JDoodle vs Theia IDE

JDoodle is an online programming platform for learning, teaching and practicing code. Its browser IDE runs programs on JDoodle machines, so it requires no local IDE installation, and it supports 114 languages, frameworks and databases. The Compiler API provides REST for final results and WebSocket for streaming output and interactive programs; API and embedded submissions run with time and memory limits. Runnable IDEs can be embedded in websites, course materials and learning management systems using three lines of HTML. Education features include assignments, automated correction and grading, question types, roles and result disclosures. Mobile apps support writing and running code on iOS and Android phones and tablets. The free Chrome extension has no Firefox or Safari version. The Free platform plan does not expire and needs no credit card; it includes 1,000 executions per day and 100 saved projects. A separate API Free plan gives 20 credits per day and no internet access. Pro costs $15 a month, and Student costs $4 a month billed yearly (US$48 a year). Paid API tiers start at $10 a month.

Theia IDE is an open-source, AI-native development environment for cloud and desktop, built on the Theia Platform. Users can select cloud, self-hosted or local AI models and create custom agents. It integrates official SDKs for providers including OpenAI, Anthropic and Google, and sends AI data to the provider the user chooses. The IDE supports VS Code extensions through Open VSX, though some Microsoft-proprietary extensions are unavailable and some extension API features may not work as expected. Language support uses the Language Server Protocol, including for Python, Java, JavaScript and C++. Workspace Trust puts untrusted folders in Restricted Mode and disables features that could execute code or read sensitive workspace content, but the project says this protection is still maturing. The IDE does not collect or transmit user activity, project details or code, though it can check for IDE and extension updates. The ready-to-use IDE is free at free. Its online demo is limited to 30 minutes per session. The modular Theia Platform can be used to build customized or white-labeled cloud and desktop IDEs and tools.
