.env.example Generator

Why commit a .env.example?

A .env file holds secrets and must never be committed. But new team members, CI and deployment platforms still need to know which variables exist. A .env.example (also called .env.sample or .env.template) lists every key with placeholder values and comments, so anyone can copy it to .env and fill in their own values.

How secrets are detected

• Key names containing SECRET, TOKEN, PASSWORD, PASS, PWD, KEY, PRIVATE, CREDENTIAL, AUTH, SALT, DSN or WEBHOOK.
• Value patterns such as Stripe (sk_live_…), GitHub (ghp_…), AWS (AKIA…), Slack, OpenAI and Anthropic keys, JWTs, PEM private keys and URLs with embedded passwords (postgres://user:pass@…).
• High-entropy strings — long random-looking values are treated as secrets even if the key name looks harmless.

Safe defaults (ports, log levels, NODE_ENV, booleans, localhost URLs) are kept so the example works out of the box. Check the finished file with the .env file validator, and keep .env out of Git with the .gitignore generator.

Tools that pair well with the .env.example Generator

• Dockerfile Generator — Choose your stack and get a production-ready Dockerfile: multi-stage build, cached dependency layer, non-root user, health check and a matching .dockerignore — explained line by line.
• GitHub Actions Workflow Validator — Paste a workflow from .github/workflows and find problems before CI does — invalid triggers, missing runs-on, broken needs, bad expressions, outdated actions and script-injection risks.
• YAML Validator — Paste a Docker Compose file, Kubernetes manifest, GitHub Actions workflow or any YAML to pinpoint errors, catch common pitfalls and get a cleanly formatted version.
• Git Command Generator — Pick a task like “undo the last commit but keep my changes” or “rename a branch on GitHub”, fill in your branch names and get the exact Git commands — each line explained, risky steps flagged.
