Show HN: FlagShark – Automatically removes stale feature flags via PRs

Hacker News - Sat, 06/14/2025 - 12:53pm

Hey HN! I'm building FlagShark to solve feature flag tech debt automatically. It's a GitHub app that not only tracks feature flags, but actually creates pull requests to remove them when they go stale.

The Problem: We all use feature flags, but they accumulate forever. Knight Capital lost $460M in 45 minutes due to a reused stale flag. Every team I've worked with spends 3-5 hours/week per developer managing technical debt, or worse, leaves them to accumulate. The industry does 20 trillion flag evaluations daily, yet most flags are never cleaned up.

How it works: - Monitors your repos for feature flags using AST parsing - Tracks flag lifecycle across pull requests - When flags go stale, automatically creates PRs to remove them - You review and merge - or ignore if the flag is still needed

The magic: You keep shipping features while FlagShark handles the cleanup. No more quarterly "flag cleanup sprints" or tech debt accumulation.

Currently supports Go, TypeScript/JavaScript, and Python. Detects LaunchDarkly, Unleash, Split.io, Flipt, and custom implementations.

Looking for beta testers! Free access for early users who can provide feedback:

- How stale should a flag be before suggesting removal? - Should it create one PR per flag or batch them? - What safety checks would make you confident auto-merging? - Which feature flag libraries does your team use?

If you're interested, comment here or sign up on the site. Let's eliminate flag debt together.

What Are the Most Underrated Tools You Use Every Day?

Hacker News - Sat, 06/14/2025 - 11:50am

Everyone talks about VS Code or Docker, but I’m more interested in the small, niche, or overlooked tools that quietly improve your workflow.

For me, it's:

fzf for fuzzy finding in the terminal

ripgrep instead of grep

tldr for fast command help
