+# Building Native Images
+
+Building native images with Akka HTTP is supported out of the box for the event sourced journal, snapshot store and 
+durable state store and databases:
+
+* H2 (inmem and file)
+* Postgres
+
+Other databases can likely be used but will require figuring out and adding additional native-image metadata.
+
+For details about building native images with Akka in general, see the @extref[Akka Documentation](akka:additional/native-image.html).
