"I’ve been running a small web agency for almost 2 years. One thing I wanted was a simple way to keep track of client websites in case they went down. The existing tools felt too heavy for my needs, so a few weeks ago I decided to build my own.

In 3 weeks went from scratch to a working product. It’s nothing fancy yet, but it works great for me! It monitors websites every 5 minutes, sends alerts to email, and has a clean dashboard. Very minimalistic, you can set it and forget it. It just works. Like a smoke detector you only think of it when your really need it.

The main reason I built it was to solve my own problem, but I thought it could be useful for other freelancers or small agencies too. Hence; I've put out an open beta to the public as an MVP to see if there is any demand for it.

You can check it out here: sitepuls.app I'd love feedback, insights and constructive critisism!

Happy to answer questions about the build process, tech stack, or what I learned along the way (I learned a ton).
