24 alternatives to A pgvector fork with the performance of Pinecone
Hi friends, Excited to share our latest project, pgvector-remote, with you all! pgvector-remote is an extension designed to effortlessly incorporate remote vector stores, like Pinecone, into pgvector. With pgvector-remote, harnessing the power of a remote (Pinecone) index becomes as easy as utilizing ivfflat or hnsw. Why pgvector-remote? 1. Simplifies integration of memory-intensive vector indexes like Pinecone into standard database servers. 2. Addresses critical feature gaps in pgvector, such as metadata filtering for AI applications. 3. Hides the complexity of maintaining and…
pgvector-remote is a PostgreSQL extension that integrates remote vector stores like Pinecone directly into pgvector. It enables developers to leverage remote vector indexes with the same simplicity as built-in pgvector… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. A pgvector fork with the performance of Pinecone launched in 2024; newer entries below may have overtaken it.

Hey, Sam and the team from ElectricSQL here. PGlite is a WASM Postgres build packaged into a TypeScript/JavaScript client library, that enables you to run Postgres in the browser, Node.js and Bun, with no need to install any other dependencies. It's 3mb Gzipped, now has support for many Postgres extensions, including pgvector, and it has a reactive "live query" API. It's also fast, with CRUD style queries executing in under 0.3 ms, and larger, multi-row select queries occurring within a fraction of a single frame. PGlite started as an experimental project we shared on X, and the…

Hey HN! Lev and Justin here, authors of PgDog (https://pgdog.dev/), a connection pooler, load balancer and database sharder for PostgreSQL. If you build apps with a lot of traffic, you know the first thing to break is the database. We are solving this with a network proxy that works without requiring application code changes or database migrations. Our post from last year: https://news.ycombinator.com/item?id=44099187 The most important update: we are in production. Sharding is used a lot, with direct-to-shard queries (one shard per query) working pretty much…

PgQueuer is a Python job queue that uses PostgreSQL for everything — queue storage, locking, notifications. No Redis, no RabbitMQ, no separate broker to operate. If your app already has Postgres, you already have the broker. After ~2 years and 26 minor releases, 1.0 ships today as the first stable release. Strict semver from here on. Thanks to everyone who contributed and left feedback!

Last summer we faced a conundrum at my company, Tiger Data, a Postgres cloud vendor whose main business is in timeseries data. We were trying to grow our business towards emerging AI-centric workloads and wanted to provide a state-of-the-art hybrid search stack in Postgres. We'd already built pgvectorscale in house with the goal of scaling semantic search beyond pgvector's main memory limitations. We just needed a scalable ranked keyword search solution too. The problem: core Postgres doesn't provide this; the leading Postgres BM25 extension, ParadeDB, is guarded behind AGPL; developing our…

Hi HN, Today we’re launching PowerSync, a Postgres<>SQLite bi-directional sync engine that enables an offline-first app architecture. It currently supports Flutter, React Native and web (JavaScript) using Wasm SQLite in the browser, with more client SDKs on the way. Conrad and I (Ralf) have been working on our sync engine since 2009, originally as part of a full-stack app platform. That version of the system is still used in production worldwide and we’ve learnt a lot from its use cases and scaling. About a year ago we started on spinning off PowerSync as a standalone product that is…

2 weeks ago, I posted chroma-exploter here: https://news.ycombinator.com/item?id=46624731 and it received a lot of positive feedback. So I decided to build a similar tool for Pinecone. While both being vector databases, Pinecone is more enterprise grade and a lot more functionally rich than Chroma, hence a separate app. This Mac native app makes it easier to work with Pinecone data, with all types of indexes (dense, sparse and hybird) and supports reranking.

We are excited to share Lantern! Lantern is a PostgreSQL vector database extension for building AI applications. Install and use our extension here: https://github.com/lanterndata/lantern We have the most complete feature set of all the PostgreSQL vector database extensions. Our database is built on top of usearch — a state of the art implementation of HNSW, the most scalable and performant algorithm for handling vector search. There’s three key metrics we track. CREATE INDEX time, SELECT throughput, and SELECT latency. We match or outperform pgvector and pg_embedding…

I have been working on Hyvector for the last five years and finally decided to present the result of my work. Hyvector is an SVG editor that runs in all modern browsers. It is stable, very fast, and capable of handling complex SVG images. Big new features like art strokes, vector tracing, colorizing are in the making, but for now the focus is on pushing a polished first release out of the door. I would love to hear any feedback on what you like, missing features, or any bugs you encounter via our issue tracker: https://github.com/hyvectorapp/hyvector-issues Note that…

Hey HN, I built Rivestack because managed PostgreSQL with pgvector is either expensive (AWS, GCP) or shared resources (Neon, Supabase free tiers). What it does: - Dedicated PostgreSQL with pgvector pre-installed - Automated backups, monitoring, HA - EU and US-East regions - Free tier for testing Benchmarks on the $29 tier: - 10k vectors: 2,000 QPS, <4ms latency - 1M vectors: 252 QPS, 32ms latency, 98% recall Stack: Hetzner infrastructure, Patroni for HA, pgBackRest for backups. Would love feedback from anyone building RAG or semantic search. Happy to answer questions!

Hey HN, we’re Robert, Din and Temirlan from Laminar (https://www.lmnr.ai), an open-source observability and analytics platform for complex LLM apps. It’s designed to be fast, reliable, and scalable. The stack is RabbitMQ for message queues, Postgres for storage, Clickhouse for analytics, Qdrant for semantic search - all powered by Rust. How is Laminar different from the swarm of other “LLM observability” platforms? On the observability part, we’re focused on handling full execution traces, not just LLM calls. We built a Rust ingestor for OpenTelemetry (Otel) spans with GenAI…
