Twelve languages. One detection engine.

TypeScript

JavaScript

Python

Rust

Java

Kotlin

Ruby

PHP

Objective-C

All detection is AST-based via tree-sitter. No regex, no false positives from comments or strings.

Flag providers

Eight providers, pre-tuned.

LaunchDarkly

BoolVariation, StringVariation, AllFlags, Track

Split.io

getTreatment, getTreatments, track

Unleash

isEnabled, getVariant, getAllToggles

GrowthBook

isOn, getFeatureValue, evalFeature

PostHog

isFeatureEnabled, getFeatureFlag, getAllFlags

ConfigCat

getValue, getValueDetails, getAllKeys

Flagsmith

has_feature, get_value, get_trait

Statsig

checkGate, getConfig, getExperiment

Need a provider we don't list? Define custom flag patterns in .flagshark.yaml (regex or AST patterns both work).
