SpeedVault: Web performance & SEO your AI coding agent can fix.

Hey Product Hunt 👋 I'm Dragos. A few months ago I watched my AI agent build an entire feature in about 90 seconds. I was genuinely impressed — until I opened the page and waited. And waited. Four seconds for it to actually become usable. The code was "done." The site was slow. And nothing in that beautiful, fast workflow had any idea. So I did what everyone does: ran it through a performance tool. Got a score, a red number, and a polite list of "opportunities." Then I sat there realizing the tool had done the easy 10% — telling me something was wrong — and left me the other 90%: figuring out which thing mattered, how to fix it, and whether my fix even helped. That gap bothered me for weeks. We've automated writing the code. Why is making it fast still a manual chore you do in a separate tab, after the fact, if you remember to? SpeedVault is my answer to that question. I'm not going to spell out how it works here — honestly, the first time it did the thing, I grinned at my screen, and I'd rather you have that moment yourself. What I'll say is: the score is no longer where it stops. And it lives where you're already building, not in a dashboard you'll forget to open. It's free to try, no card. If you've ever shipped something fast that turned out to be slow, I think you'll get it in about two minutes. Go poke at it — then come back and tell me if it gave you the same grin. I'm here all day. 🙏

Web performance & SEO your AI coding agent can fix

Every performance tool tells you your site is slow, then leaves you to fix it.

SpeedVault closes the loop: it runs Lighthouse audits, pinpoints the exact issue, hands you the code-level fix, and re-checks that your score actually went up.

The twist it plugs into your AI coding agent over MCP. Claude Code, Cursor, and Windsurf can audit the page you just shipped, pull the fix, apply it, and re-audit on their own, in the loop, without you leaving the editor.

It's the whole stack in one:
