Platform

Everything research teams actually need

Qlarr combines the tools that usually require five separate subscriptions into one open-source platform your team controls.

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.

Collect everywhere

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.

Validate as you go

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.

Own your infrastructure

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.

Why Qlarr

Power without the usual pain

Research tools tend to make you choose: sophisticated features, or ease of use. Qlarr doesn't ask you to choose.

$0

to get started

Free self-hosted tier and a free cloud plan. No card required

No survey programmer needed

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.

Offline-first by design

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.

Data quality built in

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.

Open source with a cloud option

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.
