EnvVarAudit: Unused Environment Variable Detector
Scans your codebase to find and flag environment variables that are defined but never actually used, helping developers clean up config bloat and reduce deployment surface area.
The Problem
Dev teams accumulate environment variables over time—legacy configs, abandoned features, copy-pasted templates—but have no easy way to know which ones are actually referenced in code. This leads to bloated .env files, confusion during onboarding, security risks from unused secrets lingering in systems, and deployment configuration debt.
Target Audience
Full-stack developers and DevOps engineers at startups and mid-size tech companies (50-500 engineers) who manage multiple environments and want to reduce configuration complexity.
Why Now?
Environment variable sprawl is getting worse as teams adopt microservices and multi-environment deployments. GitHub Actions and cloud-native workflows make automation solutions more valuable than ever.
What's Missing
Existing linters (ESLint, etc.) don't specialize in env var auditing across polyglot codebases. Enterprise solutions are overkill and require heavy configuration. There's a gap for a lightweight, opinionated tool.
