Proton VPN for iOS and macOS
Official ProtonVPN iOS and macOS app
The ProtonVPN iOS and macOS project contains the official code for the unified VPN client used on Apple platforms, delivering secure, encrypted network connections to Proton’s global servers directly from iPhones, iPads, and Macs. Written primarily in Swift with Apple platform conventions, this client lets users authenticate with their Proton accounts, select server locations, and manage advanced privacy features like automatic reconnection and DNS leak protection, tailored for Apple’s networking APIs. Because iOS and macOS have strict networking and extension models, the app uses system VPN configurations and integrates with native controls for background operation, seamless switching, and efficient battery usage. It supports both free and premium tiers of ProtonVPN, offering users flexible connection options while preserving Proton’s strict no-logs privacy policies. -

UTM
Virtual machines for iOS and macOS
UTM is a full-featured system emulator and virtual machine host for iOS and macOS. It is based off of QEMU. In short, it allows you to run Windows, Linux, and more on your Mac, iPhone, and iPad. UTM/QEMU requires dynamic code generation (JIT) for maximum performance. JIT on iOS devices requires either a jailbroken device or one of the various workarounds found for specific versions of iOS. UTM SE ("slow edition") uses a threaded interpreter which performs better than a traditional interpreter but still slower than JIT. This technique is similar to what iSH does for dynamic execution. As a result, UTM SE does not require jailbreaking or any JIT workarounds and can be sideloaded as a regular app. -

AltStore
AltStore is an alternative app store for non-jailbroken iOS devices
AltStore is an alternative app distribution system for iOS that works without a jailbreak by using your own Apple ID to sideload and periodically re-sign apps. It pairs with a companion desktop app, AltServer, running on macOS or Windows, which handles signing and pushing apps to your device over Wi-Fi or USB. Once installed, AltStore can refresh app signatures automatically, keeping them usable beyond the standard seven-day limit that applies to free developer profiles. Users can install featured apps as well as add third-party “sources,” enabling a wider ecosystem of utilities, emulators, and experimental tools that aren’t available through the official App Store. The design emphasizes safety and transparency: apps are signed with your credentials, you can see what’s installed and when it will expire, and you control which sources you trust. -

Maccy
Lightweight clipboard manager for macOS
Maccy is a lightweight clipboard manager for macOS. It keeps the history of what you copy and lets you quickly navigate, search, and use previous clipboard content. Unlike other Mac clipboard managers, Maccy does only one job - keep your copy history and let you access it fast. You won't be overloaded by unnecessary features. Maccy works blazingly fast. You can open and search your entire clipboard history in just a fraction of a second. Nothing should distract you from what you're focused on. Just type what you want to find in history and hit Enter. You don't need to use your mouse. Don't waste your time moving your hands away from the keyboard. Maccy respects your privacy. If your password manager removes a copied password from the clipboard, so will Maccy. Everything is stored on your computer. -

SideStore
SideStore is a fork of AltStore that doesn't require an AltServer
SideStore is an untethered, community-driven alternative app store for non-jailbroken iOS devices. SideStore is an iOS application that allows you to sideload apps onto your iOS device with just your Apple ID. SideStore resigns apps with your personal development certificate and then uses a specially designed VPN in order to trick iOS into installing them. SideStore will periodically "refresh" your apps in the background, to keep their normal 7-day development period from expiring. SideStore's goal is to provide an untethered sideloading experience. It's a community-driven fork of AltStore, and has already implemented some of the community's most-requested features. SideStore is a just regular, sandboxed iOS application. The AltStore app target contains the vast majority of SideStore's functionality, including all the logic for downloading and updating apps through SideStore. SideStore makes heavy use of standard iOS frameworks and technologies most iOS developers are familiar with. -

Zebra iOS
A Useful Package Manager for iOS
A modern, fast, and powerful open-source package manager for jailbroken iOS devices. The easiest way to install Zebra is to visit Zebra on your iOS device. This will guide you through the installation process. Zebra requires a jailbroken iOS device. Jailbreaking is the process that gives you access to the tweaks, themes, and other tools you can install through Zebra. You can find out how to jailbreak at cfw.guide. Zebra and jailbreaks are always free. Anyone suggesting you can install Zebra without a jailbreak, or accepting payment to download Zebra, is a scam. If you paid for Zebra or a jailbreak, contact your bank to file a chargeback. A stable release of Zebra for macOS isn’t yet available. You can build Zebra from source to try out the latest unfinished state of Zebra on macOS. You will need to install Procursus on your Mac, which is similar to Homebrew/MacPorts, but is based on the APT package management system Zebra is built for. -

