Could you build this?
No Moss is a high-performance vector search engine written in Rust and WebAssembly achieving sub-10ms latency at the edge, requiring advanced systems programming and vector index algorithmic expertise.
What it would actually take: Building this requires custom implementations of approximate nearest neighbor (ANN) search algorithms (such as HNSW, IVF-PQ, or custom graph indexes) optimized in pure Rust and compiled to WebAssembly with SIMD acceleration. It also requires an efficient cross-platform memory layout, embeddable hybrid search merging dense vectors with sparse BM25 indices, and client SDKs. This demands deep mathematical algorithm knowledge and low-level performance profiling beyond standard library wrappers.
Discussion
8 comments analyzed.
Competitors mentioned: Typical retrieval systems (200-500ms latency)
Concerns raised: Scaling performance with large content volumes (100K+ docs), Retrieval quality at scale, Performance on dense websites
Feature requests: Support for very dense/large websites, Easy integration for product sites

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
