Open Source Swift Security Software for Mac

Safe Exam Browser is a webbrowser-environment to carry out online-exams safely. The software changes any computer into a secure workstation. It regulates the access to any utilities and prevents students from using unauthorised resources.

In a society that is increasingly determined to weaken that right, a fast, reliable and easy-to-use VPN connection is a good first step towards achieving this. By connecting to the Internet with Mullvad, we ensure that traffic to and from your device is encrypted to the highest standards, even when using public Wi-Fi in a coffee shop or hotel. We do not keep activity logs or ask for personal information, and we even encourage anonymous payments using cash or any of the accepted cryptocurrencies. Your IP address will be replaced with one of ours, ensuring that device activity and location are not linked to your user. Using Mullvad is quick and easy - just download and install the app. Don't spend time on complicated setup and multi-step registration processes. We designed Mullvad to be easy to use. Privacy is essential in a well-functioning society, as it allows norms, ethics and laws to be safely debated and challenged. Without privacy, a free and open society cannot flourish or exist.

ShadowsocksX-NG is the new ShadowsocksX, a secure socks5 proxy for accessing restricted sites or services on macOS. ShadowsocksX-NG was created separately from the original implementation as there had been too much unused code and dependencies of the ss-local source code in the original that had to be maintained. As such it was difficult to update. ShadowsocksX-NG has just a copy of ss-local from Homebrew, and its GUI code has been rewritten in Swift. It now runs as a background service rather than an in-app process, so the ss-local may still be running even after you quit the app. ShadowsocksX-NG also has an added manual mode so you can configure your apps to use the socks5 proxy manually without configuring the system proxy settings.

BLEUnlock is a small menu bar utility that locks and unlocks your Mac by proximity of your iPhone, Apple Watch, or any other Bluetooth low-energy device.

KeePassium is a password‐manager app for iOS and macOS that is fully compatible with the KeePass family of encrypted database files. It is open-source under GPLv3 yet offered as a polished commercial app, offering a blend of transparency and user-friendly design. Users retain full control of their password database location (cloud or local), while KeePassium handles smooth synchronization and secure access with Face ID/Touch ID or passcode. The app supports complex encryption standards, including AES, ChaCha20, Twofish and Argon2, and works with KDBX3, KDBX4, and KDB (KeePass 1.x) formats. Because it integrates with the iOS Files system, it supports many storage providers (iCloud Drive, Dropbox, OneDrive, SFTP, WebDAV) with minimal setup, making it flexible for personal, family or team use. Additional advanced features such as TOTP codes, YubiKey challenge-response, file attachments, custom fields and icons make it useful for power users.

The Apple Silicon Guide repository is a detailed resource for users adopting or migrating to Apple Silicon (M1/M2/Pro/Max/Ultra) Macs, offering a wealth of information on hardware capabilities, software compatibility, performance optimization, and tooling best practices. It covers differences between Apple Silicon and legacy Intel architectures, helping users understand how to choose software builds (arm64 vs. universal), deal with Rosetta 2 translation, and optimize workloads for native performance. The guide also includes practical advice on setting up development environments — such as configuring compilers, package managers, containers, virtualization tools (e.g., UTM/VMs) — and resolving common pain points with dependencies that historically lacked native support. For creative and power users, there are performance recommendations for video/audio production, machine learning workflows, and GPU-accelerated tasks.

Don't let cumbersome web debugging tools hold you back. With Proxyman's native macOS app, you can capture, inspect, and manipulate HTTP(s) traffic with ease.

Proxyman acts as a man-in-the-middle server that captures the traffic between your applications and SSL Web Server. With a built-in macOS setup, so you can inspect your HTTP/HTTPS Request and Responses in plain text with just one click. Narrow down your search with Proxyman's Multiple Filters. You can combine complex filtered criteria like Protocol, Content-Type, URL, Request Header, Response Header, Body, etc that find exact what you're looking for.

Secretive is a macOS app that generates and stores SSH keys inside the Secure Enclave, keeping private keys non-exportable and bound to your hardware. It runs an ssh-agent compatible service, so existing tools can use the keys without any changes to your workflows. Because the keys never leave the Secure Enclave, even root on the host cannot read them, which raises the bar against credential theft. A simple menu-bar interface lets you create, label, and manage keys, prompt for authorization, and control which processes may request signatures. The design favors least privilege and auditability: you explicitly approve usage and can revoke access without having to hunt for files on disk. For developers, admins, and security-conscious users, Secretive provides a clean way to upgrade SSH hygiene with hardware-backed protection and minimal friction.

Soft U2F is a software U2F authenticator for macOS. It emulates a hardware U2F HID device and performs cryptographic operations using the macOS Keychain. This tool works with Google Chrome/Chromium, Safari, Firefox and Opera's built-in U2F implementations.

OmniEdge is an Open source p2p layer 2 , zero-config mesh VPN infrastructure, a traditional VPN, AWS VPC, Ngrok, DDNS alternative. No central server, easy to scale with less maintenance. What happens in intranet, stays in in intranet.
