Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

jMonkeyEngine

  • jMonkeyEngine is a code-first Java library with no bundled editor; the engine itself ships no scene editor
  • The optional jMonkeyEngine SDK is a NetBeans-based tool maintained separately from the engine, so it lags the engine release cycle
  • Projects must be written in Java and wired up through Gradle, Maven or a hand-rolled build
  • Choosing the DIY route means providing your own build, source layout, editor, runtime packaging and workflow
  • Support runs through community Discussions and Discord rather than a vendor channel

Stencyl

  • The free Starter tier can publish to the web only
  • Desktop publishing requires the Indie plan at $99 a year
  • iOS and Android publishing require the Studio plan at $199 a year
  • Licences are annual, so continuing to publish means continuing to pay
