The Problem
Sound familiar?
LaunchDarkly and Flagsmith are powerful but overkill and expensive for small teams
Hardcoded feature flags in git require a deployment to toggle — risky and slow
Rolling out to 10% of users requires custom code that most teams rewrite every project
The Solution
Lightweight Feature Flags fixes this.
Instant Feature Toggles
Create a flag in 10 seconds, call `/flag/:key` from any language, get a boolean back. No SDK required.
Percentage Rollouts
Roll out to 5%, 25%, 50%, or 100% of users with consistent assignment via user ID hashing.
Segment Targeting
Target by plan tier, country, email domain, or any custom attribute you pass in the request.
How It Works
Set up in under 2 minutes. No complex configuration.

Frequently Asked Questions
What is the evaluation latency?
Flag evaluations are served from edge nodes globally with p99 latency under 10ms.
Is there an SDK or is it pure HTTP?
Pure HTTP by default — one GET request returns the flag value. Optional JS and Python SDKs available for convenience.
