Show HN: ParqDB – No query server. Vector search in the browser
ParqDB is a vector search tool that runs entirely in the browser, requiring no backend query server.
ParqDB launched on August 19, 2026, as a vector search tool that operates entirely within the browser, with no query server required, according to a Show HN post by author petrizhang.
The project, accessible at search.parqdb.io, positions itself around the idea of removing the backend infrastructure typically needed to run vector search — meaning queries are executed client-side rather than routed through a dedicated server. The Show HN submission offers no further detail on pricing, team size, or funding.
The source provides minimal background on the company or its founders. The HN post was authored by petrizhang and had received 2 points and no comments at the time of posting.
Client-side vector search is a small but active area of development, as WebAssembly and browser-native compute have made it more feasible to run embedding and similarity-search workloads without a round-trip to a server. ParqDB appears to be targeting developers who want to embed search functionality into web applications without standing up or paying for dedicated vector database infrastructure.
No roadmap, pricing model, or expansion plans were mentioned in the HN submission. Further technical details would need to be drawn from the product itself at search.parqdb.io.
