Tinykv – Minimal file-backed key-value store for Rust▲24
I built tinykv because I kept reaching for simple persistent storage in Rust projects but found existing solutions either too complex (sled) or unmaintained (pickledb). tinykv focuses on simplicity: JSON-based, serde-powered, with optional TTL. Perfect for CLI tools, game saves, config storage. Would appreciate any feedback from the HN community!

Minikv – Distributed key-value and object store in Rust (Raft, S3 API)▲71
Hi HN, I'm Emilie, I have a literature background (which explains the well-written documentation!) and I've been learning Rust and distributed systems by building minikv over the past few months. It recently got featured in Programmez! magazine: https://www.programmez.com/actualites/minikv-un-key-value-st... 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. Features/highlights: - Raft…

A bi-directional, persisted KV store that is faster than Redis▲79
we've been working on a KV store for the past year or so which is 2-6x faster than Redis (benchmark link below) yet disk persisted! so you get the speed of in-memory KV stores but with disk persistence. To achieve this we've created our custom filesystem that is optimized for our special usecase and we're doing smart batching for writes and predictive fetching for reads. In addition to basic operations, it also provides atomic inc/dec, atomic json patch, range scans and a unique key monitoring mechanism (pub-sub) over WebSockets which essentially allows you to receive notification on…

Kiwi – End-to-End Kafka Subscriptions with WebAssembly▲14
Hey HN! I'm excited to announce the release of Kiwi v0.1.1. I started working on Kiwi a few months ago with the primary motivation of providing an extensible WebSocket adapter that allows client applications to securely subscribe to real-time data sources such as Kafka. Often times, there is a desire to extend the real-time data that flows through sources like Kafka to end users in a fast and secure manner. Rather than standing up custom solutions, Kiwi lets operators focus on writing business logic, by loading custom WASM plugins that handle tasks like authorization and event filtering per…

kiln – Git-native, decentralized secret management using age▲12
Hi HN, I've been building this tool for the past couple of weeks to solve a problem that seems universal across development teams: sharing environment variables securely. You know the drill - someone needs the staging database URL, so it gets shared over chat. Production API keys end up in plaintext files. Or you set up some complex secret management system that becomes a single point of failure during critical deployments. At Zerodha, we're a stock broker with strict regulatory requirements. Our infrastructure needs to be auditable, and our data must stay with us for instant recovery. But…
