Comparing Code with Diff Mode

Compare two versions of a codebase to identify endpoint changes. Useful for code reviews, security assessments, and understanding feature impacts.

noir -b <NEW_VERSION_PATH> --diff-path <OLD_VERSION_PATH>

Output

Plain Output

The default output marks each change as Added (new endpoints), Removed (deleted ones), or Changed (endpoints whose parameters or methods were modified).

[*] ============== DIFF ==============
[I] Added: / GET
[I] Added: /update POST
[I] Removed: /secret.html GET
[I] Removed: /posts GET

JSON and YAML Output

Use -f json or -f yaml for structured output. Results are grouped into three categories.

{
  "added": [...],
  "removed": [...],
  "changed": [...]
}

Especially useful in CI/CD — feed only the added and changed endpoints into a DAST scanner to focus on modified attack surface.
