The Opportunity

Problem

Solo indie hackers building matching platforms hit Supabase scalability limits in single-person setups, blocking growth without expert tweaks.

Solution

SupaShard detects high-traffic matching tables in your Supabase project and automatically partitions them across multiple schemas or external Postgres pools. It provides a dashboard to monitor shard performance and handles query routing seamlessly via a proxy layer. Solo indie hackers can scale from 10k to 1M+ matches without hitting row limits or query timeouts.
