Feature Flags Plugin

A simple, self-hosted feature flag store backed by PostgreSQL. Toggle features on and off for specific users, groups, or rollout percentages — no third-party service required.

Overview

• Boolean Flags — on/off per flag, globally or per-environment
• User Targeting — enable a flag for specific user IDs or email patterns
• Percentage Rollouts — gradual rollout by user cohort
• SDK-Compatible API — REST endpoint compatible with OpenFeature-style clients
• Admin UI — manage flags through the nSelf Admin panel
• Cache-Friendly — flags cached in Redis (when Redis is enabled)

Installation

nself plugin install feature-flags

nself plugin status feature-flags

Usage
