WASM SIMD vector DB in browser beats JavaScript 5x, but limited to in-memory search.

Strengths
  • WASM SIMD acceleration genuinely outperforms JavaScript—measurable 5x speedup with benchmarks
  • Clever use of OPFS for client-side persistence eliminates server dependency entirely
  • Clean demo UI with realistic character-frequency embedder, not toy data
Weaknesses
  • Browser-only scope severely limits use cases vs. production vector databases (Pinecone, Weaviate)
  • Undefined scalability: unclear how performance degrades beyond demo dataset sizes
Target Audience

Web developers, ML engineers building browser-based search applications
