Why Ramify JS?

Designed for fast filtering, sorting, and live queries in in-process JavaScript runtimes.

In-Memory Performance

Lightning-fast queries with data stored entirely in memory. No network latency, no disk I/O.

Live Query Observation

Observable queries with optional React hooks for automatic UI updates.

TypeScript-First

Full type safety with intelligent autocomplete. Catch errors at compile time, not runtime.

Powerful Queries

Fluent API with filtering, sorting, pagination. Query like a pro.

Indexed Collections

Create indexes for lightning-fast lookups. Support for multi-entry indexes on array fields.

Zero Dependencies

Minimal footprint with no external dependencies. Just pure, efficient JavaScript.

Run Anywhere JS Runs

A unified in-memory data engine across JavaScript runtimes

Browser

Reactive Client Apps

The primary engine for fast UIs. Use live queries to keep your views in sync with local data automatically.

Edge

Request-Scoped Cache

Fast lookups for Cloudflare Workers or Vercel Edge. Filter and sort upstream API data with zero latency.

Node.js

In-Process Services

Perfect for hot data management, background jobs, or complex data transformations in long-running processes.
