Frequently asked
Unity alternatives FAQ
- What changed with Unity's pricing?
- Unity announced a Runtime Fee in 2023 that would charge developers per install once certain revenue and install thresholds were met, which caused a major backlash. On 12 September 2024 Unity cancelled the Runtime Fee entirely and returned to seat-based subscription pricing, with pricing changes taking effect in 2025.
- Is Unity still charging the Runtime Fee?
- No. Unity cancelled the Runtime Fee for games in September 2024. The company returned to seat-based subscriptions, so you pay per editor seat rather than per game install. Unity Personal remains free for developers below the revenue threshold.
- What is the best Unity alternative?
- Godot is the best alternative for most teams leaving Unity because it is free, open source under the MIT licence and has no royalties or runtime fees. Unreal Engine is the strongest choice for high-fidelity 3D games, and Defold is a good fit for lightweight 2D and mobile titles.
- Is there a free Unity alternative with no royalties?
- Yes. Godot is free and open source under the MIT licence with no royalties and no revenue thresholds, and anything you build with it is entirely yours. Defold is also free forever, and Bevy and LÖVE are free and open source. Unreal Engine is free to start but charges a royalty above a revenue threshold.
- How hard is it to move a game from Unity to another engine?
- Moving engines is a significant project, not a quick swap. Scripts have to be rewritten in the new engine's language, scenes and prefabs need to be rebuilt, and any asset store packages you rely on may not exist elsewhere. Teams usually finish their current project in Unity and start the next one in the new engine.
