Feature Flags & Config

Overview

Power-Rent uses a comprehensive feature flags system to control feature rollouts, manage paid functionality, and support database migrations. The system integrates multiple providers and identification strategies.

Architecture

Primary Providers:

• Statsig via statsig-node-lite (server) and @flags-sdk/statsig adapter
• flags/next for Next.js integration
• feature-gate custom library for plan-based paid features

User Identification:

• Stable ID system using cookies for consistent flag evaluation
• Identity payload feeds into Statsig for targeting

Key Flag Categories:

• Infrastructure flags (postgresEnabled)
• Migration flags (entity-by-entity Fauna → Postgres migration)
• Product/feature flags (customersExport, etc.)
