The Open Source Agentic IDE
stagewise is building the open-source agentic IDE: a developer workspace for creating and orchestrating coding agents, previewing running apps, and managing Git workflows. Developers can run agents in parallel, use their preferred models or existing coding subscriptions, and keep agents connected to browser/runtime context as well as the broader codebase, from APIs and tests to docs and deployment paths.
stagewise is an open-source IDE focused on creating and orchestrating coding agents. it emphasizes agentic coding, running git workflows, and using multiple model providers within an extensible, open ecosystem built for developers.
Provides an agentic coding environment where users create and orchestrate coding agents, preview apps, and run git workflows. It supports multiple model providers (including local models) and allows parallel execution of agents, caching to improve performance, and dynamic context management for long-running tasks. The product is open-source, extensible, and designed to work with popular coding subscriptions and various model providers through a unified stagewise account or by connecting existing subscriptions.
Who it’s for: developers and AI/ML practitioners who build, test, and deploy coding agents or AI-assisted workloads; teams needing a centralized environment to orchestrate agents and workflows.

Co-founder and CEO of stagewise, the frontend coding agent for real codebases. Studied electrical engineering at DHBW Mosbach and in partnership with Rheinmetall, focussing on functional safety in automotive embedded software. Led the efforts for development and adoption of a state-of-the-art componentization framework for embedded software at Miele, before making a pivot to artificial intelligence and web technologies.
Founder/ CTO of stagewise.io, a frontend coding agent that lives inside your browser on localhost. As a core engineer, I helped scale saasmetrix. I also built a PLG product strukto.io that helped fellow CS students from 0 to 5,000 MAU. I love building great products.
Visually build your apps frontend right inside your browser on localhost.
Stagewise launches an open-source frontend coding agent that integrates into a local web app to iteratively modify production-grade frontends via in-app prompts and element annotations. It targets teams building production apps and aims to reduce context switching by handling frontend changes directly in the browser.
