Migrate and continuously sync MySQL and Postgres — correctness-first, loud failure by default.

sluice is an open-source tool for moving and keeping databases in sync between MySQL and Postgres, in all four directions. It is built around three surfaces you can use independently or end to end:

• Migrate — a one-shot schema + data copy, with deferred indexes/constraints for fast bulk load and per-table resume.
• Sync — change-data-capture streaming with a snapshot → CDC handoff and resumable checkpoints.
• Operate — run as a long-lived service behind /readyz and /metrics, or as one-shot jobs.

Start here

• Getting started — install, connect, and run your first migration and sync.
• Command reference — every command, its key flags, and worked examples.
• Configuration — connection strings, environment variables, the YAML config file, and global flags.
