The coding agent that works in its own browser environment
stagewise is an open-source coding agent that can actually see your app. It works in its own browser environment, reads the DOM and console, and edits the code behind what it’s looking at. Use any model, bring your own key, and keep full control.
stagewise is open-source and extensible, allowing developers to customize the IDE, integrate with favorite tools, and contribute to the codebase. The GitHub repository provides full transparency and community-driven development.
stagewise supports all major model providers (OpenAI, Anthropic, Google Gemini, DeepSeek, Qwen, and others) through a unified interface. Users can connect existing coding subscriptions or use their own models, including locally-run models, providing flexibility across providers.
stagewise enables users to create and orchestrate multiple coding agents in parallel, each handling independent features or bug fixes. The Smart Approvals feature provides intelligent middle ground between full automation and manual approval, allowing routine commands to run automatically while blocking destructive or system-level operations.
stagewise provides built-in app preview capabilities and git workflow integration, allowing developers to see changes in real-time and manage version control operations directly within the agentic IDE.
stagewise's agent maximizes cache-hit rates (87.6% average) and dynamically controls context window usage, enabling long-running tasks at significantly lower cost compared to standard agent implementations.
