Show HN: Nova: Open-source solution for CAD file conflicts Hey HN,

A friend at a hardware startup mentioned how their engineering team struggles with CAD file conflicts as PDM solutions are not affordable. Multiple engineers opening the same SolidWorks part = corrupted files and lost work.

I was motivated and started building Nova. Nova is a open source file locking system, designed to support multiple CAD softwares with real time locking and live dashboard to keep design engineers in sync.

Nova is built with python and Next.js.

Get started with -

  git clone https://github.com/agg111/nova
  cd nova
  pip install -r requirements.txt
  nova start
  nova --help (for more commands)
Open http://localhost:3000 in browser

I am looking for early users to get some feedback and learn about more features or bottlenecks that mechanical design teams currently face.

Show HN: Widen – Open-source Mac Postgres GUI with local or cloud text-to-SQL Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;betocmn&#x2F;widen" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;betocmn&#x2F;widen</a><p>I was paying for DataGrip for several years as my desktop database GUI but if I wanted text-to-SQL with LLMs I&#x27;d have to pay even more on top. So I decided to build my own and I&#x27;ve been using it for a few weeks now.<p>At any time I&#x27;m usually working with 3 to 6 databases, and having them set up in something like Conductor (for parallel agentic coding), but for Postgres databases, lets me quickly start a session, ask questions to my database in plain English, get a data export, move on and close the session. It&#x27;s been working well and I thought I would share it here.<p>It&#x27;s a native Mac app (Swift), free and open source (MIT). For the LLM you bring your own OpenRouter key, or there&#x27;s an experimental on-device mode using Apple&#x27;s local model, where nothing leaves your Mac. Cloud mode only sends the question and schema metadata, not your data, unless you explicitly turn that on per connection.
