Blaise review
A multimode survey platform for complex studies, with offline mobile collection and case management.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Blaise is commercial survey software from Statistics Netherlands for government, scientific, personal, household, and economic surveys. It is designed for organisations running complex or large-scale studies across web, telephone, face-to-face, and mobile collection modes. Questionnaire programming includes survey-flow logic and selective checking, while responsive instrument design supports different devices and screen sizes. Native Windows, iOS, and Android applications extend collection beyond the browser.
The strongest fit is multimode interviewing where field teams need continuity across connected and disconnected settings. Blaise supports offline data collection with later synchronization, case management for interviewer workloads and assignments, and data validation during collection. Its combination of routing, hierarchical and relational data structures, and survey data processing is suited to studies that require more control than a basic form builder. Organisations focused on mobile or interviewer-led work should find these capabilities especially relevant.
Blaise uses a contact-sales pricing model and is licensed commercial software. The platform includes APIs and integration support, with web, Windows, iOS, Android, and API access across its delivery options. That breadth supports teams coordinating several collection channels, but organisations seeking a simple self-serve survey product may prefer a narrower tool with a more direct purchase path. Blaise is the stronger choice for structured, multimode programs with offline requirements; it is less suitable for small teams that only need straightforward online questionnaires and minimal operational management.
