SpiceGrinder lets your teams describe the shape of their real data, then generate synthetic datasets at any scale and complexity — without ever touching PII, PHI, or a compliance review queue.

SpiceGrinder is being built for teams whose test, demo, and training work keeps stalling on access to real records. You describe entities, relationships, and distributions — the grinder produces data that can behave like production while carrying none of production data’s risk.
You know the structure of your own data. SpiceGrinder gives you the tools to describe it in a model. Then the model produces data for you that is as realistic as you chose to model.

};Generate a hundred rows for a unit test or fifty million for a load run, with complete determinism and at blazing speeds: up to hundreds of millions of rows per hour or more (exact throughput will depend on hardware used and model complexity).

Nothing is copied from production, so datasets can move freely between environments, vendors, and demos without a privacy review blocking the work. All of your data always lives inside your boundary; what you choose to do with it is entirely up to you.

SpiceGrinder is a powerful, flexible deterministic engine, not an AI wrapper promising realistic-looking noise or digging through your sensitive data. Everything resides and runs on your own servers. You can trust, inspect, and license what SpiceGrinder does on your terms.
Same model, same seed, same data — every single time. No sampling drift, no surprise rows, no re-runs that quietly diverge from the last one.
There’s no model guessing at your schema. But if you use agents then our plain-text domain models and a clean architecture mean agentic workflows can read, write, and drive SpiceGrinder directly.
SpiceGrinder never calls home. Nothing is required to run on our servers or anyone else’s cloud — it runs where your data already lives.
Start modeling and grinding real volumes of data without reaching for a credit card. The free tier is built to be actually usable, not a teaser.
One straightforward cost structure that scales from a single developer to a large organization — no hidden tiers, no sales calls required to see the number.
You understand your own data better than anyone. Model it with SpiceGrinder’s built-in tools, generate as much or as little data as you need, and use the outputs however you like.
Model your entities and the rules that connect them, simulating your real-world data with as much fidelity as you require. Use SpiceGrinder’s built in libraries or extend it with components you create that match your business rules and needs.
Generate as much data as you want, as often as you want — no limits. Every run is reproducible from the model, never from a copy of production.
You own the data, use it wherever you like. Export into environments, pipelines, sales demos, or partner sandboxes with no sensitive records to guard and no approval to chase. SpiceGrinder will never “call home” or send your data anywhere. It’s YOURS.
A few things people usually want to know before diving in to the grind.
Download the betaSpiceGrinder ships two ways — pick whichever fits how you work.
The bundled runtime means there’s nothing else to install.
A smaller, cross-platform download for environments that already manage their own Java runtime.
Either way: no GPU or other special hardware required.
Nothing. The beta release is SpiceGrinder Free, so it wouldn’t cost anything anyway. If you like what you see, contact our sales team to register interest in early access to SpiceGrinder Pro.
We don’t have a fixed date yet. We’ll stay in beta release until we’re comfortable we have sufficient feedback to be confident in an official release. We may choose to release SpiceGrinder Pro on an early-access basis before a public rollout, so let us know if you want to be first in line.
No. You describe the shape of your data in a model, and SpiceGrinder generates from that description — no production export, snapshot, or database connection required at any point.
