ArtCraft is a desktop IDE for interactive AI image and video creation, developed by Storytold. It lets artists compose in 2D, stage scenes in 3D, and select models for image, video, music, sound, 3D-mesh, and world generation. Its visual tools include 2D and 3D compositing, image-to-location scene planning, image-to-3D mesh conversion, character posing and identity transfer, kitbashing, background removal, canvas editing, masking, inpainting, prompted image editing, text-to-image generation, and image-to-video animation. The project supports integrations including ArtCraft's catalog, Grok, Midjourney, Sora, and World Labs, and is distributed through stable Windows and macOS releases; Linux users can build it from source.

Asm is a package registry and command-line tool for assembly-language projects. It creates, builds, runs, tests, and distributes projects with explicit machine targets, source dependencies, repeatable lock files, and release records containing source, commit, artifact, size, SHA-256, and verification information. Its commands support package search, version inspection, source fetching, executable installation, upgrades, and uninstalling; publication is submitted through reviewed pull requests. The CLI supports Linux x86-64, Linux ARM64, and Apple Silicon macOS 15 or later, with RISC-V Linux packages and additional target implementations supported in the project model. Asm is in early alpha and is licensed under AGPL-3.0-or-later; starter code and reference examples use MIT.

blaze is an incremental Rust build tool that replaces selected Cargo commands, including build, check, run, test, and bench. Its daemon keeps the project compiled in memory; after an edit, it compiles only the changed functions and links the program with its own linker, enabling millisecond-scale rebuilds and live edits to a running program. It uses its own Rust toolchain and supports macOS on Apple silicon and Linux. The tool trades memory for speed, requires several gigabytes for a small project, and is distributed under the MIT or Apache-2.0 licenses.

cinecode is an MIT-licensed open-source kit for Claude Code and Cursor that directs an AI coding agent to create short films, long videos, advertisements, explainers, and music videos. The agent turns a brief into a script and production plan, presents style and scene approvals, builds frames as code using Canvas 2D or Three.js/WebGL, designs synchronized sound, renders previews and final video, and delivers an MP4. It supports a Quick mode for shorter productions and a Film mode with staged approvals, research, storyboards, animatics, revisions, and final rendering. The repository includes camera and transition vocabularies, style presets, typography and sound-design guidance, beat-grid music-video tools, text-to-speech options, asset and license tracking, quality-control scripts, and headless Chrome, FFmpeg, Node.js, and Python-based rendering tools.

Hallmark is an open-source design skill for Claude Code, Cursor, and Codex that applies anti-AI-slop rules to generated interfaces. It selects a macrostructure and one of twenty-one themes for a brief, applies its design rule set, runs fifty-seven anti-pattern gates and a pre-emit self-critique, and returns self-contained HTML and CSS. Its four operations build new UI, audit existing code without editing it, redesign an interface while retaining its copy, information architecture, and brand, or study a screenshot or URL to extract macrostructure, type pairing, and a color anchor; the study operation can also emit a portable design.md file. Custom briefs can receive a made-to-measure palette, typography, and layout rather than a catalog theme. Hallmark is made by Together AI and distributed under the MIT license.

hop is a Windows application for installing Linux alongside Windows without a USB stick. It checks the PC and selected drive, downloads and verifies a Linux ISO from official sources or accepts an existing ISO, creates a FAT32 installer partition on an internal disk, copies and checks the ISO files, adds a one-time startup entry using the ISO's signed bootloader, and restarts into the Linux installer. It can make space by using existing free space or shrinking a Windows drive, and can undo an installation or remove another Linux installation. Supported systems include Ubuntu and its flavours, Linux Mint, Pop!_OS, Zorin OS, Debian, Fedora Workstation, Arch Linux, Omarchy and others, with system-specific limitations such as Secure Boot or BitLocker requirements. It requires Windows 10 version 1803 or newer or Windows 11 on a UEFI PC with a GPT disk; Linux must be installed on a disk inside the PC. The project is distributed as hop.exe and is licensed under the MIT License.

