Smpl Flags

Control feature rollouts across environments with type-safe flags and targeting rules.

Core

Type-safe flags, predictable evaluation

STRING, BOOLEAN, NUMERIC, and JSON types — each with a closed set of allowed values declared up front. Disabled flags serve the default as a zero-risk kill switch. First-match-wins rules make behavior easy to reason about.

Targeting

Target anything with JSON Logic

Rules are valid JSON objects, not string DSLs. Easy to build visual editors on top of, with library support in every major language. Scope rules per environment — different targeting for dev vs. prod, all in one flag.
