You can start debugging your scripts immediately, no install or account necessary.
1) Open a console in to the machine where your script exists and runs.
2) Run 'curl -s https://debug.sh | bash -s -- <script.sh>' (replace <script.sh> with the filename of the script you want to debug).
3) A link to your live debugging session is provided in your terminal
4) Open the link in you favorite browser and from there you can run, step, add breakpoints, watch variables, view console output, etc.
That's it!* No installs, no downloads, no logins, free of charge!
*If your firewall does not allow outbound traffic you will need to whitelist our domain (edebug.sh)
