TikTok Mini Game Debugging Guide Released
TikTok for Developers publishes a detailed guide for debugging Mini Games using DevTool (ttmg CLI). The documentation explains prerequisites (Node.js >= v20, Google Chrome, TikTok app, test users, single Wi‑Fi network), how to install and log in to the DevTool (npm install @ttmg/cli -g; ttmg login), and how to start a local debug session (ttmg dev). It describes pre-compilation checks, package size limits (total ≤30 MB; main package ≤4 MB; independent subpackage ≤4 MB), two debug modes (mobile device with in‑app vConsole and remote browser using Chrome DevTools), QR-code scanning flow, domain allowlisting, ad and payment mock debugging modes, custom startup packages and launch parameter handling (TTMinis.game.getLaunchOptionsSync), and how to upload debugged code packages to the Developer Portal for preview and release.
Provides developer tooling and operational guidance that streamlines Mini Game debugging, packaging and monetization readiness on TikTok, which can increase quality and throughput of in‑app games and associated ad inventory.

Key Takeaways & Evidence Grounding
- TikTok provides a local debug tool (DevTool, packaged as @ttmg/cli) installed via npm install @ttmg/cli -g; running ttmg dev starts a local debugging environment.
- DevTool requires Node.js v20+ and Google Chrome; developers must complete ttmg login locally for full functionality.
- Local debugging prerequisites include: TikTok app installed, test users registered on the Developer Portal, and mobile phone and computer on the same Wi‑Fi network.
- Mini game package size limits: total project source files ≤30 MB; main package ≤4 MB; each independent subpackage ≤4 MB (violations will block platform deployment).
- Debug modes: Mobile device mode (logic runs on device, uses in‑app vConsole) and Remote browser mode (logic runs in Chrome on PC, supports breakpoints and DevTools); ad and payment mock debugging options are available.

TikTok Minis: Debugging and Packaging Guide
TikTok's developer documentation provides step-by-step guidance for debugging, packaging, previewing and releasing TikTok Minis (mini-apps) locally and on the TikTok platform. It covers environment requirements (same local Wi‑Fi and external internet access), registering up to 30 test users via the Developer Portal, verifying SDK initialization with TTMinis.init and matching clientKey, creating a minis.config.json for dev/build settings, and using CLI commands (minis dev, minis build) to run local sessions and prepare production artifacts. The page also describes previewing via a generated QR code, injecting vConsole for on-device logs, recommended build integration (chain minis build after your build command), and links to related APIs (Monetization, Commercial Content API, Webhooks, Login/Share Kits and more).
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.
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.
