Platform Comparison

This table describes the current Uzumibi templates. It does not attempt to reproduce provider pricing or runtime limits, which change independently of Uzumibi.

“Optional service APIs” means APIs implemented by that template’s adapter. Identical Ruby class names on different platforms can map to different provider services and are not a promise of full portability.

For provider limits and availability, consult the provider’s current documentation.
