Each mark is one comment

  • Pleasant to learn and use

    “Overall, it's been a pleasure, and at the time of the 0.14->0.15 upgrade my codebase was small enough that it was done in an hour or so.”

    “Bevy was a really nice breath of fresh air when I dipped my toes back into hobby game dev”

    Comment from 9 Sep 2026 in “Animation in Bevy: The Big Picture”

    “I'm currently building a game with it right now and having a blast.”

    Comment from 14 Aug 2026 in “What You Gain by Building Your Own Game Engine”
  • ECS architecture is easy to reason about

    “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”

    “If you want to get inspired by good component DX, try looking at Bevy, the game engine.”

    Comment from 21 Jul 2026 in “Show HN: A self-running space economy SIM in Rust and Bevy”
  • Modular, use only needed parts

    “yes it's very well designed, and because if it's modularity it's well positioned both to support an editor”

    Comment from 9 Oct 2026 in “Bevy 0.20”

    “You can choose how much of the engine you use and just not import the parts you don't want.”

    Comment from 19 Apr 2026 in “Updating Gun Rocket through 10 years of Unity Engine”

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”
  • 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”

    Comment from 29 Sep 2026 in “Using any C++ library in Godot”
  • Large binary sizes

    “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”
