StructFlow

A side-panel workspace to format code, take notes, and explore JSON. Private and offline.

StructFlow is a code and notes workspace that lives in your browser's side panel. Beautify and highlight your code, write Markdown notes, and work with JSON, then save everything to a searchable library you organize with folders and tags. It also turns raw JSON pages into a clean, readable viewer. Everything runs locally in your browser, with no account and no servers. • Format and highlight code on one clean editing surface, with support for many popular languages. • Explore JSON as a searchable, collapsible tree, and copy any value or its path. • Open raw data pages in a clean, readable viewer, right where you are. • Organize a personal library with folders, tags, and full-text search, plus import and export. • Turn code into a shareable image, and write notes with a live preview. Private and offline. Open the side panel, paste, and go.
