CoderFlow
CoderFlow puts several AI agents to work on the same IBM i coding task, then keeps the result that actually compiles and passes tests. Built by Profound Logic for RPG, COBOL and CL, it writes, compiles, tests and fixes code instead of only suggesting it.
How CoderFlow works
- RaceSeveral AI agents work the same task at once, such as turning an RPG III subprocedure into free-format RPG IV.
- CompileThey compile with the real IBM i compilers over SSH.
- TestThey run 5250 terminal flows and Rich Display Files to test the result.
- Keep the winnerWork that compiles, passes tests and behaves as expected wins. Plain generated text is not the finish line.
It also plugs into Git and CI/CD pipelines.
The productivity claim
Productivity gain, times the starting speed
CEO Alex Roytman's stated aim against roughly 20 percent from typical copilots. A target, not a measured result.
What leaves your network
Profound Logic says only limited code snippets go to the cloud model. Full repositories and credentials stay home. Builds, tests and checks run on premises or in a private cloud.
