Data Mirror vs Estuary Flow

Self-hosted simplicity vs a managed pipeline service

Estuary Flow is a fully managed SaaS that streams database changes to Elasticsearch with sub-second latency. Data Mirror is self-hosted, one-time-priced software — your data never leaves your own infrastructure.

Managed services handle scaling, uptime and upgrades for you
