Mitchell Hashimoto says GitHub ‘no longer for serious work'

HashiCorp co-founder Mitchell Hashimoto has publicly announced he is leaving GitHub after nearly 18 years, citing near-daily outages that have blocked his ability to work on Ghostty, his open-source terminal emulator. He kept a month-long journal tracking GitHub outages and found almost every day was impacted. Hashimoto is now evaluating both commercial and FOSS alternatives to host Ghostty, while leaving a read-only mirror on GitHub. He links the reliability decline to Microsoft's AI-driven changes and says he'll return only if GitHub delivers real improvements, not promises.