eqMac
macOS System-wide audio equalizer & volume mixer
System audio equalizer for macOS. Professional grade Parametric EQ & volume mixer. If you feel like your audio device (Headphones or Speaker) does not have enough Bass (low frequency) punch, or vice versa, you can adjust that using eqMac. macOS does not have a direct way to access the System Audio stream, so we use the eqMac Audio driver to divert the system audio to the driver's input stream. Then eqMac captures that Input audio stream processes it, and sends it directly to the output device. Expert EQ, unlimited bands, fully customizable (Filter Type, Frequency, Gain, Bandwidth). Volume mixer, apply different volume levels per each application. Fully customize the look and feel of eqMac by changing the User Interface Colors, Feature visibility, and arrangement. Control all aspects of eqMac through a WebSocket API. Works with any programming language that supports WebSockets. -

AlDente
Menubar Tool to set Charge Limits and Prolong Battery Lifespan
AlDente is a MacBook battery-care app designed to extend battery lifespan by letting you set smart charge limits and monitor health over time. Instead of always charging to 100%, you can cap the maximum percentage so the battery spends less time at high voltage—one of the biggest contributors to wear. A compact menu-bar UI exposes live status, charge target, temperature, and optional protections like pausing charging when the laptop runs hot. Advanced modes help with real-world workflows: you can maintain around a target level while on AC power, calibrate periodically, or temporarily allow full charge before travel. The project emphasizes pragmatic defaults and clear explanations, so it’s approachable for non-experts yet flexible for tinkerers. By aligning day-to-day charging with best practices, AlDente helps users trade a small amount of peak capacity for meaningfully better long-term battery health. -

Popcorn Time for iOS
https://github.com/PopcornTimeTV/PopcornTimeTV
PopcornTimeTV was an Apple TV, iPhone and iPad application to torrent movies and tv shows for streaming. Since 2016, this project has grown exponentially - both in its user base and in its functionality. However, the team size has gone the other way. We went from having 13+ developers on the team to 1 developer and 1 designer, both of whom have lives and projects outside of Popcorn Time. We have decided that we have given our all to this project and it's time for us to move on to pursue greater things. There is no doubt that this comes with a heavy heart as we have learned so much from this project and watched it grow from this simple torrenting app that could only play 720p video, to what it is today. All that being said, we do not want this project to just die after we leave. The size of the project might be a bit daunting to an unseasoned developer but the app is extremely stable and packed with almost every feature you could need. -

SwiftLint
A tool to enforce Swift style and conventions
A tool to enforce Swift style and conventions, loosely based on the now archived GitHub Swift Style Guide. SwiftLint enforces the style guide rules that are generally accepted by the Swift community. These rules are well described in popular style guides like Ray Wenderlich’s Swift Style Guide. SwiftLint hooks into Clang and SourceKit to use the AST representation of your source files for more accurate results. You might want to move your SwiftLint phase directly before ‘Compile Sources’ step, to detect errors quickly before compiling. However, SwiftLint is designed to run on valid Swift code that cleanly completes the compiler’s parsing stage. So running SwiftLint before ‘Compile Sources’ might yield some incorrect results. SwiftLint hooks into SourceKit so it continues working even as Swift evolves! This also keeps SwiftLint lean, as it doesn’t need to ship with a full Swift compiler, it just communicates with the official one you already have installed on your machine. -

Pearcleaner
A free, source-available and fair-code licensed mac app cleaner
Pearcleaner is a small, native macOS utility that helps you fully remove applications by finding and deleting the leftover files they scatter across your system. After you drag an app into Pearcleaner (or select it from a list), it scans common Library locations for related caches, logs, preferences, containers, launch agents, and support files. Results are presented with clear paths and sizes so you can deselect anything you want to keep before sending items to the Trash. The tool favors safety: it avoids critical system areas, uses a conservative matching strategy, and relies on the Trash so you can restore items if you change your mind. Power users appreciate the transparency—no opaque “cleanup magic,” just an auditable list of what will be removed. For people who frequently test software or want to reclaim disk space after uninstalling large apps, Pearcleaner streamlines the tedious manual hunt through ~/Library and system folders. -

Designed with mobile usability in mind, it includes familiar gestures, thread views, swipe actions, attachment previews, and integrated search so users can stay productive on the go. It also handles common email needs like organizing with folders, setting flags, and filtering messages, while respecting platform norms for notifications, background fetch, and data usage. By maintaining a connection to the desktop Thunderbird project’s ethos, the iOS client places emphasis on transparency, extensibility, and user control. -
