Vix kv Vix kv is a durable, local-first key-value engine built for real-world systems. It provides crash-safe writes, deterministic state, and a simple API. 🌍 https://vixcpp.com 📘 Getting Started • API • Why kv

Built for the real world

Most databases assume stable networks and perfect infrastructure.

Reality is different.

kv is designed for:

• unreliable networks
• offline environments
• crash scenarios

Write locally. Persist first. Read instantly.

---

Why developers use kv

• no data loss
• instant reads
• no server dependency
• works offline
• simple API

---

Features

• Structured keys ({"users","42"})
• Binary-safe values
• WAL-backed durability
• Prefix scan
• Crash recovery
• Embedded (no server required)

---

Quick example

#include <vix/kv/kv.hpp>

int main()
{
  auto db = vix::kv::open();

  db.set({"users","42"}, "Alice");

  auto value = db.get({"users","42"});

  if (value)
  {
    std::cout << value->to_string() << std::endl;
  }
}
