What the publisher says

From the Triplex schema contracts repository's README, as published. We do not edit it. Read it on GitHub

Triplex

Local-first data privacy tooling for two jobs: masking a real table, and generating a synthetic one that behaves like it. Around them sit schema contracts, privacy-risk scoring and drift checks. Everything runs inside your own perimeter: on your machine, in your CI, or in your browser through WebAssembly.

Your data stays with you

Triplex does not send your data anywhere. There is no server, no upload and no telemetry. Datasets, identifiers, mapping files, credentials and profiling outputs stay where you run the tool. The web UI reads your file inside the browser tab and never transmits it.

What is in the box

All products share one Rust engine with Arrow-compatible data contracts.

When Faker is not enough

Faker and similar libraries invent each value on its own. That works for a name in a form field, not for tests, demos or models that depend on how columns relate. triplex synthesize fits a model to a real table on your machine and samples new rows that keep the correlations between numeric columns and, with the Bayesian network, the dependencies between categories. Two limits: it needs a real table to learn from, and it drops identifier-like columns instead of imitating them, so mask those or fill them with a fake-value generator.

What the output is, and is not:

states what was measured and what is not covered.

  • Pseudonymized output is still personal data. The mapping file can reverse it.
  • Synthetic output carries no privacy guarantee by default. Every run writes a report that

review.** Treat its guarantee as unverified until that review is published.

  • **The differentially private mode is implemented and tested, and is awaiting independent
  • ModelCard reports are not a conformity assessment.

Quick start

Install the triplex command from crates.io (needs a stable Rust toolchain), or skip the toolchain and use the Docker image. The examples use the synthetic fixtures in tests/fixtures/ of this repository.

cargo install triplex
triplex --version

# Or, from a checkout of this repository: build the binary into target/release/
cargo build --release -p triplex
alias triplex=target/release/triplex
