尽管 GitHub 的用户数量和代码库规模持续增长，但部分知名开源项目已开始迁移至 Codeberg 等替代平台或采用自托管模式 [1]。这一趋势主要源于用户对 GitHub 频繁宕机、AI 功能强制整合以及公司政治立场的不满 [1]。目前市场上存在 GitLab、Bitbucket 等多种替代方案，反映了开发者对代码托管服务多样性的需求 [1]。
Ghostty 维护者 Mitchell Hashimoto 于 2026 年 4 月宣布该项目将离开 GitHub[1]。与此同时，Zig 语言项目也已于 2025 年 11 月宣布脱离该平台 [1]。IncidentHub 记录显示，在 2025 年 5 月至次年期间，GitHub 共发生 48 次重大宕机，累计停机时间达 112 小时 [1]。
对于 GitHub 强制整合 AI 功能的政策，CEO Thomas Dohmke 曾在 2025 年表示：“要么拥抱 AI，要么退出这个行业”[1]。此外，Zig 创始人 Andrew Kelley 还提及了 GitHub 与 ICE（移民执法局）签署的 20 万美元合同争议 [1]。
Despite continued growth in user numbers and repository size on the platform, several prominent open-source projects have begun migrating to alternative hosting services like Codeberg or adopting self-hosted models [1]. This shift is driven by developer dissatisfaction with frequent outages, mandatory integration of AI features, and concerns over corporate political stances [1].
Mitchell Hashimoto, maintainer of Ghostty, announced in April 2026 that the project would leave GitHub [1]. Similarly, the Zig programming language project declared its departure from the platform in November 2025 [1]. These moves reflect a broader trend where developers seek diversity in code hosting options amidst available alternatives such as GitLab and Bitbucket [1].
Reliability concerns are central to this migration. IncidentHub records indicate that between May 2025 and early 2026, GitHub experienced 48 major outages totaling 112 hours of downtime [1]. Additionally, the platform's leadership has pushed for AI adoption; in 2025, CEO Thomas Dohmke stated, "Either embrace AI or leave this industry" [1]. Political controversies have also fueled discontent. Andrew Kelley, founder of Zig, highlighted disputes regarding GitHub's $2 million contract with ICE (Immigration and Customs Enforcement) as a factor influencing the platform's reputation among developers [1].
