Edit your live UI in your design system, hand off the diff
Skisso is a free Chrome extension for designers and developers who build with AI coding agents. Point at any element on your live product and edit it in your own design system: your tokens, your components, a shadcn/ui kit that matches your styles. Then hand your agent only the exact change, as a small diff or over MCP. No more describing pixels in prose or pasting the whole page: about 380 tokens instead of 25,700 in our test. Runs locally, no account.
Skisso launched on Product Hunt on 2026-10-16 and has 61 upvotes and 6 comments so far.
