Ultra-lightweight, fast debugger for Linux

Features

• Linux-only, ultra-lightweight, fast debugger inspired by RemedyBG, implemented directly in Rust without depending on gdb or lldb
• Fast responsiveness and a TUI-based UI let it handle even large executables (e.g., 2.5GB ClickHouse) without trouble
  • Time-consuming operations such as loading/searching are asynchronous/multithreaded and cancellable, with progress display
• Distributed as a single 6MB executable with no installation and no dependencies
• Limitations: Linux x86_64 only, TUI only, no remote debugging, fork tracing, or record/replay, no support for VM-based languages such as Java/Python

Key features

• Breakpoints / conditional breakpoints
• Step-by-step execution, code/assembly display
• Watch expressions, standard library pretty-printer support
• vtable-based downcasting
