Latest News
Noop v0.1.10 released with event-driven task scheduling, backoff-based CI waits, offline-machine reassignment, improved routines, and owner-controlled merge decisions.
Noop v0.1.9 released with stable chat scrolling, a user Done button, and support for Claude background subagents to finish before a turn completes.
Native Shell v0.4.0 released with shaders, form controls, rich editing, charts, browser-engine web apps, and broad performance/platform improvements.
GPUI Kit v0.9.0 released with editor and diff decorations, icon resolution, configurable cursor blinking, accessibility improvements, and text/rendering fixes.
Products & Services
A Rust native UI framework for iOS, Android, macOS, Windows, Linux, and the web. It shares components, state, logic, and APIs while rendering with platform-native views and supports Rust, TSX, embedded apps, standalone apps, and signed run-time modules.
A Rust desktop application framework built on GPUI, formerly GPUI Component. It provides components, layouts, data tables, docking, charts, editors, application tools, and GPUI Shell for JavaScript plugins/extensions on macOS, Windows, and Linux.
An open-source personal AI team that runs Claude Code and Codex agents on the user's own computers. It decomposes goals, runs work in parallel, learns decision preferences, and asks the owner only for decisions that need human input.
A drop-in Cargo fork tuned for fast local builds and bounded disk usage by sharing one build directory across git worktrees while keeping it under a size limit.
Market Position
Lee's work is positioned around open-source, native-performance alternatives to Electron-style desktop applications: GPUI Kit supplies a broad application/component layer on top of GPUI, while Native Shell extends the native Rust approach across mobile, desktop, and web platforms. Noop is differentiated from hosted AI-agent products by running on the user's own computers and Cloudflare account, with local control, human decision gates, and no shared service. Comparable alternatives include Electron and other cross-platform UI frameworks, Zed/GPUI-based ecosystems, and hosted AI coding-agent/orchestration services.
Leadership
Founders
Jason Lee (huacnlee)
Started professional software development in 2006 and discovered Ruby in 2009. From 2011 to 2018 he worked at Taobao, Alibaba, and Ant Financial on advertising backends, YunOS infrastructure, Rails applications, the Aliwangwang Mac client, the Xiami Music Mac client, Egg.js, Alibaba GitLab, and Yuque architecture. He co-founded Ruby China in 2011 and is now Technical VP at Longbridge while creating and maintaining open-source Rust software.
Executive Team
Jason Lee
Technical VP at Longbridge; independent open-source creator
Creator of Native Shell and GPUI Kit, co-founder of Ruby China, and contributor to Zed/GPUI. Previously worked at Taobao, Alibaba, and Ant Financial from 2011 to 2018.
Founding Story
Lee says he began using computers in 2000 and professional development in 2006; Ruby and Rails shaped his technical approach after 2009. In 2011 he co-founded Ruby China to help Ruby and Rails grow in China, initiated the RubyGems Taobao mirror to make dependency installation easier in China, and later moved the mirror to independent Ruby China maintenance. His current work grew from practical needs building native software: GPUI Kit was developed alongside Longbridge Pro, while Native Shell and related tools pursue shared logic with native platform rendering.
Business Model
Revenue Model
The subject's public work is primarily open source. Noop runs on the user's own machines and free Cloudflare account, and its repository invites GitHub sponsorship; no product subscription or paid API model is stated in the inspected sources.
Pricing Tiers
The Noop documentation says the primary machine uses the user's Cloudflare account and that the free plan is enough; the software is open source and self-hosted.
