BCC is an eBPF development toolkit and tracing framework used for monitoring and analyzing the Linux kernel. It functions as a performance analysis tool and debugging utility to capture system events, measure kernel latency, and provide network observability. The project distinguishes itself by providing a build system that integrates with LLVM to compile C-like code into BPF bytecode at runtime. It utilizes BPF Type Format data for relocations to maintain cross-kernel compatibility and extracts kernel headers to ensure the generated programs match the specific kernel version. The toolkit co

Pinpoint is a distributed application performance management tool designed to trace requests and monitor metrics across large-scale distributed architectures. It functions as a request tracer, topology mapper, and JVM application monitor, providing a backend capable of collecting and visualizing trace data from OpenTelemetry compatible sources. The system distinguishes itself through a combination of bytecode-based instrumentation via a Java agent and topology-based visualization that renders live maps of service interconnections. It captures execution flow across asynchronous boundaries, suc

Wuzz is an interactive command line HTTP client and request inspector designed for capturing, reviewing, and analyzing outgoing network calls and their payloads. It functions as a terminal-based tool for debugging API issues and testing web endpoints. The tool provides specialized filtering for response bodies, using regular expressions and format-specific query syntaxes tailored for JSON and HTML data. It allows for the persistence of captured requests and responses to disk to facilitate the reproduction of network issues and offline analysis. User settings and default request behaviors are

httpstat is a command-line utility for executing HTTP requests and analyzing network timing, response metadata, and connection performance. It serves as a diagnostic tool and debugger for inspecting HTTP headers and response bodies through a terminal interface. The tool focuses on performance analysis by measuring the latency of secure web requests, including the overhead of the TLS handshake and general connection timing. It provides color-coded output to visually separate request and response metadata for human analysis. The utility covers API integration testing and network troubleshootin

Helicone is an AI gateway and observability platform designed to intercept, manage, and monitor interactions with large language models. By acting as a reverse-proxy, it provides a centralized layer for routing requests across multiple AI providers, allowing developers to maintain consistent application logic while gaining deep visibility into model performance, usage, and costs. The platform distinguishes itself through a robust suite of traffic management and prompt engineering tools. It enables policy-driven control, including automatic failover between providers, rate limiting, and edge-b

FeHelper ist eine Toolbox für Webbrowser-Erweiterungen und ein Frontend-Entwicklungs-Toolkit, das in Chrome, Firefox und Edge integriert ist. Es dient als Dienstprogramm zur Datentransformation, als Tool zum Debuggen von Webseiten und als KI-gestützter Coding-Assistent.
