rbxport

rbxport is a music library management app inspired by rekordbox. It keeps its feature set deliberately small, aiming for a faster, simpler user experience.

Its scope is limited to library management, USB exporting, and PRO DJ LINK.

Project vision

The core vision of rbxport is fewer features.

Because rbxport is open source, you are free to fork it and build a version of rekordbox customized by the community. The core project does not aim to be that. A project that keeps adding features eventually becomes what rekordbox already is: full-featured DJ software. rbxport stays small on purpose. Any contribution that adds a feature is weighed carefully against this vision, and a good feature can still be declined.

Two commitments define what "small" must not cost:

• Compatibility. rbxport aims to be fully compatible with the current version of rekordbox and all the hardware that rekordbox supports.
• Performance. rbxport maintains its speed through a performance budget, defined in perf-budgets.json and enforced by pnpm budget and CI. See Development conventions.

If you want to propose a feature, read Feature proposals in the contributing guide first.

Tech stack

See Architecture for the repository layout and how the frontend, desktop shell, and Rust crates fit together.

Start here

For a first look at the interface, use the browser with a mock library:

pnpm install
pnpm dev:web

This requires Node 24 and pnpm 10.17.1. It does not open an installed rekordbox library or require a Rust build. For desktop prerequisites and safe library setup, read Getting started.

Developer reading path

Read these in order to understand the project and make your first change:

1. Getting started: prerequisites, run modes, and library safety.
2. Architecture: repository map, crate responsibilities, IPC, and edit flow.
3. Development conventions: code style, performance, translation, and evidence rules.
4. Testing: checks, test setup, and what each result proves.
5. Contributing: issues, branches, implementation, validation, and review.
6. Debugging: logs, diagnostics, environment variables, and cleanup.
7. Releases: versions, CI, packaging, and publication.

The documentation index also links to user guides and detailed analysis, USB-format, and hardware references.
