NanoVector – A 120KB zero-dependency vector search engine in C and SIMD launched on September 11, 2026 with 10 votes, #993 of 8,093 launches that month and more than 90% of that year's launches.
In plain words
NanoVector is a lightweight vector search engine written in pure C99 that occupies approximately 120KB with no external dependencies. It performs similarity searches and episodic memory operations for AI agents, using SIMD optimizations including AVX2, FMA, ARM NEON, and x64 assembly for performance. The tool is designed for developers who need fast, efficient vector operations in resource-constrained environments or embedded systems where minimal footprint matters.

Hyvector – A fast and modern SVG editor2025 · hyvector.com · ▲331I 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…
I made a better Perplexity for developers2024 · devv.ai · ▲185Hi HN, I am Jiayuan, and I'm here to introduce a tool we've been building over the past few months: Devv (https://devv.ai). In simple terms, it is an AI-powered search engine specifically designed for developers. Now, you might ask, with so many AI search engines already available—Perplexity, You.com, Phind, and several open-source projects—why do we need another one? We all know that Generative Search Engines are built on RAG (Retrieval-Augmented Generation)[1] combined with Large Language Models (LLMs). Most of the products mentioned above use indexes from general search engines…
