Huzzah is an experimental editor that offers a new paradigm for working with LLMs. Instead of writing longform, imperative prompts that are discarded after use, you write terse, declarative pseudocode that persists as the source of truth. This pseudocode acts as both the prompt and documentation, and Huzzah automatically generates real code from it. It's a more efficient, readable, and controllable way to leverage AI for coding, giving you the benefits of AI assistance without losing insight or control over your codebase.
Zoneless is an open-source payout platform that lets you pay sellers and creators anywhere, without fees. It works alongside Stripe or PayPal, using the same API you already know, so switching is as easy as adding a new option. With near-zero payout fees, support for 220+ countries, and self-hosting capabilities, Zoneless offers a transparent, cost-effective alternative for marketplaces. Try it in test mode and see the savings for yourself.
Doubly Blackbox Checker is a free tool that helps songwriters discover unclaimed mechanical royalties at The MLC. By pasting a Spotify link or searching by name, you can see which of your recordings are missing, unmatched, or have unclaimed shares, and estimate the money stuck in the 'black box.' It leverages The MLC's public data to provide a clear status for each recording, from 'Looks good' to 'Missing work,' and explains how to fix issues. With a user-friendly interface and detailed explanations, it empowers artists to protect their earnings before the 2027 market-share distribution.
UpLink is a custom-built, ultralight high-altitude balloon payload that captures and transmits high-resolution images from the stratosphere. Designed with 3D-printed enclosures, redundant tracking, and an efficient radio link using SSDV, it sends detailed photos to the ground in near real-time. The project explores innovative insulation materials and offers open-source firmware and hardware designs, making it a valuable resource for amateur ballooning enthusiasts.
Omacosy brings the omarchy desktop experience to macOS with a real Super key, Hyprland's dwindle layout, and a themed status bar. It features focus-follows-mouse, trackpad workspace swipes, live workspace overview, and unified theme switching. Built with self-contained Swift binaries, it runs without disabling SIP and idles at ~157MB memory footprint. Ideal for users seeking a highly customizable, efficient tiling window manager with a cohesive aesthetic.
An open, structured database of 3,430 CCTV/IP camera models across 77 brands, from budget WiFi cams to enterprise PTZ and thermal systems. Each camera is a validated JSON file aggregated into a queryable dataset (JSON + CSV). The companion web app at cctv-database.com lets you search, filter, sort, and copy ready-to-use Frigate configs. The dataset is CC0 and includes RTSP patterns, schema validation, and a QA tool. Ideal for choosing Frigate-compatible cameras or integrating camera specs into your own projects.
Why You Lost is a Dota 2 analytics tool that transforms post-match analysis into a data-driven autopsy. Paste your match ID and face the numbers: every decision is measured against cohorts of current-patch matches from SereneDB, providing win-rate deltas with real sample sizes. No coaching platitudes—just hard data to reveal why you lost. Perfect for players who want to improve by understanding the impact of their choices, backed by up-to-date patch statistics.
WaveHouse is an open-source, single-binary API gateway that turns ClickHouse into a real-time, user-facing analytics platform. It abstracts away the complexities of direct frontend-to-ClickHouse integration—like 'too many parts' errors, Kafka queues, and custom deduplication logic—by providing schema-validated ingest, async buffered writes, native SSE streaming with gap-fill, and Hasura-style row/column security. With a TypeScript SDK, you can query and subscribe to live updates in minutes via Docker Compose. Self-host it or use the managed cloud; it's Apache 2.0 licensed with no vendor lock-in.
LilScript is a typed, compression-first programming language that compiles to highly optimized JavaScript, making libraries 5-15% smaller after gzip/brotli compression compared to tools like esbuild and terser. It achieves this by reshaping the program structure, eliminating unnecessary objects, and intelligently renaming variables based on the target compression algorithm. Proven to reduce VSCode's core modules by 20% and speed up the marked markdown library by 10%, LilScript works with most JS/TS libraries. Ideal for developers seeking to minimize bundle sizes and improve load times.
Kandelo is a groundbreaking kernel that brings POSIX compatibility to the browser by running multiple WebAssembly processes concurrently. It offers a full virtual file system and a familiar Unix-like environment, enabling developers to run complex, multi-process applications directly in the browser without servers. With its lightweight design (kernel and VFS under 6 MB), Kandelo opens new possibilities for edge computing, collaborative tools, and portable applications. Experience the future of browser-based computing by trying the live demo, and see how Kandelo bridges the gap between native and web environments.
Tether bridges your iPhone to a Linux Wayland desktop, bringing Apple Continuity features to Linux. It offers clipboard sync, file transfer, SMS/iMessage messaging, and notification mirroring via Bluetooth, plus a browser/mail extension for OTP handling. With an iOS app, CLI, and GTK GUI, Tether provides secure mTLS connections and aims to support all technically possible Continuity features. Ideal for users who've left macOS but still use an iPhone.
ParqDB brings vector search directly to your browser by streaming Parquet files over HTTP. It leverages WebAssembly and range requests to efficiently query large datasets without a server-side search engine. Perfect for exploring Wikipedia-scale corpora, ParqDB delivers fast, interactive search experiences while keeping your data in open formats. Try the live demo to see instant results from millions of documents, all within your browser.
Sci-Trust is a viewer-relative reading tool for scientific research. It infers trust relationships from citation graphs, so each researcher sees a different ranking of papers, weighted by whom they trust. This makes it harder to game than citation counts and helps users onboard into subfields, trace intellectual lineage, or find papers respected by researchers they admire. It's also a read-only demonstration of UpTrust's trust algorithm, which can be applied to votes, peer reviews, and social networks.
SITMAP is a web-based map editor that lets you create Cold War era scenarios with a World in Conflict aesthetic. It uses Natural Earth map data and SVG icons from game-icons.net and Font Awesome, allowing you to drag, pan, and zoom to craft detailed maps. Perfect for wargamers, historians, and game developers, SITMAP is open-source and available on GitHub, making it easy to contribute or customize for your own projects.
