An IDE where the coding agent reads your browser console

What it does

stagewise is an IDE with a built-in coding agent. It lets you browse websites, make temporary test edits, or connect a codebase for permanent changes without switching tools. The agent can read your active tab’s console and debugger, and you can reverse-engineer components, styles, and color palettes from any site. It also integrates with external editors so you can view and apply changes back in your preferred IDE.

The interesting bit

The agent isn’t just chatting beside a code editor; it lives inside your browser context with full console and debugger access, which means it can actually see runtime errors and DOM state while you browse. That’s a genuinely different take on “agentic” than yet another Copilot sidebar.

Key highlights

• Bring-your-own-key for all major providers (OpenAI, Anthropic, Google, DeepSeek, Moonshot, Alibaba, Z.ai, MiniMax) plus custom local inference endpoints
• Tiered hosted option ($0/$20/$200) if you don’t want to manage API keys
• AGPLv3, developed by stagewise GmbH
• Reverse-engineering tools for scraping component styles and palettes from live sites
• IDE integration to sync changes with your existing editor

Caveats

• The README is heavy on subscription pricing and light on architecture; how the agent actually orchestrates tasks is left unsaid
• Account creation is mandatory even if you bring your own key, and the only distribution path mentioned is downloading from stagewise.io

Verdict

Worth a look if you want an agent that can inspect runtime behavior while you browse, but pass if you prefer to self-host the entire stack or need detailed documentation on the agent’s internals.
