Head-to-head
LaunchDarkly vs Statsig: which one in 2026?
LaunchDarkly is a feature management platform from Catamorphic, Co. that has expanded into experimentation, observability and AI agent controls, and Statsig is an experimentation and product analytics platform with feature flags. The main difference is how each one is metered and which side leads.
Verdict
LaunchDarkly sits first because release control is its core, the free tier is workable and its certifications are on the page. Statsig is the better pick when experimentation and analytics drive the decision, and its free plan is more generous on events. Before choosing Statsig, resolve the ownership question: its footer and terms name different entities, and its security page was unavailable when checked. The headline prices are not directly comparable, since one bills per service connection and the other by events, so model your own traffic first.

Frequently asked questions
Does LaunchDarkly have a free plan with unlimited flags?
Yes. The Developer plan costs $0 with no credit card, unlimited seats and unlimited flags. It is capped at 5 service connections, 1K client-side MAU, 1 project, 3 environments and 14 days of data retention, and ingestion stops at the 5K AI run limit.
How does Statsig charge once I outgrow the free plan?
Pro costs $150 per month and includes 5M events, then $0.05 per 1K events. It also raises session replays to 100,000 per month and makes analytics retention unlimited. Each Pro subscription covers one project, which matters for teams with several products.
Is Statsig now part of Amplitude?
The pages opened do not settle it. Statsig's terms name Amplitude, Inc. as the party called Statsig, its privacy URL redirects to Amplitude, yet the footer says Statsig, LLC. We could not confirm the current corporate entity, so verify it before signing.
Which one supports evaluating LLM and AI agent behavior?
LaunchDarkly lists AgentControl with online and offline evals, custom judges, LLM traces and agent observability, and the Developer plan includes 5K AI runs. The Statsig pages we opened did not describe an equivalent agent control feature, so confirm directly if that is a requirement.
