Self-hosted error, performance and slow-query monitoring for PHP 7.0–8.4 (Laravel, Symfony, CodeIgniter, Yii2), Node/Express/NestJS/Next.js, React, Vue, React Native, Expo and Flutter. Every error keeps its request, user, session, breadcrumbs and a masked screenshot. AI explains the root cause in your language, and a GitHub App opens a pull request with the fix on a bugban/fix-… branch — merging stays yours. Slow queries arrive with EXPLAIN and can be re-measured safely on your own DB.
