Microsoft-owned developer platform GitHub has just experienced its “best month ever.” Chief Technology Officer Vladimir Fedorov revealed at an internal meeting on Wednesday that customer usage surged significantly in June, primarily due to adjustments in the billing model for AI coding tool Copilot. Effective June 1, Microsoft changed Copilot’s pricing structure from a fixed per-user rate to pay-as-you-go based on actual usage—aligning it with competitors such as Cursor and Codex. Fedorov stated that this change directly drove explosive growth in usage but declined to disclose specific figures, citing the approaching end of the company’s fiscal year. Regarding whether this surge would lead to higher prices, Fedorov personally believed there was no need for significant price hikes, though he did not reveal Microsoft’s final pricing strategy. Acquired by Microsoft in 2018, GitHub is the world’s most widely used code hosting and collaboration platform among developers. In the field of AI programming assistants, Copilot initially gained first-mover advantage leveraging its platform strengths. However, competing tools like Cursor, OpenAI’s Codex, and Anthropic’s Claude Code are now rapidly eroding market share. Recordings from an internal meeting late last year showed Microsoft executives stating bluntly that GitHub needed a “complete overhaul” to compete with these tools. The surging demand also brought infrastructure pressure. Since 2026, GitHub has suffered dozens of major outages. According to Business Insider, Microsoft had even sought help from its largest cloud competitor Amazon to resolve capacity bottlenecks. Microsoft declined to comment on the matter.
