TrustKit
Easy SSL pinning validation and reporting for iOS, macOS, tvOS
TrustKit is an open-source framework that makes it easy to deploy SSL public key pinning and reporting in any iOS 12+, macOS 10.13+, tvOS 12+ or watchOS 4+ App; it supports both Swift and Objective-C Apps. Simple API to configure an SSL pinning policy and enforce it within an App. The policy settings are heavily based on the HTTP Public Key Pinning specification. Sane implementation by pinning the certificate's Subject Public Key Info, as opposed to the certificate itself or the public key bits. Reporting mechanism to notify a server about pinning validation failures happening within the App, when an unexpected certificate chain is detected. This is similar to the report-uri directive described in the HPKP specification. The reporting mechanism can also be customized within the App by leveraging pin validation notifications sent by TrustKit. -

WhisperLive
A nearly-live implementation of OpenAI's Whisper
WhisperLive is a “nearly live” implementation of OpenAI’s Whisper model focused on real-time transcription. It runs as a server–client system in which the server hosts a Whisper backend and clients stream audio to be transcribed with very low delay. The project supports multiple inference backends, including Faster-Whisper, NVIDIA TensorRT, and OpenVINO, allowing you to target GPUs and different CPU architectures efficiently. It can handle microphone input, pre-recorded audio files, and network streams such as RTSP and HLS, making it flexible for live events, monitoring, or accessibility workflows. Configuration options let you control the number of clients, maximum connection time, and threading behavior so the server can be tuned for different deployment environments. On the client side, you can set the language, whether to translate into English, model size, voice activity detection, and output recording behavior. -

clash-rules
Clash Premium rule set (RULE-SET), compatible with ClashX Pro
clash-rules is a repository that provides rule sets and configuration files designed for proxy tools and systems like V2Ray / Clash — helping users to decide routing, blocking, or proxy behavior based on domain, IP, or other criteria. The repo aggregates many community-maintained lists: blocked domains, direct access lists, proxy-needed domains, geo-IP lists, and more — offering up-to-date and curated configuration data that reflects network conditions, censorship lists, or desirable routing policies. For users of proxy tools or privacy/VPN systems, having such rule lists saves the manual effort of compiling blacklists, whitelists, or routing rules, and helps ensure more reliable, consistent routing and access. The rules are maintained in text-based formats, making them easy to inspect, edit, or integrate into proxy configurations. Because the repository is publicly available, the community can contribute updates (e.g. newly blocked domains, improved routing heuristics). -

wxWidgets
Cross-Platform C++ GUI Library
wxWidgets is a C++ library that lets developers create applications for Windows, macOS, Linux, and other platforms with a single code base. It has popular language bindings for Python, Ruby, Lua, Perl, and several other languages, and unlike other cross-platform toolkits, wxWidgets gives applications a truly native look and feel because it uses the platform's native API rather than emulating the GUI. It's also extensive, free, open-source, and mature. -

Alpine.js
A rugged, minimal framework for composing JavaScript behavior
Alpine.js is a lightweight JavaScript framework designed to bring declarative, reactive behavior directly into HTML markup, functioning similarly in spirit to Vue but with a much smaller footprint. It’s often described as “jQuery for the modern web,” enabling you to sprinkle interactivity onto static HTML without needing a full SPA framework. You use directives like x-data, x-bind, x-on, x-if, and others to attach reactive state, event listeners, and conditional rendering straight in the DOM. Because Alpine is so minimal, it avoids virtual DOM overhead and focuses on being incremental and composable; you can use it for small interactive components inside traditional server-rendered pages. The project has grown a robust ecosystem (plugins, devtools, helper libraries) as people adopt it for micro-frontend patterns, admin panels, interactive widgets, and anything that benefits from having bits of reactivity without a heavy JavaScript framework. -

AxonHub
Use any SDK to call 100+ LLMs
AxonHub is an open-source AI gateway platform designed to simplify the process of integrating and switching between different large language model providers. The system acts as a compatibility layer that allows developers to use the same SDK interface while routing requests to various AI services behind the scenes. Instead of rewriting code when switching providers such as OpenAI or Anthropic, developers can simply change configuration settings within the gateway. AxonHub translates requests from one provider’s API format into another, enabling seamless interoperability across different AI platforms. The system also provides infrastructure features such as request routing, failover mechanisms, load balancing, and cost management for AI applications. This architecture makes it easier to experiment with multiple models and manage production deployments that rely on several providers simultaneously. -
