Reads your ORM config
Drizzle and Prisma first. Also TypeORM, Knex, ActiveRecord, Django, and Sequelize. One command in your terminal, zero copy-pasting connection strings.

No Electron, no subscription. Per-user license for all your Macs. Direct connection, your data never leaves your machine.
Your ORM models and the live database drift apart. QueryDeck keeps that comparison visible in a dedicated read-only view: Drizzle Kit can compute code-vs-DB changes through `push`, while Prisma detects development drift through `migrate dev`. Drift Mode also covers TypeORM, ActiveRecord, and Django. Knex and Sequelize get auto-connect but no Drift Mode.
Your database becomes a tool for Claude Code, Cursor, and any MCP client. Schema, queries, and table introspection — exposed as native tools.
Reproduce a production bug locally without cloning production.
Pick the row that reproduces the issue and choose Bring to Local…. QueryDeck follows the required relationships, reviews sensitive fields with you, sanitizes the selected dataset, and provisions a local PostgreSQL snapshot you can debug safely.
How Local Snapshot works →Stop copy-pasting connection strings. QueryDeck reads your Drizzle or Prisma config first (deepest support), plus TypeORM, Knex, ActiveRecord, Django, and Sequelize, and connects instantly.

“Schema drift between ORM and prod is one of those quiet incidents that only bites at 3am. A native client that catches it in your terminal before you ship is the kind of tool I've been waiting for.”
WHY TIMESTAMP / TIMESTAMPTZ MATTERS · POSTGRESQL WIKI · DON'T DO THIS
Your database client sees tables. QueryDeck sees your project.
Open a Prisma or Drizzle project, let QueryDeck detect the connection, inspect the schema, and catch drift before it ships.

Which ORMs does the CLI auto-detect?
Auto-connect works for 7 ORMs: Drizzle, Prisma, TypeORM, Knex, Django ORM, ActiveRecord, and Sequelize. Run `querydeck` in your project directory and it reads the config automatically.
Which ORMs does Drift Mode actually parse?
Drift Mode has 5 schema parsers today: Drizzle, Prisma, TypeORM, Django ORM, and ActiveRecord. Drizzle and Prisma get the deepest support because that is where the drift gap is widest. Knex and Sequelize auto-connect today but don't have Drift Mode parsers.
What does Drift Mode actually catch?
Missing or extra columns, column type drift (with smart canonicalization across ORM and database dialects), nullability mismatches, default value drift, missing or extra simple indexes, missing or extra foreign keys, and column-level enum type drift. It also skips known false-positive sources: client-side defaults (UUID, CUID, NANOID, ULID), type aliases (timestamptz vs timestamp with time zone), and PK-implied unique indexes.
What does Drift Mode NOT catch (yet)?
Functional or expression indexes are compared as raw column names. Check constraints, triggers, rules, and generated columns are not modeled. Index onDelete and onUpdate behavior changes are ignored. Partial index WHERE clauses are intentionally skipped (this is what avoids the false positives Prisma's migrate diff produces). Views are filtered out. Custom types like PostGIS geometry depend on each ORM parser.
What are query notebooks?
Interactive documents mixing SQL cells, Markdown notes, and inline results. Think Jupyter, but for databases. Export to PDF or HTML to share with your team.
What databases does QueryDeck support?
PostgreSQL, MySQL, SQLite, and MongoDB. Four databases, one native macOS app.
Does QueryDeck require a subscription?
No. Lifetime is $79 for the first 10 customers, then $149. Per-user license, use on all your Macs.
Is my data sent to the cloud?
No. Direct connection from your Mac to your database. The optional AI assistant sends only your schema, never your rows. Use Ollama or on-device AI for fully offline mode.
What is Local Snapshot / Bring to Local?
On PostgreSQL, select a real row and choose Bring to Local. QueryDeck follows the related foreign-key context, lets you review privacy transforms, then creates a sanitized local PostgreSQL snapshot for reproducing the bug without turning production into your dev environment.
Is QueryDeck built with Electron?
No. Built with Swift and AppKit. No Java, no Electron, no embedded browser. Sub-second launch, under 200 MB RAM.
