I've built a small queue/cron service that you can use in your backend or serverless code to handle async (do it later) or scheduled jobs.

So many times I've had to hack a simple queue/scheduling solution based on MongoDB, Postgres, Redis or whatever data storage we had on the project. It was always not enough volume to justify deploying a dedicated solution, but tasks were important enough that we needed a persistent storage. You know, stuff like send out reminder emails, monthly invoices, cleanup old data, etc.

So I've built a small multi-tenant queueing service based on PostgreSQL, so I don't have to do it again.

My priority was that it is:

-> super simple to use (simple SDKs & REST api)

-> cheap and "pay as you go"

-> has "unlimited" plan, so you know your max price

-> has a nice UI to check what's going on with your jobs

Queueing engine is open source and you can check it out here: https://github.com/marekpiechut/pgqueue

It's currently in open beta and there's an SDK ready for JS/Express/Next.js with plan to add Golang and Java soon. You can register and test it out here: https://lambdaqueue.com

It would be great to get some feedback (good or bad) from HN community.
