Harness Feature Flags vs Split

SaaS & On-Premises Support:

Split only offers a SaaS version of their product. Harness supports both SaaS and on-prem deployment models.

Primary Users:

Delivering software is a process that starts at building an application. In the same way, feature flags should provide value to teams at each phase of the software delivery lifecycle. It’s not just about shipping code faster and creating improvements for users; feature flags should also make daily operations easier, and provide visibility and management ability. Harness Feature Flags was built to support all of these use cases across Developers, Product Managers, Operations, and Engineering Managers. 

The focus is unleashing the power of feature flags for software delivery teams holistically. And while Harness focuses on a developer-first experience, the same workflows and processes are built to support software delivery teams where they struggle the most. Hint: it’s not just shipping features.

Simple Developer Onboarding:

When building Feature Flags, Harness focused heavily on the developer experience - developers are, after all, the true arbiters of feature flags. Our intent was to make sure that the setup process is fast and intuitive, and that teams can get started and see value from feature flags right away. As of today, we don’t see this sort of first-class support for developers coming from Split. In fact, with their primary focus being on marketing and product teams for experimentation, we’re not confident that they ever will create this support. 

Feature Flag Pipelines:

Harness features a visual drag-and-drop pipeline builder that supports hundreds of integrations, and this is a standard part of the Harness platform. Users unlock automated progressive delivery, and Harness uniquely allows for automated feature verification so that users don’t have to monitor stages of their rollout and can truly automate rollout and kill switches.

Native CI/CD Support & Pipeline Extensibility:

Split, as a third-party tool, is completely abstracted from your CI/CD process, which perpetuates the view that feature flags are an ancillary step. Ideally, this view would be abolished. At Harness, we view feature flags as a crucial part of the CI/CD pipeline - and as such, it becomes a natural step in the everyday workflow of development teams and is integrated into CI/CD as a unified pipeline. This allows for users to get visibility into any change from code to release, and create standardized and automated processes across all stages of the SDLC.

As part of the Harness platform, users also can rest easy knowing that they can get a full audit log, manage teams with security like RBAC, share environments and APIs, and see cross-platform analytics. Of course, all of this is available for just Harness Feature Flags, and its power is more pronounced on the platform.

Config-as-Code & GitOps:

Split’s user focus is on marketing and product teams for experimentation. However, it’s typically the developer teams who are the arbiters of feature flags, with experimentation being a resulting capability. At Harness, we chose to focus on the development point of the value chain. 

It’s important to meet developers where they are and work within their processes. With Harness, teams have the ability to create pipelines visually and combine that with a pipelines-as-code or config-as-code approach; visual pipelines create YAML files that can be changed to reflect back into the visual pipeline, and these can automatically be synced with Git so changes are reflected immediately and without added effort, all from within our platform.

SDK Support:

Harness and Split support all major languages, both server-side and client-side (except for Split not supporting Golang). However, it would be unjust not to mention that Split, as of today, supports a few more SDKs. Harness Feature Flags has been on the market since July 2021 and supports a total of 10 SDKs. Split supports 14, and it’s only a matter of time until Harness far outpaces the rate of SDK support from Split because of our developer-first focus.

Automated Feature Verifications:

Harness initially pioneered the concept of Continuous Verification in the software delivery space. Having battle-tested the capability over years with hundreds of customers, the ability to have Harness automatically monitor deployments and take appropriate rollout or rollback options is extended into Harness Feature Flags. Users can use the ML-based automated verification feature to have Harness automatically verify the health of live features and take appropriate remediation action should things go wrong - it obviates the need for users to manually monitor and make changes during a feature rollout.

While Split does provide feature verification, as of today it seems limited in its support and level of automation. Notably, it seems to have a pretty shallow integration library, and it focuses more on alerting of issues rather than allowing users to preconfigure desired actions based on verification outcomes.

Security/Access Control:

The key difference between Harness and Split is the extensibility of security and access control to more than just feature flags. With the native Harness support for CI/CD, users can extend the same security/access control profiles end-to-end across SDLC, rather than having to learn multiple tools and create those controls from scratch. By simplifying this process end-to-end, users are able to focus on using the tools rather than configuring them.

At Harness, we take security extremely seriously, as evidenced by our DevSecOps approach. We took the same views with Feature Flags, ensuring RBAC and SSO were available from inception, with more controls coming soon. 

Governance & Compliance:

Harness takes governance and compliance seriously, providing CI/CD users with fine-grained RBAC, audit trails, many ways to manage secrets, and more. We’ve taken that same approach with Feature Flags and are investing heavily in the area, letting teams build rules and processes, and helping automate cleanup and flag management. Harness also supports Open Policy Agent (OPA), enabling Enterprise-scale governance as-code across Feature Flags and the rest of the Harness platform. Harness is the only feature management solution to offer this.

Reporting & Dashboards:

Since Split is a standalone feature flags tool, reporting and dashboards are limited to data within the tool itself - understandably so. Harness, however, is in the process of linking Feature Flags data to the rest of the software development lifecycle, and as such, will provide reporting and dashboards for all products in the same easily-accessible place. Harness is actually the only platform on the market that brings together analytics across the whole SDLC into one place - one tool to rule them all, one tool to bind them.

But what if you’re using only feature flags and don’t care about CI/CD? Harness provides the most complete visibility into feature flags of any tool on the market. Any bit of data that’s related to your feature flags use and operation, you can visualize in Harness to create custom dashboards to show exactly what you need at any time.
