present open source development in China from various dimensions. This year we set off again, combining data analysis tools and survey reports in various forms to draw a map of the Chinese open source scenarios ：以在线问卷方式搜集样本和数据，交叉对比法分析数据 Survey method: Online questionnaire to collect samples and data, cross-comparison method to analyze data 推广方法 ：线上社交媒体、博客、开源社、开源中国网站 Promotion method: Online social media, blogs 年的统计数据，并对比往年数据和其它一些公开发布的统计报告，我们有如下 一些重要发现： By analyzing the statistics for 2021 and comparing previous years' data with some other publicly released statistical reports, we have some significant findings as follows:

1 开源商业模式验证 开源软件公司迎来上市潮，多家公司估值已突破 100 亿美元。1999 年，Red Hat 在纳斯 达克上市为开源软件公司进行商业化点燃信心。据不完全统计，自此已有近 20 家开源软 件公司纷纷走上了上市的道路。我们看到，开源软件公司在上市之初的估值，也从最开始 Red Hat 的 36 亿美元，提升到 GitLab 的 110 亿美元。同时，公司上市后市值也在不断上升。 些依赖关键任务系统项目的客户才愿意为支持付费。 然而，那些严重依赖项目的人自然会随着时间的推 移投入自己的工程努力来了解项目，从而减少对外部支持的需求。选择 Support 支持服务商业路径的主 要公司案例是 Red Hat。 Hosting 托管——供应商将其开源软件作为服务托管在云上，通过收取每月 / 每年的托管和服务费获利。 托管意味着提供一个完全托管的项目版本，当用户想要在生产中部署时，可以使用该软件启动远程服务器， ElasticSearch $162 2018/5 56.7k 20.7k 1668 Mozilla Corporation Firefox $22 10.5k 2.4k 209 Treasure Data Fluentd $54 2016/11 10.6k 1.2k 220 GitLab Git $415 2020/11 40k 22k 408 GitHub Git $350 2015/12 39

datapoints turned into this beast. As soon as we updated one chart, we often had to update another – a data game of whack-a-mole… a pattern that shows no sign of stopping…and will grow more complex as competition related to the artificial intelligence technology evolution is indeed unprecedented, as supported by the data. This document is filled with user, usage and revenue charts that go up-and-to-the-right… often supported Threats = Rising Competition + Open-Source Momentum + China’s Rise • AI & Physical World Ramps = Fast + Data-Driven • Global Internet User Ramps Powered by AI from Get-Go = Growth We Have Not Seen Likes of
