What people warn about
Each mark is one comment
Frequent breaking changes between releases
“The breaking Rendering changes have always been the big challenge”
Comment from 9 Oct 2026 in “Bevy 0.20” “They have been introducing breaking changes left and right”
Comment from 9 Oct 2026 in “Bevy 0.20” “The 0.2 version number would typically imply that breaking changes are to be expected and that it’s not ready for commercial projects”
Comment from 9 Oct 2026 in “Bevy 0.20” - Comment from 12 Feb 2026 in “Toyota Fluorite: "console-grade" Flutter game engine”
Slow compile times hinder iteration
“Bevy gives you a very nice ECS to model your app but compilation can be slower than hand crafted code”
Comment from 11 Apr 2026 in “Bevy game development tutorials and in-depth resources” “The one other downfall of this might be the fact that the compile times make iteration difficult.”
Comment from 9 Sep 2026 in “Animation in Bevy: The Big Picture” “even medium-scale game engines like Bevy take a bunch of time and space to compile”
Comment from 22 Mar 2026 in “The Three Pillars of JavaScript Bloat” Editor and tooling underdeveloped
“In some areas it is quite advanced (rendering) and in others it is lacking / underdeveloped (editors / tooling).”
Comment from 9 Feb 2026 in “Art of Roads in Games” “For Bevy to catch up on the indie game scene it needs an editor plus a scripting language”

“People say binaries start at 50 MB for a hello world program and 700 MB for the debug binaries.”
Comment from 11 Apr 2026 in “Bevy game development tutorials and in-depth resources” “has no reason to bloat binaries to be 50MB for an empty program that does nothing”
