Known issues
For Improvement
Max 25 monitors to watch in case you are using Slack notifications, due to the limit of subrequests Cloudflare Worker can make (50).
The plan is to support up to 49 by sending only one Slack notification per scheduled run.
KV replication lag - You might get Slack notification instantly, however it may take couple of more seconds to see the change on your status page as Cron Triggers are usually running on underutilized quiet hours machines.
Support for Durable Objects - Cloudflare's product for low-latency coordination and consistent storage for the Workers platform. This tool should support the free tier.
Backlog
Initial delay (no data) - It takes couple of minutes to schedule and run CRON Triggers for the first time
Github Actions - This repo is a monorepo build with pnpm. link The wrangler 2 action has some problems with the installation of jq.
Worker Deployment - It is possible to get false positives due to the nature where the cron job is executed. Cron Triggers are usually running on underutilized quiet hours machines
