Products that do what Minikv – Distributed key-value and object store in Rust (Raft, S3 API) does
Hi HN, I’m releasing minikv, a distributed key-value and object store in Rust. What is minikv? minikv is an open-source, distributed storage engine built for learning, experimentation, and self-hosted setups. It combines a strongly-consistent key-value database (Raft), S3-compatible object storage, and basic multi-tenancy. I started minikv as a learning project about distributed systems, and it grew into something production-ready and fun to extend. Features/highlights: - Raft consensus with automatic failover and sharding - S3-compatible HTTP API (plus REST/gRPC APIs) - Pluggable…

PicoMQ is a Rust server for Durable Streams, built on Object Store. Cheap, URL-addressable, granular streams (create/append/read/long-poll/SSE), with Pico Protocol or Durable Streams Protocol as the facade. S3Stream is the stream storage primitive, used in AutoMQ, shipped as a Rust library. Coordination is a command log in Postgres.

Hey HN! I work on a database for my day-job and I realized I had never written one from scratch, so I wrote bugfruit! Once I was mostly satisfied with it, I looked up some benchmarks to compare my simple database to other brand name key-value stores. I was surprised to see that mine held up fairly well on the subset of benchmarks I replicated. So I used the Pavlo Database Naming System [0] to name it and open-sourced the code. I'd love to hear any feedback you might have on it! [0] https://www.cs.cmu.edu/~pavlo/blog/2020/03/on-naming-a-datab...

Hi HN, I built KeyEnv because I was tired of the "can you Slack me the Stripe key?" workflow. The problem: My team's secrets lived in a mix of Slack DMs, shared Google Docs, and .env files that definitely weren't in .gitignore at some point. Enterprise tools like Vault required more DevOps time than we had. Doppler was close but felt heavier than we needed. What KeyEnv does: keyenv init # link project keyenv pull # sync secrets to local .env keyenv run -- npm start # inject secrets, run command That's basically it. Secrets are encrypted client-side (AES-256-GCM) before leaving your machine.…

Hi HN! I've been building a project that handles high-value credentials in-process, and I wanted something more robust than just zeroing memory on drop. A comment on a recent Show HN[0] made me realize that awareness of lower-level memory protection techniques might not be as widespread as I thought. The idea here is to pull out all the tools in one crate, with a relatively simple API. * mlock/VirtualLock to prevent sensitive memory from being swapped (eg the KeePass dump) * Core dump exclusion using MADV_DONTDUMP on Linux & Android * mprotect to minimize exposure over time * Guard…

I built *snkvDB* — a single-header, ACID-compliant key-value store with zero setup. https://github.com/hash-anu/snkv ### Why I built this I wanted something as simple as a hashmap, but: * persistent * crash-safe * no external dependencies * easy to drop into any C/C++ project Most KV stores are either: * too heavy (servers, background processes), or * too low-level (you manage everything) snkvDB tries to sit in between. --- ### What it is * Single-header KV store (just include and use) * ACID compliant (thanks to SQLite) * No server, no config, no build system…

There are many commercial YouTube summarizers, but I couldn't find an open-source one that truly fit my needs. So, I built YouTubeTLDR: a simple, self-hostable solution that uses the Gemini API without much bloat. I went with a synchronous approach + threading which was a nice break from Tokio. It is Bring Your Own Key, but the key is sent to the server for each request, which is something I might revise in the future. There is a demo on https://youtubetldr.onrender.com/

Hi HN, I built EdgeVec, a vector database that runs entirely in the browser. It implements HNSW (Hierarchical Navigable Small World) graphs for approximate nearest neighbor search. Performance: - Sub-millisecond search at 100k vectors (768 dimensions, k=10) - 148 KB gzipped bundle - 3.6x memory reduction with scalar quantization Use cases: browser extensions with semantic search, local-first apps, privacy-preserving RAG. Technical: Written in Rust, compiled to WASM. Uses AVX2 SIMD on native, simd128 on WASM. IndexedDB for browser persistence. npm:…
