React

Experimentation

Ship experiments. Read conclusions.

Assign users to experiment variants using a deterministic hash of projectId, experimentId, and userId — no flicker, no inconsistent experiences across sessions for the same userId. Every assignment is logged with the experiment version and variant, so results are always reproducible.

Core Capabilities

Deterministic Variant Assignment

Users are bucketed by a stable hash of projectId + experimentId + userId. When the same userId is available, the same variant is always assigned.

Sticky Allocation

Variant assignments persist for the experiment lifetime. Changing traffic weights does not re-bucket existing participants.

Full Assignment Audit

Every assignment is logged with experiment ID, variant, and timestamp. Replay any experiment result at any point in time.

Reach. React. Reward. Return.

Let every ad dollar return like the tide.
