GlitchTip vs Sentry (Community): Open Source Error Monitoring
GlitchTip vs Sentry (Community): Open Source Error Monitoring
Sentry is the gold standard for error tracking. Self-hosted Sentry gives you all its features for free — but it requires 20+ Docker containers and 8+ GB RAM. GlitchTip offers Sentry SDK compatibility in a package that runs on a $5 VPS. Here's the trade-off.
Quick Verdict
Choose self-hosted Sentry for the full platform — performance monitoring, profiling, session replay, cron monitoring, and the most advanced error tracking. Choose GlitchTip for lightweight, resource-efficient error tracking that works with your existing Sentry SDKs.

When to Choose GlitchTip
- Error tracking is your primary need
- Resource-constrained server ($5-20/month VPS)
- Simplest possible deployment
- Already using Sentry SDKs (zero-change migration)
- Don't need replay, profiling, or cron monitoring
- MIT license is preferred
- Small to medium team
- You'd rather spend $10/month than $50-100/month on server resources
When to Choose Self-Hosted Sentry
- Full error tracking platform is needed
- Performance monitoring and profiling
- Session replay for debugging user issues
- Cron job monitoring
- Advanced integrations (Jira, GitHub, PagerDuty)
- AI-enhanced issue grouping
- Large engineering team
- You have the server resources (16+ GB RAM)
- You want the best error tracking available
The Resource Reality
Self-hosted Sentry runs Kafka, ClickHouse, PostgreSQL, Redis, Snuba, and a dozen other services. The minimum viable deployment:
| Resource | GlitchTip | Self-Hosted Sentry |
|---|---|---|
| Containers | 3 (web, worker, postgres) | 20+ |
| RAM | 1-2 GB | 8-16 GB |
| CPU | 1 core | 4+ cores |
| Disk | 5 GB | 50+ GB |
| Monthly VPS cost | $5-10 | $40-100 |
Migration Path
Starting with GlitchTip and moving to Sentry later is easy because GlitchTip uses Sentry SDKs:
- Start with GlitchTip — cheap, simple, handles error tracking
- When you need more — deploy self-hosted Sentry
- Change the DSN — same SDKs, same code, just point to Sentry
- No application changes — the migration is infrastructure-only
The Bottom Line
GlitchTip gives you 80% of Sentry's value at 10% of the resource cost. For most projects — especially early-stage, small teams, and resource-constrained environments — that's the better trade-off.
Self-hosted Sentry is the full platform. If your team needs replay, profiling, cron monitoring, and advanced integrations, the resource investment is worth it.
Start with GlitchTip. Graduate to Sentry when the features justify the infrastructure.
