Sentry

Sentry is an error tracking and application monitoring platform built specifically for developers. It automatically captures, organizes, and prioritizes errors and performance issues across your entire stack—from frontend JavaScript to backend APIs—providing detailed context, stack traces, and breadcrumbs that make debugging significantly faster. With support for 100+ platforms and frameworks, Sentry integrates directly into your development workflow.

Best for: Development teams that want to catch and fix errors before users report them. Particularly valuable for web and mobile apps where client-side errors can be difficult to reproduce. Teams appreciate Sentry's developer-friendly interface, detailed stack traces with source maps, and integration with issue trackers like Jira, GitHub, and Linear.

Common Questions

How does Sentry track errors?
Sentry SDKs integrate into your application code and automatically capture unhandled exceptions, promise rejections, and crashes. Each error includes a full stack trace, user context, device information, breadcrumbs (events leading up to the error), and environment details. Source maps are automatically applied for minified JavaScript. Performance monitoring tracks slow transactions and database queries with distributed tracing.

What platforms does Sentry support?
Sentry supports JavaScript, React, Vue, Angular, Python, Django, Flask, Ruby, Rails, PHP, Java, Kotlin, .NET, C#, Go, Rust, Swift, Objective-C, React Native, Flutter, Unity, and 80+ other platforms. Both frontend and backend are supported. Mobile crash reporting works for iOS and Android with automatic symbolication.

How does Sentry pricing work?
Sentry charges based on monthly events (errors) and transactions (performance monitoring). The Developer tier is free up to 5,000 errors and 10,000 transactions per month with 1 user. Team tier is $26/month for 50,000 errors and unlimited users. Business tier starts at $80/month for 100,000 errors with advanced features. Enterprise pricing is custom for high-volume applications.

Does Sentry work with my issue tracker?
Yes, Sentry integrates bi-directionally with Jira, GitHub Issues, GitLab Issues, Azure DevOps, Linear, Shortcut, Asana, and many others. Errors can auto-create tickets with full context, or you can link existing tickets. Status syncs both ways—resolving the Sentry issue when the ticket closes.

Pricing & Plans

• Developer: Free, 5,000 errors + 10,000 transactions/month, 1 user, 30-day retention
• Team: $26/month, 50,000 errors + 100,000 transactions/month, unlimited users
• Business: $80/month, 100,000 errors + 500,000 transactions/month, adds SAML, priority support
• Enterprise: Custom pricing for millions of events, dedicated support, SLAs

Additional errors: $0.000045/error beyond plan limits. Additional transactions: $0.000225/transaction beyond plan limits.

Limitations

• Event volume costs scale quickly: Applications with high error rates or performance monitoring on high-traffic endpoints can consume events rapidly. Requires careful sampling configuration.
• Source map requirement for minified code: JavaScript errors are difficult to debug without proper source map uploads during deployment. This adds a build step but is necessary for readable stack traces.
• Self-hosted version lags features: Open-source self-hosted Sentry typically runs 6-12 months behind the SaaS version in feature parity.

Getting Started

1. Sign up for free at sentry.io
2. Create a new project and select your platform (React, Python, etc.)
3. Install the Sentry SDK via npm, pip, gem, or your package manager
4. Initialize Sentry in your application code with your DSN (Data Source Name)
5. Optionally upload source maps during build for readable JavaScript stack traces
6. Deploy and errors will begin appearing in your Sentry dashboard automatically

The free tier is sufficient for most small projects. Upgrade when you need more events, additional users, or advanced features like custom retention.
