+# Compatibility

+%product% is **alpha-quality software**, meaning it has not yet reached a level of stability where correct operation is
+guaranteed or even typical.
+
+The language engines used by %product% are based on [GraalVM](https://graalvm.org)
+[Truffle](https://www.graalvm.org/latest/graalvm-as-a-platform/language-implementation-framework/). Truffle engines
+aren't necessarily compatible by default with their corresponding regular language engines.
+
+Refer to the table below for resources regarding compatibility in each language.
