WebTransport Compatibility Lab
Check connection setup, streams, datagrams, lifecycle behavior, workers, HTTP/3 robustness, and optional HTTP/2 fallback.
Test setup
Choose the server, coverage level, and timing for this run.

Result identity
These labels group the anonymous result. They do not change the browser or WebTransport connection.
Raw user agent, IP, errors, and target URLs are not retained.
Current browser
Detected API surface and the identity that will accompany a published result.
Coverage
Each case combines one server response profile with one constructor option combination.
Server response profiles
Different successful CONNECT response shapes sent by the test server.
Constructor option coverage
Loading constructor coverage.

Result summary
How far the browser progressed and which echo features completed.
Current-draft coverage
Focused Web API, lifecycle, worker, HTTP/3, and optional HTTP/2 checks run once after the comparable option matrix. Not-run checks are lab coverage gaps, not browser failures.
