APIs change.
Your app
keeps up.

Catch changing contracts. Send the fix to an AI agent. Review a small, source-checked pull request instead of starting from a blank editor.

Stop collecting alerts.
Start moving fixes.

A field becomes optional. A dependency moves. Somewhere in your code, yesterday’s assumption is still running.

Berzz connects the evidence to your code. Its maintenance agent can read the relevant files, prepare a bounded patch, and bring the diff back for your review.

From a broken assumption.
To a reviewable change.

Synthetic Example CRM scenario

Published sample

A name may be null.

{ "name": null }

The contract changed. That alone does not prove your app will fail.

example/customer.ts · line 8

The caller expects a string.

name.trim()

Review the API version and caller before deciding whether to patch.

Evidence you can inspect. An action you can review.

Make the example
break. Then fix it.

No sales call. No connected account.

EXAMPLE CRM / CUSTOMER NAMESynthetic example · no repository scanned

A contract changes

A name can now be missing.
Your code expects a string.

In this example, the customer endpoint begins allowing null. The existing formatter calls trim without checking.

Before

name: string

After

name: string | null

example/customer.ts · line 8
const label = customer.name.trim();

Try the original code, then preview the fix and run the check again.

This check executes only the bundled fixture in your browser. Customer patches still require review and CI verification.

One workspace.
From signal to patch.

Attention
Findings, source evidence, and your maintenance agent. Describe a fix, inspect its patch, and open a pull request when it is ready.
Integrations
The outside services your code relies on, plus what Berzz can and cannot check.
Activity
What scans detected and which fixes were requested. A disappearing finding is never called a verified fix.

Start with the repo
you care about.

Build confidence before you add more.

Useful evidence.
Honest limits.

Berzz reads source and published vendor material. Source matches need review against the API version you use. Unsupported integrations and incomplete reads stay visible.

The agent checks source matches and change size before publication. GitHub CI results stay visible after you open a PR. You review and merge; missing tests are never called a pass.
