Describe, then download

One tool takes a plain-English description and returns a downloadable multi-table dataset.

Real relational data

Multi-table schemas with foreign-key integrity, cardinality ratios, and exports for Postgres, MySQL, SQL Server, SQLite, and more.

Free while you try it

Request free credits for API-key / MCP usage through August 31, 2026. The web UI stays free without credits.

Get started in four steps

  1. 1

    Create a free account

    Sign in at the web app. Generating data in the browser stays free. No credits required for the session path.

    Launch App →
  2. 2

    Mint an API key (10 free credits)

    In Settings → API keys, create a key (sfk_live_…). Your first key automatically receives 10 free product credits so agents can forge and generate immediately. Copy the secret once.

    Open Settings →
  3. 3

    Need more credits? (open beta)

    API-key and MCP jobs use product credits (1 per forge / generate / ML job). Through the end of August 2026 you can email us from your account address for an extra grant after the starter pack.

FAQ

What is the MCP open beta?

You can call SynthForge from an MCP-compatible agent at mcp.synthforge.io. Describe the data you need, get multi-table synthetic data with foreign keys intact, and download the result without learning every REST endpoint.

Do I get credits automatically?

Yes. Creating your first API key grants 10 free product credits. That is enough for several forge + generate loops. Through the end of August 2026 you can also email support for an extra grant.

Is the web app free?

Yes. Browser sessions do not consume product credits. Credits apply only to automation paths: personal API keys, CLI/SDK, and hosted MCP.

How do I request more credits?

Email support@synthforge.io from the same address you use on app.synthforge.io, or use the button on this page. Include that account email so we can grant the balance correctly.

What can my agent do?

The primary tool is description_to_dataset: describe the data you need, get a schema, generate rows, and receive a download URL (and often an embedded ZIP for hosts that support attachments). You can also forge-only, generate from an existing schema, list assets, and poll job status.
