nvim-dap

Implements the entire Debug Adapter Protocol, enabling cross-language debugging with advanced features like breakpoints with conditions and logpoints, as detailed in the key features list.

Acts as a DAP client library, allowing community plugins to extend UI and functionality, which is a core part of its philosophy and non-goals section, fostering a rich ecosystem.

Prioritizes workflow within Neovim with keymaps, built-in REPL, and widget UI, making debugging feel native, as shown in the usage section with commands like :DapContinue.

Supports operations like step back and reverse continue, which are not common in basic debuggers, listed in the features as part of core functionality.
