Overview
LaunchDarkly, founded in 2014 by Edith Harbaugh and John Kodumal, pioneered feature flags as a hosted service, letting engineering teams toggle features, roll out to segments, and roll back instantly without redeploying code.
The platform has since expanded from CodeControl (traditional feature flag management) into AgentControl, a companion product for governing AI agent and LLM behavior in production.
Key Features
Core capabilities include unlimited feature flags, user/account/device targeting, A/B testing and experimentation, session replay, and SDKs for roughly 30 languages and frameworks.
AgentControl extends the same runtime-control model to AI features, tracking 'AI runs' and enabling kill-switches, guardrails and staged rollouts for LLM-powered functionality.
Pricing
A free Developer plan offers unlimited seats and generous flag, log and AI-run limits with no credit card required, making LaunchDarkly accessible to small teams and individual developers.
Paid tiers - Foundation, Enterprise and Guardian - add SSO, release automation, advanced targeting, compliance certifications and automated release monitoring as organizations scale.
Key Features
Feature flag management — Toggle features, roll out to targeted user segments, and instantly roll back without a code redeploy.
A/B testing and experimentation — Run controlled experiments tied directly to feature flags to measure impact before full rollout.
AgentControl for AI features — Governs AI agent and LLM-powered feature behavior in production, tracking AI runs and enabling kill-switches and guardrails.
Broad SDK support — SDKs available for roughly 30 languages and frameworks for both server-side and client-side flag evaluation.
Session replay and observability — Session replay and error tracking help teams understand user impact of flagged releases.
Release automation and approvals — Enterprise tiers add scheduling, approval workflows and audit logging for regulated release processes.
Automatic rollback (Guardian) — Guardian tier monitors guardrail metrics and can automatically pause or roll back risky releases.
Single sign-on and SCIM — Foundation and above add SSO, with Enterprise/Guardian adding SAML/SCIM for identity governance.
