Where Kong leads
- Stronger evidenced coverage on 20 of the 29 capabilities where they differ (led by rate limiting & quota enforcement and load balancing).
- Published pricing where the alternative quotes.
Where they differ
The 29 capabilities (of 47 in the API management taxonomy) where the evidence separates them, biggest gaps first. “Not evidenced” means our research found no public documentation of this capability — the vendor may still offer it. Confirm on a demo.
