## Why another MongoDB client?

This project arose from all flaws of similar tools many of which are slow, complicated, heavy, and fairly unwieldy. They mostly require quite a high level of knowledge on how to operate the program.

**Rolens aims to be the intuitive, lightweight counterpart of these overengineered tools.**

- [x] **Lightweight**: Rolens weighs about 15 MB.
- [x] **Open source**: You know what's inside!
- [x] **Low overhead**: Typical query results against a local database are returned whithin milliseconds.
- [x] **Intuitive interface**: You know MongoDB? You know Rolens.

This project is heavily inspired by the excellent [MongoHub](https://github.com/bububa/MongoHub-Mac) application, which sadly has not been updated since 2011.

Rolens can run on the following operating systems:

* Windows 10/11 amd64/arm64

* macOS 10.13+ amd64 (Intel)

### Pre-compiled binaries

You can obtain a pre-compiled Rolens binary for macOS or installer for Windows from the [release page](https://github.com/garraflavatra/rolens/releases/latest).

### Compiling from source

If you have Node.js installed, just download the source from GitHub, and run `node ./build.js`. The install script will check that dependencies are present and build Rolens for you.

## User guide

Rolens is designed to be as intuitive as possible. But if something is unclear nevertheless, you can consult [the user manual](https://garraflavatra.github.io/rolens/) to learn how to use the program.
