Uptime monitoring
farsee.dev checks your websites, TCP ports and mail servers on a schedule you choose, keeps the full history of every check, and opens an incident when something goes down — so you find out before your users tell you.
Free while in beta. No card, no trial timer.

Every status is shown as an icon and a word, never colour on its own.
Enough to answer "is it up, and how has it been lately?" without a dashboard you need training for.
Check a URL for the status code you expect and a keyword in the body, open a TCP port to see if it answers, or greet a mail server and require STARTTLS. One tool for the three things that usually break.
Every check is kept as a heartbeat, so you get uptime over 24 hours, 7 days and 30 days, a 90-day history bar, and a response-time chart with downtime shaded behind it.
File monitors under groups like Production or Infrastructure, create a group inline while adding a monitor, and filter the dashboard down to one group when you only care about part of the estate.
Pause a monitor during planned maintenance and the scheduler skips it — no noise, no false incidents. You can still run a check by hand while it is paused, and nothing you have already recorded is thrown away.
farsee.dev is in beta and free to use while it is. There is no paid plan yet and no billing to sign up for — create an account, add your first monitor, and see how it goes.
