Making .env Management Simple
.env Tools is a free collection of utilities designed to help developers work with environment variable files more efficiently and securely.
Our Mission
We believe that every developer deserves access to quality tools without barriers. Environment configuration might seem simple, but small mistakes can lead to hours of debugging or, worse, security vulnerabilities in production.
Our mission is to provide free, privacy-respecting tools that help developers catch configuration errors early, follow best practices, and ship with confidence.
Privacy First
We understand that .env files contain sensitive information - API keys, database credentials, and secrets that could compromise your entire infrastructure if exposed.
That's why all our tools process data entirely in your browser. Nothing is ever sent to our servers. We don't track what you paste, we don't store your files, and we never will. Your secrets stay yours.
What We Offer
.env Viewer
Parse and validate your .env files. Detect duplicates, syntax errors, and potential issues before they cause problems.
.env Merger
Combine multiple .env files with intelligent conflict resolution. Perfect for migrations and team onboarding.
.env Generator
Quickly generate .env templates with common variables for databases, auth, APIs, and more.
Why We Built This
As developers, we've all been there: spending hours debugging an issue only to discover it was a duplicate key in an .env file, or accidentally committing credentials to a public repository. These are frustrating, sometimes costly mistakes that are entirely preventable.
We searched for good .env file tools but found that most were either:
- Server-based, requiring you to upload sensitive credentials to someone else's infrastructure
- Part of expensive enterprise tools that were overkill for simple validation needs
- Command-line only, requiring installation and setup
- Abandoned projects with outdated dependencies
So we built .env Tools - a collection of browser-based utilities that work instantly, require no installation, and never see your data. We made it free because we believe good developer tools should be accessible to everyone, whether you're a solo indie hacker or part of a large enterprise team.
