What is an API Workflow?

An API workflow represents the sequence of steps an API takes to process a request. Visualizing this helps in understanding logic, debugging issues, and communicating designs to stakeholders.

Why Use a Visual API Designer?

Modern application development often involves complex logic that can be hard to visualize in code alone. Our API Workflow Designer bridges the gap between abstract logic and concrete implementation. By providing a visual canvas, we help teams align on requirements, identify potential bottlenecks early, and document their architecture effectively.

Whether you are building microservices, designing serverless functions, or just planning a simple REST API, having a visual reference is invaluable. This tool runs entirely in your browser, ensuring your data remains private and secure while giving you the performance of a native application.
