Unity Version Compatibility Checker
Pick your target platform and get a recommended Unity version, plus the gotchas to watch for.
Target platform
Mobile (iOS / Android)
Unity 6 LTS ships meaningful mobile build-size and startup-time improvements over 2022 LTS, and is required to target the newest Android/iOS SDK levels that the stores now enforce.
- Use the IL2CPP scripting backend — Mono is not accepted by the App Store and is being phased out on Google Play.
- Check your target Android API level against Google Play’s minimum (raised annually) before locking in an engine version.
- URP is the default render pipeline choice for mobile — HDRP is not supported on mobile GPUs.
WebGL
Unity 6 brought real WebGL improvements: smaller Brotli-compressed builds and better multithreading via WebAssembly. Worth upgrading for WebGL specifically even if you don’t need it elsewhere.
- Enable Brotli compression in Player Settings for the biggest single build-size win — estimate the difference here.
- Treat WebGPU as experimental — stick to the WebGL 2 backend for production builds.
- Test on Safari early; it historically lags Chrome/Firefox on WebGL feature support.
Console (PlayStation / Xbox / Switch)
Console SDKs and certification requirements lag behind the newest Unity release. Don’t assume the latest Unity 6 LTS is certified for your target platform’s dev kit yet.
- Check with your platform holder / publisher which Unity versions are currently certified before committing.
- 2022 LTS has been the widely-certified baseline, but it is at the end of its support window — plan an upgrade path to a certified 6000.x release.
- Budget extra QA time for any engine upgrade mid-project — console cert testing is expensive to repeat.
VR / AR
Unity 6 LTS has the most current OpenXR plugin support, which is what you want for Meta Quest, SteamVR, and most modern XR headsets.
- Use the OpenXR plugin over the legacy XR SDKs — they’re deprecated and losing support.
- Quest devices require a specific minimum Android API level — check Meta’s developer docs before picking your Player Settings target.
- Target the headset’s native refresh rate (72–120 Hz) — see our performance budget calculator.
Desktop (Windows / Mac / Linux)
Desktop has the fewest constraints — the current Unity 6 LTS is the safe default unless a specific asset or plugin you depend on hasn’t updated yet.
- HDRP is a real option here if you want high-fidelity visuals and can target dedicated GPUs.
- Check third-party Asset Store plugins for Unity 6 compatibility before upgrading an existing project.
- Apple Silicon (M-series) builds are fully supported — no Rosetta needed on recent Unity versions.
Rule of thumb for any platform: start new projects on the newest LTS, and don’t upgrade a shipping project mid-cycle without a full regression pass. Unity’s LTS release page lists which 6000.x stream is current.
📦 Check your assets before you upgrade
Asset Store packages that lag behind the current LTS are the most common source of post-upgrade compile errors. Our Asset Store roundup includes buying tips for checking version support before you pay.
