A tiny service that keeps my APIs warm

Serverless is great until the first person to visit your app in a while has to sit through a cold start. Nothing is broken, but the app feels slow, and slow is the impression people keep.

The fix is embarrassingly simple. Ping the thing so it never goes to sleep. I'd hacked together a cron job to do it on more than one project, and every time I set it up again I thought, why am I rebuilding this?

So I made FixColdStarts. You give it your API endpoint and it pings it every 5 minutes. That's the whole product. Your functions stay warm and your app stays fast for whoever shows up next.

I like projects like this. It solves one problem, it explains itself in a sentence, and I built it in a weekend.
