Sentry is the best free error tracking tool. Its free Developer plan records crashes and errors from your website or app with the exact line of code and what the user did before it broke. GlitchTip is a free open source alternative that works with Sentry's code libraries. Paste the error into your AI coding tool to get a fix.
