Platform
Everything research teams actually need
Qlarr combines the tools that usually require five separate subscriptions into one open-source platform your team controls.
Collect everywhere
Capture responses online, offline, or in low-connectivity environments. Run the same survey across devices, panels, and field teams, with data syncing automatically once connectivity is restored.
Validate as you go
Apply validation rules at the point of entry or let Qlarr AI handle the configuration for you. Capture GPS, timestamps, and background audio to verify responses and catch quality issues before they reach your analysis.
Own your infrastructure
Deploy Qlarr on your own infrastructure in a single command with a fully open-source codebase, or use Qlarr's managed cloud and skip the DevOps. No vendor lock-in. Full data sovereignty. Your choice.
Qlarr AI
AI that understands research and handles the work
Qlarr's AI agents work within your project. They understand your objectives, ask the right questions, and execute complex tasks across your research workflow.

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, or describe what you need and let Qlarr AI handle the configuration. Either way, no developer required.
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
Qlarr combines built-in validation with quality controls like GPS coordinates, timestamps, and background audio. Use Qlarr AI to configure validation rules that catch inconsistencies early. Clean data starts at collection, not post-processing.
Open source with a cloud option
Run Qlarr on your own infrastructure for full control, or choose our managed cloud to get Qlarr AI and skip the DevOps. No vendor lock-in. Your infrastructure, your choice.
