CodeFlask
A tiny, elegant code editor for the browser with syntax highlighting. Write and edit code in a clean, minimal interface.
About CodeFlask
Type a few lines of JavaScript, Python, or any common language into the editor and watch syntax highlighting kick in immediately — no setup, no account, no configuration required. CodeFlask is a stripped-down browser-based code editor built for moments when you need a clean surface to write or tweak code without opening a full IDE. It's genuinely minimal, which is the point.
It fits naturally into the developer tools corner of the catalog, sitting alongside utilities built for quick, focused tasks. If you paste a snippet to test logic, sketch out a function, or share readable code with a colleague, the lightweight interface keeps the focus on the text rather than the tooling around it. For processing or transforming what you write next, CyberChef pairs well for encoding, hashing, and manipulation tasks.
CodeFlask works best on a desktop or laptop where a real keyboard is within reach — the editing experience on touchscreens is functional but limited, so plan accordingly.
