• •Varad Agarwal released Forge, an open-source JavaScript runtime built on Mozilla’s SpiderMonkey engine.
• •The project positions itself as an alternative to V8-based runtimes like Node.js or Bun.
• •It remains unclear how Forge handles complex Node.js compatibility layers, as the project is in its early stages.

Developer Varad Agarwal has released Forge, a new JavaScript runtime leveraging the SpiderMonkey engine rather than the more common V8. While V8 dominates the ecosystem due to Chrome and Node.js, using SpiderMonkey—the engine behind Firefox—is a niche architectural choice with distinct performance and memory characteristics. However, the runtime currently lacks established support for standard Node.js APIs, creating a high barrier to entry for production applications. The project's long-term utility will depend on its ability to bridge the gap between SpiderMonkey's unique capabilities and the existing JavaScript developer ecosystem.
