ReGrade™
Powered by patented NCAST technology
Field-level analysis that catches regressions in API behavior by comparing real traffic across software versions.
Features
Traffic Replay
Capture and replay real production traffic against your staging environment.
Differential Analysis
Automatically compare API responses between versions to identify regressions.
Use Cases
AI Agentic Coding & ReGrade MCP
ReGrade works in-the-loop with your AI coding agent, automatically replaying real traffic against new code and feeding results back so the LLM converges faster.
Automatic Merge Request Analysis
ReGrade replays recorded production traffic against every merge request, automatically surfacing behavioral and performance differences before code reaches production.
LLM Language Refactoring & ReGrade
When LLMs transform code between languages — C to Python and back — ReGrade uses field-level comparison to verify that every version behaves identically, so you can migrate to memory-safe languages with confidence.
