Explorer
Manage connection groups, browse tables, run guarded SQL, import CSV, detect schema drift, and inspect live data.
v1.0 · Desktop app for macOS & Windows
Your database workspace — explore, seed & analyze
Synrows is more than test data. Connect to live databases, browse schemas, run guarded SQL, define generation rules with AI, seed realistic rows, and build monitor views and printable reports — locally or with optional cloud AI.
Three workspace modes
One app for schema exploration, data generation, and analytics — not just seeding.
Seed
Create seed tasks, define per-table rules with AI, preview rows, and apply Faker or local LLM output to your database.
Analyze
Design monitor views with SQL guardrails, compose printable reports, and use AI to draft metrics and narrative blocks.
How it works
From empty project to explored, seeded, and reported database in minutes.
- Create a project and connect Postgres, MySQL, SQLite, MongoDB, or more
- Import or introspect schema — SQL paste, files, or live connection
- Define seed rules with cloud AI, BYOK, or a local LLM — preview before apply
- Generate data, browse results in Explorer, and build reports in Analyze

Common questions
Is Synrows only for generating test data?
No. Synrows is a full database workspace: explore schemas and run SQL in Explorer, generate and apply data in Seed, and build monitor views and reports in Analyze. Test data is one powerful use case, not the whole product.
Do I need Node.js installed?
No. Packaged builds include a bundled Node sidecar for the local server.
Which databases are supported?
SQLite, Postgres, MySQL, MongoDB, Supabase, Cloudflare D1, and an in-app demo adapter.
Can I use Synrows completely offline?
Yes. Explorer, Seed with Faker, and local LLM generation work offline. Cloud AI, device registration, and BYOK require network access.
How does local LLM generation work?
Download a model from the in-app catalog (powered by Hugging Face Transformers). Generation runs on your machine — no data leaves your device unless you opt into cloud AI.
Does cloud AI require an account?
Synrows Cloud registers your desktop device automatically on first use. Free tier includes a daily quota; Cloud Pro increases limits. You can also bring your own API keys or revoke cloud access anytime.
What is included in Cloud Pro?
Cloud Pro unlocks a higher daily quota for Synrows Cloud AI — schema analysis, rule refinement, SQL generation, and report design. The desktop app itself remains free.
Is my database data sent to the cloud?
Cloud requests send schema summaries and prompts — not your full database contents. Local generation and browsing never leave your machine. See our Privacy Policy for details.
How do updates work?
The desktop app checks updates.synrows.app for signed releases and can auto-update from
the in-app updater. Download links on this page always point to the latest stable build.
