Stagewise is an agentic IDE that integrates a coding agent directly into a browser-based development environment for building and debugging web applications.
The tool addresses the friction of context-switching between browsing, coding, and debugging by combining these activities in one interface. Its coding agent has direct access to the browser tab's console and debugger, allowing it to inspect and interact with running applications in real time. Developers can make temporary test changes within the IDE or connect a persistent codebase for permanent edits. The agent can reverse-engineer website components, style systems, and color palettes by analyzing live pages. Code changes generated by the agent can be viewed and applied directly in external editors through IDE integration.
Stagewise suits developers who want to prototype and debug web applications without leaving the browser, or who want an agent that understands the actual runtime state of their code rather than working from static files alone. The tool supports bringing your own API keys for all major model providers, and allows registration of custom providers including local inference setups, giving flexibility in model choice. This approach differs from traditional agent-based coding tools by emphasizing the browser environment as a first-class development context rather than treating it as separate from code editing.
The project maintains active development with regular updates to both core functionality and documentation. The codebase is written in TypeScript and the team provides localized documentation across multiple languages, indicating sustained effort toward accessibility and international adoption. Community engagement is supported through an active Discord server and social media presence.
