Apache ECharts with 29 chart types, a Perspective datagrid with pivot and WebGL charts, and the pivotkit report builder, each one a module of its own.

Tools I wanted to exist, built so others can use them too.
I'm René. I build open-source tools for reports, Home Assistant, Synology and PowerShell: typed, read-only where it matters, documented end to end and tested on real hardware.

pivotkit
Excel's PivotTable for web apps and the command line. People load their data, build the report by dragging fields and take it to Excel. The same report renders again in CI, behind a REST service or for an AI client.
- Bring your own file. CSV, JSON or Excel dropped onto the report, with a preview and a type per column. Nothing is uploaded.
- Excel with the layout kept, plus the rows behind every number as CSV or JSON.
- Views are safe JSON with a published schema. A view cannot run code, and the CLI checks it in CI.
- One report, many places: React, a web component, Node, a command line, a REST service with a container image, and an MCP server that never hands the model the rows.

Synology packages
Packages for Synology NAS and routers that install like any other and start again after a reboot.

PSItems
find, grep and du the PowerShell way: a fast, cross-platform module for files, folders, content and sizes.
