Render is great but doesn’t offer a long-term usable free tier for database-backed projects.

However, if you’re looking to move a project that costs you money off Heroku, you’re likely to be quite happy with the price-performance ratio that Render offers. I certainly am.

I have just recently deployed a small Rails project on Render and I really like it so far. Good docs, great UI.

Good UI with great stats, but stopped using after few days 'cause the builds are painfully slow.
