The score comes from our model.

• Show HN: OpenCode server and TUI in a browser tab (Chrome desktop) · score 8.3

  Browser Agent Toolkit runs the OpenCode coding agent server, a POSIX-like shell, and a dev server entirely inside a Chrome tab using a custom Rust/WASM kernel and shared memory, eliminating server-side sandbox costs. It enables in-browser code editing for web apps with live hot-reload, leveraging the real OpenCode agent rather than a reimplementation. The project is experimental but demonstrates a novel architecture combining a WASM kernel, immutable dependency images, and cross-origin isolation for secure agent execution.

• Show HN: Red Alert 2 Runtime in the Browser – With Yuri's and Multiplayer · score 8.3

  RA2 VM runs the original Red Alert 2 and Yuri's Revenge executables directly in the browser using v86 x86 emulation, custom firmware, and a Win32/DirectX compatibility layer, without booting Windows. It supports campaigns, skirmish, save/load, multiplayer via a WebSocket relay, and even experimental AI agent control. This is a technically ambitious project that bypasses engine reimplementation by emulating the original game binaries, enabling niche features like Mental Omega support while raising legal distribution questions.

• Show HN: Pixel-exact HTML-to-PDF in the browser, no Puppeteer or server · score 8.3

  daepdf is a browser-based HTML-to-PDF engine that uses Rust and WebAssembly to capture the exact layout rendered by the browser and rebuild it as a real PDF with selectable text, vector SVGs, and embedded fonts. It eliminates the need for server-side rendering or headless browsers, offering pixel-perfect PDFs directly in the browser.

• Show HN: Cooja-NG – IoT network emulator running real firmware in the browser · score 8.0

  Cooja-NG is a clean-room C re-implementation of the Cooja/MSPSim IoT network emulator, supporting multiple architectures (MSP430, ARM Cortex-M, RISC-V) with cycle-accurate simulation and browser-based visualization via WebAssembly. It passes the full Contiki-NG test suite and offers deterministic, high-speed headless CI testing for embedded wireless networks, making it a practical replacement for the Java-based Cooja.
