Heimdall

What it does

  Hey HN, We built Heimdall (heimdallspace.com) because the existing tools for space situational awareness are genuinely painful to use: clunky interfaces, fragmented data sources, slow rendering. The ones that aren't are locked behind enterprise solutions. We thought the foundation of this should be open and accessible. The goal is a satellite observability platform: one place that gives operators complete, real-time insight into their assets and the orbital environment around them. Today's release is the foundation—aggregating and rendering the full public space catalog (30,000+ objects) in…

  Hi HN, I'm Tim, solo founder of Spanly (https://spanly.com). I spent the last year working on MCP gateways, and debugging them with nothing better than HTTP-level APM was painful. Spanly runs its own MCP server and monitors it with itself, so I've been the first user of everything below. Spanly is observability for MCP servers, the protocol that lets agents like Claude and Cursor call your product's tools. It's a sidecar proxy, so it works with any language and requires zero code changes. Live demo (no signup): https://app.spanly.com/share/demo Sidecar source…

  I spent 3 years reverse-engineering a 40 yo stock market sim from 1986▲721

  Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
