Generative AI coding assistant for building, operating, and transforming software
Discover top open-source software, updated regularly with real-world adoption signals.

AI-powered frontend coding agent that edits production web apps
stagewise lets developers describe UI changes in natural language, click target elements, and automatically updates the local codebase across any framework, streamlining frontend development without manual path hunting.

stagewise is an AI‑driven frontend coding assistant that lives in your browser. By describing the UI change you need and clicking the target element, the agent generates the corresponding TypeScript/JavaScript, HTML and CSS updates directly in your local development folder. It works with any framework—React, Vue, Angular, Svelte, or plain HTML—because it relies on real‑time browser context rather than static file heuristics.
Start your application in development mode, run npx stagewise@latest in the project root, and follow the CLI guide to link your account. Once active, you can issue natural‑language commands, select DOM nodes, and let stagewise apply the changes. The core agent can be swapped for compatible alternatives (Cursor, GitHub Copilot, etc.) via the open agent interface, and additional functionality can be added through a plugin system. Because the tool runs locally, no external services touch your code, keeping the workflow secure and compliant with the AGPL‑3.0 license.
When teams consider stagewise, these hosted platforms usually appear on the same shortlist.

Update button label across multiple pages
All instances of the button text are changed consistently with a single natural‑language command.
Refactor component styling
CSS classes are updated and related JSX/TSX files are adjusted automatically.
Add a new input field to an existing form
HTML markup, validation logic, and state handling are generated and inserted in the correct files.
Migrate from one UI library to another
Component imports and usage patterns are replaced across the codebase based on the specified target library.
It works with any frontend framework because it uses live browser context, including React, Vue, Angular, Svelte, and plain HTML/CSS.
Run `npx stagewise@latest` (or `pnpm dlx stagewise@latest`) in the root of a development‑mode web app and follow the CLI prompts.
Yes, it writes changes to your local files after you confirm the generated edits.
Yes, the open agent interface lets you plug in compatible agents such as Cursor, GitHub Copilot, Windsurf, and others.
stagewise is released under AGPL‑3.0; commercial projects must comply with its terms or contact the maintainers for alternative licensing.
