Impact Analysis Where Developers Live

Gable builds the field-flow graph from your code and surfaces the impact of code changes. You’ll see downstream effects and suggested fixes without hunting across repos.

SCAN

Find before you build

Too many similar fields and sources? Compare candidates side-by-side and pick the canonical one fast.

CONTROL

Ship with confidence

Unclear who to involve? Suggested reviewers and merge guidance reduce risk & finger-pointing.
