Lockval Engine – A distributed backend KV engine that can run scripts
I've been developing game backends for several years, using and designing a lot of code. They all about calculations, synchronization with front-end data, and database data, and try to ensure consistency, atomicity, and high response, etc. However, these codes and frameworks have always had problems such as very complicated APIs, incomplete or non-existent ACID, multiple calls to RPC, and non-real-time full or semi-full data landing. So, we created Lockval Engine. An easy-to-use, ACID, distributed, DOP, multi-language support backend engine. Here are some online demos that will give you a…
Lockval Engine – A distributed backend KV engine that can run scripts launched on February 13, 2023 with 44 votes, #1,232 of 3,829 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Lockval Engine is a distributed key-value database backend designed for game developers that executes scripts across multiple servers. It offers ACID compliance, multi-language support, and simplified APIs to handle calculations, data synchronization, and consistency between frontend and backend systems. The engine aims to reduce complexity in game backend development by minimizing RPC calls and enabling real-time data persistence without the complications of traditional frameworks.

HyperterseFeb 2026 · hyperterse.com · ▲86Hi HN, I’m Samrith, creator of Hyperterse. Today I’m launching Hyperterse 2.0, a schema-first framework for building MCP servers directly on top of your existing production databases. If you're building AI agents in production, you’ve probably run into agents needing access to structured, reliable data but wiring your business logic to MCP tools is tedious. Most teams end up writing fragile glue code. Or worse, giving agents unsafe, overbroad access. There isn’t a clean, principled way to expose just the right data surface to agents. Hyperterse lets you define a schema over your data and…

Talanoa▲343Hi 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…
