Val Town is a collaborative website to build and scale JavaScript apps.
Deploy APIs, crons, & store data – all from the browser, and deployed in milliseconds.
This is a free, hackable uptime/downtime monitor that sends you an email when the site doesn't return a 200. It also stores historical uptime and latency data in your Val Town SQLite, which is used to power a status page. It supports multiple URLs in the same database and status page.
