The right browser action, beside the page.

Select text, paste data, or use the current page to open the right action without leaving the tab.

Paste anything. We'll figure it out.

Format JSON, inspect JWTs, test regex, pick colors, and act on selected text directly beside the page.

Move from one action to the next.

When one result leads to another, ArcPanel keeps the flow beside the page instead of sending you through tabs and utility sites.

Powerful, but they still hand you back to the browser. ArcPanel works beside the current tab where the actual page context lives.

Utility sites

Open tab, paste, copy, switch back

They make you leave the page. ArcPanel opens the right action in a side panel and keeps your current context intact.
