As answered by people managing CodePen and itbroke.dev.
itbroke.dev's answer:
Currently monitoring vpn.com, tracking 218,000+ events per month across thousands of pages.
itbroke.dev's answer:
PHP 8.2, SQLite, vanilla JavaScript. Hosted on DigitalOcean, served behind Cloudflare. The tracker is a lightweight script under 4KB.
itbroke.dev's answer:
After building a dozen projects, I wanted to commit to something with a longer lifespan. I kept running into the same problem: error tracking tools told me things were broken, analytics tools told me conversions were down, but nothing connected the two. itbroke.dev was built to answer one question automatically: is this error costing me money?
itbroke.dev's answer:
Website owners and small teams running ecommerce stores, affiliate sites, and startups. People who need to know if their site is silently losing sales, not developers debugging backend infrastructure.
itbroke.dev's answer:
One script tag, live in seconds. Form conversions tracked by default. No SDK, no build step, no configuration. Errors are ranked by how much revenue they're losing you. Free forever plan with every feature included. If you've ever stared at an error log wondering which bugs actually matter, this answers that question automatically.
itbroke.dev's answer:
It automatically connects errors to conversion impact. Other error monitoring tools tell you what broke and how often. itbroke.dev tells you which errors are costing you revenue, ranked by business impact, not frequency.
