Free GitHub Action. Comments on every PR with stale-flag findings. Works with 13 languages and every flag SDK.
Every team with 50+ flags has a graveyard. Hardcoded trues nobody dares delete. Dead else-branches that were "temporary" 18 months ago. Experiment flags from products you sunset.
You don't notice it until you're three sprints into a refactor and someone says "wait, is legacyCheckout even on?" Then a junior dev removes it. Then production breaks at 3am.
FlagShark watches your repo continuously. Every PR gets a comment. When a flag is ready to retire, its cleanup PR is one click away. No quarterly cleanup sprint that never happens.
Median end-to-end on repos under 100k LOC: 4.2s · large monorepos take longer; the comment posts the moment the scan finishes
Nothing new for your team to learn. No browser extension. The PR comment is the entire interface: every stale flag, every staleness reason, every "open the removal PR" link, inline on the PR your team is already reviewing.
What this means in practice: the cleanup conversation happens in the same place as the feature conversation. No context switch.
One screen for every repo you've connected: flag health, stale flags ranked by how long they've waited, every cleanup PR from opened to merged. The view an eng lead opens before sprint planning.
Three questions, answered in seconds: what got cleaned up, what's queued next, and is every repo covered? That's the dashboard's whole job.
FlagShark posts to your team's Slack when a flag goes stale or a cleanup PR opens — event-based, not on a timer. The weekly roundup of what got merged and what's still outstanding arrives as an email digest.
What this won't be: a notification firehose. You hear from Slack when there's something to act on.
