Combine advanced feature flagging and monitoring with powerful built-in experimentation in a single, user-friendly platform. Easily run A/B tests, multi-variant tests, measure real-time impact, and refine your releases with data-driven insights.
Protect sensitive data using an in-memory decision engine, which runs feature evaluations on the client, maximizing privacy and speed. No user data ever leaves your application, making it easier to comply with even the strictest privacy regulations.
Harness offers a transparent pricing model that scales cost-effectively with your usage, so you can budget confidently and invest in future innovations—without worrying about monthly overages, hidden fees, or costly surprises.
LaunchDarkly is a widely recognized feature flag tool, however it falls short for fast-moving development teams who want to do more experimentation (A/B testing) to make data-informed decisions. In contrast, Harness Feature Management & Experimentation merges advanced feature flags, built-in measurement, and secure client-side evaluations into a single, user-friendly platform that cost-effectively scales.

Empower product teams to release new features, schedule when releases should happen and guarantee your customers the best experience possible.
Choosing the right feature management and experimentation platform shapes your product’s success—which is why we see so many organizations moving from LaunchDarkly to Harness Feature Management & Experimentation. While LaunchDarkly is a common feature flagging tool, many teams quickly run into escalating costs, hidden complexity, and data security concerns. Harness FME flips the script: our intuitive interface, robust experimentation capabilities, transparent pricing, top-notch support, and on-device data evaluation make us a smarter, safer, and more agile choice.
LaunchDarkly’s experimentation features often require third-party integrations to get deep, meaningful insights. Harness FME bundles powerful analytics directly into your feature management workflow, making data-driven decision-making simple and immediate.
A frequent complaint among LaunchDarkly users is the unpredictable price hikes at higher usage tiers. Harness FME offers clear pricing models that scale with your organization, ensuring you always know what you’re paying for.
LaunchDarkly’s server-side evaluations often involve sending user or other private data to external servers, raising privacy and compliance flags. Harness FME offers an on-device (or on-premise) evaluation model, letting you maintain complete control over sensitive information.
Many LaunchDarkly users—particularly Product Managers—struggle with an interface designed primarily for developers. Harness FME focuses on clarity, enabling every stakeholder to create, monitor, and disable feature flags independently, with no code required.
Although LaunchDarkly’s documentation is extensive, some teams find it dense and slow to navigate. Harness FME combines succinct, role-based onboarding with dedicated support, so your teams master the platform quickly and can rely on fast help when it matters.
Harness Feature Management & Experimentation is designed to tackle the exact challenges teams face with LaunchDarkly—whether it’s UI complexity, opaque costs, limited experimentation, or privacy concerns. By blending intuitive workflows, powerful analytics, straightforward pricing, hands-on support, and secure data handling, Harness offers the complete solution you need to deliver winning features, faster and smarter.
