A Snaplet alternative that copies production to your Mac

Snaplet closed in August 2024. Its seed and fake data tools live on as open source, but Snapshot, the part that copied a masked subset of production, is archived. dbplex is a Mac app that pulls a copy of your production database to localhost, masks personal columns on the way in, and lets you save, branch and refresh it.

Snaplet: Closed in August 2024
Snapshot: Archived on GitHub
Seed: Fake data, open source
dbplex: A Mac app, 7 days free

Which one fits

Snaplet did two jobs: fake data generated from your schema, and a masked copy of real data. The open source Seed still does the first. dbplex does the second.

Pick Snaplet if

You want fake rows generated from your schema, with no access to production at all.
You want seed scripts kept in your repository that run the same way in CI.
Your team works on Linux or Windows.

Pick dbplex if

You want your real rows, not invented ones, with personal columns masked.
Your database is Supabase, MySQL, MongoDB, Firestore or another of 12 engines, not only Postgres.
You want a tool with current releases rather than an archived command.
You want your AI agent on a copy through MCP, never on production.

Snaplet and dbplex, side by side

Snaplet's parts after the shutdown, next to dbplex.

	Snaplet	dbplex
Status	The company closed in August 2024. Snapshot is archived; Seed and Copycat are open source under MIT.	A Mac app with current releases and support.
Data you get	Snapshot: a transformed subset of Postgres. Seed: fake rows from your schema.	Your real rows, read from production. On Turso, every row or a sample per table.
Personal data	Transformed by Snapshot, or never real with Seed.	Masked as the copy is pulled on Postgres, Supabase, MySQL, MariaDB, Turso, SQL Server and Oracle. You confirm each column.
Databases	Snapshot: Postgres. Seed: Postgres, MySQL and SQLite.	12, from PostgreSQL and Supabase to MongoDB, Firestore, Redis, DynamoDB, SQL Server and Oracle.
Where it runs	Commands you run and wire up yourself, locally or in CI.	One Mac app. Each copy runs on localhost with its own URL.
Going back	Restore the snapshot again.	Save a state and restore it, or branch the copy. Not yet on Supabase, where a backup opens as a new copy.
AI agents	Not covered.	A built-in MCP server whose tools act on local copies only. The agent never sees production credentials.

Moving from Snaplet

Keep Seed if your tests rely on generated rows. It works against a dbplex copy like any other database.
Install dbplex and paste your production connection string. Production is only read.
Confirm which personal columns to mask, then pull.
Point your app, your tests and your agent at the localhost URL in the Connect tab.

Questions about Snaplet and dbplex

Is Snaplet still available?

No. The company closed in August 2024 and its tools went open source on Supabase's community account on GitHub. Snapshot is archived there, and Seed has had no npm release since August 2024.

Does dbplex make fake data like Snaplet Seed?

No. dbplex copies your real data and masks personal columns. If you want generated rows, Seed still works against a dbplex copy.

Can dbplex copy only part of a database, like Snapshot did?

On Turso, yes: a sample of 1 to 1,000,000 rows per table, with every row they point to. On the other engines it copies everything.

Does dbplex run in CI?

No. dbplex is a Mac app for your own machine. For CI, a seed script or a dump step is still the right tool.
