Limno

Tweak any site visually, then hand the changes to your coding agent or engineer as a precise fix request.

Limno is a visual editor for the websites you review. Open any page, adjust it the way you would in a design tool, and turn your changes into a precise fix request that a coding agent or an engineer can build straight away. No more screenshots covered in arrows or "make it a bit bigger". Limno records exactly what you changed, on which element, in which state, using the site's own design tokens. WHAT YOU CAN DO • Select anything on the page and adjust spacing, colour, radius, borders, shadows, opacity and text. • Pick values from the site's own design tokens (colours, spacing, radius), read live from the page. • Edit interaction states: hover, focus, pressed and disabled. • Choose the scope: just this element, or every matching instance. • Leave comments pinned to the exact element you mean. • Check your changes at desktop, tablet and phone widths. • Compare before and after at any time. HAND IT OFF • Copy for agent: a structured prompt for Claude Code, Cursor, Codex or any coding agent. • Export: one HTML file with before and after screenshots, the prompt and the structured change set, ready to attach to a ticket or send to an engineer. • Working locally with the Limno Vite plugin? The extension uses it automatically, and agents connected through Limno's MCP server pick up your changes and report progress back. WORKS ON REAL SITES • Test, staging and production pages, not just local development. • Nothing changes on the live site. Your edits are a preview in your browser until someone builds them. • Sites with strict security headers work too. PRIVATE BY DESIGN • Limno does nothing until you click its button, and only in that tab. • Your drafts stay in your browser. Nothing is sent to us or anyone else, and there is no account, tracking or analytics. HOW TO USE 1. Open the page you're reviewing. 2. Click the Limno button in the toolbar (or press Alt+Shift+E). 3. Select an element, make your changes, add comments. 4. Copy the prompt for your agent, or export a fix request.
