The short version

  • Each has a real cost: Alchemer more expensive than the simple form builders, which is the fair comparison for a short survey; Sigma Computing every user interaction is a live warehouse query, so compute costs rise with adoption and land on the warehouse invoice rather than the BI line item, which routinely surprises the team that approved the purchase.
  • They diverge on capability: Alchemer covers Deep question logic, Sigma Computing covers Spreadsheet interface over SQL.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Alchemer

  • More expensive than the simple form builders, which is the fair comparison for a short survey
  • The interface carries a long product history and is less immediately friendly than newer tools
  • Advanced logic is powerful and correspondingly easy to misconfigure, and testing a complex survey is real work
  • Named Alchemer since 2020, so much of the searchable material still says SurveyGizmo

Sigma Computing

  • Every user interaction is a live warehouse query, so compute costs rise with adoption and land on the warehouse invoice rather than the BI line item, which routinely surprises the team that approved the purchase.
  • It cannot work without a supported cloud data warehouse, so an organisation running analytics on an on-premises database or a plain application database has nothing to connect to.
  • Pricing is not published and seats are differentiated by capability, so budgeting requires a sales cycle and a headcount forecast before you can compare it with a tool you could simply buy.
  • Performance is only as good as the warehouse behind it, which means slow or badly modelled tables surface as a slow interface and the fix is a data engineering project, not a Sigma setting.
  • Statistical and scientific visualisation is limited compared with dedicated tools, so anything beyond standard business charting has to be done elsewhere and brought back in.

Answered from the vendors’ own pages

Alchemer: What does Alchemer cost?

Tiered annual subscriptions published on the vendor site. Check current rates there.

Sigma Computing: Does Sigma store a copy of my data?

No. Queries are executed on your warehouse and results are returned for display, which is why there is no extract refresh to manage.

Alchemer: Is Alchemer the same as SurveyGizmo?

Yes. SurveyGizmo was renamed Alchemer in 2020, which is why older reviews and documentation use the former name.

Sigma Computing: What does it actually cost?

The vendor does not publish prices. Expect an annual contract priced by seat type, plus a warehouse compute increase you should model separately.

Alchemer: When is it worth more than a simple form builder?

When the questionnaire has real conditional logic, or when responses need to route into Salesforce or a data warehouse.

Sigma Computing: Can business users break the warehouse?

They can run expensive queries. Warehouse sizing, query limits and materialised tables are the controls, and they need configuring before a wide rollout.

Sigma Computing: Is it a replacement for a modelling layer like dbt?

No. Sigma works best on top of modelled tables and is usually deployed alongside dbt rather than instead of it.
