O3DE vs Buildbox
The short version
- Each has a real cost: O3DE minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2; Buildbox buildbox splits its editor into two separate paid product lines, Buildbox Classic and Buildbox 3, priced and sold as different products rather than tiers of one app (archived pricing page, 8 March 2026)
- They diverge on capability: O3DE covers 3D graphics rendering, Buildbox covers Visual game builder.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
O3DE
- Minimum hardware is a quad-core 2.5 GHz x86 CPU with SSE 4.1, 16 GB RAM and a DirectX 12 or Vulkan GPU with 2 GB VRAM and Shader Model 6.2
- Raytracing features require Shader Model 6.3
- Disk space required is 40 GB using the prebuilt installer and 100 GB or more when building from source
- Building the engine from source needs 2 GB of RAM per build thread on top of normal system requirements
- On Windows the editor requires Windows 10 version 20H2 or later plus Visual Studio 2019 16.11.x, 2022 17.3.x or 2026 18.0.x with the Game development with C++ workload
- The only primary Linux distribution for the editor is Ubuntu 22.04 LTS, and Ubuntu on 64-bit ARMv8 is experimental
- Linux builds need CMake 3.30.0 or later, which is newer than the 3.22 shipped by default with Ubuntu 22.04
- Wayland support is experimental, requires building from source, and is limited to the Game Launcher with no editor support until O3DE moves to Qt6
- Linux requires a long list of additional apt library packages to be installed before building
Buildbox
- Buildbox splits its editor into two separate paid product lines, Buildbox Classic and Buildbox 3, priced and sold as different products rather than tiers of one app (archived pricing page, 8 March 2026)
- Buildbox Classic Plus is $57.99 USD per year and Buildbox Classic Pro is $137.99 USD per year; Buildbox 3 Plus is $97.99 USD per year and Buildbox 3 Pro is $297.99 USD per year, with a companion audio tool Soundbox sold separately at $49.99 USD per year (archived pricing page, 8 March 2026)
- The only bundle combining Buildbox 3 Pro, Buildbox Classic Pro, and Soundbox is a separate $447.99 USD per year Ultimate Bundle rather than a natural upgrade path (archived pricing page, 8 March 2026)
