A Neosync alternative, now that Neosync is archived

Grow Therapy acquired Neosync in September 2025, and the open source repository is no longer maintained. If you used it to get masked production data into development, dbplex does that for each developer: it copies production to your Mac, masks personal columns on the way in, and gives the copy a localhost URL.

Which one fits

Neosync was a pipeline for teams: it anonymised and synced data into staging and CI. dbplex is a desktop app that gives each developer a masked copy on their own Mac.

Pick Neosync if

You need one shared, server-run pipeline that fills staging and CI for the whole team.
You need synthetic data generated from scratch.
You need subsets defined by any SQL query.

Pick dbplex if

You want a maintained tool rather than an archived one.
You want masked data on your own Mac without running Docker Compose or Kubernetes.
Your database is one of 12 engines, including Supabase, Firestore and Redis.
Your AI agent should work on that copy through MCP.

	Neosync	dbplex
Status	Acquired by Grow Therapy in September 2025. The repository is archived and no longer maintained.	A Mac app with current releases and support.
Setup	Docker Compose or Kubernetes, then connections and jobs in its web interface.	Install the app and paste a connection string.
Where data lands	The destination database each job syncs to.	A local server on your Mac, with a localhost URL.
Personal data	Transformers, including your own in JavaScript.	Masked as the copy is pulled on Postgres, Supabase, MySQL, MariaDB, Turso, SQL Server and Oracle. You confirm each column.
Subsets and synthetic data	Both: subsets by SQL query, and generated data.	Neither, except a sample per table on Turso.
Databases	Postgres, MySQL, SQL Server, MongoDB, DynamoDB and S3.	12, including Supabase, Firestore, Redis, Turso and Oracle.
Going back	Run the job again.	Save a state and restore it, or branch the copy. Not yet on Supabase, where a backup opens as a new copy.
