Ghostty, the open‑source toolkit behind the popular Ghost blog engine, announced it will leave GitHub after nearly two decades of dependency. The move follows repeated outages that halted pull‑request reviews and CI workflows, forcing the team to rethink its infrastructure.

Founder Caleb Williams, who began his career on GitHub, cited daily disruptions—most recently a 27‑April 2026 Actions outage—as a tipping point. Over 18 years, GitHub had been the backbone for his projects, but mounting reliability issues made continued reliance untenable.

The team plans a gradual migration to alternative hosting providers, retaining a read‑only mirror on GitHub. Personal projects will stay on the platform for now, but Ghostty’s core community will shift elsewhere once dependencies are removed. The decision, made after months of planning, signals a broader challenge for projects tied tightly to a single platform’s stability.
