So far I’ve put all the side projects I manage (5 of them) and it’s working great. I can follow and query the logs, the JSON payloads by path, see live metrics like number of users currently online, etc. Even if I don’t get any customers I’ll continue developing it for my own needs! Will soon be adding alerts through webhooks, slack, discord, etc.
If you want to try it out: https://app.getboringmetrics.com (no landing page yet).
Edit: just want to say that if you want to try the software but not keep it, you can create an account in under 10 seconds, send a curl request to see logs arrive in realtime, and delete your account in 5 seconds. I do not track anything and do not keep a single piece of data.
