## Understand the blast radius.

### Automatic change detection

We continuously poll the OpenAPI specs of your dependencies. When a breaking change is released, Repairo catches the diff instantly.

### Impact mapping across the codebase

Repairo scans your entire codebase to find every affected call site, type definition, and status check. We understand TypeScript at a deep level.

### Safe, reviewable PRs

Zero AI hallucinations. Repairo generates a clean, deterministic patch based on OpenAPI specification changes and opens a review-ready Pull Request.

### Zero configuration

Connect your GitHub account and point Repairo at an OpenAPI URL. We handle the rest.

## How Repairo works.

### Detect drift

We diff the OpenAPI specs of your dependencies every time they release. When a breaking change is found, we catch it instantly.

### Map impact

Repairo scans your codebase. We find exactly where the API was called, what types changed, and trace the full impact.

### Apply patch

We generate the necessary code changes and open a clean, reviewable Pull Request.

### Pull Request

Providers announce, Repairo patches.

## Get started locally offline.

Run our CLI locally against your codebase—no cloud backend or third-party AI keys required.

`tsc --noEmit`

)## Enterprise-level safety, on your terms.

Guardrails on every action. Your code stays private, always.

### Generic Approach

- Full repository clone
- Code stored indefinitely
- No audit trail
- Broad OAuth scopes
- Black-box AI decisions

### Repairo

- Read-only, scoped to affected files
- Zero data retention
- Full audit log on every action
- Minimal GitHub permissions
- Deterministic, reviewable patches

#### Zero Data Retention

Your code is processed in temporary memory and wiped immediately.

#### Minimal Permissions

We request only the GitHub scopes needed. Nothing more.

#### Full Audit Trail

Every detection, patch, and PR is logged and traceable.

#### Compliance Ready

## Everything you need to know.

Never. We follow a strict Zero-Retention policy. Your code is processed in secure temporary memory only while creating the fix, and is completely wiped immediately after. Your code always remains 100% private.

#### No. Repairo follows a strict zero-retention policy.

- Your private code is never stored.
- It is never retained after processing.
- It is never used to train AI models.
- We only analyze the code required to generate deterministic patches.
- Your repository remains under your control, at all times.

This end-to-end zero-retention approach gives security teams complete peace of mind and meets the highest standards of enterprise security and compliance.
