Open Source
Swatter
A Cloudflare-aware abuse blocker for cPanel servers. Scores web-log IPs on behavioral signals and blocks attackers on the right firewall plane — CSF or ipset — so it can never firewall a Cloudflare edge and take your sites down. Now with Swatter Swarm — a self-hosted fleet reputation network that shares confirmed bans across your servers. Free, MIT licensed.

Open Source
Foghorn
A dead-man watchdog for your server, not another status page. One cron-triggered Cloudflare Worker, one source file, and one text message when your box actually goes down — plus one more when it comes back. Zero KV writes while healthy, so it runs on Cloudflare's free tier forever. Free, MIT licensed.

Coming Soon
ZoneGrade
Read-only Cloudflare fleet monitoring for agencies and MSPs. Connect accounts with read-only tokens, get an A–F report card for every zone — completeness, drift, security — and let scheduled sweeps catch configuration drift before your clients do.

Peace Harbor Studios is the app studio of Peace Harbor Companies — a creative, web, and print shop in Sandpoint, Idaho building for businesses, ministries, and creatives since 2003. The studio is where that two-decade habit of shipping durable, well-made work turns into software of our own.
We build the tools we needed ourselves. Swatter came out of running real cPanel hosting behind Cloudflare and watching ordinary blockers either do nothing or firewall the edge and take a whole box offline. We keep the surface area narrow on purpose — independent, built on Cloudflare for speed and durability, each release earning the attention it asks for.
Founded and built by Josh Comstock, owner of Peace Harbor Companies and a security & privacy advocate in Sandpoint, Idaho. Find him on GitHub, LinkedIn, and X.
