RLPeak

RLPeak is an open-source Windows desktop companion for Rocket League, built around a simple, no-runtime-injection approach.

RLPeak V1 (current release line: V1.1.0) focuses on item customization with Decals, Wheels, and Boosts. More tools and plugins are planned for future versions.

V1 provides a fast workflow for decals, wheels, and boosts with:

• one-click Apply
• one-time original backups
• reset to original files
• local state persistence
• no runtime injection.

What RLPeak Is Not

RLPeak does not:

• inject DLLs
• inject into RocketLeague.exe at runtime
• perform runtime injection
• edit game memory
• add runtime hooks
• bypass anti-cheat.

Trust Model

RLPeak is open source so users can verify how it works before running it.

Core trust points:

• downloads happen only when the user clicks Apply
• downloaded files are asset files only and are not executed
• local backups are created before replacement
• reset can restore original files from local backups
• remote API access is scoped to the official RLPeak domain.

Privacy: Anonymous Usage Metrics

RLPeak includes an optional anonymous usage metrics client to help understand real app usage and improve reliability.

What RLPeak sends:

• app lifecycle/action event names (for example app start, plugin actions, apply success/failure)
• app version
• platform
• anonymous random install ID (UUID)
• optional plugin ID and safe generic error code.

What RLPeak does not send:

• Rocket League account data
• Windows username
• local file paths
• Rocket League path
• hardware fingerprints
• raw logs or raw stack traces.

Control:

• Users can disable anonymous usage metrics anytime in Settings.

Remote Delivery Model

Production API domain:

• https://api.rlpeak.com

Primary endpoints:

• Manifest: https://api.rlpeak.com/v1/manifest.json
• Startup version gate: https://api.rlpeak.com/v1/app/version.json

Behavior:

1. RLPeak fetches catalogs from the manifest URLs.
2. Catalog JSON is cached locally in AppData/catalogs.
3. Item files are downloaded only when the user clicks Apply.
4. Downloaded item files are treated as assets and are not executed.
5. Downloaded files are cached under AppData/cache/ItemsFiles.
6. Apply copies from cache/local compatibility sources into Rocket League.

Downloads are user-triggered and use HTTPS only.

Local Backup and Reset

Before replacing a game file, RLPeak creates a one-time backup (if missing):

• AppData/Backups/originals/...

Reset restores originals from backups and works offline.

Version Gate

On startup, RLPeak validates the installed app version against:

• https://api.rlpeak.com/v1/app/version.json

If outdated or unavailable, app routes remain blocked until version checks pass or user retries/updates.

Build From Source

Requirements:

• Node.js + npm
• Rust toolchain
• Tauri prerequisites for Windows

Build-only prerequisites for the default tracker.gg browser-impersonation path (mmr-wreq):

• NASM (nasm.exe) for BoringSSL assembly during compile
• LLVM/Clang (libclang.dll) for bindgen used by boring-sys2

Runtime note for end users:

• RLPeak packaged app does not require NASM, Rust, Node, Python, or build toolchains at runtime.
• These prerequisites are for developers/build machines only.

Install dependencies:

npm install

Run in development:

npm run tauri:dev

Run validation:

npm run lint
npm run typecheck
npm run test
npm run build
cargo check --manifest-path src-tauri/Cargo.toml

Build Windows package:

npm run package:release

Debug package:

npm run package:debug
