CodeHS vs JDoodle

CodeHS provides computer science curriculum and classroom tools for K–12 teachers, students and schools. Its catalog includes more than 100 customizable, standards-aligned courses across computer science, cybersecurity, artificial intelligence and digital literacy. The browser-based editor supports more than 10 languages, including Python, Java, JavaScript and C++. Classroom tools include autograders, in-editor help, code history and a blocks-to-text experience. Its learning management system gives teachers visibility into class progress, assignment grading and students' coding process. Listed AI features include hints, grading, Ask AI and Vibe Coding; the free-versus-Pro comparison identifies AI grading and hints as Pro features. The permanent Free teacher plan requires no credit card and has no per-student fees, but includes no downloads. Individual Learner All Access costs $99 a month, billed monthly, or $990 a year, billed annually. CodeHS says it is not an accredited school or online course provider, so Individual Learner students do not receive official grades or academic credit upon completion. Most integrations require a school license.

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.
