Works with your stack.

Thirteen languages, syntax-aware detection: tree-sitter AST for TypeScript, JavaScript, Go, Python, and Java, precise regex patterns for the rest. Eight flag providers with SDK-aware detection. Custom flag patterns via .flagshark.yaml for anything we haven't pre-tuned.

Languages

Thirteen languages. Syntax-aware detection.

TypeScript

JavaScript

Python

Rust

Java

Kotlin

Ruby

PHP

Swift

C++

Objective-C

TypeScript, JavaScript, Go, Python, and Java parse to a full tree-sitter AST; the other eight use precise regex patterns. Either way we match flag SDK calls by structure, so you get far fewer 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).

CI & GitHub

Drops into your existing pipeline.

→GitHub App with minimum read-only permissions (no source code ever stored).
→GitHub Actions workflow: 8 lines of YAML, runs on your CI minutes.
→PR comments inline with detection results, no separate dashboard required.
→Slack alerts when a flag goes stale or a cleanup PR opens; the weekly roundup is an email digest.
→API access for custom dashboards or org-wide policies.

Probably already supports your stack.
