Codespaces spending-limit alert thresholds and notification recipients

Direct answer

Spending-limit alert percentages are fixed by GitHub and cannot be customized by organization admins. Alerts go by email to organization owners and billing managers only. Individual users, Slack channels, and webhooks are not supported recipients. Control availability varies by GitHub plan.

Confirmed facts

• GitHub sets the usage-alert percentages. The organization billing UI lists them, but admins cannot add custom thresholds.
• Recipients are limited to organization owners and billing managers. There is no documented opt-in for individual members, Slack, or webhook delivery.
• When the organization limit is reached, GitHub blocks new codespace creation until the limit is raised or the next billing cycle begins. Already running codespaces are not stopped.
• Alert delivery can lag behind actual usage, so treat emails as awareness signals rather than hard cost cutoffs.

Steps to verify in your organization

1. Open organization settings, then go to Billing and plans > Codespaces spending limit.
2. Review the listed alert percentages and confirm the recipient email addresses.
3. Confirm your organization's GitHub plan (Free, Team, or Enterprise Cloud), because spending-limit controls vary by plan.
4. Check recent billing emails to verify delivery and recipient addresses.

Missing detail

Which GitHub plan is your organization on? GitHub Free may not expose the same paid Codespaces spending controls, so the plan determines whether these thresholds and recipients exist at all.
