What StatOSS does differently
Most uptime pages show a row of green squares, one per day, and a percentage. A five-minute outage at 3 a.m. becomes a square that is still green and a figure that still says 99.99%. StatOSS draws a strip per monitor where every bar is one check, its height the response time, amber for a timeout and red for any other failure, and groups the failed checks into entries with the time and the reason. The mark stays visible for the whole range. A customer who was refused at 3 a.m. finds the moment on the page, and so do you.
Before a failure counts, a second server on another network repeats the check, and only a failure both see goes on the record; two of those in a row make an outage. The response time of every check is kept, and a slow threshold turns a sluggish service into its own state with its own alert. The core is open source under MIT, so the page you get from the hosted service is the page you can run yourself.
When Gatus is the better pick
If your monitors live in Git next to the services they watch, Gatus reads them from one YAML file and needs nothing else. If you need SSH, WebSocket or UDP checks, conditions on JSON fields, or SMS through your own Twilio account, Gatus has them. It runs as one small binary inside the network it watches, so it reaches internal services.
Where StatOSS fits: a hosted page that stays up when your network does not, failures checked again from every region, email and webhook subscribers, incidents and post-mortems written on the page, and a free plan. The standalone is one container configured with a YAML file too.
