Play the recording: Navigating the Gateway API Maze: 40+ Implementations, 55+ Features, and a Path to Portability

  • Why: The honest counterweight to the previous talk. "Use Gateway API" is not a decision; 40+ implementations and 55+ features is a procurement problem, and feature support varies enough that portability is a claim worth testing.
  • What: Tooling and a method for picking an implementation, plus what "supports a feature" actually guarantees.
  • How: A new set of tools to discover and compare implementations by feature name, and an examination of how the conformance test suite underwrites portability — including how to tell whether features you already depend on are genuinely supported by your implementation.
  • Where applicable: Directly useful to anyone selecting or auditing a Gateway API implementation. Vendor-neutral by construction, though both speakers work for implementers.
