FusionDebug is a certified debugger for Railo and lets you see what's happening in your application as each line of code is being executed. It can be used to set breakpoints, step over, into, or out of code, inspect variables (across different scopes), and watch expressions. FusionDebug integrates with the Eclipse™ IDE and is an essential tool for anyone who is serious about developing in CFML.
- Debug With No Code Changes
- Debug Without Output Statements
- Filter Breakpoints By IP Address (Non-Intrusive Debugging)

Increase your ColdFusion development team's productivity with advanced CFML debugging! FusionDebug, the interactive step debugger for ColdFusion, now supports IP Filtering. This allows breakpoints to only fire when requests are coming from a specified IP address. This makes it possible for a ColdFusion developer to debug and set breakpoints against a central ColdFusion server, leaving the system untouched and unaffected for everyone else while you debug.
