About Lasso
Lasso is a visual coding tool for web apps. You select an element on the real rendered interface, tell Lasso in plain language what to change and review the resulting diff to the source code before it is applied. It resolves the selected element to the component file, props and styles behind it, so the context is grounded in your actual code rather than a mockup.
It works with existing setups: for Vite and Next.js projects you run a single command and an overlay attaches to the dev server. Changes can be previewed, files inspected and edits undone, and the work can be merged like any other feature branch. Newer collaboration features include voice and speech-to-text dictation, live cursors and presence, voice conversations inside the tool and a shared clipboard for snippets and URLs.
The site offers documentation, a GitHub link and a pricing section, and it invites visitors to join a waitlist, which suggests access is still limited. A banner announces recently shipped live cursors and voice features.
