Temporal with autogenerated UIsm and custom UIs to trigger workflows and scripts as internal apps. Scripts are turned into sharable UIs automatically, and can be composed together into flows or used into richer apps built with low-code. Supported script languages supported are: Python, TypeScript, Go, Bash, SQL, and GraphQL.
