Hot
Hot is macOS menu bar application that displays the CPU speed limit
Hot is macOS menu bar application that displays the CPU speed limit due to thermal issues. CPU throttling is a power management technique in computer architecture whereby the frequency of a microprocessor can be automatically adjusted "on the fly" depending on the actual need, to conserve power and reduce the amount of heat generated by the chip. -

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. -

LinearMouse
The mouse and trackpad utility for Mac
The mouse and trackpad utility for Mac. If you are not comfortable with natural scrolling when using a mouse, LinearMouse can help you reverse the scroll direction. Since each device can be configured independently, there is no need to worry about the trackpad's travel address being affected. LinearMouse allows you to find comfortable cursor speed and acceleration and helps you move the pointer faster and more accurately. You can even disable cursor acceleration if you are a player or designer, to get the best pointer precision. -

SwiftLog
A Logging API for Swift
swift-log is the official, vendor-neutral logging API for Swift, providing a small, performant core that libraries and applications adopt to avoid logger lock-in. It defines common logging semantics and levels, plus a lightweight façade that backends can implement—so the same application code can run with different logging engines (e.g., OSLog on Apple platforms or custom sinks on servers). The package embraces Swift Package Manager, offers a clean Logger API, and is widely used across the Swift on server and Apple-platform ecosystems. The repo’s release notes and ecosystem links show active maintenance, CI coverage for recent Swift versions, and community-supplied backends. By decoupling the API from any one implementation, swift-log simplifies composition: frameworks can log consistently without dictating the logging stack to end users. It’s a foundational building block for production Swift services, tools, and apps looking for consistent, structured telemetry. -

KeyboardKit
KeyboardKit is a Swift library that helps you build custom keyboard
KeyboardKit helps you build custom keyboard extensions with Swift and SwiftUI. KeyboardKit is a Swift-based SDK that helps you build custom keyboard extensions with Swift and SwiftUI. It extends the native keyboard APIs and provides you with a lot of functionality. The KeyboardKit project is open-source and completely free. It's hosted at GitHub, which is where you find information, documentation, sample code, demo apps etc. KeyboardKit Pro is a license-based extension to KeyboardKit. It unlocks a bunch of pro features, like more locales, localized system keyboards, local and remote autocomplete etc. KeyboardKit comes with support for 50+ locales, with more being added over time. KeyboardKit has tools for customizing everything from keys, key behavior, layout, callout actions, audio & haptic feedback, colors and styling, autocomplete etc. The KeyboardKit app let you create keyboards directly on your iPhone and iPad. -

KeychainAccess
Simple Swift wrapper for Keychain that works on iOS, watchOS, tvOS
KeychainAccess is a simple Swift wrapper for Keychain that works on iOS and OS X. Makes using Keychain APIs extremely easy and much more palatable to use in Swift. If you want to store the Touch ID protected Keychain item, specify accessibility and authenticationPolicy attributes. Do not run in the main thread if there is a possibility that the item you are trying to add already exists, and protected. Because updating protected items requires authentication. Additionally, you want to show custom authentication prompt message when updating, specify an authenticationPrompt attribute. If the item not protected, the authenticationPrompt parameter just be ignored. The same way as when you get a normal item. It will be displayed automatically Touch ID or passcode authentication If the item you try to get is protected. The same way as when you remove a normal item. There is no way to show Touch ID or passcode authentication when removing Keychain items. -

Bagel
A little native network debugging tool for iOS
Bagel is a little native iOS network debugger. It's not a proxy debugger so you don't have to mess around with certificates, proxy settings etc. As long as your iOS devices and your Mac are in the same network, you can view the network traffic of your apps separated by the devices or simulators. Most basic usage is to start Bagel iOS before any network operation. Since Bagel exposes every request info to the public it would be better if you disable it for the store versions. By default, Bagel gets your project name and device information. The desktop client uses this information to separate projects and devices. You can configure these if you wish. Bagel framework communicates with the desktop client by using Bonjour protocol. You can also configure these Netservice parameters. -

Venice
Coroutines, structured concurrency and CSP for Swift on Mac and Linux
Coroutines, structured concurrency, and CSP for Swift on macOS and Linux. You can use Venice in multi-threaded programs. However, individual threads are strictly separated. You may think of each thread as a separate process. In particular, a coroutine created in a thread will be executed in that same thread, and it will never migrate to a different one. -

Connectivity
Makes Internet connectivity detection more robust by detecting Wi-FI
Connectivity is a wrapper for Apple's Reachability providing a reliable measure of whether Internet connectivity is available where Reachability alone can only indicate whether an interface is available that might allow a connection. Connectivity's objective is to solve the captive portal problem whereby an iOS device is connected to a WiFi network lacking Internet connectivity. Such situations are commonplace and may occur for example when connecting to a public WiFi network which requires the user to register before use. Connectivity can detect such situations enabling you to react accordingly. -
