The Challenge

Supabase, one of the most popular open-source backend platforms, is blocked or severely throttled in India and several other regions. Developers building production applications on Supabase suddenly find their apps broken for a large portion of their user base. The existing workarounds (VPNs, self-hosted instances) are either unreliable, expensive, or too complex for indie developers to maintain.

Our Approach

We built a Cloudflare Worker that acts as a transparent proxy between the developer's application and Supabase's API endpoints. The developer changes one URL in their Supabase client configuration and everything works. No SDK changes, no server-side modifications, no complex networking setup. The proxy handles authentication passthrough, request routing, and edge caching for static assets. Deployed globally on Cloudflare's edge network for minimal latency.

What We Built

Cloudflare Worker proxy that transparently routes all Supabase API requests
Authentication passthrough that preserves Supabase auth tokens and RLS policies
Edge caching layer for static assets and frequently accessed data
Landing page with one-click setup instructions and real-time status monitoring
Custom domain routing so developers get a clean proxy URL

Delivery Timeline

Key Takeaways

The simplest possible developer experience wins adoption. One URL change beats any amount of documentation or configuration guides.

Cloudflare Workers gave us global edge deployment with zero cold starts. The proxy adds less than 10ms of latency in most regions.

Building a free tool that solves a real pain point for developers creates organic distribution. The tool spread through dev communities without any marketing spend.
