Design surveys in minutes
Build complex logic-driven questionnaires in a no-code editor, or brief Qlarr AI to generate your survey from scratch. Move from research idea to live deployment without developer queues.
An open-source platform built to remove friction from research workflows. Design, collect, validate, and own your data — without the usual pain.
Free to self-host · GDPR-compliant cloud · No credit card required
Qlarr combines the tools that usually require five separate subscriptions into one open-source platform your team controls.
Build complex logic-driven questionnaires in a no-code editor, or brief Qlarr AI to generate your survey from scratch. Move from research idea to live deployment without developer queues.
Capture responses online, offline, or in low-connectivity environments. Run the same survey across devices, panels, and field teams — data syncs automatically when connection restores.
Apply GPS capture, timestamps, background audio recording, and response-quality signals at the point of data entry. Detect fraud and fix quality issues before they reach your analysis.
Self-host on your own servers with a fully open-source codebase. No vendor lock-in. Full data sovereignty. Deploy in five minutes with a single command.
Whether you're running market research, field data collection, or academic studies — Qlarr is designed around how research actually works.
Research tools tend to make you choose: sophisticated features, or ease of use. Qlarr doesn't ask you to choose.

to get started
Free self-hosted tier and a free cloud plan. No card required
Qlarr's no-code editor handles complex branching, skip logic, piping, and quota controls — the kind of logic that usually requires a developer or specialist tool.
Not an afterthought. Offline data collection is baked into the core architecture, not a plugin. Responses sync reliably when connection returns, with no data loss.
GPS coordinates, response timestamps, background audio triggers, and fraud-detection signals are available at the question level. Clean data starts at collection, not post-processing.
Run Qlarr on your own infrastructure for full control, or use our GDPR-compliant cloud and skip the DevOps. Same codebase, same features, your choice.
Join teams using Qlarr to design, collect, and validate research data without the usual friction. Free to start, open to inspect.
