pgvector on Postgres you already run: prove you picked the right distance operator
Use pgvector in the Postgres you already run instead of standing up a dedicated vector database, and prove the distance operator you query with (<-> L2, <=> cosine, or <#> inner product) matches your embeddings, so your semantic search doesn't silently rank the wrong rows first.
zvec: run vector search inside your app, no server, offline
Embed a vector database directly into your process with zvec, insert vectors, and query for nearest neighbors, with no separate server to run, config, or babysit.
LlamaIndex: index your documents and query them at runtime
Point LlamaIndex at a document corpus and build a VectorStoreIndex so an agent can retrieve the relevant chunks at query time instead of stuffing everything into context.
Crawl4AI: a page to clean, LLM-ready markdown (no API key)
Write a Crawl4AI run script that turns a page into clean markdown with a cache mode set, and verify the script is valid and shaped right before you point it at a site.
