Meet Hud: The world's first production-aware dev platform

Using Hud, you can see how your code behaves in production without leaving your IDE.

Once Hud is installed in your service, function-level metrics are automatically collected across the entire code base, including performance, exceptions, and cost - so you can identify and solve trends and degradations before they break production.

Hud PR Comparison: Your PR Guardian

We’ve got your back to ensure your changes don’t break production.

The Hud PR Comparisons feature empowers developers to detect performance degradations early in the development process.

How It Works

Hud compares the performance of new code introduced in a Pull Request (PR) against the existing code in the main branch, so you can address potential issues before they reach production.

Once the Hud GitHub App is installed in your repository, Hud will automatically add a comment to your PR whenever a performance degradation is detected during the PR’s tests.

Key Capabilities

🕵️‍♂️ Impact Analysis: Understand how new code in a PR affects endpoint metrics within your service.
📊 Metric Comparison: Compare critical metrics like P90 duration and error rates between the PR and the main branch.
⚠️ Proactive Alerts: Receive detailed PR comments highlighting performance degradations detected during testing.

Thresholds

Hud will issue a warning about endpoint degradation if the following thresholds are met during a single test job:

Minimum Degradation Rate: 100%
Minimum Number of Invocations: 200
Minimum P90 Duration: 200ms

These thresholds ensure that warnings are raised only for significant and impactful degradations. Let us know if you'd like further refinements!

This feature is available for a limited early customers. If you wish to enable this feature, please reach out to a Hud team member or contact [email protected].
