Byte Buddy is a runtime code generation and bytecode manipulation library for Java. It provides a fluent API for creating and modifying Java classes during execution, enabling developers to define class structures, methods, and fields programmatically without requiring a compiler or direct bytecode assembly. The library supports agent-based class transformation, allowing loaded classes to be modified during JVM startup or runtime through a Java agent that intercepts class loading. It offers bytecode-level method interception for fine-grained control over method behavior, annotation-based code

Seer is a graphical frontend for GDB that provides a visual interface for inspecting variables, managing breakpoints, and stepping through code. It functions as a low-level debugger visualizer with specialized tools for call stack inspection and register visualization. The project distinguishes itself by integrating low-level program analysis directly into the visual experience, featuring a synchronized assembly overlay that maps CPU registers and assembly instructions to source code lines. It also includes memory bug detection capabilities by randomizing the program starting address during t

Ben.Demystifier is a .NET library that transforms raw stack traces into modern C# 7+ syntax. It reads compiler-generated frames produced by async methods, iterators, lambdas, local functions, and generic types, then rewrites them to match the original source code, making exception call stacks and debug output immediately readable. The library resolves common compiler artifacts such as MoveNext frames back into their original async method or iterator names, shows declaring method names and ordinals for lambdas and local functions instead of generated identifiers, and displays resolved generi

errors is a Go error handling library and stack trace utility that wraps standard errors with execution call stacks and contextual information. It captures program execution paths at the exact moment an error is initialized, extracting granular file paths, line numbers, and function symbols from raw program counter addresses. The library maintains parent-child relationships between wrapped errors to allow deep inspection, unwrapping of root causes, and combination of multiple errors into unified structures. It implements standard error interfaces so enhanced error objects can be used intercha
