Forge is an experimental JavaScript runtime built on Mozilla's SpiderMonkey engine.
The project focuses on building a modern JavaScript runtime from the ground up with a native, high-performance architecture instead of layering new APIs over existing runtimes.
- ✅ Windows x64
Linux and macOS support are planned.
