Match the deployment platform
Check whether the tool fits your setup. Available deployment choices include web, API, macOS, Linux, Windows and self-hosted environments.
Axway Amplify Engage lists API, self-hosted and web availability. Cortex is listed for API and web, while Gravitee Developer Portal, Salt Security API Inventory and StackSpot API Catalog list web deployment.
Check catalog and governance work
Compare catalog sources and how ownership assignment works. Examine the governance workflows before selecting a tool for service or API oversight.
Look for the workflow controls your organization needs, rather than assuming a catalog or portal covers the same process across tools.
Review portal access
Portal access shapes how developers locate and use API information. Compare the portal features listed for the tool with the way your users need to reach catalog entries.
API catalog tools can pair catalog records with portal access, but the available setup depends on the product and deployment model.
Check API formats and deployment
Compare supported API specification formats and the deployment options that matter to your environment. Confirm whether web, API or self-hosted access is required.
If code reading or modification is part of your use, review the tool's licence before adoption.
