<li>No schema editor by default.

But it should be easy to add one using any editor that can run inside a browser.</li>
<li>It does have a <a href="https://github.com/graphql/graphiql" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">query editor</a></li>
<li>Compared to Amazon AppSync, there are no default resolvers are available. Developers have to write their own resolvers in javascript. See example <a href="https://github.com/wei-lee/apollo-example/blob/master/data/resolvers.js" class="external-link" rel="nofollow" style="color: #3b73af; text-decoration: none">here</a>. But it also means that developers can use what ever connectors to resolve the data. AppSync also has a nice UI to allow developers to easily create resolvers and implement simple resolvers using their own DSL.</li>

<ul>
<li>It also comes with a code generator that can generate typed classes from the schema definition for these languages: java, swift, typescript, scala. No c# support.</li>
<li>It has the following client SDKs: android, ios, javascript. No Xamarin SDK. All of them supports offline caching. It looks like the caching are backed by SQLite on the device. But it is pluggable.</li>
<li>Also all the client SDKs support subscription (using websockets) to achieve real-time</li>
