LaunchDarkly

Enterprise feature flagging — progressive rollouts, targeting, and kill switches

Experimentation 4.5 / 5 Starts ~₹1,700/mo Updated Feb 2026

Quick Verdict

LaunchDarkly is the gold standard for feature flag management — the infrastructure that lets engineering teams deploy code without releasing features, and product teams control feature rollout percentages, targeting rules, and kill switches without code deployments. For Indian Series B+ startups deploying multiple times per day, LaunchDarkly's reliability and SDK quality justify the premium. For earlier-stage teams or teams comfortable with open-source, GrowthBook (free, self-hostable) covers 80% of LaunchDarkly's feature flagging capability at zero cost. The Firebase Remote Config option covers basic boolean flags for free on mobile. LaunchDarkly earns its price tag when you need enterprise-grade targeting, audit trails, and SDKs that your engineering team trusts at scale.

What is LaunchDarkly?

LaunchDarkly is a feature management platform founded in 2014 in Oakland, California. It provides the infrastructure for feature flags — code-level toggles that separate feature deployment from feature release. Engineers merge code to production with the feature behind a flag set to "off". Product managers then control when to turn it on, for which users, and at what rollout percentage — all without another code deployment.

For Indian engineering and product teams, feature flags solve a critical problem at scale: the coupling of "code is deployed" and "feature is live". Without flags, every deployment is a release decision, every bug is a rollback, and every experiment requires an engineering cycle. With LaunchDarkly, engineering deploys continuously, product controls releases, and a bad feature gets turned off in 30 seconds instead of requiring a hotfix deployment.

LaunchDarkly is particularly valuable for Indian fintech and B2C apps deploying to millions of users: gradually rolling out a new payment flow to 1% → 5% → 20% → 100% of users while monitoring error rates, targeting a new feature to users in Karnataka before national rollout, or giving your QA team access to a feature in production without making it visible to customers.

Key Features

Progressive Rollouts

Release a feature to 1%, 5%, 20%, 50%, 100% of users in sequence — monitoring metrics at each stage. Automatic rollback rules trigger if error rate or latency spikes beyond a threshold. For Indian payment flows and KYC updates, this rollout control reduces incident risk dramatically.

Targeting Rules

Show features to specific users based on any attribute: user ID, email, plan tier, city, device type, app version, custom segments. Target internal team members, beta users, or enterprise clients with features before general availability. Build user segments in LaunchDarkly and re-use them across multiple flags.

Kill Switches

Turn off a misbehaving feature in production in seconds — no code deployment, no hotfix, no incident bridge call. The PM or on-call engineer can disable the feature directly from the LaunchDarkly dashboard. For Indian fintech teams where a payment bug at 2 AM needs immediate resolution, this is the most valuable feature in the entire platform.

Experimentation

A/B testing integrated with feature flags — assign users to variants and track metrics. Bayesian or frequentist statistical analysis built in. For Indian product teams running conversion experiments on checkout flows, LaunchDarkly's experiment layer eliminates the need for a separate A/B testing tool if you're already using flags for rollouts.

LaunchDarkly vs Alternatives — The Decision Guide

⚡ For most Indian startups under Series B

Free option: GrowthBook (open-source, self-hostable) + Firebase Remote Config for mobile flags. This covers 80% of feature flag use cases at ₹0.
Paid option that's 70% cheaper: Statsig — similar feature set to LaunchDarkly, free up to 1M events, significantly cheaper at scale.
LaunchDarkly is justified: When you have 50+ engineers, are deploying to millions of users, need enterprise-grade audit trails (regulated fintech), or when flag reliability is so critical that a 5-minute outage is a company-level incident.

Best For

  • Indian fintech teams at Series B+ deploying to millions of users needing kill-switch reliability
  • Engineering teams of 50+ where flag management overhead justifies a dedicated platform
  • Regulated Indian fintechs (RBI, SEBI) needing audit trails of which features were live when
  • Teams doing continuous deployment (10+ deploys/day) where manual release coordination breaks down
  • Products with enterprise clients needing per-customer feature control and permission models

Pricing

LaunchDarkly charges per seat (team member). USD billing — 18% GST reverse charge for Indian companies. No free tier for teams.

Starter

~₹1,700/mo

$20/seat/month for up to 5 seats. Unlimited flags, basic targeting, rollouts. Entry point for small Indian teams. At ₹1,700/month for 5 engineers, the productivity value from safer deployments usually justifies the cost within the first month.

Enterprise

Custom

Custom contract for large teams. Includes dedicated infrastructure, custom SLAs, and advanced compliance features. Relevant for large Indian banks, insurance companies, or Tier 1 fintechs where downtime cost exceeds tool cost by orders of magnitude.

💡 Consider Statsig first: Statsig offers comparable feature flagging + experimentation, free up to 1M events/month, and paid plans starting at $150/month for unlimited events. Most Indian Series A–B teams find Statsig covers their needs at 80% of LaunchDarkly's quality at a fraction of the price.

Pros and Cons

Pros

  • Most reliable feature flag platform — 99.99% SLA
  • Best SDK quality across 30+ languages and frameworks
  • Enterprise targeting — any attribute, complex rules
  • Full audit trail for regulated Indian fintech
  • Kill switches that work in under 200ms globally
  • Experimentation platform integrated with flags

Cons

  • Expensive — hard to justify pre-Series B for most Indian teams
  • USD billing + 18% GST reverse charge
  • No meaningful free tier to evaluate
  • Statsig offers 80% of value at much lower price
  • GrowthBook is free and sufficient for many use cases

Getting Started with LaunchDarkly

  1. Establish a flag naming convention before your first flag — LaunchDarkly flags accumulate fast. Without a naming convention, you end up with new-checkout, new_checkout_v2, checkout-redesign-test, and checkout-flow-experiment all potentially active simultaneously. Establish a standard: [team]-[feature]-[type] e.g., payments-new-checkout-rollout, growth-referral-experiment, ops-bulk-kyc-killswitch. Write this in your engineering handbook before creating any flags.
  2. Set default flag values for production safety — Every flag needs a safe default: what happens if LaunchDarkly is unreachable? Set your default to the safe/old behaviour — new features off, experimental flags returning control. Never set a flag's default to "new behaviour" — a flag SDK failure should always fall back to the known-good code path, not the experimental one. This is the most important production safety decision in your LaunchDarkly setup.
  3. Use targeting to build a canary group for every major feature — Create a "canary users" segment in LaunchDarkly: 10–20 internal team members and trusted beta users who always get new features first. Enable every new flag for this segment before any percentage rollout. Your canary group catches bugs with users who understand the product and can provide immediate feedback — before the change reaches real customers. This pattern alone prevents the majority of production incidents related to feature releases.
  4. Connect LaunchDarkly to your observability stack — Integrate LaunchDarkly with Datadog, New Relic, or your monitoring tool so that flag changes are visible as events on your metrics dashboards. When you toggle a flag from 5% to 20% rollout, you want to see any correlated latency, error rate, or conversion changes in the same dashboard. Without this integration, correlating a metric degradation to a flag change requires manual investigation — with it, the connection is instant.
  5. Create a flag lifecycle process — flags must be cleaned up — Flags that outlive their purpose become technical debt: dead code wrapped in flag evaluations that nobody is confident removing. Implement a monthly flag audit: any flag that has been 100% on or 100% off for more than 30 days should be scheduled for removal. Assign flag ownership at creation (the team that creates a flag is responsible for removing it). Teams that skip flag cleanup end up with hundreds of permanent flags that slow SDK initialisation and confuse new engineers.
