Manage Feature Flags, Measure What Matters
Release with feature flags connected to critical impact data, and always know whether your software changes are making things better or worse.
Release. Monitor. Experiment.
This is more than a toggle. It’s a shift toward safer, faster rollout practices.
Feature Management
Ship 50x faster with less friction and fear
Feature Flags
Speed up software delivery by deploying code in production without releasing it to customers. Then, safely test, target, and turn features on/off with effortless controls.
Flexible Targeting Rules
Whether you’re gradually rolling out features to a defined set of customers, or conducting beta tests to a random sample of users, Harness lets you customize who sees what and when.
Dynamic Configurations
Control components of your software features without deploying new code. This empowers entire teams to iterate in real-time with little risk of breaking things.
Release Monitoring
Automate issue detection, triage in under 1 minute.
Auto-Capture Performance Metrics
The moment you start a gradual release with a feature flag, out-of-the-box metrics automatically track performance issues and errors caused by each flag.
Detect the Impact of Progressive Delivery
Catch release issues most monitoring tools miss. Harness quickly detects the impact of each individual feature, even when multiple features are rolled out to small fractions of users at the same time.
Instant Alerts & Actions
As soon as a gradual release causes an impact on system performance or user behavior, you'll be alerted to take action.
Experimentation
Test, learn, and iterate efficiently to deliver more impactful products with less toil.
A/B Tests and Beyond
Once you’re measuring guardrail metrics for safer releases, experimentation infrastructure is already in place. Easily run A/B tests with the same self-service tool. No additional resources or complexity required.
Centralize Experiments to a Single Source of Truth
Eliminate fragmented islands of experimentation with competing methodologies and levels of rigor. Replace them with a scalable and proven solution built for engineering teams.
Make Bold Bets Safely
Reduce the risk and impact of a “failing” experiment. Establish the psychological safety your teams need to confidently make bold bets.
Built for the Enterprise
Architected for speed, security, and resiliency

We suit your stack
Ingest events from customer data, performance monitoring, and error tracking systems to power alerts and experiments. Import data from Google Analytics, mParticle, Segment, Sentry. Export data to Datadog, Jira, New Relic, Sumo Logic.
“This provides so much more than just a toolset change. You know, It sounds simple, feature toggles, but it’s transformative in nature. It’s transformative for the teams in terms of the culture we adopt.”
“Split makes it possible to really understand how our users respond to the changes we make. Now it’s easy to know the best change for our users and how we can help them satisfy their creative journey.”
“Previously, we'd see a 20%-40% increase in support cases, issues & questions during the first 2 weeks of a code release. With Split, that's been basically minimized to no incidents. Support costs have been drastically reduced.”
“People would quit if we stopped using Split. The psychological safety comes up in annual reviews.”
