Performance Budget Enforcer
Lighthouse CI after every deploy. Regressions visible before users report them.
What you get
Scores after every deploy
Performance, Accessibility, Best Practices, and SEO scores land in your deploy dashboard automatically. No separate Lighthouse setup, no CI configuration file.
Regression detection
ZipLoom compares the score from the new deploy to the previous deploy's score. A drop of more than your configured threshold flags the deploy for review before traffic reaches 100%.
No testing environment gap
Lighthouse runs against the actual deployed URL on the target platform — not a local dev server or a preview build. The score reflects what users actually experience.
How it works
- 1
After a deploy completes, ZipLoom fetches the deployed URL.
- 2
Lighthouse CI runs against the live URL from a consistent network location.
- 3
Scores are parsed and stored against the deploy record.
- 4
If any score drops below your configured budget, the deploy is flagged.
- 5
Scores are visible in the dashboard on the deploy detail page.
What this check inspects
Core Web Vitals on the deployed app — largest contentful paint, interaction latency, and layout shift.
Bundle size against the budget you set, so a regression is a build signal rather than a user complaint.
Render-blocking resources and unoptimized images, the two things that most often make an AI-generated page slow.
Whether a release made performance worse than the one before it.
What it means when this fails
Performance failures don't error — they just cost you users and search ranking quietly. A budget turns 'the site feels slower' into a number attached to the specific release that changed it.
Questions
- Is this a hard gate?
- It's a budget you set. You choose whether a breach warns or blocks.
- Does it slow the deploy?
- Checks run against the deployed release; they don't sit in the critical path of shipping.
- Why does this belong with a security product?
- Because both answer the same question — is this release fit to be in front of users — and both are things AI-generated code routinely gets wrong.
