A developer announced xc, a cross-platform compiler with Objective-C-like syntax that runs on Mac, Windows, and Linux and can generate binaries for multiple targets including iOS, Android, WASM, and retro platforms like 6502. The GPL3-licensed compiler is self-contained after bootstrapping, includes optimization passes and interoperability features for binding C libraries, and has been extensively tested with over 600 unit tests and real-world applications.
Flet, a Python framework for building cross-platform apps, released version 1.0 after four years of development, marking readiness for production use. The release includes comprehensive testing across platforms and Python versions, improved documentation generation, and performance enhancements like faster UI reconciliation and direct Python-to-Dart communication.
Capsule is a platform that packages complete web applications—UI, data, and SQLite database—into single portable .capsule files that run offline without cloud infrastructure. Users can generate self-contained apps from AI prompts and share them like documents via email or messaging apps, with full cross-platform support for macOS, Windows, Linux, and upcoming iOS/Android versions.
GPUI-CE is a GPU-accelerated UI framework for Rust forked from Zed's GPUI, offering a hybrid immediate/retained rendering model with native performance across macOS, Windows, and Linux. Independently governed and MIT/Apache-2.0 licensed, it provides developers a community-maintained alternative for building fast native UIs without editor-specific dependencies.
Shortcut Express is an interactive desktop course that teaches keyboard shortcuts through guided lessons tied to real problems, covering essential shortcuts for text navigation, selection, editing, and browser tasks across Windows, macOS, and Linux.
Pragtical 3.12, a lightweight Lua-scriptable code editor, introduces a modular rendering system with an optional SDL-based GPU backend while maintaining its 50MB RAM and 10MB install footprint. The GPU backend targets Vulkan, Direct3D 12, and Metal for cross-platform support, offering benefits for high-DPI displays and large files, though it trades some memory overhead for efficiency gains. The release also adds trust prompts for project modules to prevent arbitrary Lua execution.
Slint is a declarative GUI framework for Rust that enables developers to build elegant, native, cross-platform user interfaces using a domain-specific language similar to HTML/CSS. It features live preview, Figma integration, responsive design capabilities, and is used by companies like OTIV, WesAudio, SK Signet, and Aava for production applications in rail automation, audio workstations, EV charging, and plugins.
Flectar Mail is a lightweight, native email client built in Rust that uses only 20–140 MB of RAM compared to 800+ MB in typical clients. It offers cross-platform support for Windows and Linux with macOS and mobile versions in development, featuring a custom HTML/CSS renderer and customizable UI layouts and themes.
Aqorin Phone is an open-source, cross-platform SIP softphone built with .NET that enables users to make and receive calls using standard SIP credentials without requiring proprietary accounts or ecosystems. The application offers essential calling features including muting, holding, contact management, and call history, with support for both manual SIP configuration and router profiles. It uses standard SIP signaling and RTP audio, making it compatible with PBX systems and router-hosted phone accounts.
A developer spent one afternoon building a casual cross-platform game with the help of a coding agent, spending lunch writing a detailed 15-section specification before implementation. The game involves tapping water to create ripples that push colored petals toward matching lily pads in a circular pond, with physics designed for deterministic, crisp gameplay.
Game Index is a unified game library manager that aggregates Steam, GOG, Epic, and other game stores into a single launcher with cross-platform support, built natively for Linux with Proton/Wine compatibility, achievements, social features, and a controller-friendly interface.
