AsyncAPI Companion
FreeAsyncAPI Tooling
Reliable go-to-definition for $ref values in AsyncAPI documents (JSON and YAML): 100% local, no network calls, and it never breaks when a new JetBrains IDE version ships.
The gap it fixes
Born from real evidence in JetBrains Marketplace reviews, not assumptions: the leading AsyncAPI plugin in this space (FREEMIUM, actively developed) has 55% of its reviews at 3 stars or fewer — higher than the negative-review rate that anchored several other plugins in this catalog. Paying and free users alike report:
- "Suddenly no longer works in PyCharm. Says the java plugin is required." — breaks on a routine update, no code change on the user's end.
- "Does not work with IntelliJ 2024.2.4. The install does not complete and just reverts back to not being installed without any errors or error messages."
- "I'm getting error when I try to load the preview. I'm getting blank white screen with this: Error: The asyncapi field is missing. I have a valid asyncapi.yaml file." — a real bug, not user error.
Re-verified 2026-09-23: still 55% (11/20), same reviews, unchanged. Worth noting honestly: that competitor shipped a full rewrite of its own $ref resolution engine in 2026-08 (after the most recent review above), including free cross-format resolution — which is why this plugin added the same capability in 0.3.0. All three cited reviews predate that rewrite, and this plugin makes no claim about whether it fixed them.
