Devdock Tools

Developer tools for the page you are on: read raw JSON as a collapsible tree and capture the full page as an image.

Devdock Tools gives you a better view of the page you are already looking at. Open a URL that returns raw JSON and it is rendered as a collapsible tree instead of a wall of unwrapped text — syntax coloured, expandable node by node, with the original response one click away. A stats panel reports size, key count, item count and nesting depth. Copy the JSON back out formatted, minified, or exactly as the server sent it. Capture the page as an image from the toolbar button or the right-click menu. Full-page capture renders everything, not just the part you can see, including content further down that has not been scrolled to yet. You can also capture a single scrolling region — a modal or a panel with its own scrollbar — in full, which normal screenshots cut off at the edge of the box. Save as PNG, JPG or PDF, or copy straight to the clipboard. Everything runs locally. There is no account, no server and no analytics, and nothing you capture or view leaves your browser. Note: full-page capture uses Chrome's DevTools Protocol to render the whole page in one pass, so Chrome shows a "started debugging this browser" notice while a capture is running. That is expected and it disappears when the capture finishes.
