v1.0 · Free desktop app for macOS & Windows

Your database workspace — design, manage, test, monitor & report

Synrows is a local-first database workspace. Design ER diagrams, manage connection groups, seed realistic datasets for dev and QA, monitor with guarded SQL views, and publish printable reports — with Faker, local LLM, BYOK, or optional Synrows Cloud AI.

Features

Three workspace modes

One app for schema exploration, data generation, and analytics — not just seeding.

Explorer

Connection groups, health badges, schema drift detection, ER diagrams, guarded SQL browse, CSV import, and live data inspection.

Seed

Seed tasks with versioned rules, Faker heuristics, local LLM or cloud AI column rules, preview-before-apply, and cache mode.

Analyze

Monitor views (table, metric, chart, list), printable report layouts, SQL guardrails, and AI-assisted metrics and narrative blocks.

15+ database adapters

SQLite, Postgres, MySQL, MariaDB, CockroachDB, Turso, MongoDB, Supabase, D1, SQL Server, Oracle, Db2, and read-only warehouses.

Connection lifecycle

Lazy connect with pooling, per-connection query scheduling, health pings, and read-only enforcement for warehouse adapters.

AI your way

Synrows Cloud AI, bring-your-own-key (OpenAI/Anthropic), or fully offline local LLM via Hugging Face — your data stays local by default.

Workflow

How it works

From empty project to explored, seeded, and reported database in minutes.

  1. Create a project, organize connections into groups, and test health from the sidebar
  2. Import or introspect schema — SQL paste, files, live connection, or ER diagram design
  3. Define seed rules with Faker, cloud AI, BYOK, or a local LLM — preview before apply
  4. Generate data, browse results in Explorer, monitor with SQL views, and export reports in Analyze

FAQ

Common questions

Is Synrows only for generating test data?

No. Synrows is a full database workspace: design schemas and manage connections in Explore, seed datasets for dev and QA in Seed, and monitor plus report in Analyze. Data generation is one capability—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, MariaDB, CockroachDB, Turso, MongoDB, Supabase, Cloudflare D1, SQL Server, Oracle, Db2, and read-only warehouse adapters (Redshift, Synapse, Snowflake, BigQuery).

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.

What is your refund policy?

Cloud Pro includes a 14-day money-back guarantee on your first subscription payment — no questions asked. The desktop app is free and not subject to refunds. See our Refund Policy for cancellation and renewal terms.

How do I cancel Cloud Pro?

Cancel anytime from the Paddle customer portal linked in your receipt email, or contact [email protected]. Cancellation stops future charges at the end of the current billing period.

Do warehouse databases support writes?

Redshift, Snowflake, BigQuery, and Azure Synapse adapters are read-only in Synrows — ideal for monitoring and reporting. Writable adapters can also be marked read-only per connection.

What about Oracle and Db2?

Oracle and IBM Db2 are supported but require native client libraries (Instant Client / CLIDriver) installed on your machine. They are not bundled with the Synrows installer.

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.
