The short version
- Each has a real cost: Eppo datadog acquired Eppo in May 2025 and is folding it into Datadog Experiments, so you are now buying a component of an observability suite rather than an independent product, and roadmap priorities will follow Datadog’s bundle strategy.; 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: Eppo covers Warehouse-native analysis, Tricentis Tosca covers Model based test design.
- Prices and features above were last checked on 31 August 2026.

The jobs each tool is most often brought in to do.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Eppo
- Datadog acquired Eppo in May 2025 and is folding it into Datadog Experiments, so you are now buying a component of an observability suite rather than an independent product, and roadmap priorities will follow Datadog’s bundle strategy.
- No pricing is published anywhere, before or after the acquisition; the site offers only a demo request, so cost cannot be estimated without a sales process and is likely to be quoted alongside a wider Datadog contract.
- Because analysis runs in your warehouse, Eppo shifts compute cost onto your Snowflake or BigQuery bill; a large experiment programme with frequent recomputation raises a line item that does not appear in the Eppo quote at all.
- Results are only as fresh as the pipeline feeding the warehouse, so teams used to near-real-time dashboards from an event-based tool will wait hours for updated numbers, which slows down the fast iteration loops some product teams rely on.
- It assumes a mature data stack with a warehouse, defined metrics and analysts who can maintain them; an organisation without that has to build the data foundation first, which makes the real adoption cost far larger than the licence.
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
Eppo: Is Eppo still a separate product?
It is still sold and supported, but Datadog acquired it in May 2025 and it is branded as Datadog Experiments. Buy it expecting a Datadog product roadmap.
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.
Eppo: What does it cost?
Nothing is published. There is no pricing page, only a demo request, and pricing is now likely bundled into a Datadog agreement.
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.
Eppo: Does it need a data warehouse?
Yes. Warehouse-native analysis is the whole architecture. Without Snowflake, BigQuery, Redshift or Databricks there is no product.
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.
Eppo: Does it include feature flags?
Yes. Assignment and measurement come from the same system, which is the main reason teams pick it over pairing a flag tool with a separate analysis tool.
