Roku Dev Studio
Roku Developer Tools for macOS, Windows, and Linux — Remote Control, App Side-loading, ECP automation, RALE / App Connector, Network Inspector, Action Scripts, MCP server for AI agents (Cursor, Claude, VS Code), and a rds CLI. Supports both local network and internet-bridged devices.
A comprehensive cross-platform desktop application for controlling and developing on Roku devices over your local network or via remote server using the External Control Protocol (ECP).
This repository is an npm workspace monorepo. Run npm install and npm start from the repository root so workspaces link correctly. Installing runs a postinstall (npm run build:libs) that compiles the shared roku-dev-studio-platform and roku-dev-studio-api packages to their dist/ outputs, which the app and remote server import. Use npm run typecheck for a full TypeScript check across every workspace and npm test to run unit tests. CI runs these plus per-package build/syntax smoke checks on each push and pull request. Setup, scripts, and distributable builds are documented in INSTALLATION.md.
Repository layout
| Location | What it is |
|---|---|
apps/roku-dev-studio/ | Electron desktop app (main process, renderer, packaging). Dev and distributable builds: INSTALLATION.md. |
packages/roku-dev-studio-api/ | Shared Node library + rds CLI: discovery, ECP, screenshots, sideload, RALE, action-script runner, headless validator — package README. |
packages/roku-dev-studio-mcp/ | MCP server that lets AI agents (Cursor, Claude Desktop, VS Code) drive a Roku through this app — package README. |
packages/roku-dev-studio-network-inspector/ | Network Inspector engine: hotspot packet capture (DNS/SNI/HTTP) + local MITM proxy, transport-agnostic so it runs in both the desktop app and the remote server — package README. |
packages/roku-dev-studio-remote-server/ | HTTP/WebSocket relay to control Rokus over the internet — package README. |
packages/roku-dev-studio-platform/ | Shared host-platform helpers (OS identity, modifier keys, path-safe, node-only filesystem helpers) used by the app and other packages so platform logic lives in one place. Built to dist/ on npm install — package README. |
roku-components/ | BrightScript-side artifacts: TrackerTask.xml (drop into your channel for App Connector / RALE) and the fiddle/ SceneGraph scaffold — components README. |

Glossary
| Term | One-line meaning |
|---|---|
| ECP | External Control Protocol — Roku's HTTP API on port 8060 (KeyPress, Launch, Query, Deep-Link). |
| Telnet 8085 / 8080 | The BrightScript debug console (8085) and dev system commands (8080) on a Developer-Mode Roku. |
| RALE | Roku Advanced Layout Editor — Roku's SceneGraph inspection protocol over a TCP socket (default port 49200), spoken by the TrackerTask component. |
| TrackerTask | The BrightScript component channel developers add to their app to make it reachable from RALE / App Connector — see roku-components/README.md. |
| App Connector | The Dev Studio tab that talks RALE: list / call your channel's GetExternalControlFunctions, plus built-ins (node lookup, registry editor, update node). |
| Network Inspector | The Dev Studio tab / engine that inspects a dev channel's HTTP(S) traffic through a local MITM proxy, with optional hotspot packet capture. |
| Sideload | Uploading and installing a .zip / .pkg dev channel onto a Developer-Mode Roku via its Dev Password. |
| Sideload Relay | RDS advertising itself as a Roku so one sideload from your IDE / browser fans out (install → launch → console) to many targeted devices. |
| Action Script | JSON-described automation that chains keypresses, queries, sideload, App Connector calls, screenshots, conditionals, waits, and variables. Built and run from the Action Scripts tab; also runnable headless via rds. |
| MCP server | Roku Dev Studio's Model Context Protocol server — lets Cursor / Claude Desktop / VS Code drive a real device through this app while it's open. Toggle clients in Settings → MCP Server. |
| Fiddle | The BrightScript scratch editor (Monaco + brighterscript lint) that wraps your snippet into a temporary channel and runs it on a selected device. |
rds | The terminal CLI shipped by roku-dev-studio-api (rds discover, rds keypress, rds script run, rds rale repl, …). |

Remote Server Setup
Roku Dev Studio can control devices over the internet using a remote server bridge, so you can manage devices in Remote Locations without being on the same network as the desktop app. Run the relay (npm run remote-server from this repo, or npm install -g roku-dev-studio-remote-server), then add its URL via Add Remote Location in the device selector.
Full setup (running the server as a service, network/firewall configuration, the HTTP/WebSocket API, and Swagger docs) lives in the remote server package README.
