The platform

Four capabilities. One job: retire the flags.

FlagShark does one thing: scan your repo, then propose the cleanup PR. Everything below is built on that single move, the capabilities that make cleanup automatic at team and org scale.

01Detection

AST-based across 12 languages.

Tree-sitter WASM grammars parse your code into a real syntax tree. We match flag SDK calls structurally. No regex, no false positives from comments or strings. Works with LaunchDarkly, Statsig, Split, ConfigCat, Flagsmith, Unleash, PostHog, OpenFeature, and any custom flag pattern.

· Tree-sitter WASM· 12 languages· 8+ flag SDKs· Custom flags via YAML

02Automation

One-click PRs that retire flags.

Click a finding, FlagShark opens a separate PR that removes the dead else-branches, deletes the SDK call sites, removes orphan helper functions, updates affected tests. Your CI runs. You review in 30 seconds. We never auto-merge.

· Cleanup PRs· Scheduled policies· Bulk operations· Safe removal

03Analytics

Cleanup velocity, not vanity counts.

Health scores 0-100 per repo. Age distribution charts. Weekly trends. The number that matters: MAER (Monthly Active Engaged Repos), repos where a FlagShark PR comment was acted on in the last 30 days.
