A command-line tool that reads a database schema and generates a full, realistic fake dataset plus a ready-to-run dbt project — no production data or manual scaffolding needed.
Best alternatives to datagen in 2026
Generating realistic test data at scale is usually either slow (data generated interpretively, row by row, in a scripting language) or crude (random values with no logical relationships between fields or tables). datagen takes a different approach: you describe your data model once in a small, declarative language, and it compiles that description into native code before running it — so generating millions of coherent rows is fast rather than a bottleneck. datagen's domain-specific language uses Go-like syntax to define entity shapes, cross-references between models, and tag-based filtering rules, which the tool then transpiles into native Go code for the actual generation step. It outputs to CSV, JSON, XML, or stdout, and can write directly into a MySQL database. It ships built-in functions for common data-generation patterns so you're not writing everything from scratch. It's MIT-licensed, written in Go (1.24+), and at 60 GitHub stars is a small but functioning project rather than a widely-adopted standard.
