cohesion-app helps you see how parts of software talk to each other. It shows the rules that control how the user interface, backend services, and running system work together. This tool points out when these parts do not match up. It makes it easier to find and fix problems that happen when software pieces disagree.
You do not need to have programming skills to use cohesion-app. It is designed to help anyone check if a system’s services follow the same rules. You will find it useful if you want to understand how data moves between apps or check that changes to one part of a system will not cause problems elsewhere.

API contracts define how two parts of a system agree to communicate. They set rules about data formats, endpoints, and expected responses.
cohesion-app helps by showing you:
- What the front end expects from the backend.
- What the backend actually sends.
- Where the real-time system differs from planned rules.
If these three do not match, apps can break or deliver wrong information. The tool highlights these mismatches so you can fix issues before they cause problems.
