TidesDB – Fast, transactional storage optimized for flash and RAM
Hey hackernews! I'd like to share a hobby and passion project I've been working on for almost a year now. It's an open-source storage engine (underlying component of a database(s)) similar to that of LevelDB/RocksDB but written entirely in C. The storage engine is called TidesDB. TidesDB is written entirely in C. It's designed as a fast, transactional key-value storage engine built on a log-structured merge-tree (LSM-tree) architecture. My journey with TidesDB began nearly 2 years ago whilst I was experimenting with various data structures and databases in Go. When I encountered the…

In plain words
TidesDB is a transactional storage system designed for developers who need fast data access on flash and RAM-based systems. It prioritizes performance and transaction reliability for applications requiring efficient in-memory or flash storage. The product targets software engineers building systems where speed and data consistency are critical requirements. TidesDB is available as open-source software on GitHub.

High-performance write & space optimized transactional storage engine. - tidesdb/tidesdb
TidesDB is a fast and efficient transactional key value storage engine library written in C. The underlying data structure is based on a log-structured merge-tree (LSM-tree). It is not a full-featured database, but rather a library that can be used to build a database atop of or used as a standalone key-value/column store. Join the TidesDB Discord Community to ask questions, work on development, and discuss the future of TidesDB. Multiple licenses apply to TidesDB. The primary license is Mozilla Public License Version 2.0 (TidesDB), while additional licenses apply to the dependencies used in the project.

Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…
Turbolite – a SQLite VFS serving sub-250ms cold JOIN queries from S3Mar 2026 · github.com · ▲185I built a SQLite VFS in Rust that serves cold queries directly from S3 with sub-second performance, and often much faster. It’s called turbolite. It is experimental, buggy, and may corrupt data. I would not trust it with anything important yet. I wanted to explore whether object storage has gotten fast enough to support embedded databases over cloud storage. Filesystems reward tiny random reads and in-place mutation. S3 rewards fewer requests, bigger transfers, immutable objects, and aggressively parallel operations where bandwidth is often the real constraint. This was explicitly inspired…

SpacetimeDB – A database that replaces your server2023 · github.com · ▲80We just released our database, SpacetimeDB, on GitHub under the BSL 1.1 license. It converts to a free software license after a few years. The point of the database is that you upload application logic into the database as a WebAssembly stored procedure, so instead of clients connecting to a webserver they connect directly to the database. The database itself does authentication and you write your own authorization logic just like you would inside a webserver. We’ve developed our game, BitCraft (https://bitcraftonline.com) entirely in this way. All of the game state is stored and…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
