Best Self-Hosted Alternatives to Sentry
Sentry is the default answer for error tracking, and its event-based pricing is fair right up until a bad deploy turns one noisy exception into a six-figure event count. Self-hosting official Sentry is famously heavy — its own compose stack wants serious hardware and care. The trackers below take a different path: they speak the same Sentry SDK protocol your apps already use, so you change a DSN, not your code, and the exception stream lands on a server you own.
Sentry costs about $312/year and keeps your data on its servers. These researched, open-source alternatives give you the same workflow on hardware you own — here's what each needs to run.
The alternatives
What you give up by leaving Sentry
Leaving hosted Sentry means giving up more than hosting: its performance monitoring, profiling, session replay, and release-health tooling are far ahead of any lightweight alternative, and its SaaS handles ingest spikes you never have to size for. GlitchTip keeps the core workflow — errors, basic performance monitoring, uptime checks; Bugsink strips it to exceptions-only in a single container. Both accept the official Sentry SDKs, so the migration is a DSN swap — and the way back is the same swap in reverse. What you take on is the usual self-hosting bargain: your box, your backups, your pager when the tracker itself goes down.
Common questions
Is self-hosting actually cheaper than Sentry?
Sentry costs $312/year. A VPS from $4.59/mo covers any of the 2 alternatives below, saving roughly $257/year.
Are these Sentry alternatives really free?
The software is open-source and free to run. Your only cost is the server it runs on — often a few dollars a month, less than most SaaS subscriptions.
How much server do I need to self-host one?
Most of these run comfortably on a small VPS — 1–2 GB of RAM is enough for a single-user or small-team setup. Each app's page lists its minimum RAM.
Will I lose features by leaving Sentry?
It depends on the app. The alternatives below cover the core workflow; polish and integrations vary, so check each one's stack and difficulty before you commit.
