TOOLS/400

Nov 12, 2026 

 

Tools/400 is a private, non-commercial site for IBM i developers and system administrators that has been around since 1997. It was created by @Thomas Raddatz.

@Tools/400 is a collection of freeware for IBM i. It is the home of plug-ins for IBM Rational Developer for i, of the Peek/400 file editor and of many utilities and service programs for RPG and CL.

Tools/400 has been recently updated. I believe you will find many of these tools are invaluable and very helpful on the job.

 

Most tools were created by Thomas. Isphere and Rapid Fire were created by Frank Hildebrandt. Thomas developed them further. There is more detail on the Tools/400 "About" page.

All tools are free and open source. Sources, releases and issue trackers are on the GitHub Tools/400 Site.

Tools/400 can also be found on the IBM i Reference Pages Blog Vendor and Resources Page here. 

The main page looks like this:

  

 

 

If you use @Thomas' Tools/400 software, please give him a shout-out. He'd appreciate knowing that his software helped you on the job.
