Movement

This is the first edition on this tier, so no move can be computed for Split yet. From the next edition this section shows, per buyer segment, whether its share moved by more than the measured noise floor.

By model

How each model treated Split across every prompt where it was named for a mid-market B2B company. Twelve models, six prompts per category.

What the models said for it

Verbatim evidence the judge attached to positive labels.

“Split: A feature management tool that offers managed feature delivery with audience rules and rollout measurement built into one system.” Llama 4 Maverick · Feature flags · paraphrase prompt · alternative
“Enterprise with serious governance/compliance needs → LaunchDarkly, or Split/Harness if experimentation in CI/CD matters.” DeepSeek V4 Flash · Feature flags · comparative prompt · alternative
“Another solid B2B option with strong experimentation features and enterprise-grade governance” MiniMax M2.5 · Feature flags · paraphrase prompt · alternative
“Choose Split if: Experimentation and statistical rigor are core to your product” Kimi K2 · Feature flags · paraphrase prompt · alternative

And against it

Verbatim evidence attached to negative labels. A warning on a product with few labels is a warning; on a product with many, it is one voice among them.

“Avoid for tight budgets: LaunchDarkly/Split (free tiers cap quickly, then $10+/MAU or seats).” Grok 4.1 Fast · Feature flags · budget prompt · hard negative
“its pricing model is also complex and can be costly for smaller teams. Some users report a steep learning curve” Mistral Small · Feature flags · negative prompt · soft negative
“Split (acquired by Harness) — flags + A/B testing, but product direction has been mixed since acquisition.” DeepSeek V4 Flash · Feature flags · scale prompt · soft negative
“Split.io (now Harness-integrated): Opaque pricing, rapid scaling bills, weaker CI/CD vs. peers.” Grok 4.1 Fast · Feature flags · negative prompt · soft negative

What carried it into the answer

The sites and pages cited by the answers that named Split. A fact about retrieval, not a lever on the model.

Citations exist only for the models that return a source list, four of the twelve in this edition, so these counts come from 67 of the 81 answers that named Split and are not a share of its labels.

Claim this page

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Split's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Split, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.

It does not get any change to labels, shares or verdicts, any preview, or any say over which quotes appear. A verification link goes to your work email; an address at splitmetrics.com is approved on the spot, any other address is reviewed by hand.

Your name and company appear on the claimed page, or the company alone if you ask below. A title and a LinkedIn address appear there too if you give them, and are left off if you do not. Your email address is never published.
