Frequently Asked Technical Questions (Sentry)

How do you integrate Sentry into an existing application?

Sentry is integrated by adding the platform-specific SDK directly into the application codebase. It requires no dedicated server agents, allowing error collection with just a few lines of initialization.

Does Sentry offer a free tier for small projects?

Yes, Sentry provides a permanent free tier featuring monthly event quotas for errors and performance, designed for individual developers and low-volume projects.

Is it possible to self-host Sentry on own infrastructure?

Yes, Sentry supports self-hosted deployments using containers, though it requires managing additional dependencies such as databases and queue systems in production environments.

What type of data is captured during an error?

When an exception occurs, Sentry collects the stack trace, execution environment info, breadcrumbs of prior actions, and optional context variables while scrubbing sensitive data via filters.
