Backstage

Inline is a work-chat app for teams, built by a two-person team. Its macOS and iOS clients organize conversations around numbered, optionally titled threads, direct messages, Spaces, and a sidebar of chats requiring attention. The project is designed for focused asynchronous and real-time collaboration, including sharing links to threads and using them for feedback, bug tracking, specifications, brainstorming, meeting notes, and team libraries. The app targets fast startup, low CPU and RAM usage, and high frame rates. The video describes voice and screen sharing and a Rust-based WebRTC stack; the repository also lists a public API, command-line interface, SDKs, bot integrations, a hosted MCP server, and plugins for AI clients and OpenClaw. macOS and iOS are in beta, while web, Android, Windows, and Linux support are planned. Inline is currently free to use and in beta. The repository states that its server and native client source code are closed for now, while the protocol, CLI, MCP server, SDKs, plugins, and related development packages are published under the Apache License 2.0. The repository is the official source for building on top of Inline, not for the closed core application.

Design Studio AI is an open-source, agent-first design workspace for humans and AI agents. It supports web interfaces, slides, reports, wireframes, 3D scenes, and timeline videos; users start from a brief or template, inspect a preview, revise through chat or a manual editor, and work together on the same versioned document. The workspace provides structured flex/grid layouts, reusable design systems, 2D character motion, editable 3D scenes, BYOK text/image/speech/music/video generation, and exports including JSON, HTML, SVG, PNG, PDF, PowerPoint, WebM, GLB/glTF, React prototype ZIPs, and authorized Google Slides. It exposes REST, authenticated MCP, experimental WebMCP, and a CLI for agent access, and can run on Cloudflare or be self-hosted with Docker and persistent SQLite/files. The repository is distributed under the MIT license.

Next.js is an open-source React framework developed by Vercel for building full-stack web applications. It extends React with server rendering, static-site generation, hybrid rendering, components, and routing, and integrates Rust-based JavaScript tooling for builds. The project provides documentation, a learning course, a showcase, community discussions, and contribution guidelines.

PortalJS is an open-source, AI-native framework maintained by Datopian and its community for building data portals. Its agentic skills advise on storage, compute, catalog, access, hosting, and metadata, then scaffold the result as plain, editable Next.js code. Claude Code skills can create a portal, add CSV or JSON datasets, connect to backends such as CKAN, and deploy it; generated portals include a home page, catalog, and dataset showcase, with support for configurable data providers, charts, maps, and schemas. A bare template is also available without the AI skills, and the project presents Git, object storage, Parquet, and DuckDB as an optional modern architecture while retaining traditional datastores as supported choices.

gstack is an open-source skill and tooling framework for Claude Code, developed by Garry Tan. It turns Claude Code into a virtual engineering team through Markdown-based slash commands and specialist roles covering product review, engineering management, design review, code review, browser-based QA, security auditing, release management, documentation, and other software-delivery tasks. Its tools can drive a real browser and support unit-test, end-to-end-test, and black-box verification loops. The repository describes 23 specialist tools and eight power tools, and distributes the project under the MIT license. It requires Claude Code, Git, and Bun; Node.js is additionally required on Windows.
