ModelHub is an essential native macOS menu bar application tailored for developers who actively work with local Large Language Models. This intuitive tool simplifies the entire process of discovering models from Hugging Face, downloading the correct local builds, and efficiently managing your growing model library. It allows you to seamlessly integrate and use Hugging Face models with popular platforms like Ollama, MLX, LM Studio, and llama.cpp, along with your existing development tools. Say goodbye to the tedious task of switching between browser tabs, executing terminal commands, sifting through model cards, and navigating local folders; ModelHub provides the crucial discovery and management layer that these powerful tools truly needed.

Discovering the perfect domain name is a crucial step for any project. tldx is a blazing-fast, concurrent command-line interface (CLI) tool that streamlines this process by generating and checking domain availability in bulk using the modern RDAP protocol. You can effortlessly mix keywords, prefixes, suffixes, or even regular expressions to generate a wide array of potential domains, and then stream the results directly to stdout, JSON, or CSV format. Additionally, tldx incorporates an MCP server, giving AI agents, such as Claude, the power to automatically brainstorm and verify domain names on your behalf. Installation is simple via Homebrew (brew install tldx). Bid farewell to frustrating rate-limits and outdated whois parsing. tldx is 100 percent Free and Open Source, built with efficiency in Go.

Pi is an elegant, minimal terminal coding harness designed to seamlessly integrate into your existing development workflows, rather than forcing you to adapt to it. This highly customizable tool empowers you to personalize your coding environment with a wide range of extensions, specialized skills, tailored prompt templates, and custom themes. You can easily bundle these customizations into Pi packages and share them with the community via npm or git. While Pi comes equipped with powerful default functionalities, it intentionally focuses on core capabilities, foregoing features like sub-agents and complex plan modes for a more direct approach. Simply ask Pi to build what you need, or effortlessly install a package that perfectly aligns with your preferred coding style.
