The short version

  • Each has a real cost: Split split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.; Tricentis Tosca licensing is quoted per workstation at enterprise figures, so the tool only pays back where testing headcount is already large; a team of five will not recover the cost.
  • They diverge on capability: Split covers Feature flags with targeting, Tricentis Tosca covers Model based test design.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Split

  • Split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
  • Harness no longer publishes per-module prices, so an organisation that wants only feature management cannot get a list price and must negotiate a module out of a platform bundle.
  • The measurement engine needs traffic volume to reach significance, so a product with modest usage gets flags with an experimentation layer it will rarely be able to conclude anything from.
  • Metric attribution depends on correctly instrumented events flowing into Split, which is an integration project in its own right; without it you have paid for an experimentation platform and are using it as a flag switch.
  • As part of a larger DevOps suite the roadmap now competes with CI, CD, security and cloud cost modules for attention, so feature management is no longer the company’s single focus the way it was as an independent product.

Tricentis Tosca

  • Licensing is quoted per workstation at enterprise figures, so the tool only pays back where testing headcount is already large; a team of five will not recover the cost.
  • Building the initial application model takes months and is usually done with paid consultants, meaning value arrives long after the invoice does.
  • The authoring environment is Windows only and heavy, which sits awkwardly in organisations whose engineers work on macOS or Linux.
  • Tricentis has assembled its portfolio through acquisitions, so products sold together vary in how deeply they are integrated and a buyer should verify the joins rather than the diagram.
  • Skills are specific to Tosca and not transferable, so recruiting testers means hiring for a niche tool and losing a trained one hurts more than losing a Selenium engineer.

Answered from the vendors’ own pages

Split: Is Split still called Split?

It is now sold as Harness Feature Management and Experimentation after the Harness acquisition, and split.io redirects to harness.io.

Tricentis Tosca: Is Tosca scriptless?

Test assembly is scriptless, but non trivial estates still need TQL queries and custom modules, which is programming under another name.

Split: Can I buy just feature flags?

Not from a price list. Harness publishes bundle tiers and directs single-module buyers to sales.

Tricentis Tosca: Why does it dominate SAP testing?

It holds SAP certification, covers SAP GUI and Fiori at transaction level, and is sold through the same integrators that run SAP programmes.

Split: What does it do that a plain flag service does not?

It attributes changes in your product metrics to specific flags with statistical significance testing and alerts on guardrail metrics.

Tricentis Tosca: Can it replace Selenium for a web only product?

It can, but the economics do not work. Model based testing pays off across large heterogeneous estates, not one web application.

Split: Do we need a lot of traffic?

Yes. Statistical tests need volume to conclude, so low-traffic products get limited value from the measurement layer.
