    Flipper

    Flipper

    A desktop debugging platform for mobile developers

    Flipper is a platform for debugging iOS, Android and React Native apps. Visualize, inspect, and control your apps from a simple desktop interface. Use Flipper as is or extend it using the plugin API. Flipper aims to be your number one companion for mobile app development on iOS and Android. Therefore, we provide a bunch of useful tools including a log viewer, interactive layout inspector, and network inspector. Flipper is built as a platform. In addition to using the tools already included, you can create your own plugins to visualize and debug data from your mobile apps. Flipper takes care of sending data back and forth, calling functions, and listening for events on the mobile app. Both Flipper's desktop app and native mobile SDKs are open-source and MIT licensed. This enables you to see and understand how we are building plugins, and of course join the community and help improve Flipper. We are excited to see what you will build on this platform.

    rr

    rr

    Record and Replay Framework

    rr aspires to be your primary C/C++ debugging tool for Linux, replacing — well, enhancing — gdb. You record a failure once, then debug the recording, deterministically, as many times as you want. The same execution is replayed every time. rr also provides efficient reverse execution under gdb. Set breakpoints and data watchpoints and quickly reverse-execute to where they were hit. rr works on real applications and is used by many developers to fix real bugs. It makes debugging hard bugs much easier, but also speeds up debugging of easy bugs.

    RenderDoc

    RenderDoc

    RenderDoc is a stand-alone graphics debugging tool

    RenderDoc is a free MIT licensed stand-alone graphics debugger that allows quick and easy single-frame capture and detailed introspection of any application using Vulkan, D3D11, OpenGL & OpenGL ES or D3D12 across Windows 7 - 10, Linux, Android, Stadia, or Nintendo Switch™. I work on RenderDoc myself and you can always contact me with any problems or comments. I'll respond to you directly and personally, and I'm used to helping people with private or NDA'd projects. RenderDoc is 100% open source and development all happens on github. Check out the source and see how any feature is implemented, report a bug you've found, or request a new feature or improvement. Usability matters. Tools should have a low barrier to entry and be easy to use and understand. RenderDoc makes the process of getting started as smooth as possible, and simplifies common workflows. Support is distributed separately for authorized developers as part of the NintendoSDK.

    SpoofMAC

    SpoofMAC

    Change your MAC address for debugging

    SpoofMAC is a command-line utility for changing and restoring MAC addresses on network interfaces in Linux and macOS systems. The project allows users to randomize or manually configure MAC addresses to improve privacy, testing flexibility, or network anonymity in various environments. It automates low-level networking commands and provides a user-friendly interface for managing interface states and address changes safely. SpoofMAC is commonly used for privacy protection on public networks, penetration testing workflows, and network simulation environments where MAC address manipulation is required. The tool also supports restoring the original hardware MAC address and handling multiple network interfaces efficiently. Its lightweight design and straightforward command-line usage make it popular among system administrators, developers, and security researchers.

    git-bug

    git-bug

    Distributed, offline-first bug tracker embedded in git, with bridges

    git-bug is fully embedded in git, you only need your git repository to have a bug tracker. git-bug is distributed. Use your normal git remote to collaborate, push and pull your bugs! git-bug works offline, in a plane or under the sea? Keep reading and writing bugs! It prevents vendor lock-in: your usual service is down or went bad? You already have a full backup. It is fast, listing bugs or opening them is a matter of milliseconds. git-bug doesn't pollute your project, no files are added in your project. git-bug integrates with your tooling, use the UI you like (CLI, terminal, web) or integrate with your existing tools through the CLI or the GraphQL API. git-bug bridges to other bug trackers. Use bridges to import and export to other trackers. An interactive terminal UI is available using the command git bug termui to browse and edit bugs.

    Bot Framework Emulator

    Bot Framework Emulator

    Locally test and debug chat bots built with the Bot Framework SDK

    Bot Framework Emulator is a desktop application that allows bot developers to test and debug bots, either locally or remotely. Using the Emulator, you can chat with your bot and inspect the messages that your bot sends and receives. The Emulator displays messages as they would appear in a web chat UI and logs JSON requests and responses as you exchange messages with your bot. Before you deploy your bot to the cloud, run it locally and test it using the Emulator. You can test your bot using the Emulator even if you haven't yet created it with Azure Bot Service or configured it to run on any channels. Before connecting your bot to the Bot Framework Emulator, you need to run your bot locally. You can use Visual Studio or Visual Studio Code to run your bot, or use the command line. When you are developing behind a corporate proxy, the Emulator will use the configured environment variables HTTP_PROXY and HTTPS_PROXY, which specify the proxy URL route for HTTP and HTTPs requests.
