Cross-referenced test data, not garbage rows.
Design your relational schema visually, wire up foreign keys and cardinality, and generate referentially-correct data at scale — every foreign key actually points at a row that exists.
Everything between an empty schema and a seeded database.
Relatrix isn't a random-row generator with a UI bolted on. Relationships, cardinality, and insert order are first-class — the data you get out is as structurally sound as the schema you drew.
Visual schema designer
Model tables and columns on a canvas — set types, primary keys, and constraints without writing DDL by hand.
Relationships that hold
Draw one-to-one, one-to-many, and many-to-many relationships. Cardinality is enforced when data is generated, not just drawn.
Faker-powered generation
Column-aware data synthesis picks realistic providers per type and locale, then inserts in dependency order so every foreign key resolves.
Export SQL, CSV, or JSON
Download a ready-to-run SQL dump, flat CSVs per table, or structured JSON — generated in topological insert order.
Direct seed to a live DB
Point Relatrix at a real PostgreSQL or MySQL connection and seed it directly, with SSRF-safe connection validation.
Migration DDL, generated
Turn a schema design into ordered ALTER/CREATE statements for Postgres or MySQL, respecting foreign-key dependency order.
Three steps, no throwaway scripts.
No more one-off seed scripts that drift from the schema. Design once, regenerate whenever the schema changes.
Design the schema
Add tables, columns, and data types on the canvas. Mark primary keys and connect foreign keys between tables.
Set row counts & rules
Choose how many rows per table, a locale, and a seed. Relatrix validates the schema — missing PKs, orphan relationships, circular dependencies — before you generate.
Generate & export
Watch generation run table-by-table in dependency order over a live connection, then export as SQL, CSV, JSON, or seed a database directly.
Built to be trusted with real data.
Relatrix is a normal application under the hood, not a black box — a NestJS API backed by Postgres and Redis, with a job queue for generation and a WebSocket gateway for progress. Security isn't bolted on after the fact.
Encrypted at rest
Saved connection credentials are encrypted with AES-256-GCM — never stored or logged in plaintext.
SSRF-guarded connections
Every connection to a user-supplied host is resolved and checked against loopback, private, and metadata-endpoint ranges before Relatrix ever dials out.
Real-time by default
Generation progress streams over WebSockets, table by table, with row counts as they land.
Simple, transparent pricing.
