A while ago, I posted my startup here, BackendLab, which was in public beta at the time. I had a lot of very valuable feedback from this community, and have pivoted the product slightly since then
I just launched the first official release of BackendLab, which is now taking paid subscriptions.
I'm also offering an introductory 50% discount on the pro plans for the first year - details can be found on the Product Hunt page here: https://www.producthunt.com/posts/backendlab-beta
Thanks for looking! Chris
