{"id":73587,"title":"Epsilla - A 10x faster open source vector database","tagline":"The information retrieval foundation for the next generation of AI applications","body":"### **🚀 TL;DR**\n\nEpsilla is an open-source vector database. Epsilla offers low-latency searches across billions of vectors, consumption-based database-as-a-service, comprehensive APIs, and multi-language bindings. Our team has 7 years of experience building the high-performance graph database, and our advanced ANN index leverages parallel graph traversal technology, making the vector search 10x faster.\n\n![uploaded image](/media/?type=post\u0026id=73587\u0026key=user_uploads/14642/801e5229-0b56-4eb5-a3fb-e5ff7d2686ec)\n\n### **❌ The Problem**\n\nWith the surge of LLMs and the evolution of AI agents for task planning and decomposition for complex tasks, a **high-performance vector database** for information retrieval and enhancing context in prompts is a **MUST**! Most vector databases utilize HNSW, and its performance significantly degrades when aiming for high search precision.\n\n### **⭐️ Our Solution**\n\nWe’ve reimagined vector search from the ground up for scalability, performance, and cost-effectiveness. We implemented the state-of-art ANN index algorithm from the academia that leverages intra-query parallel graph traversal, which outperforms HNSW by **5x** on high precision query latency on medium size (1M) vector space and outperforms HNSW by **50 times** on large-scale vector search.\n\n![uploaded image](/media/?type=post\u0026id=73587\u0026key=user_uploads/14642/7f276b64-0500-4286-b589-e23d339abe6d)\n\n### **🔦 The Ask**\n\n* Try us at \u003chttps://epsilla-inc.gitbook.io/epsilladb/quick-start\u003e\n* Follow our repo at \u003chttps://github.com/epsilla-cloud/vectordb\u003e\n* Connect with us on [Discord](https://discord.gg/cDaY2CxZc5)\n* Let’s talk at \u003chttps://epsilla-ai.larksuite.com/scheduler/a80f6a3202d4c328\u003e!","slug":"J8t-epsilla-a-10x-faster-open-source-vector-database","created_at":"2023-07-31T01:45:04.471Z","updated_at":"2026-05-25T05:22:56.964Z","total_vote_count":41,"url":"https://www.ycombinator.com/launches/J8t-epsilla-a-10x-faster-open-source-vector-database","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":28900,"name":"Epsilla","slug":"epsilla","url":"https://www.epsilla.com/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/a2a1e40bf12e61df1ea8d4d6a4f8b7691ac3982f.png","batch":"Summer 2023","industry":"B2B","tags":["SaaS","Infrastructure","AI","Databases"],"search_path":"https://bookface.ycombinator.com/company/28900"}}
