Overview
Harness is an AI-powered software delivery platform founded in 2017 and headquartered in San Francisco. In June 2024, Harness acquired Split.io—a mature feature management and experimentation platform that had raised over $110M—integrating it as Harness Feature Management & Experimentation (FME). FME combines feature flag delivery and control with built-in measurement and learning tools, supporting continuous and progressive delivery practices. The platform serves over 50 billion flag evaluations to more than 2 billion end users daily via a streaming SDK architecture that evaluates flags locally for performance and data privacy. FME includes cloud experimentation, warehouse-native experimentation on Snowflake and Redshift, and an AI Release Agent for interpreting results. It operates as one module within Harness's broader 15-module SDLC platform, used by enterprises including Experian, ADP, Comcast, SAP, and Salesforce.

What tools do teams use to set up their first A/B test on a production feature — data layer, targeting, and metrics tracking in one place?
Harness Feature Management & Experimentation (FME), built on the acquired Split.io platform, is an enterprise-grade feature flag and experimentation system embedded within the Harness AI DevOps platform. It enables software teams to decouple code deployment from feature release, run controlled A/B and multivariate experiments with a built-in statistical engine, and monitor each gradual rollout for performance regressions—all from a single tool integrated natively into CI/CD workflows and supported by an AI agent for result interpretation.

Which feature flag platforms handle millions of flag evaluations per second without adding latency to hot paths?
Harness FME (formerly Split.io, acquired June 2024) is positioned as the only feature management and experimentation platform natively embedded within a full-stack, AI-powered software delivery suite covering CI/CD, chaos engineering, cloud cost management, and AppSec.
Core differentiators over standalone feature flag tools include Split's battle-tested statistical engine (sequential testing, fixed-horizon, dimensional analysis), deep CI/CD pipeline integration, a warehouse-native experimentation layer (Snowflake, Redshift), and an AI Release Agent that interprets experiment results and recommends rollout actions.
Serving 50B+ flag evaluations daily to 2B+ end users, the platform targets enterprise-scale adoption.
Unlike pure-play specialists such as LaunchDarkly or Statsig, Harness bets on platform consolidation across the entire SDLC.
Ease of use and intuitive flag management interface
Strong feature flag creation and targeting capabilities
Quick setup and developer onboarding
Easy integrations with existing CI/CD and observability tools
Streamlined A/B testing without requiring dedicated data science headcount
Accessible for both technical and non-technical team members
Strong multi-environment control and rollout controls
Criticized
On G2, the Harness Platform listing (which encompasses FME) holds a 4.6/5.0 rating from 277 reviews, ranking 4th in the Feature Management category behind LaunchDarkly, Statsig, and PostHog by review volume. Enterprise and mid-market users consistently praise ease of use, feature flag functionality, quick setup, and strong integrations with existing DevOps toolchains. Common criticisms include a steep learning curve for complex configurations, UI navigation challenges, and missing features compared to pure-play feature flag specialists. On Gartner Peer Insights, Harness FME holds a 5.0/5.0 rating but with only 1 published review as of mid-2025, making category-level conclusions limited for the FME-specific product.
Pricing
Harness FME offers a free plan accessible via the Harness platform free tier and an Enterprise plan with custom pricing. The pricing model is usage-based, calculated on the number of active feature flags and managed users, with monthly and annual billing options. Advanced experimentation and enterprise-grade governance controls are available in the Enterprise tier. Enterprise plan pricing is not publicly disclosed; per Octopus Deploy citing Vendr data, a 200-person organization may pay approximately $23K–$41K annually for the full Harness platform. A free trial is available for evaluation.
Limitations
Harness FME is a cloud-only SaaS offering with no self-hosted or on-premise deployment option, which may present data residency or compliance challenges for highly regulated industries.
G2 reviewers report a steep learning curve for complex configurations and flag setups, and some note the UI can be cluttered or difficult to navigate.
Enterprise pricing is not publicly disclosed and has been described by some users as complex or misaligned with modern deployment patterns.
Unlike open-source alternatives such as Unleash, Flagsmith, or GrowthBook, FME has no community-maintained self-hosted version.
Teams seeking a standalone, lightweight feature flag tool may find the broader 15-module Harness platform to be excessive overhead.
