Boards and nodes
One board per process. Each node is a SQL query with a name, color and icon. No YAML, no config files.
Local · Serverless · DuckDB
Your data on autopilot.
A local visual data orchestrator built on DuckDB. Draw each process as a map of SQL nodes, schedule it and let it run on its own. All from your desktop.
Boards
Understand the process at a glance.
A board is a control panel per process: sales, inventory, reports. Each node reads like a card, not like code, and arrows document how they relate. Each node runs on its own schedule.
- Scheduled or manual nodes
- Run any node with one click
- Full-screen presentation mode
Scheduling
Schedule without writing cron.
Pick every X minutes, daily, weekly or monthly with a visual builder. Already fluent in cron syntax? Advanced mode accepts expressions in that same format. And each node decides who to notify and when.
- Email alerts through your own SMTP
- Native system notifications
- Always, only on failure or only on success
Everything a data process needs.
No servers to maintain, no services to pay for.
