An independent studio for Power BI tooling and data‑driven research.
Run by Igor Cotruta from London, UK. We build small, focused tools for developers, data engineers, and IP professionals — and publish what we learn along the way.
powerquery.io. An always‑current reference for the Power Query M language — auto‑generated from Power BI Desktop’s #shared structure, with search, dark mode, and multi‑language support.
PBIXray. An open‑source Python library and macOS app for inspecting .pbix files — tables, columns, DAX, M queries, relationships, and RLS — without Power BI Desktop.
pbix.info. A browser‑based Power BI file inspector. Drop a .pbix in and explore its internals — no install, no upload.
Trademark.fyi. Market intelligence on Madrid System trademark refusals — turning the daily WIPO Gazette into actionable insights on active offices, firms, and representatives.
Powernote. A Cloudflare Worker reverse proxy for Power BI’s publish‑to‑web reports — serves them under your own custom domain and strips the default bottom bar.
