Split

Overview

Split combines feature flag management, gradual release monitoring, and experimentation analytics for engineering and product teams. It suits teams that need to control how changes reach users and measure their business effects. The free edition is a useful starting point, but its single workspace and two-environment ceiling make it a narrow fit as teams grow.

Key features

Teams can create, target, and manage feature flags to control releases. That makes Split a practical choice when rollout decisions need to happen at the feature level, with the ability to manage exposure rather than ship every change to everyone at once. Release monitoring watches gradual rollouts for changes in system performance and user behavior, and alerts identify the flag associated with an issue. This links release control to operational feedback; teams that only need monitoring may find the wider feature-management and experimentation platform more than they need.

Real-time experimentation analytics measure how feature changes affect business outcomes. For product teams evaluating changes as they roll out, that brings measurement into the same platform as release control. JavaScript, iOS, Android, and common backend SDKs give engineering teams several implementation options. The Admin API can create, edit, and delete flags through HTTP requests, which is useful for teams that want to manage flags programmatically.

Integrations include Slack, Jira Cloud, Azure DevOps, Datadog, New Relic, Segment, Amplitude, and Amazon S3, spanning collaboration, development, monitoring, analytics, and storage tools. Split says targeting data stays in the customer's environment rather than being sent to Split. Its compliance program information is organized on the Harness Trust Center, and the company says Split is now part of Harness.

Pricing

Free Edition (Developer): free. It includes one workspace, two environments, two treatments per flag, and segments limited to 10,000 keys. Those caps allow a small team to try feature management and experimentation without a subscription, but constrain teams that need more workspaces, environments, flag treatments, or segment reach. New users can try all capabilities for 30 days before automatic downgrade to the free product, so the broader trial is temporary.

The pricing model is free, and the free edition is the plan with a stated price. No paid plan price is provided; teams that outgrow the free limits should expect custom pricing. The 30-day trial ends in an automatic downgrade, so teams should account for the free edition's caps when deciding whether it can support continued use.

Platforms

Split supports Android, iOS, web, and API. Its SDK options include JavaScript, iOS, Android, and common backend platforms, giving product teams room to connect releases across client and server applications.

Who it's for

Split is best suited to engineering and product teams coordinating gradual releases and measuring their effects on business outcomes. It is especially relevant when release monitoring and flag management belong in the same workflow. Teams needing only a simple release switch, or whose workspaces and targeting exceed the free edition's limits, should weigh whether Split's broader scope and custom-priced plans fit their needs.

Pros and cons

Pros: Feature flags, gradual-release monitoring, and experimentation analytics work together, connecting release decisions to operational signals and business outcomes.

Pros: JavaScript, iOS, Android, and backend SDK options, an Admin API, and a broad set of named integrations support varied engineering workflows.

Pros: The free edition provides a way to start without a subscription, and the trial offers all capabilities for 30 days.

Cons: The free edition permits only one workspace and two environments, limiting its usefulness for larger or more segmented deployments.

Cons: Each flag is limited to two treatments and segments to 10,000 keys on the free edition, which can restrict evaluation and targeting needs.

Cons: After 30 days, new users are automatically downgraded; teams that need more than the free caps face custom pricing.

Alternatives

For a directory of options in a different category, browse the Affiliate Link Management Software list. These products focus on affiliate link management, so Split remains the relevant choice for feature flags and release experimentation.

AffyLink, Youfiliate, Affilytics, Geniuslink, PostTap, LinkCentral, Lasso, and Pointerly are affiliate link management alternatives.

Verdict

Choose Split if your engineering and product teams need one platform to govern feature rollouts, monitor their effects, and measure business outcomes. Its joined-up workflow and broad implementation options are the main reasons to choose it; the key reasons to look elsewhere are the free edition's tight workspace, environment, treatment, and segment caps, and custom pricing once those limits no longer suffice.
