Keep your LaunchDarkly investment. Add automated code cleanup with FlagShark. Complete your feature flag lifecycle.
Control flag targeting, percentage rollouts, and kill switches from a centralized dashboard. Manage who sees what, when.
Automatically detect stale flags and generate PRs to remove them from your codebase. Clean up the code LaunchDarkly can't touch.
LaunchDarkly is an excellent feature flag management platform. Here's where it excels.
Single dashboard to create, configure, and manage all your feature flags across environments.
Sophisticated targeting by user attributes, segments, and percentage rollouts for controlled releases.
Instantly toggle features off in production without deploying code. Critical for incident response.
Complete audit trail of who changed what flag and when. Essential for compliance and debugging.
Role-based access control, approval workflows, and team permissions for enterprise-scale operations.
SDKs for every major language and framework with excellent documentation and support.
LaunchDarkly detects stale flags in their platform. But removing them from your code is still manual.
LaunchDarkly identifies stale flags, but stops there—you still need to manually find and remove flag code from your codebase.
FlagShark: Turns stale flag detection into action with automated PRs that remove the code.
Archiving a flag in LaunchDarkly doesn't touch your code. Someone still has to manually remove the flag checks.
FlagShark: Creates ready-to-merge PRs that remove flag code completely.
LaunchDarkly has no visibility into your code structure. It can't know how flags are wrapped or nested.
FlagShark: Uses tree-sitter to parse your code and remove flags cleanly.
LaunchDarkly is a separate UI from your development workflow. Context switching slows teams down.
FlagShark: Lives in GitHub with PR comments and automated workflows.
LaunchDarkly tracks flag evaluations, not cleanup progress or technical debt reduction.
FlagShark: Dashboard shows cleanup velocity, debt reduction, and flag age.
LaunchDarkly only manages LaunchDarkly flags. Custom flags or other providers are invisible to it.
FlagShark: Works with LaunchDarkly, Unleash, Split, custom flags, and more.
Different tools for different phases of the flag lifecycle
| Capability | LaunchDarkly | FlagShark |
|---|---|---|
| Flag targeting & rollouts | Not applicable | |
| Kill switches | Not applicable | |
| Stale flag detection | ||
| Automated cleanup PRs | ||
| Code-level flag removal | ||
| GitHub-native workflow | ||

| Dashboard & analytics | Flag state | Cleanup metrics |
LaunchDarkly handles phases 1-4. FlagShark handles phases 5-7.
LaunchDarkly charges based on Monthly Active Users (MAU) and flag evaluations. Every time your code checks a flag, that's a billable event.
More flags in your codebase means more evaluations means higher revenue for LaunchDarkly. Building a tool that helps you remove flags from your code would directly reduce their billing metrics.
This isn't a criticism—it's just business reality. That's why cleanup needs to come from a neutral third party.

The flag is now "always on" — time to remove it from code
Automatic detection based on LaunchDarkly state + code analysis
AST-based removal preserves the "on" branch, removes flag checks
Code is cleaner, LaunchDarkly flag can be safely archived
FlagShark enhances your LaunchDarkly investment—no changes needed
FlagShark works alongside LaunchDarkly, not instead of it
Connect to LaunchDarkly for enhanced detection, or work codebase-only

Fewer stale flags = fewer evaluations = lower costs
No. FlagShark complements LaunchDarkly. LaunchDarkly handles flag targeting, rollouts, and kill switches. FlagShark handles the cleanup phase—detecting stale flags and generating PRs to remove them from your code. They're different tools for different phases of the flag lifecycle.
It's optional but recommended. Connecting to LaunchDarkly allows FlagShark to check flag states and identify flags that are always-on or archived. Without the connection, FlagShark still works by analyzing your codebase for flags that appear stale based on usage patterns and commit history.
No. FlagShark only targets flags that are confirmed stale—either always-on for 30+ days (configurable), archived in LaunchDarkly, or matching your custom staleness criteria. Every removal is proposed as a PR for human review, not auto-merged.
FlagShark handles both. Configure your LaunchDarkly SDK patterns and any custom flag implementations in your .flagshark.yaml file. FlagShark's provider-agnostic approach means it detects and cleans up all your flags, regardless of source.
LaunchDarkly charges based on MAU (Monthly Active Users) and flag evaluations—costs scale with your traffic. FlagShark uses flat monthly pricing based on repository count, so costs stay predictable. Better yet, FlagShark actually helps reduce your LaunchDarkly bill by removing unused flags that generate unnecessary evaluations.
LaunchDarkly got your flag to 100%. Let FlagShark remove it from your code.
