Test APIs without leaving the editor

Fire requests with headers, query params, JSON, GraphQL and form bodies. Import from cURL, copy back out, and keep a request history — response viewer with status, timing and size built in.

// DIFF EDITOR

See exactly what changed

A full side-by-side diff view powered by the same Monaco engine — inline or split, with syntax highlighting on both sides. Perfect for reviewing edits before you export or commit.

Everything is a keystroke away

Hit ⌘⇧P for the command palette or ⌘P to jump to any file. Format, toggle word-wrap, switch language, enter Zen mode, save workspaces — all searchable, all rebindable.

// REGEX PLAYGROUND

Build patterns with live matches

Write a pattern, toggle flags, and watch matches highlight in your sample text in real time — with capture groups broken out below. No more guessing whether that lookahead works.

Batteries included

The niceties you expect from a real IDE, ready the moment the page loads.

Multi-file workspace

Drag-to-reorder tabs, a tree explorer with folders, quick-open and search across every tab.

Themes & snippets

Import any VS Code theme JSON, manage custom snippets, and rebind every keyboard shortcut.

Run & preview

Execute code, render live HTML previews and view CSV files as sortable tables inline.

Share & export

Compress a file into a shareable URL, or export to standalone HTML and print-ready PDF.

Import & workspaces

Open files from disk, import ZIP archives, save whole workspaces and reload them later.

Problems & diagnostics

Live error and warning counts in the activity bar, with a dedicated problems panel per file.

Open a repo. Start editing.
That's the whole setup.
