Sentry's event quota is the usual reason to look: one noisy release can consume a month of errors.
Compare on how events are sampled and whether self-hosting is realistic for your team.
Side by side
| Tool | Pricing | Best for | Platforms |
|---|---|---|---|
| Grafana | Freemium | An SRE team that needs one dashboard over metrics already sitting in Prometheus and a managed database. | Web, Docker |
| PostHog | Freemium | A seed-stage product team that wants analytics, replay, and flags behind one SDK instead of three vendors. | Web, Self-hosted |
The options, and what each one costs you
- Better if
- An SRE team that needs one dashboard over metrics already sitting in Prometheus and a managed database.
- You give up
- It visualises data, it does not store it, so you still need a time-series database, and configuration for complex alerting is verbose.
- Better if
- A seed-stage product team that wants analytics, replay, and flags behind one SDK instead of three vendors.
- You give up
- Instrumenting it properly is a real project, event volume pricing gets steep as you grow, and self-hosting is a serious operational commitment rather than a checkbox.
Frequently asked
What is the best alternative to Sentry?
It depends on what you are leaving for. Compare on how events are sampled and whether self-hosting is realistic for your team. Our closest match on features and price is Grafana.
Is there a free alternative to Sentry?
Grafana is free to start. PostHog is free to start.
How much does switching from Sentry cost?
Migration is usually the expensive part, not the licence: exports rarely preserve permissions, history or automations. Budget a day per active workspace for anything with a database in it.
