ESLint

Slow performance on large codebases compared to newer tools like Oxlint and Biome
Complexity in configuration from scratch, particularly for TypeScript support
Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

PlanetScale

EBS High Availability requires 3-node configuration with replication overhead
EBS Non-HA single-node option lacks redundancy and automatic failover
Pricing varies by cloud provider and region, requiring queries for specific rates
ARM64 architecture only available on EBS tier, not Metal deployments