mpv is a free, open-source command-line media player developed by the mpv project. It plays a wide range of audio and video formats, codecs, and subtitle types, using FFmpeg for media handling, libass for on-screen display and text subtitles, and GPU shaders for video rendering and scaling. Optional features include hardware decoding, Lua scripting, screenshots, and native DASH playback. It runs on Linux, Windows, and macOS and is licensed under GPLv2 or later by default, or LGPLv2.1 or later when built with the GPL components disabled.

NectarLink is a free, open-source application that connects an Android phone with a Windows PC, Linux computer, or preview macOS client. It provides notifications, messaging, calls, clipboard and file transfer, photo access, screen mirroring, phone apps in desktop windows, remote phone and PC controls, phone-as-webcam support, and audio features. Devices pair by QR code or a six-digit code and communicate directly over a local network or USB, without an account or cloud service. Connections use QUIC with TLS 1.3 and device keys; each feature has its own per-device permission switch. The shared Rust core handles pairing, sessions, storage, protocol, and capability negotiation, while the Windows desktop app uses Qt Quick and Rust and the Android app uses Kotlin and Jetpack Compose. The project distributes Windows and Android builds through GitHub Releases and documents Linux packages and a macOS preview. The applications and command-line client use GPL-3.0-or-later, core libraries use MPL-2.0, and the protocol documentation uses CC BY 4.0.

Nushell is a cross-platform command-line shell that treats data as structured values rather than raw text streams. Its pipelines compose commands that produce, filter, and consume streams, allowing operations such as listing directory records, filtering them by fields, inspecting processes, and loading structured files such as TOML. Nushell supports plugins that communicate through a JSON-RPC protocol and follow the shell's structured-data model. It has first-class support for Windows, macOS, and Linux, is distributed under the MIT license, and the project describes its current quality as minimum viable product with some commands potentially unstable.

OpenMontage is an open-source, agent-driven video production system that turns plain-language instructions into video projects through an AI coding assistant. Its workflow covers research, scripting, production planning, asset generation, editing, and final composition, with production pipelines, approval gates, cost estimates, and post-render checks. The system can produce image-based videos as well as videos assembled from real motion footage: its agent can build a corpus from free stock footage and open archives, retrieve clips, edit them into a timeline, and render the result. It runs locally with FFmpeg and Remotion and includes 12 production pipelines, more than 100 tools, and hundreds of agent-skill and production-knowledge files.

OpenSSL is an open-source cryptographic toolkit and security project for TLS, Datagram TLS (DTLS), and QUIC, developed by the OpenSSL Project. It includes libssl, implementing TLS and DTLS through version 1.3 and QUIC version 1; libcrypto, a general-purpose cryptographic library usable independently; and the openssl command-line tool for key generation, X.509 certificates, CSRs and CRLs, message digests, encryption and decryption, protocol testing, and S/MIME operations. OpenSSL also provides implementations of the post-quantum algorithms ML-DSA and ML-KEM, includes a cryptographic module validated to conform with FIPS standards, and is licensed under the Apache License 2.0. The project distributes source code, maintains a public GitHub mirror, and is commonly provided as precompiled binaries by operating-system vendors.

Poki is an open-source tool that lets AI agents operate a real iPhone through a local MCP server and agent, without jailbreaking or additional hardware. It connects an iPhone to a Mac, exposes device-control tools to MCP clients such as Claude Code and Codex, and sends screen contents to the configured model service. Poki can also run a standalone terminal agent and authorized iMessage or Telegram channels. It requires macOS 15 or later, full Xcode, Node.js 24 or later, and a physical iPhone paired with the Mac over USB; the project documents limits including portrait-only support for verified physical devices. It is licensed under AGPL-3.0-only.

