Eppo vs LaunchDarkly

Quote on request

From $12 per seat/month plus context-based usage (indicative)

Quote-based, generally aimed at companies with a data team and a warehouse already in place.

Priced on seats plus monthly contexts (roughly, unique users evaluated). High-traffic consumer products get expensive.

Free tier available for small teams.

14-day trial; no permanent free tier.

• Statistically rigorous — sequential testing, CUPED and diagnostics are core, not add-ons.
• Metrics defined once in the warehouse and reused across every experiment.
• dbt integration fits existing analytics engineering workflows.

• Extremely reliable flag delivery with offline fallbacks — this is infrastructure you can trust in the request path.
• Best-in-class governance: approval workflows, audit logs, role-based access.
• Code references and stale-flag detection actually help you remove dead flags.

• Requires a warehouse and a data team; not usable by a product manager alone.
• Feature-flagging capability is lighter than dedicated flag platforms.
• Now part of Datadog, which changes the strategic picture.

• The most expensive option in the category by a distance.
• Experimentation is competent but less sophisticated than dedicated statistics platforms.
• No meaningful free tier for evaluation.

Data-mature organisations where experiment results must withstand scrutiny.

Engineering organisations where flags are critical infrastructure and governance is required.
