What you can use it for
Check Python files and folders for common mistakes, with local fixes and CI exit codes.
- Scan a Python project without a paid workspace-checking plan.
- Detect unused imports and undefined names; apply supported mechanical fixes.
Workflow coverage and comparison notes
Replace Python file/folder linting and a configured CI pass/fail check. Not Iris full scoring, multi-language analysis, secrets, dependency auditing or managed cloud history. MIT software; own hardware and any CI hosting are extra, no paid API needed.
Before you switch
Python only. Replaces project linting and configured command-line gates, not all Iris features. No Iris health score, multi-language workspace graph, complete secret scanner, dependency CVE audit, SBOM, cloud audit history or AI review. Configure rules and CI yourself; review fixes. Own hardware/electricity and any hosted CI runner can cost extra. No paid model API is required.
