Your dev server, beside the code.
Open an in-app browser pane on the canvas and watch your app render as your agents build it. Preview panes are scoped to your local dev server, right next to the terminals.
Preview without leaving CodeGrid
A pane for localhost
Open a live in-app browser for your dev server and place it anywhere on the canvas.
Type a URL
Point a preview pane at the local address your server is running on.
Auto-detected URLs
CodeGrid watches your terminal output for localhost URLs and offers to open them in a preview pane with one click.
No toast spam
Each detected URL is offered once, then held back for a few minutes so recurring output doesn't nag you.
Scoped to your dev server
Preview panes are intentionally for localhost dev servers, kept right beside the code that produces them.
External links open out
Non-localhost links get a quick “open externally” affordance instead, in your real browser.
Build and preview, side by side.
See the change the moment your agent makes it.
