Migrate and continuously sync MySQL and Postgres, and import SQLite / Cloudflare D1 — 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. SQLite files (and a wrangler d1 export .sql dump), live Cloudflare D1 databases, CSV / TSV / NDJSON files, and mydumper / pscale dump directories also import into Postgres or MySQL, and SQLite is itself a migrate target — 14 engines are registered today (run sluice engines to list them). 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.
