Stagewise

The demos are good: click an element, prompt a change, watch it update live. But you'll run into unfinished work on edge cases, and the tooling still needs polish. For teams tired of pasting UI trees into chat, Stagewise brings the visual feedback loop back to your local codebase.

Stagewise is a browser-based coding agent that runs inside your dev environment, giving the AI visual access to your actual running app. Click HTML elements, describe what you want, and it edits your source code directly—no context-switching to a separate tool. It works with all major frameworks, uses token caching to hold down costs, and doesn't bloat your production bundle. Early adopters on large React codebases report it outperforms cursor-based editors at gathering just enough context to make good changes. But the tool is visibly immature: users praise the team's responsiveness to bugs while noting the product needs more polish, and feedback surfaces that visual-based debugging works well while other workflows still stumble. You're adopting a two-person team's young open-source tool, not a mature platform.

*Pick this if you iterate on frontend design a lot and want to see changes live in your real codebase. If your workflow leans on text-based prompts or backend logic, wait six months for the rough edges to smooth out.*
