Where each one falls short

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

Construct 3

  • The free version caps projects at 50 events, or 25 when used without an account
  • Free projects are limited to 2 layers, 2 special effects, 1 timeline animation of up to 5 seconds and 1 web font
  • The free version can only publish to HTML5 and the Construct Arcade, so desktop, Android, iOS and Facebook Instant Games all need a paid plan
  • Licences are per seat and annual, at $129.99 for Personal, $168.99 for Startup Business and $468.99 for Business

Flax Engine

  • Flax charges a 4% royalty on game earnings above $250,000, assessed per calendar quarter
  • Free use is granted for non-commercial or educational usage; commercial releases fall under the royalty
  • Users must accept the Flax Engine End-User License Agreement before using the engine or its tools, so it is not an OSI open source licence despite the source being on GitHub
  • Non-game uses such as in-house tools or SaaS products need a custom licence negotiated with the vendor, and no rate card is published for per-seat or flat-fee options
