Erlang Debugger vs UDE Universal Debug Engine

Both stand on debuggers. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Erlang Debugger

Paid LinuxMacWindows

Choose Erlang Debugger when you need a graphical way to test Erlang programs, inspect processes, or control execution with breakpoints. Look elsewhere if your debugging work depends on normal execution speed, code replacement, or timer behavior remaining unchanged.
