Forge brings SpiderMonkey to a new JS runtime built by a solo dev

Forge is a JavaScript runtime that uses Mozilla's SpiderMonkey engine — the same one powering Firefox — rather than V8, which underpins Node and Deno. For indie developers, an alternative runtime built around a different JS engine opens questions about performance characteristics and embedding possibilities that the V8 monoculture doesn't address. It's early-stage work from a solo maker, but the engine choice alone makes it worth watching.
