+# dotenv
+
+Although dotenv is reliable, it may not be necessary or may lack certain features.
+
+## Alternatives
+
+### dotenvx
+
+Modern and secure alternative by the same author. It supports encryption, and multi-environment configs.
+
+[Project Page](https://github.com/dotenvx/dotenvx)
+[npm](https://www.npmjs.com/package/@dotenvx/dotenvx)
+
+### Node.js --env-file
+
+Built into Node.js since v20.6.0. Zero dependencies, good for simple use cases.
+
+```bash
+node --env-file=.env index.js
+```
+
+Also supported by [tsx](https://www.npmjs.com/package/tsx), [Bun](https://bun.sh/docs/runtime/env#manually-specifying-env-files), and [Deno](https://docs.deno.com/runtime/reference/env_variables/#.env-file).
