# Stay Aligned with Upstream While Keeping Your Customizations Intact

*Link your forked repo. Our AI monitors upstream, merges changes, fixes conflicts, updates contracts, and ensures the build stays green.*

Connect your forked GitHub repo. ForkSync uses AI to sync upstream changes, resolve conflicts, detect contract drifts, repair failing builds, and open pull requests automatically.

## How ForkSync Works

### 1. Connect Your Fork
Enter the fork URL or select from your GitHub account. ForkSync validates access and identifies the upstream base repository.

### 2. AI Analyzes Upstream Changes
The system fetches new commits from upstream, parses code, detects API contract changes, and maps them against your custom modifications.

### 3. Smart Conflict Resolution & Drift Handling
AI proposes merge strategies, preserves your patches, resolves file‑level conflicts, and flags contract drifts with suggested fixes.

### 4. Build Repair & Validation
Runs your CI pipeline, auto‑fixes broken imports or version mismatches, and ensures the repository builds successfully before merging.

### 5. Automatic Pull Request Creation
After a successful merge and build, ForkSync opens a PR in your fork with a detailed summary of changes, conflict resolutions, and test results.

## What Can ForkSync Do for Your Project?

From simple upstream updates to complex contract migrations, ForkSync handles it all with AI precision.

## FAQ

### Which version control systems are supported?
Currently GitHub repositories (public, private, forks, and linked‑source). Support for GitLab and Bitbucket is planned.

### What if upstream changes conflict with my custom code?
AI evaluates the diff, suggests the optimal merge strategy, and can automatically apply resolutions or present a guided manual option.

### What is contract drift and how does ForkSync handle it?
Contract drift occurs when upstream API signatures change. ForkSync flags affected calls, suggests code updates, and can auto‑apply safe refactors.

### Can ForkSync fix broken builds after a sync?
Yes. It runs your CI, identifies failing steps, applies dependency version bumps, import fixes, or adds missing files, then re‑validates before merging.

### Do you store my repository data?
All analysis runs in-memory during your session. No source code is persisted beyond the sync operation, and tokens are never stored.
