Cloud 66

Cloud 66 takes a different approach to the problem: it creates an environment like Heroku but on your servers on any cloud. This creates many benefits, including persistent storage and support for all available regions of your cloud provider of choice. But it also makes a big difference in availability: your application is not dependent on Cloud 66’s availability and won’t go down, even if Cloud 66 is having issues (you can see their uptime page here).

Cloud 66 is not as close to Heroku as, say, Render, but it hits the sweet spot between the lower cost of running your servers and the convenience of Heroku.

Pros

• Best of both worlds: low cost but convenient like Heroku
• Persistent storage
• Wide database support + bring your own database
• No downtime dependency (see above)
• If you have credits with a cloud provider, you can use it with Cloud 66

Cons

• With more flexibility, there might be more things to take care of than the hands-off approach of Heroku
• Without pre-allocation of resources, scaling up can take minutes.
