Start building before you talk to us

Start building before you talk to us

Use the docs, SDK, and examples to build a first private workflow

Build first. Talk when the boundary is real.

Give technical visitors a real next step

Explore the language, VM, and SDK first. Bring us the product boundary when you have one.

Familiar Code Patterns

Same Flower interface you're already using—just point to our aggregator endpoint.

Local Simulation

Test your aggregation logic on your machine before running multi-party.

Clear Error Messages

No cryptic protocol failures—actual debugging information when something goes wrong.

Flexible Privacy Controls

Add differential privacy and gradient clipping where you need it; skip it where you don't.

Honest About Tradeoffs

MPC adds computation time. We're upfront about performance characteristics so you can decide if the tradeoff works.
