Live, and free.

Paste the error. Get the fix.

CoolFix is a free tool. You paste the Coolify deploy error you’re stuck on, and it gives you the exact step-by-step fix. No sign-up, no waiting on a forum reply at midnight.

The fixes come straight out of the same playbook I use on my own client hosting, so they’re the steps I’d actually run, not generic advice.

If you’d rather not touch the terminal at all, that’s what the studio is for. I’ll fix the deploy, get your site live, and look after the hosting so it stays that way. The button below starts that conversation.

Stuck on a deploy? I’ll just fix it.
