Delve vs Erlang Debugger

Delve has no write-up on Specifiction yet; its figures are above.

Erlang Debugger is a graphical interface for debugging and testing Erlang programs. Developers can set line, conditional, and function breakpoints, then attach to a process to step, continue, finish, skip, or stop its execution. The Attach Process window displays variable bindings and allows editing values when they can be represented in the running system. A Monitor window shows interpreted modules and information about processes running interpreted code. Debugger can record interpreted function calls for stack navigation, though recording tail calls uses more memory and can slow execution when many tail-recursive calls are involved. Modules need debug information, for example from compilation with `erlc +debug_info`. Global mode can interpret code on known nodes and display their processes, but the documentation warns that using global mode on multiple network nodes can cause interference. The debugger is listed for Linux, macOS, and Windows, and Erlang/OTP releases from version 18.0 onward use the Apache License 2.0. Debugging has runtime tradeoffs: interpreted code runs slower, each debugged process adds a meta process, and timers or tracing may behave differently.
