    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.

    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.

    pwndbg

    Exploit Development and Reverse Engineering with GDB Made Easy

    Pwndbg is a fast, simple and lightweight tool for modern debugging. It improves debugging experience with the strength of GDB for low-level software developers, hardware hackers, reverse engineers, and exploit developers. It provides features crucial for efficient debugging in the world of low-level programming. Vanilla GDB is terrible to use for reverse engineering and exploit development. Typing x/g30x $esp is not fun, and does not confer much information. The year is 2024 and GDB still lacks a real hexdump command! GDB's syntax is arcane and difficult to approach. Windbg users are completely lost when they occasionally need to bump into GDB.

    Semgrep

    Lightweight static analysis for many languages

    Static analysis at ludicrous speed. Find bugs and enforce code standards. Find and prevent security issues in Terraform, Docker, Kubernetes, nginx, and AWS configs before they go into production. Go beyond application code and protect the entire stack with a breadth of scanning capabilities. Don't leak secrets, scan every commit and ensure secrets don't make it to production. Protect the privileged CI/CD environment from malicious activity that could result in access to source code, secrets, and more. Run with registry rules or your own. Code is analyzed locally (not uploaded). Get results at ludicrous speed with diff-aware scans, review findings in MR and PR comments, and deploy Semgrep across your organization’s projects. Go beyond the registry with rules specific to your organization. Write rules to enforce your own code guardrails.

    scanmem is a debugging utility designed to isolate the address of an arbitrary variable in an executing process. scanmem simply needs to be told the pid of the process and the value of the variable at several different times. After several scans of the process, scanmem isolates the position of the variable and allows you to modify its value.

    Continuously assess cloud security posture by flagging misconfigurations and suspicious activity. Consolidate container and host scanning in a single workflow. Automate scanning locally in your CI/CD tools without images leaving your environment and block vulnerabilities pre-deployment. Visualize all network communication across apps and services. Apply microsegmentation by automating Kubernetes-native network policies. Unify threat detection and incident response across containers, Kubernetes, and cloud with out-of-the-box Falco rules leveraging syscalls, Kubernetes audit logs and cloud logs. Gain deep insight with container and Kubernetes monitoring that is fully Prometheus compatible. Validate compliance against standards like PCI, NIST and SOC2 for containers, hosts, Kubernetes and cloud. Sysdig created Falco, the open standard for runtime threat detection for containers, hosts, Kubernetes and cloud.

    Cthulhu.jl

    Cthulhu.jl

    The slow descent into madness

    Cthulhu.jl is a powerful introspection tool for exploring the Julia compiler’s method dispatch and type inference system. It allows users to interactively descend into the type-inferred lowered and LLVM IR of Julia functions from the REPL. This makes it ideal for developers who want to optimize performance, debug type instability, or understand how Julia compiles code. Named after the Lovecraftian idea of descending into madness, Cthulhu reveals the "underworld" of Julia compilation.
