Our take
Where IBM API Connect leads
- Stronger evidenced coverage on 12 of the 27 capabilities where they differ (led by self-service developer portal and app registration & subscriptions).
Where Postman leads
- Stronger evidenced coverage on 15 of the 27 capabilities where they differ (led by mock servers / sandboxes and uptime / synthetic monitoring).
- Published pricing where the alternative quotes.
Where they differ
The 27 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.
