About Requirements.txt Analyzer
The Requirements.txt Analyzer is a robust, client-side tool designed to parse, validate, and extract deep insights from your Python dependency files. It helps you identify framework stacks, detect duplicate constraints, flag unpinned packages, and export comprehensive project reports.
How to Use
Real-World Examples
Analyzing a Django Project
Upload a requirements file containing Django, psycopg2, and celery. The tool will instantly detect the Web/API and Database stacks.
django==4.2.0 psycopg2-binary>=2.9.0 celery[redis]~=5.3.0
Project Type: Django Project Stacks: Web/API, Database Pinned: 1, Ranges: 2
Detecting Duplicates and Conflicts
If your file has conflicting constraints, the analyzer will flag them automatically.
requests==2.31.0 requests>=2.0.0
Error: Found 1 package with conflicting version constraints (requests).
Best Practices
- Pin all production dependencies using '==' to ensure deterministic builds across environments.
- Use a virtual environment to test your dependencies before deploying.
- For complex projects, consider using tools like pip-tools or Poetry to manage dependency graphs.
- Regularly audit your dependencies for security vulnerabilities using tools like pip-audit.
Pro Tips
You can click the 'copy' icon next to any package name or version to quickly copy it to your clipboard.
Filter by 'Git' to quickly identify custom repository installations.
Export the Markdown Summary and paste it into your project's README or PR description.
Frequently Asked Questions
Does this tool install packages?
No, this tool statically analyzes the text file and does not interact with your Python environment.
Are Git and Local paths supported?
Yes, the parser natively handles -e editable installs, direct Git URLs (git+https), and local directory paths.
Can I use this offline?
Yes. Once the page is loaded, the entire parser and export engine works completely offline.
Security & Privacy
Security is paramount. The Requirements.txt Analyzer performs 100% of its parsing and generation directly in your browser. Your dependencies and codebase structure are never uploaded to any external server.
