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
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.
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.
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.
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.
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.
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.
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.
Eliminate fragmented islands of experimentation with competing methodologies and levels of rigor. Replace them with a scalable and proven solution built for engineering teams.
Reduce the risk and impact of a “failing” experiment. Establish the psychological safety your teams need to confidently make bold bets.

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.”
