Cloudflare Workers Free pricing & rate limits

Cloudflare D1 represents a departure from traditional instance-based database hosting. Instead of selecting specific RAM or CPU tiers typical of competitors like AWS RDS or DigitalOcean, D1 operates on an abstracted serverless model. The base workload baseline starts at $0.00/mo, which serves as a functional free tier for development. While Cloudflare does not strictly limit RAM for your queries, the platform allocates 1 vCPU core for execution. You start with 5 GB of included storage, which is sufficient for light to moderate application state but requires careful monitoring for larger datasets.

• Exceeding the 5 GB storage limit triggers an overage fee of $0.015/GB per month.
• The serverless design means you are not provisioning traditional NVMe SSDs or AMD EPYC instances, as the underlying hardware layer is fully abstracted from your configuration.
• Database connection management is handled through a global edge network, removing the need for manual connection pooling or proxy configuration found in legacy Postgres architectures.
• Pricing for production-grade production workloads is entirely custom, requiring direct engagement with their sales team rather than selecting a predefined monthly billing tier.

This model suits developers building on the Cloudflare Workers ecosystem who need to avoid the maintenance of traditional database clusters. Because you do not manage the underlying replication or high-availability failover, the platform is best for applications that prioritize low-latency reads across global regions over complex relational data structures. Projects that require predictable, fixed-cost monthly billing for massive, static datasets will find the custom sales-led pricing structure less transparent than standard flat-rate VPS providers. If your application architecture relies on consistent, long-running background processes that exceed standard serverless execution limits, you will eventually reach the ceiling of what this specific database abstraction can support.
