About this hackathon

A free, month-long online hackathon run by Reskilll for Nexconn: build a real-time, chat-driven app on the Nexconn Chat SDK (Chat UI counts; the Call SDK for voice/video is optional) for Web, iOS, Android or Flutter. Tracks cover social, gaming and live streams, workplace, marketplace and support, social good, or anything open. Teams of 1–4; existing projects are fine if you add a real Nexconn integration during the challenge. Submit an app link, public repo, demo video and write-up by Nov 22, 2026, 23:59 AoE. $5,000 cash across five winners (1st $2,000) plus a two-year free chat plan. Not open to residents of Mainland China.

一句话简介：Reskilll 替即时通讯 SDK 厂商 Nexconn 办的一个月线上黑客松，⁠‍‌‌‍‍‌‌‍‌‌‍‍‍‍‍‌‍‍‌‌‍‌‌‌⁠用 Nexconn Chat SDK 做一个实时聊天驱动的应用。

看点：必须用 Chat SDK（Chat UI 也算），语音视频 Call SDK 可选；Web、iOS、Android、Flutter 都支持；方向举例有社群、游戏与直播、办公协作、电商客服、公益无障碍，也可开放命题；1—4 人一队，可单人；老项目可以交，但要在赛期内加上真实的 Nexconn 集成并说明哪些是新做的；评分一半看能不能完整跑通；交可运行链接、公开仓库、演示视频、说明 PDF 和 App Key；中国大陆居民不能参加

奖金：现金共 5,000 美元，第一名 2,000，第二 1,250，第三 750，第四、五名各 500；获奖队另得 2 年免费聊天套餐

截止日期：11 月 22 日 23:59 AoE（北京时间 11 月 23 日 19:59）

活动日期：2026年10月23日—11月22日（全球线上），11月23—27日评审，12月1日公布结果
