Is Weavori a good alternative to Mockaroo?

For PostgreSQL teams, yes. Weavori introspects your live schema, resolves foreign keys automatically, samples production distributions, and exports directly into a target database — capabilities Mockaroo lacks because it is a hand-built field form with no schema awareness.

Does Mockaroo support foreign keys?

No. Mockaroo has no schema or foreign-key awareness — you define every field manually and manage relationships yourself. Weavori reads your schema and guarantees referential integrity by construction.

Can Mockaroo run in CI/CD pipelines?

Only via its REST API and file downloads. Mockaroo has no CLI. Weavori is CLI-native with API keys, plain/JSON output, and standardized exit codes, making it a first-class CI citizen.

How does Weavori pricing compare to Mockaroo?

Mockaroo bills annually ($60–$7,500/year) with per-file and per-day row caps. Weavori's Free tier is 2,000 rows/month forever, and Pro is $15/month for 1,000,000 rows with no per-file limits.

Random Data Generator and API Mocking Tool

Mockaroo is a browser-based test data generator with 100+ data types, a visual field builder, and API mocking — the easiest possible way to get sample rows without installing anything. It is not schema-aware: you define every field by hand, there is no foreign-key awareness, no CLI, and no distribution sampling. Weavori reads your live PostgreSQL schema and generates referentially intact data with production-shaped distributions, from a terminal, in CI, or via direct database export.

How they compare

A closer look at the dimensions that actually change the decision — and the honest trade-offs in each.

Workflow shape

weavori

Weavori connects to your database (or accepts pasted DDL), reads the schema, and generates. Foreign keys resolve themselves; distributions come from pg_stats. Output streams to stdout or directly into a target database via COPY.

mockaroo

Mockaroo's flow is a web form: pick fields, pick data types, download a file. There is no schema introspection — you recreate your columns by hand, and there is no foreign-key concept, so relational integrity is entirely on you.

Bottom line: For a one-off flat CSV of names and emails, Mockaroo's form is faster. For anything relational, Weavori's schema awareness removes the work and guarantees integrity by construction.

Realism

weavori

Weavori samples PostgreSQL's column statistics (pg_stats) so value frequencies match production — a status column that is 70% active stays 70% active — and enforces cross-column coherence like temporal ordering and conditional nullability.

mockaroo

Mockaroo generates from its data-type library with uniform randomness. Its own marketing notes it catches edge cases like unicode and apostrophes, but it does not shape output to your production distributions.

Bottom line: If your tests or query plans depend on data that behaves like production, Weavori's distribution sampling matters. For prototyping with plausible-looking values, Mockaroo suffices.

Automation and CI

weavori

Weavori is a CLI with API keys, plain/JSON output, standardized exit codes, and a schema cache — designed to run in CI pipelines and be driven by AI assistants via its MCP server.

mockaroo

Mockaroo offers a REST API for programmatic downloads and saved schemas, but there is no CLI and no first-class CI story. Pipelines must script HTTP calls and handle files out-of-band.

Bottom line: For automated pipelines, Weavori's CLI-native design wins. Mockaroo's API is a bolt-on, not a workflow.

Cost at scale

weavori

Weavori's Free tier is 2,000 rows/month with unlimited runs; Pro is $15/month for 1,000,000 rows. No per-file limits, no speed throttling.

mockaroo

Mockaroo caps rows per file and per day by tier ($60/year for 100K rows/file, $500/year for 10M, $7,500/year enterprise), throttles generation speed below Gold, and bills annually.

Bottom line: For continuous generation — dev databases, staging refreshes, CI runs — Weavori's flat monthly fee with no caps is cheaper and simpler. For occasional single-file downloads, Mockaroo's annual plans are competitive.
