Understand How Your Flags Perform
Track every flag evaluation across your environments. Spot stale flags automatically, monitor rollout adoption in real-time, and debug SDK state with built-in developer tools — all without impacting performance.
The Problem with Unobservable Feature Flags
Feature flags without analytics are a black box — you ship features but never know if they land
Flying Blind on Flag Usage
You have dozens of feature flags in production but no idea which ones are actively being evaluated, how often, or whether your rollout is actually reaching users.
Stale Flags Pollute Your Codebase
Old flags pile up in your code. Nobody knows which are safe to remove. Every stale flag is tech debt—adding complexity, slowing onboarding, and increasing risk.
No Visibility Into SDK State
A user reports they can't see a feature. Is the flag loaded? Is their context correct? Without tooling to inspect live SDK state, debugging is guesswork.
Complete Visibility Into Your Feature Flags
Flagpool tracks every flag evaluation automatically — giving you real-time insight into adoption, usage trends, and which flags are ready to retire. Built into the SDK with zero performance impact.
Evaluation Analytics
Track how often each flag is evaluated, per environment, aggregated daily. See usage trends over time, spot spikes during rollouts, and confirm kill switches are firing during incidents — all from your dashboard.
SDK Debug Tools
Inspect live flag state, analytics buffers, and user context directly from the browser console or programmatically in any SDK. Debug targeting mismatches, verify rollout percentages, and confirm analytics are flowing — without third-party tools.
Automatic Stale Flag Detection
Flagpool continuously monitors evaluation activity and automatically surfaces flags with zero evaluations over a configurable window. Instead of manually auditing your codebase, you get a clear list of flags that are safe to remove — keeping your code clean and your flag inventory lean.
Analytics & Debugging Features
Everything you need to observe, understand, and maintain your feature flags
Usage Trends Over Time
Track flag evaluation counts over days, weeks, and months. Spot adoption curves during rollouts and confirm features are reaching your users.
Automatic Stale Flag Detection
Flags with zero evaluations are automatically surfaced for cleanup. Stop guessing which flags are safe to remove — Flagpool tells you.
Per-Environment Breakdowns
See evaluation counts broken down by environment. Understand how flags behave differently across dev, staging, and production.
SDK Debug Console
Inspect flag state, analytics buffers, and user context from the browser console via __FLAGPOOL__ or programmatically in any SDK.
Zero-Latency Collection
Analytics are batched in memory and flushed asynchronously. Flag evaluation performance is never impacted — your app stays fast.
Export & Reporting
Export analytics data as CSV or JSON for custom reporting. Integrate with your existing dashboards and monitoring tools.
