JDoodle

Overview

JDoodle is an online coding workspace with tools for teaching, embedded editors and programmatic code execution. It is a strong fit for students and teachers who need more than a code runner, and for developers who want to run code in a browser or integrate execution into another product. Its free options make it easy to start, but the platform and API have separate quotas and paid plans.

Key features

The browser IDE runs programs on JDoodle’s machines, so there is no software to install locally. Its support for 114 languages, frameworks and databases gives learners and developers a broad place to experiment. Full-stack runtime scope, real-time collaboration and public sharing make it useful beyond one-off snippets, though hosted execution is subject to time and memory limits.

For coursework, JDoodle offers assignments, automated correction and grading, different question types, roles and result disclosures. That combination suits teachers managing structured practice and assessment better than a standalone code runner. Developers can also embed a runnable IDE in a website, course material or learning management system with three lines of HTML.

The Compiler API provides REST responses for final results and WebSocket streaming for interactive programs. API and embed submissions run on JDoodle machines with bounded time and memory, so it offers a way to add hosted execution without running submissions on a user’s own machine. The free Chrome extension is useful for browser-based access, but there is no Firefox or Safari version. Mobile apps let users write and run code on iOS and Android phones and tablets.

Pricing

JDoodle has several plans for distinct uses. The Free platform plan costs nothing, is free forever and requires no credit card. It includes 1,000 code executions per day, 100 saved projects and one collaborator per project. That is a workable starting point for individual learning and small projects, but the project cap and daily quota may constrain heavier use.

Pro costs $15 a month, billed monthly, and includes 150 AI credits a month, 10 collaborators per project and five Premium Embed IDEs. It suits users who need more collaboration or premium embeds; the listed inclusions do not specify a higher execution quota. Student costs $4 a month, billed yearly at US$48 a year, and adds unlimited executions and saved projects, 50 AI credits a month, twice the standard workspace and 10 collaborators per project. Its annual billing is a meaningful commitment, though the unlimited executions and projects make it a better fit for sustained student use.

Teacher has custom pricing and unlimited collaborators per project, assessments and students, fitting educators running courses at scale. Enterprise also has custom pricing, with SSO, invoice payment, advanced user management and priority support for organizations that need those administrative options.

The API has its own plans. API Free costs nothing and provides 20 credits per day, no internet access, REST and WebSocket APIs, and all languages. API Starter costs $10 a month for 1,000 credits per day and internet access; API Growth costs $20 a month for 2,000 credits per day and internet access; API Scale costs $50 a month for 5,000 credits per day and internet access. The free API tier is useful for limited experiments, while the paid tiers suit integrations that need internet access or greater daily volume.

Platforms

JDoodle is available on the web, Android and iOS, with an API and a browser extension. The extension is limited to Google Chrome. The company says it primarily stores personal information in Australia and the United States and uses security measures against unauthorized access. Stripe processes credit card payments; JDoodle says it does not store or handle card details in its systems. Its support team answers customer questions directly and provides documentation.

Who it's for

JDoodle is most compelling for students, teachers and developers who benefit from combining browser-based coding with education tools, embeddable IDEs or an execution API. Teachers can use its assessment features, and developers can choose an API plan by daily credit needs. It is less suitable for someone who needs a locally installed environment, or for users who require a Firefox or Safari extension.

Pros and cons

• Pros: The free platform plan does not expire or require a card, and allows 1,000 executions per day.
• Pros: Support for 114 languages, frameworks and databases serves varied learning and development needs in one browser IDE.
• Pros: Assignments, automated grading, embeds and REST or WebSocket API access cover classroom and integration use cases.
• Cons: The free platform plan caps saved projects at 100 and collaborators at one per project.
• Cons: API Free is limited to 20 credits per day and has no internet access.
• Cons: The browser extension works only with Chrome.
• Cons: Student pricing is billed yearly, while Teacher and Enterprise require custom pricing.

Alternatives

Choose CodeHS if a free teacher plan with 100+ courses and automatic code submission and section management is a closer match for your classroom. OneCompiler is worth considering if unlimited code executions on its free plan matter more than JDoodle’s education and collaboration features; its free tier also includes 20 AI credits per day. Playcode offers a free plan with three projects or published sites and one collaborator, plus a free trial, for users comparing browser-based coding options.

Replit has a free Starter plan with daily usage and one live project and background task at a time. CodePen is an alternative for public web projects, with unlimited public Pens and three files per Pen on its free plan. Scratch is a free platform for creating and sharing projects. CodePad is another free option. Google Colab is an alternative if notebook-based work is the priority; its free plan has no guaranteed access to compute units and limited GPU access.

Verdict

Choose JDoodle if you want a lasting free browser coding environment, especially when coursework, collaboration, embeds or API execution are part of the job. Its breadth is a practical advantage, but the split plan structure, daily limits and Chrome-only extension give users with heavier or more specialized needs good reason to compare alternatives.
