Show HN: Parqeye – A CLI tool to visualize and inspect Parquet files
Show HN: Parqeye – A CLI tool to visualize and inspect Parquet files I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command.<p>Repo: <a href="https://github.com/kaushiksrini/parqeye" rel="nofollow">https://github.com/kaushiksrini/parqeye</a>

Show HN: ChartDB Cloud – Visualize and Share Database Diagrams
Show HN: ChartDB Cloud – Visualize and Share Database Diagrams Me and Guy (@guyb3) built ChartDB to generate ER diagrams from your database without a need of any database access (via query/sql/dbml). We started with an open-source version, and after seeing a lot of use we decided to make a cloud version.<p>Our OSS launch (1y ago) - <a href="https://news.ycombinator.com/item?id=41339308">https://news.ycombinator.com/item?id=41339308</a><p>Now we’re launching ChartDB Cloud - built for teams:<p>- Embed ERDs into docs, dev portals, or Miro/Notion etc.<p>- Collaborate in real-time (with live cursors like Figma)<p>- Keep diagrams always in sync with your database<p>- Organize large, messy schemas without pain<p>- Export DDL in multiple SQL dialects (solved deterministically)<p>- AI assistant to brainstorm and generate new schema objects or schema changes<p>We designed it so working with databases feels less like a chore and more like a creative process.<p>Would love feedback - especially from teams dealing with messy schemas or outdated docs.<p><a href="https://app.chartdb.io" rel="nofollow">https://app.chartdb.io</a>
