About this tool
Dev Environment Parity Checker
The Dev Environment Parity Checker assesses local vs production environment parity across database, service topology, and configuration dimensions.
• Audit local dev environment parity before onboarding new engineers
• Identify the biggest parity gaps before a 'works on my machine' debugging session
• Assess environment setup quality during a DX audit
• Prioritize environment improvements for a DevEx sprint

FAQ
What does this tool tell you?
The Dev Environment Parity Checker assesses local vs production environment parity across database, service topology, and configuration dimensions.
What affects the result most?
Environment parity: dev ≈ staging ≈ production — differences are bugs waiting to happen. Common parity failures: local uses SQLite, prod uses Postgres; local HTTP, prod HTTPS; different env vars. Docker Compose for local: replicates production service topology — eliminates most parity issues.
How should I use the result?
Treat the tool's output as a first-pass check, not a proof of correctness. A clean pass means no issues in the patterns this tool recognizes; a failure points to a specific problem you can investigate in your source. The underlying spec is the authoritative source for edge cases.
