This is free and open source software.
Key Features
- Fast.
- TUI.
- Not based on gdb or lldb, implemented mostly from scratch.
- Works on large executables.
- Most standard debugger features are present e.g. breakpoints, conditional breakpoints, data breakpoints, stepping of all kinds, showing code and disassembly, watch expressions, built-in pretty-printers for most of C++ and Rust standard library.
- Many quality-of-life features are present (e.g. auto-downcasting abstract classes to concrete classes based on vtable).
