Everything you need to keep your project online
Reliable tooling to monitor documentation, public APIs, and packages without hassle.
Monitor your open-source project online presence
Monitor your documentation site, API, package registry, demo app, GitHub Pages site or whatever else your users depend on.
- Keep documentation sites and GitHub Pages reachable for developers and users.
- Validate live demo APIs, sandbox environments, and package registry mirrors.
- Check availability every 30 seconds from independent European infrastructure.
- Get alerted via Slack, Discord, Telegram, or email before users file GitHub issues.
A status page for when things go sideways
A public status page gives contributors and users one official place to check what is going on, avoiding GitHub issues and Discord chats to fill up with duplicate bug reports.
- Show live operational status across your services, APIs, and public demo tools.
- Publish active incident updates while maintainers investigate and ship fixes.
- Host on your own custom domain with automatic SSL at zero cost.
Incident triage without the panic
Coordinate incident response, keep everyone updated, and get from “uh oh” to “all good” without messy spreadsheets or pinging maintainers at 2am.
- Track SSL certificates and get warned well before they expire or break.
- Schedule maintenance windows to avoid false alarms during planned upgrades.
- Invite maintainers and contributors without worrying about per-seat charges.

Phare-tastic feedback
They all came for a free uptime monitoring tool, they stayed for the superior platform, and the vibe.
Phare can be described simply in two words: Absolutely amazing.
I think Phare has a very clean and to the point interface and feature list. I use for my personal projects right now but I am considering it for work related things as well.
I simply love it. The UI is very clean and clear. You only pay what you use. That is for every request that is made. You can even adjust the frequency for each monitor individually. However, for me the best feature is the well-documented API that makes it possible to embed phare.io into your existing infrastructure in no-time.
It has all the important features and its UI is just lovely!
Nice UI, clear UX, custom domain, custom status page. I sign up and 5 minutes later I get : - 2FA secure auth - A nice status page on my own domain - Telegram & email alert working The product is simple and powerful, I love it. Bravo !
We’ve been using Phare for months now, and the dev is actively working on improving the system! He responds to messages and even reached out to us when we didn’t know there was a problem. We’ve used lots of systems and by far this takes the cake and works perfect for what we need.
Checked many, many competitors, and Phare is fairly the best option to go with!
Phare offers a nice status page that is incredibly easy to use. It’s free to play, no credit card required. Incident management has internal and external communication.
It’s a great product, I was able to participate in the beta and it’s really a great project, I’m very happy that we have a solution like that in Europe. Can’t wait to see what happens next.
Amazing uptime management! Works automatically and notifies me via email.
Super slick. Ridiculously simple to setup. Took me a minute to figure out where the badge was but otherwise this was setup in a blink of an eye.
