We saw this coming (like most people) a while ago when Heroku started flaking without status updates, and moved part of our workload to Fly. We ended up moving off Fly as well (significant unreliability and just some very strange network load balancer issues that would cause us downtime) and went to Railway, and that's been fantastic so far. We've moved our whole workload onto it.

Moved from heroku to fly.io three years ago and I don’t regret it, great platform occasionally goes down and requires a bit of attention but the support forum is great

Digital Ocean App Engine has the easy setup and GUI management that made Heroku popular.

If you like VPS, Hetzner with Dokploy. It works great, the UI has essentially all the features of Fly or Render that you'd use for deployment, like preview build URLs and environments.

Build.io came out of this exact problem a few years ago (I joined in 25Q4) - trying to be what Heroku could have been if it had continued to evolve.

We offer the same default simplicity/speed, but with the ability to go deeper once teams hit scale, cost, or workflow limits. Plus a pricing model that stays understandable and improves as teams scale rather than punishing them for it.

Fair warning: the website is pretty light right now. It’s mostly a placeholder while we prep a broader push over the few months. Happy to answer questions here if helpful.

Kamal works well
