Jutsu IDEWeb3 IDE for NEAR

Jutsu IDE is a web IDE for NEAR's Blockchain Operating System, where front ends are React-style components stored on-chain and rendered by the NEAR Social VM. Developers write components in a CodeMirror editor, see them render instantly in a sandboxed live preview with a console that captures their logs, and publish them to NEAR mainnet or testnet with a storage-cost estimate before they sign. Around the editor sit an AI copilot that writes, explains, documents and debugs components, Live Share for editing the same component together in real time, GitHub import and push, forks and pull requests with a side-by-side diff, interactive tutorials with runnable code, and IPFS storage for assets. I built most of it: the React front end, the Express and MongoDB API behind accounts, projects, forks, pull requests and GitHub sync, and the copilot service on OpenAI and Anthropic models. The screenshots show the IDE running locally with a demo workspace and made-up data.
