The Five Supabase Regions: Performance by Geography

- **Frankfurt**: Serving European markets with low-latency connections to Germany, France, and the Benelux countries. Ideal for startups and enterprises targeting EU compliance with GDPR. - **Seattle**: The default North American region, optimized for applications serving users across the U.S.

and Canada. Features DMZ-class networking and redundant cloud interconnects for high availability. - **Mumbai**: A strategic hub for South Asia, supporting India’s growing digital economy with direct access from Mumbai, Bangalore, and Delhi.

- **Sydney**: Designed for Oceania, delivering strong performance for Australian and New Zealand users while connecting to Pacific networks. - **Pune**: Emerging as a high-performance option for Indian and Southeast Asian markets, leveraging local cloud infrastructure and low-latency interzone links. “Choosing the right region is like placing a phone line—you’re not just connecting users, you’re defining trust,” says Leila Chen, Lead Cloud Architect at a fast-growing FinTech startup using Supabase in SE Asia.

“Latency isn’t just a technical nuance; it’s a direct factor in user retention and transaction success.”

Each region runs on Supabase’s serverless PostgreSQL-backed infrastructure, ensuring consistent APIs and service-level agreements—even as geographic boundaries change deployment logic. Developers benefit from identical feature parity across regions, but regional differences in network topology, data residency laws, and latency profiles create distinct advantages.

Data Sovereignty and Regulatory Compliance: The Non-Negotiable Edge

Developers must evaluate: - **Local data residency requirements**: For example, EU-based applications must ensure personal data remains within the European Economic Area. Supabase’s Frankfurt region simplifies GDPR compliance by guaranteeing in-EEA data storage. - **Cross-border transfer restrictions**: Regions integrate with Supabase’s data transfer tools, enabling compliant movement between zones when supported by applicable agreements.

- **Audit and certification alignment**: Certain regions host compliance frameworks audit-ready for industry-specific certifications, such as ISO 27001 or SOC 2, critical for regulated sectors like healthcare and finance. “Regulatory pressure is rising, but Supabase’s regional architecture actively mitigates risk,” notes Raj Patel, Chief Compliance Officer at a global SaaS platform. “By deploying in Mumbai or Pune, we ensure Indian user data never exits the subcontinent—without sacrificing performance.”

This regional granularity empowers developers: ensure compliance without sacrificing speed, a balance increasingly vital for global scale and user trust.

Performance Priorities: Minimizing Latency, Maximizing Engagement

Supabase’s regional design minimizes data travel distance, reducing round-trip times to milliseconds—critical for real-time apps like chat platforms, gaming backends, or e-commerce checkouts. Real-world impact: A live chat application deployed in Frankfurt rather than Seattle or Mumbai reduces user response delays by up to 40%, according to internal benchmarks. Similarly, a news platform in Sydney serves Australian users faster than one relying solely on U.S.

regions. The Latency Formula is simple: proximity = speed. For global audiences, distributing deployment regions prevents bottlenecks and ensures interactive, seamless experiences across time zones.
