Hashicorp co‑founder Mitchell Hashimoto has declared GitHub no longer viable for serious work, citing daily outages that cripple his terminal‑emulator project Ghostty. After 18 years on the platform, he plans to shift the codebase to a different host while keeping a read‑only mirror on GitHub. The move follows a series of reliability blips, including an April 28 Elasticsearch failure that stalled pull‑request builds.

Hashimoto’s frustration grew after a month of outages, each marked with an “X” in his personal journal. He cited a GitHub Actions outage that left him unable to review pull requests for two hours, and a broader pattern of instability that erodes developer productivity. The frustration culminated in a public post that urged GitHub to deliver tangible fixes instead of promises.

Despite his departure, Hashimoto will keep Ghostty’s read‑only copy on GitHub and may return if the platform resolves its reliability issues. Meanwhile, Microsoft’s ownership of GitHub has sparked debate over the service’s future direction, especially as the company pushes AI features and telemetry. For now, developers watching the fallout must decide whether to stay or move on.
