In their own words
Arduino IDE
Arduino IDE is a free desktop environment for building projects with electronic devices that interact with the physical world. The software page lists version 2.3.10, with downloads for Windows, macOS, and Linux. Its editor provides autocompletion, code navigation, and a live debugger; documentation also covers debugging, the Serial Monitor, and the Serial Plotter. Arduino CLI offers a text-based environment to build, compile, and upload sketches, and manage libraries and boards. Documentation describes synchronizing sketches between IDE 2 and Arduino Cloud through a Remote Sketchbook. Arduino IDE 2.0 is open source, with source code hosted on GitHub. Listed targets include Arduino AVR, megaAVR, SAMD, SAM, Mbed OS Nano, and Mbed OS Portenta. Nightly builds preview incoming releases with updated features and bug fixes. Arduino describes its ecosystem as serving students, makers, and professional developers. The software page states that downloads are provided as is and disclaims express and implied warranties.
Replit
Replit is a software creation platform where users can describe applications in natural language and refine them with an AI agent. The agent works through chat, tests and revises code, and can use a browser to produce reports and address issues. Its cloud development environment supports coding and collaboration in a browser, with automatic package installation and built-in authentication, database, hosting, and monitoring. Replit supports websites, mobile projects, designs, slides, animations, data visualizations, 3D, games, documents, and spreadsheets, with more than 100 integrations. The free Starter plan includes daily usage, but limits publishing to one live project and running one background task at a time. Replit Core costs $18 per month billed annually, and Pro costs $90 per month billed annually. Pro supports up to 15 collaborators and 50 viewers, and includes database rollback for up to 28 days. Replit is available on Android, iOS, Linux, macOS, Windows, and web. Its mobile apps support building, sharing, and publishing web apps; native iOS development uses the web version with Expo Go previews.
