webR compared with RStudio, Posit Cloud and Google Colab| 웹R | RStudio | Posit Cloud | 구글 콜랩 |
|---|
| Where the code runs: R is compiled to WebAssembly and executes inside the browser tab, so no R installation and no R server are needed. Data loaded in the session stays on the client machine. | Where the code runs: The desktop edition runs R locally. RStudio Server and Posit Workbench provide the same IDE in a browser, with R executing on a server. | Where the code runs: R runs in a per-project container hosted on AWS and the IDE is opened in the browser. Project data is encrypted at rest on the provider side. | Where the code runs: Code runs on virtual machines operated by Google. Notebooks are stored in Google Drive or loaded from GitHub, and sharing a notebook does not share the VM or its files. |
| Language support: Runs the R language, plus a TypeScript and JavaScript API for driving the R console and R objects from a web page. | Language support: Integrated environment for R and Python, with a visual editor for Quarto and RMarkdown, an interactive debugger and package development tools. | Language support: Offers RStudio for R and Jupyter Notebooks for Python in the browser. | Language support: Focuses on Python and its ecosystem. According to the FAQ, R and other non-Python kernels are not supported, and no timeline is given. |
| Limits and persistence: Packages can only be installed as precompiled WebAssembly binaries, not from source, and they are reinstalled in every session. The system() command is not implemented and each session starts with a clean slate. | | Limits and persistence: Usage is measured in compute hours that depend on allocated RAM and CPUs, and projects are suspended after 15 minutes without activity. Plans range from 1 to 8 CPUs and from 1 to 32 GB of RAM. | Limits and persistence: Limits are dynamic and not published. Free notebooks can run for at most 12 hours, idle runtimes time out, and GPU and TPU availability varies over time. |
| 라이선스 및 비용 모델: Built on the open-source R interpreter and delivered as web pages, so it can be hosted on an ordinary web server such as GitHub Pages. | 라이선스 및 비용 모델: The open source edition is under the AGPL. Commercial variants exist, and the Posit Workbench commercial licence removes the AGPL restrictions. | 라이선스 및 비용 모델: Free plan that does not expire, with paid plans above it. Some plans cap monthly compute hours. | 라이선스 및 비용 모델: Free of charge with GPUs and TPUs included. Paid Pro, Pro+ and Pay As You Go plans add compute availability, longer runtimes and high-memory machines. |
| 플랫폼 및 접근 방식: Needs a modern browser. The webr canvas graphics device requires OffscreenCanvas, while Cairo-based devices such as png() also work in older browsers. | 플랫폼 및 접근 방식: Desktop runs on Windows 11, macOS 14 or later and Linux. Server and Workbench are reached through a browser. | 플랫폼 및 접근 방식: Accessed through posit.cloud with an authenticated login. | |
