Stagewise is an AI-powered developer browser that puts a coding agent right inside your browsing experience. Point at any element on your running web app, describe what you want in plain language, and the agent makes the code changes for you. It works with React, Vue, Angular, Svelte, Next.js, and more. You can use it standalone or bridge it to IDE agents like Cursor, Copilot, and Windsurf. Backed by Y Combinator and used by teams at companies like Adobe, Amazon, and Microsoft.

• Visual Element Selection: Click on any UI element in your running app to give the AI agent precise context about what you want to change, including DOM structure, screenshots, and metadata.
• Built-In Coding Agent: Chat with an AI assistant that can read, write, and modify files in your workspace directly from the browser, with full console and debugger access.
• Framework Agnostic: Works with React, Vue, Angular, Svelte, Next.js, Nuxt.js, and CSS frameworks like Tailwind, Bootstrap, MUI, and ShadCN.
• Inline Diff Review: Accept, reject, or partially accept code changes with full inline diffs before they hit your codebase.
• Dual Operation Modes: Use the built-in Stagewise agent or connect external AI coding agents via bridge mode (Cursor, Copilot, Windsurf, etc.).
• Reverse Engineering: Inspect and reuse components, style systems, and color palettes from any website you visit.
• BYOK Support: Bring Your Own API Key for Anthropic, OpenAI, Google, and other providers for unlimited access.
• Plugin System: Extend functionality with framework-specific plugins for deeper React, Vue, and Angular integration, or build custom plugins.

• Zero Setup Required: Run npx stagewise and you're ready to go. No dependencies to install in your project, no configuration files to manage.
• Great for Non-Technical Team Members: Product managers, designers, and non-technical founders can make frontend changes without writing code, using plain language descriptions.
• Works with Existing Codebases: Unlike tools that only work with new projects, Stagewise is built specifically for production-grade, brownfield codebases.
• Eliminates Context Switching: Browse your app and make code changes in the same window instead of jumping between browser, IDE, and chat tools.

• Free Tier Is Limited: The free plan includes limited usage quotas, which may feel restrictive during active development sessions.
• Primarily Frontend Focused: The tool is designed for UI and frontend changes. It has limited visibility into server-side logic and backend code.
• Team Costs Can Scale: aid plans are priced per user, so costs increase as teams grow.
• OAuth Login Required in Standalone Mode: The standalone agent mode requires OAuth authentication, which may not suit every developer's workflow preferences.

• Rapid UI Iteration: Select a button on your live app and prompt "make this a secondary button with a gray outline." The agent generates the code change instantly, letting you iterate on component styles without digging through source files.
• Design System Awareness: Modify UI components using existing code context to maintain consistency with design patterns and tokens.
• Non-Technical Stakeholder Collaboration: Product managers and designers can point at specific UI elements and describe changes in plain language. The agent translates those instructions into actual code changes that developers can review and approve.
• Legacy Codebase Maintenance: Working on brownfield projects with complex CSS and component relationships becomes simpler. Stagewise reverse-engineers existing styles and helps you make targeted modifications without breaking adjacent components.
• Prototype to Production: Go from a rough idea to a working frontend by describing what you want in natural language. Review inline diffs, accept changes incrementally, and ship when the result matches your vision.
