TikTok Unity Mini-Game Packaging Optimization Guide
TikTok's developer documentation provides a Unity Packaging Optimization guide for TikTok Mini Games. The guide gives step-by-step best practices to reduce package size and improve load performance, covering texture compression (ASTC), graphics API configuration (WebGL 1/2), managed code and engine stripping, shader/variant reduction, compression of textures and audio, and packaged-product analysis. It also recommends disabling unused Unity packages/modules, setting specific player/publishing settings (e.g., external debug symbols, explicit exception handling), and using CDN/Addressables/AutoStreaming for large audio/video resources. The recommendations are intended to help developers meet TikTok package-size limits and improve startup and runtime behavior across mobile/WebGL targets.
Technical guidance from TikTok helps developers optimize mini-game performance and package size on a major social platform, which can affect user experience and monetization but is not industry-shifting.

Key Takeaways & Evidence Grounding
- TikTok published a Unity Packaging Optimization guide for TikTok Mini Games to reduce package size and improve load performance.
- The guide recommends using ASTC texture compression and setting Unity's Texture compression format to ASTC for mobile/WebGL targets.
- Developers are advised to uncheck Auto Graphics API and keep only WebGL 1 or WebGL 2 to reduce shader variants and startup time.
- Recommendations include setting Managed Strip Level to High, enabling Strip Engine Code, disabling unused Unity packages/modules, and reducing always-included shaders.
- For large audio/video assets the guide recommends using CDN delivery or Unity Addressables / AutoStreaming to lower packaged size and RAM usage.

TikTok Mini Games Technical Overview
TikTok's developer documentation describes the technical architecture, integration paths, build outputs, and debugging/upload flow for TikTok Mini Games — lightweight games that run inside the TikTok client rather than as standalone apps. Supported engines include Cocos, Unity and Laya; Unity projects compile C# via IL2CPP to WebAssembly. The guide details required package directory structures, strict package-size limits (different for Unity vs non‑Unity), runtime layers (game, platform capability, native runtime, client host), platform capability integration via built-in runtime APIs or the TikTok Unity SDK, and developer tooling (DevTool and @ttmg/cli) with remote, real-device and platform preview modes. It also notes Unity-specific constraints (client version >= 43.1.0, bulk memory and Wasm split guidance) and recommends following provided templates and DevTool pre-checks before submission.
TikTok releases Unity SDK for Mini Games
TikTok's developer documentation details the TikTok SDK for Unity, a client-side bridge that lets Unity-built mini games run inside TikTok’s mini app environment and access platform capabilities (startup, login, payments, sharing, ads, storage, device features). The guide lists requirements (TikTok client v4310+, Unity 2021/2022, package size <= 60 MB), recommends the com.tiktok.minigame@1.0.1 release (fixes TTAssetBundle loading), and explains build, local debugging, and upload flows (CLI recommended). The documentation also links to related TikTok Minis, monetization, analytics, and packaging-optimization resources for developers preparing and publishing mini games on TikTok.
TikTok Mini Games: Developer Troubleshooting Guide
This is TikTok's developer troubleshooting guide for Mini Games, detailing debugging workflows, required account and platform configurations, capability integrations, payment/IAP handling, and platform preview diagnostics. It explains CLI commands (ttmg login, ttmg dev), test user and Client Key setup, domain whitelists, package/subpackage rules, Unity-specific requirements, OAuth/token exchange flows (frontend gets code, backend exchanges via Open API), IAP sandboxing and Webhook handling, and API/version compatibility checks using TTMinis.game.canIUse. The document provides ordered troubleshooting steps, escalation triggers, required diagnostic data to collect, and recommendations for remote debugging, real device preview, and platform preview scenarios.
