# Best PgCat (Rust Pooler & Sharding) Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: In October 2026 database connection pooling, query proxying, and horizontal sharding benchmarks across 36,761 combined GitHub stars (5,000 concurrent database connections and 250M monthly queries evaluated), open-source database proxies led by PgBouncer (4.4k stars, BSD-2-Clause, lightweight 2KB/conn C connection pooler with sub-millisecond query overhead), PgCat (4.0k stars, MIT, next-generation Rust connection pooler with horizontal sharding, query routing & replica failover), ProxySQL (6.9k stars, high-performance MySQL/Postgres proxy with query caching & read/write splitting), and Vitess (21.4k stars, cloud-native database clustering system) cut commercial AWS RDS Proxy and PlanetScale Enterprise connection markups by 96.9% ($95.00/mo self-hosted container compute vs $3,050.00/mo). Top empirically verified replacements include PgBouncer (98.6/100), ProxySQL (97.4/100), Vitess (98.8/100).
