Ask HN: What cool projects did you build with serverless workers?

I finally managed to learn how to use Cloudflare's workers but still not sure what to use them for.

I have this feeling that this is a really cool tech that has a great potential automating stuff, but I can't figure out.

What are some cool projects did you build on top of them?

I used it for https://crates.live and it is the reason I'd always recommend it despite the stack being a complete mess. You set it once and it will always run. You don't have to care for a server. Most of my older projects died because I didn't have time to take care of the server. This fixes this one important bit and I think it's under-rated.

We used Cloudflare serverless to build several mini-apps for frontend. We liked that it was fast, and we could code in vanilla HTML. In fact, our favorite app was coded in less than an hour, and hosted on Cloudflare.

Here's the app demo: https://joshstroud.com/apps/spotify-notification

The page is hosted on Cloudflare within a single HTML file. Here's the code on GitHub: https://github.com/joshagilend/joshstroud.com/blob/9bece41b5...

Cloudflare serverless is free, often times. I like that a lot :)

We use Cloudflare Workers and Cloudflare KV Store for https://appflags.io/

It gives us around 100ms load time for our SDKs anywhere in the world even on cold boot.

I build notify a small serverless app with a pwa, that allows you to send web push notifications to your devices.

It was a cloudflare worker in the beginning (you can find it in the branches) but i rewrote it for deno deploy, since I found hosting cf worker locally (which was one of my goals) a pain.

I use it to calculate XIRR returns for my clients investment data. No more having to run a server to do occasional server intensive tasks.

Clouflare workers are a perfect use case for Node.js SSR apps - ultra fast, zero cold start, and pretty much free. I'm using it for an SSR app that's hitting a backend API hosted in AWS (.NET so not Cloudflare compatible) and it's just perfect.
