Inside each project

Find what needs attention. Choose what happens next.

The local scan checks known API key patterns and setup gaps. Results are separated into supported Fixes, manual review, environment files, and optional repository checks so each next step stays clear.

Fixes
Review supported local changes and apply them individually.
Review
Handle findings Halden cannot fix for you, including key rotation and external follow-up.
Environment Variables
Review and edit detected environment files locally.
Protection
Review pre-commit protection, local Git history, GitHub Secret Scanning, and dependency checks when needed.

FAQ

Questions before you start.

Does Halden upload my source code or API keys?

No. The normal project scan runs on your device and does not upload source files, environment values, or detected API keys. Account, license, and update requests are separate. Optional GitHub checks send the repository owner and name. Dependency audits run through your local package manager and may contact its configured package registry. Read how Halden handles project files.

Does Halden change files during a scan?

No. A scan does not change project files. Halden writes only after you choose an individual Fix, save an environment file, or install or remove pre-commit protection.

Can Halden fix every finding?

No. Unsupported or ambiguous findings remain in Review. Key rotation, history cleanup, and provider-side actions remain manual.

Which platforms are supported?

Halden is available for Apple silicon Macs running macOS 11 or later and Windows x64. Linux is not currently distributed.
