API-first validation and browser extension validation are not competing ideas. They are two operating modes for different points in the workflow.

Figure caption: MakeReliable supports both API pipeline validation and browser-based validation through the same engine.
When API-first is the better fit
API-first validation is strongest when teams need:
- repeatable pipeline checks
- automation at scale
- structured output for systems and reporting
It is the better fit for high-volume launch operations.
When browser extension validation is useful
Browser-based validation is strongest when teams need:
- instant in-context review
- manual checks on live pages
- guided fixes while inspecting the page itself
It is useful for reviewers and operators working directly in the browser.
