That statement would have been controversial in 2022, when the default answer was &ldquo;stand up a vector database service and point your app at it.&rdquo; In 2026 the embedded tier is genuinely good — and it is the right answer for a surprising number of projects. The three options that matter are <strong>pgvector</strong> (23,326 stars), <strong>LanceDB</strong> (11,652 stars), and <strong>sqlite-vec</strong> (8,183 stars). One bolts onto the database you already run, one is a columnar library that lives inside your process, and one is a single C extension that runs anywhere SQLite compiles. Picking the wrong one means either a migration later or paying operational costs for capacity you never needed.</p>
