  • Best alternatives to Heroku in 2026
    Fly.io opens up two things Heroku keeps at arm's length: real multi-region deployment and full control over the runtime. Heroku's Common Runtime offers two regions (US and EU), and Private Spaces gets you one region at a time from a wider list. Fly runs Firecracker microVMs across eighteen regions on six continents, and replicas can be pinned to specific cities. If your Heroku app has global users and you've been... - Source: dev.to / about 1 month ago
  • Building an autonomous Slack agent with OpenCode
    The gateway is the web service that receives requests. I host it on Fly. It accepts Slack events, automation API calls, trigger requests, Composio webhooks, Inngest calls, and runtime calls. - Source: dev.to / about 2 months ago
  • It Worked on My Machine (Literally)
    The tunnel was never meant to be permanent (it runs off my laptop, and the URL changes every time it restarts), so the next step was deploying somewhere real. I built the Docker image for Fly.io, set my username, and shipped it. - Source: dev.to / 2 months ago

  • 3D models, avatars, gestures
    Unity is what they are using, I just know from seeing it in the browser code and researched it a little last year. https://unity.com/solutions/build-backend. Source: over 3 years ago
  • I teach Unreal. I had an easier time making my game in LittleBigPlanet. That cannot be right, what am I missing.
    I never said that Unreal is bad for non BRs, just that it is very good for BRs. The amount of work they put into making Fortnite work as well as it does puts it way above anything else for large match based shooters. I agree that Unity's old multiplayer code was an absolute mess, and I would have previously suggested using a third party solution. I was saying that I've heard good things about their new multiplayer... Source: about 4 years ago
