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. -

Apple Wallet Card Skinner for iOS 18+ (No Jailbreak Required)
AirCard is an open-source macOS utility for visually customizing Apple Wallet cards and lock-screen passcode buttons on supported iPhones. It can apply custom artwork, textures, or bank-style designs to individual Wallet cards without requiring a jailbreak. The application also imports and applies .passthm lock-screen keypad themes on supported iOS versions. A built-in creator can generate themes from a single image or let users design individual keypad buttons. Existing themes can be opened, repositioned, edited, previewed, and exported again. AirCard connects to the iPhone over USB and uses the Airlift AirTraffic synchronization technique to apply supported visual changes. Universal macOS builds include required communication and image-processing components for both Apple Silicon and Intel Macs. -

EeveeSpotify
A tweak to enhance Spotify experience
EeveeSpotifyReborn is an unofficial modification for the Spotify mobile application that alters client-side behavior to unlock premium-like features without requiring a paid subscription. It operates by injecting changes into the Spotify app, making it interpret the user account as having premium access and enabling functionalities that are normally restricted. The project was developed through reverse engineering techniques, including analyzing application behavior and intercepting requests to replicate premium functionality within the client environment. It also extends the base experience by adding features such as alternative lyric providers, enabling more flexible and enhanced lyric display compared to the default implementation. The tool requires users to build or sideload a modified application package, as distribution of prebuilt binaries is restricted due to legal concerns. -

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. -

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. -

PhoneNumberKit
A Swift framework for parsing and formatting phone numbers
Swift 5.3 framework for parsing, formatting and validating international phone numbers. Inspired by Google's libphonenumber. Import PhoneNumberKit at the top of the Swift file that will interact with a phone number. All of your interactions with PhoneNumberKit happen through a PhoneNumberKit object. The first step you should take is to allocate one. A PhoneNumberKit instance is relatively expensive to allocate (it parses the metadata and keeps it in memory for the object's lifecycle), you should try and make sure PhoneNumberKit is allocated once and deallocated when no longer needed. To parse a string, use the parse function. The region code is automatically computed but can be overridden if needed. PhoneNumberKit automatically does a hard type validation to ensure that the object created is valid, this can be quite costly performance-wise and can be turned off if needed. -

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. -

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. -

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.
