updown is an online service that checks your website's status by periodically sending an HTTP request to the URL of your choice. It then notifies you by email or sms when your website is not responding correctly.
Read the updown.io story on indiehackers.Yes, there are a few existing alternatives but I was looking for a service really simple, cheap and nice looking. I couldn't find any, that's why I decided to build one the way I want. If you think something's missing, don't hesitate to leave your idea with the "feedback" button at the bottom.
