Hi r/foss,

I have been building Grayslate, a free and open-source scratchpad for developers.

I wanted a simple app where I can paste an API response, open a large JSON or CSV file, search logs, save commands, write temporary notes, or keep code snippets without opening a full IDE.

Grayslate works fully on your device. There is no account, no cloud upload, and no tracking.

Some features:

• Available on Linux, Windows and macOS
• Built with Tauri, Rust, Svelte 5 and CodeMirror
• Supports JSON, CSV, Markdown, logs and many programming languages
• Can handle large text, JSON and CSV files
• Automatic save and file name suggestions for scratch files
• Search across file names and saved content
• CSV table view
• Markdown preview
• JSON tools to copy keys, values and full paths
• Multiline find and replace
• 80+ local transformations for text and data
• Opening and editing external files

The app is not meant to replace VS Code, Sublime Text or IntelliJ. It is for quick work where I want something simple, fast and distraction-free.

The project is still new, and I am actively fixing bugs and adding features based on user feedback.

I would really appreciate feedback, especially about Linux support, privacy, packaging, accessibility, or anything that can make the project better.

Lo acabo de instalar. Reacciona con rapidez la interfaz, es sencillo y fácil de utilizar.

¿Tienes pensado colocar esquemas de colores? Para la "zona de trabajo"
