- Review process
- Strict. Content rules around politics, gambling, history, and minors are enforced at submission and post-launch. ICP filing required for the publishing entity. Game version number (版号) is a separate license, not always required for casual MiniApp games but increasingly checked.
- Runtime and limits
- Initial bundle 4MB. Subpackage system extends to 20MB total. Custom JS engine, not standard WebView. Native canvas API and a subset of WebGL.
- Best fit genres
- High-throughput casual genres: HTML5 hyper-casual, idle, match-3, party games. Tencent ecosystem virality is unmatched at scale.
Where studios get stuck.
Custom JS engine breaks portability from web. ICP and content review require a Mainland publishing entity or a publishing partner. Payment is WeChat Pay only, with strict revenue share. The 4MB initial bundle target forces aggressive subpackage splitting.
How Hangar handles it.
Hangar's WeChat adapter targets the 4MB bundle with automated subpackaging, generates the WeChat Mini Games engine-compatible build, and surfaces a publishing-partner relationship for ICP and content review. The hard work is platform engineering, not your gameplay code.
Common questions about WeChat.
Do I need a Chinese company to publish on WeChat Mini Games?
Yes, in practice. The publishing entity needs an ICP filing tied to a Mainland Chinese business license. Foreign studios usually publish through a co-publisher or a Mainland subsidiary. Hangar's WeChat track surfaces partner relationships for this.
What is the 4MB bundle limit?
WeChat Mini Games loads an initial bundle of at most 4MB. Additional content loads as subpackages, capped at 20MB total. This forces aggressive content splitting that most game engines do not handle automatically. Hangar splits and stages content per WeChat's subpackage rules.
Is WeChat the largest MiniApp platform?
By active gamers, yes. Around 500M players touch WeChat Mini Games monthly. Most of that audience is in Mainland China. Outside China, WeChat reach drops sharply.