Prometheus is a Cloud Native Computing Foundation monitoring system and time-series database. It collects metrics from configured targets at intervals, evaluates rule expressions, displays results, and can trigger alerts when specified conditions occur. Its architecture uses a multi-dimensional time-series data model, the PromQL query language, an HTTP pull model, service discovery or static target configuration, and autonomous single-server nodes without a dependency on distributed storage. It is distributed as precompiled binaries, Docker images, and source code, with graphing, dashboarding, federation, and an intermediary gateway for batch-job metric pushes.

Quiet.md is a local-first notes application for macOS and Windows, drawn natively with Rust and GPUI rather than a WebView or Electron. It stores each note as a Feishu/Lark DocxXML file in an ordinary local folder, with no account, cloud service, or network activity by default. The rich-text editor supports headings, lists, to-dos, tables, columns, callouts, syntax-highlighted code blocks, LaTeX math, images, attachments, and covers. It can import Markdown and Feishu/Lark DocxXML, export Markdown and PDF, print directly, and preserve structure when pasting from Feishu or web pages. The app also provides document trees, pinning, favorites, full-text search, trash, configurable keyboard shortcuts, and built-in or custom themes. It is distributed for Apple Silicon Macs running macOS 13 or later and x64 Windows systems running Windows 10 version 2004 or later; the source code is licensed under MIT.

Rerun is an open-source, self-hostable application for setting up teams of AI coworkers. A Foreman interprets plain-language requests, plans the team, and creates coworkers with separate jobs, skills, memory, and computers. Coworkers can use browsers and connected tools, collaborate on tasks, run on schedules or webhook triggers, and pause for approval before sending, paying, or deleting anything. It supports MCP servers, Composio integrations, and a catalog of ready-made integrations, and can use API keys, existing Claude or ChatGPT subscriptions, or models served through Ollama, LM Studio, vLLM, or an OpenAI-compatible server. The application is built as a Next.js and React frontend with Supabase, a per-workspace engine, the Vercel AI SDK, Hono, libSQL, Patchright, and Docker in a pnpm monorepo. The repository is licensed under AGPL-3.0. Self-hosting requires Docker, Node.js 22, a Supabase project, and an OpenRouter key according to the setup instructions. Some directories covering billing, plans, credits, managed models, and the template marketplace use the Rerun Commercial License.

An agent skill by caru-ini that turns a natural-language description of a technology stack into an architecture diagram with official logos. It works with Claude Code, Codex, Cursor, and other agents supporting skills, and can depict application infrastructure, development tooling, AI applications, and cloud environments including AWS, Google Cloud, and Azure. The skill fetches logos at build time, routes connector lines around labels, and renders light and dark versions. It produces a self-contained HTML file, PNG, dependency-free React component, or Artifact; PNG export uses Playwright with Chromium. It requires Python 3.9 or later and network access for logo retrieval. The code and documentation are MIT-licensed, while bundled fonts use the SIL Open Font License 1.1.

Symfony is an open-source PHP framework for web and console applications, accompanied by a set of reusable PHP components. It is installed with Composer and follows semantic versioning, with long-term-support releases and a predictable release process. Development is led by the Symfony Core Team and supported by community contributors.

UNCUT is a headless coding-agent harness written in Go for shell pipelines, CI jobs, containers, and agent experiments. It sends the complete conversation, file contents, and command output to an OpenAI-compatible Chat Completions endpoint through one agent loop with four tools: read_file, write_file, replace, and run_command. The tool does not summarize, prune, compact, or silently truncate context; provider-side response truncation is reported as an error instead of being presented as a successful partial answer. It accepts piped UTF-8 input, can emit structured NDJSON events, and optionally stores complete resumable sessions in append-only JSONL files. UNCUT is distributed as a statically linked Go binary for Linux, macOS, and Windows, supports local OpenAI-compatible endpoints, and is released under the MIT license. It is not a sandbox: shell commands run with the operating system user's permissions.
