I worked 9 months on Wasmi 2.0 and ~1.5 months on just this article and the preparation that went into it.
The article goes quite deep into technical details about fast interpreter design and I hope someone here enjoys reading it as much as it did working on it.
Happy to answer questions.
Note: article is fully hand-written since I hate reading generic AI written articles myself.
I have bookmarked a few projects in this category over the years, but never really ran into the need for it. Would love some real-world examples. I envision that in the agentic age there are more than ever.
Ripple: deterministic execution and metered gas matter more there than raw speed
Game Engines:
Firefly Zero: an awesome handheld console whose cartridges are Wasm modules
Embedded/IoT and Cloud Hosts
Sometimes a JIT is not allowed or no option. Some platforms forbid JIT entirely, e.g. iOS or some hardened cloud sandboxes.
Also recently someone approached me about using Wasm runtimes (e.g. Wasmi) for LLM-generated throw-away code. Considering Wasmi's outstanding startup times, this might also be a great fit.
