I Built a tool to help with those surprise Cloudflare bills

So I was researching here and many people have posted about getting bills and not knowing when and what caused it.

So I decided to build FlareLens.

It monitors your Cloudflare usage and catches abnormal spikes early traffic. Bandwidth, cache, threat traffic. Before they turn into a surprise bill. It alerts you on Slack, Discord, email or PagerDuty so you can actually do something about it in time.

Its built and runs on Cloudflare Workers and uses everything from Cloudflare. No third party infra, nothing leaves Cloudflare.

Its open source so the community can support and build it. Check it out here https://github.com/Thelastpoet/flarelens and the live site https://flarelens.site

Would love feedback especially from people who have been hit with those surprise bills, this is basically built for you.
