Feature Flags Infrastructure

Deploying code and releasing features should be independent events. Anubiz Engineering sets up feature flag infrastructure that gives you granular control over feature rollouts — percentage-based targeting, user segment targeting, kill switches for emergencies, and the observability to measure impact.

Start a Brief

Flag Evaluation Architecture

We deploy server-side flag evaluation using LaunchDarkly, Unleash, or Flagsmith — depending on your budget and self-hosting preference. Flags evaluate locally with cached rulesets for zero-latency decisions. SDK integration into your backend and frontend ensures consistent flag state across the stack. Evaluation events stream to your analytics pipeline for rollout monitoring.

Progressive Rollout Strategy

New features roll out incrementally: 1% of users, then 5%, 10%, 25%, 50%, 100%. At each stage, you monitor error rates, performance metrics, and business KPIs. If anything degrades, you dial back instantly. We configure targeting rules that can segment by user ID, geography, plan tier, or custom attributes — so you can test with internal users first, then beta cohorts, then general availability.

Emergency Kill Switches

Every major feature gets a kill switch. When a new payment flow causes failures, toggling one flag disables it instantly — no deploy, no rollback, no downtime. Kill switches propagate within seconds through streaming connections. We set up flag-change alerts so the team knows when flags are toggled in production, with audit logs showing who changed what and when.

Flag Lifecycle Management

Stale flags are technical debt. We set up flag lifecycle policies: temporary flags (feature rollouts) get an expiration date and generate cleanup tickets when the rollout is complete. Permanent flags (kill switches, plan-gated features) get documented and reviewed quarterly. A dashboard shows total flag count, stale flags, and flag evaluation frequency to prevent flag sprawl.
