Env File Generator
Generate .env files for Next.js, Django, Laravel, Express, and more with auto-generated secrets and multiple export formats.
What Is a .env File?
A .env file stores environment variables as KEY=VALUE pairs. Frameworks load these values at runtime so secrets and configuration stay out of source code.
Why Use an Env Generator?
Manual setup is error-prone. This tool provides starter templates for popular stacks, generates secure secrets in the browser, and exports to multiple formats from one configuration.
Supported Secret Tokens
auto:base64:32for URL-safe secret tokensauto:hex:32for hexadecimal secretsauto:uuidfor UUID v4 valuesauto:password:20for readable passwordsauto:int:3000-3999for random integers in a range
Output Formats
Generate standard .env, redacted .env.example, docker-compose environment blocks, bash export scripts, JSON, or YAML.
Related tools: try the Django Secret Key Generator for standalone secret generation and the JSON Serialize Online tool for config serialization workflows.
Frequently Asked Questions
Should I commit .env to git?
No. Add .env to .gitignore and commit .env.example instead. If secrets were committed, rotate them immediately.
How does .env.example redaction work?
Keys that look sensitive, such as names containing SECRET, PASSWORD, TOKEN, API_KEY, or AUTH, are output with empty values so teammates know which variables are required.
Are generated secrets cryptographically secure?
Yes. Secret tokens are generated in your browser using crypto.getRandomValues, which is suitable for development and local environment setup.
Can I combine multiple framework templates?
Yes. Select multiple templates to merge their variables. Custom KEY=VALUE lines override template defaults when keys collide.
Which format should I use for Docker?
Use the docker-compose YAML output to paste an environment: block directly into your service definition with quoted values.
