What GitHub's Copilot usage metrics cover
For Copilot on its own, start with GitHub. Its Copilot usage metrics dashboard shows 28-day trends for enterprises and organizations, and its APIs report down to the repository and user level: daily and weekly active users, code completion acceptance rate, and an impact dashboard that connects adoption to pull request output.
Zest answers the cross-tool question: which coding agent, model and skills each engineer reaches for, and which sessions turn into merged pull requests.
The Zest extension for VS Code reads Copilot Chat sessions: the conversation, the models used, and the skills and tools they called.
Inline completions are not captured. GitHub's own metrics stay the source for acceptance rates.
Claude Code, Codex, Cursor, Grok Build and Hermes report into the same dashboard, so usage is comparable across tools.
Copilot ROI: usage next to what ships
Judging Copilot's ROI starts with two things side by side: how each engineer uses it, and what they merged. The Zest GitHub App puts each engineer's Copilot Chat sessions next to their merged pull requests, and Zest reports PR cycle time too; which delivery numbers to trust is on developer productivity metrics.

Starter is free (3 seats, no credit card). Pro is $49 a month with 5 seats and Max is $149 a month with 10 seats — priced per workspace, not per engineer, with extra seats at $19 a month.
GitHub provides a Copilot usage metrics dashboard and REST APIs for organization and enterprise admins. Zest adds Copilot Chat sessions per engineer next to Claude Code, Cursor and Codex, and what each engineer merged.
Does Zest capture Copilot inline completions?+
No. Zest reads Copilot Chat sessions in VS Code. For completion acceptance rates, use GitHub's Copilot usage metrics.
Can I see GitHub Copilot usage per engineer?+
GitHub's Copilot usage metrics APIs report down to the user level. Zest adds each engineer's Copilot Chat sessions, with their models, skills and tools.
