Is your site up? Check HTTP status, response time and SSL certificate expiry for any list of sites — straight from the terminal, in one color-coded glance. Zero dependencies, just Python.
I self-host my website on a Raspberry Pi, and the question "is it still up?" deserves a faster answer than opening a browser. upcheck pings all my sites in parallel and tells me three things I actually care about: is it reachable, how fast is it, and when does the SSL certificate expire — the one that always sneaks up on you.
It completes a little trilogy of terminal tools: pulse watches your machine, coinpeek watches the market, and upcheck watches your sites.
git clone https://github.com/0iroN/upcheck.git
cd upcheckThat's it. No pip install — it only uses the Python standard library.
python upcheck.py osmandemir.net github.com # check any sites (scheme optional)
python upcheck.py --certs mysite.com # also show days until SSL expiry
python upcheck.py -f sites.txt # read sites from a file
python upcheck.py -w 60 -f sites.txt # live view, refreshing every 60sThe exit code is 0 only when every site is healthy, so it drops straight into cron or CI:
python upcheck.py -f sites.txt || notify-send "a site is down!" upcheck · 4 site(s) · 21:15:00
● github.com 200 291 ms cert 53d
● osmandemir.net 200 196 ms cert 71d
● example.com 200 177 ms cert 80d
● definitely-not-real-site-9482.net DOWN - name not resolved

Healthy sites are green, client errors are yellow, server errors and unreachable sites are red. Certificates turn yellow under 30 days and red under 7.
- Sites are checked in parallel (up to 8 at a time), so a long list still finishes fast.
- A site file is one URL per line; blank lines and
#comments are ignored. --watchenforces a minimum 5-second interval to stay polite to your own servers.
