Interesting tools

Each week we review 2—3 of the most interesting developer tools. Here's what we featured this week.

Varlock

Enhanced .env files.

What we like

Use decorator comments to create .env config schemas. Allows for validation and type safety. Implement function calls e.g. to load a secret from 1Password. Redacts values in stdout and console methods. Supports different environments. Drop-in replacement for dotenv.

What we don't like

Only has native integrations for Node and Next.js (doesn’t support Turbopack yet), but there is a binary CLI to run and inject values into the environment.

Helix

Terminal text editor.

What we like

Latest release (25.07) includes a file explorer with fuzzy search. LSP integration for auto complete, diagnostics, etc. Tree-sitter integration for syntax highlighting. Built for the terminal with theme support. Works cross platform.

What we don't like

No support for third-party plugins. Some package managers have outdated versions.

Pastoralist

Manage package.json overrides.

What we like

Detects and tracks overrides, resolutions, and patches. Removes overrides and resolutions if they become unneeded. Will notify you if you have unused patches when dependencies are removed. Use it as a post-install script to automatically run the checks.

What we don't like

Would benefit from support for comments to explain the “why” of overrides etc.
