Surprised this hasn't been shared here before.

Built by my former colleague, Stewart Allen (Co-Founder/CTO of WebMethods, CTO of AddThis, Co-Founder/CPO of IonQ, et al.).

What caught my attention:

- 100% free, no subscriptions, no accounts, no cloud

- Local-first: all slicing and toolpath generation runs on your machine

- Works in any browser, even offline once loaded

- Supports FDM/SLA, CNC milling, laser cutting, wire EDM

- Fully open source: github.com/GridSpace/grid-apps

Refreshing to see a tool that isn't trying to lock you into a subscription or harvest your data.
