Cloudflare launches Spend Management in Beta to pause activity when spending limits are reached

• Cloudflare introduces Spend Management in Beta for pay-as-you-go customers, allowing them to set spending thresholds and automatically pause activity when limits are reached to prevent unexpected bills.
• The system initially supports Workers and Durable Objects, with near real-time cost visibility in the dashboard updated within 10 minutes.
• Enforcement is asynchronous, using a Rating Engine to calculate accumulated spend and propagate caps to the global network via Quicksilver, ensuring requests do not wait on the rating process.
• Future plans include expanding to more products, reducing latency to under one minute, and enabling application-based and AI agent budgets to control costs across multiple primitives.

How It Works

• A two-stage metering pipeline aggregates raw usage events into one-minute and five-minute windows to reduce data volume before processing.
• The Usage Engine partitions processing by account to maintain consistent pricing state and accumulated usage without cross-partition coordination.
• The Rating Engine combines usage records, subscription information, and pricing rules to calculate monetary value and evaluate policy thresholds.

Availability and Limits

• Available today for Workers and Durable Objects via dashboard, cf CLI, or REST API.
• Only customer-code invocations that incur costs are paused; static assets continue to be served.
• Service resumes when the limit is raised, the policy is disabled, or the next billing cycle begins.
