Arduino Cloud Editor vs TypeScript Playground

Arduino Cloud Editor lets users read, edit, and verify code for Arduino Cloud projects in a browser, including projects set up through Arduino Cloud. Its experimental AI Assistant helps write sketch code and is included across Cloud plans, with different monthly interaction limits. The Free plan costs nothing and includes two Things, five variables per Thing, 25 compilations per day, and 30 AI interactions per month. Annual plan prices listed are $72 a year for Maker, $1,000 a year for Team, and $20 a year for School; Enterprise has no listed price. Physical board connections on Windows, macOS, and Linux require the Arduino Cloud Agent. ChromeOS can create and upload sketches, though board support is limited to compatible boards. Arduino Cloud supports remote code uploads and dashboard sharing with viewer or editor access. Amazon Alexa voice control is available, and the School plan lists Google Classroom integration. Arduino says plan features are subject to fair-use limits, including caps on variables, sketch storage, and sketch files. Maker is intended for personal use; business and school users are directed to corresponding plans.

TypeScript Playground is a free browser environment for writing, running, sharing, and safely experimenting with TypeScript and JavaScript. It accepts .ts, .tsx, .js, .jsx, and .d.ts files. Run converts code to JavaScript, executes it in the current browser session, and shows console output in Logs; the browser session can also support DOM API experiments. The editor centers on one text document and is described as a teaching tool that needs no setup. Users can select supported TypeScript builds, including beta, nightly, pull request, and older builds. The TS Config panel exposes a focused compiler-option set, while twoslash annotations can configure options beyond it. URLs can preserve code, compiler flags, and settings for sharing. Export can create Markdown, open TypeScript AST Viewer, or export a project to CodeSandbox or StackBlitz. Plugins are supported, including Presentation Mode, Clippy, TSQuery, Collaborate, and Transformer. The mobile layout uses a single pane and does not show transpiled JavaScript beside source.
