StructFlow

About

StructFlow is a developer's side panel for JSON and code. Paste anything, format it, explore it, snapshot it, and save it — without leaving your browser and without sending your data anywhere.

Everything runs locally. No account, no sign-in, no servers. Your snippets and notes are stored privately in your browser.

WHAT YOU CAN DO
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Format multiple languages — Markdown, Plain Text, TypeScript, JavaScript, JSON, HTML, CSS, and SQL — with clean, VS Code-style defaults. Tune tab width, quotes, semicolons, print width, wrapping, and alphabetical key sorting.

• Explore JSON visually — an interactive, collapsible tree with search across keys and values, copy-path and copy-value, and color-coded types. Prefer text? Switch to a syntax-highlighted view with line numbers.

• Read JSON anywhere — open a raw .json page or API response and StructFlow turns it into a clean, themeable viewer with Formatted, Tree, and Raw modes plus search — right on the page.

• Snapshot your code — turn any formatted output into a polished, shareable PNG. A windowed "code card" with traffic lights, a filename, your chosen syntax theme, backdrop colors, padding, and line numbers. Copy to clipboard or download.

• Take notes — Markdown is the default and comes with a live rendered preview, and Plain Text is a no-reformat scratchpad. Use the side panel as a quick, always-available notebook.

• Build a personal library — save anything you format into projects and folders (rename, recolor, and add items right from a folder), search across everything, and re-open, copy, export, or delete in a click. Export all or selected folders as a single .zip backup whenever you want.

• Make it yours — pick from editor/JSON syntax themes (VS Code, GitHub, Monokai, Dracula, Nord, Solarized, and more) and switch the whole panel between light and dark.

• Open it fast — use the toolbar icon, the right-click menu, or the keyboard shortcut (Alt+Shift+S / Command+Shift+S on macOS).

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PRIVACY-FIRST
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

StructFlow works fully offline. It does not collect, transmit, or sell any data. All formatting happens on your device, and your saved snippets and notes never leave your browser.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
PERFECT FOR
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

• Inspecting and cleaning up API responses while you work
• Sharing good-looking code screenshots in docs, issues, and social posts
• Keeping quick notes and reusable snippets next to whatever you're doing
• Tidying JSON, SQL, and code without pasting it into a random website

Open the side panel, paste, and go.
