// EDITOR'S TAKE
Sentry matches Bugsnag feature for feature on grouping, breadcrumbs and release health, but the self-hosted install is genuinely heavy to operate. Bugsink is the pragmatic alternative since it speaks the Sentry SDK protocol, runs on one small server and does error tracking only, while SigNoz and HyperDX are full observability platforms that treat errors as one signal among traces and logs.
