JDoodle

JDoodle is a hosted programming workspace with a browser IDE, classroom tools, embeddable editors and a Compiler API. It is best suited to learners and teachers who want coding and assessment together, or developers who need hosted code execution. Its free platform plan supports ongoing work, but project caps and separate API quotas make the right tier depend on how you use it.

Overview

JDoodle brings several programming uses into one service: writing and running code in a browser, managing coursework, embedding runnable editors and calling a compiler through an API. The breadth is useful for classes that mix practice with assessment and for developers building interactive code experiences. It is less compelling if you need only a local development environment or want to avoid hosted execution limits.

Key features

The browser IDE runs programs on JDoodle machines and requires no installation. Its support for 114 languages, frameworks and databases makes it a versatile place to learn or try different technologies. Full-stack runtime scope, real-time collaboration and public sharing extend the workspace beyond private snippets, though code still runs under bounded time and memory limits.

Education features include assignments, automated correction and grading, varied question types, roles and control over result disclosures. That combination is a meaningful advantage for teachers organizing structured practice and assessment; casual users who only need a compiler may not benefit from the extra classroom tools.

JDoodle embeds can add a runnable IDE to a website, course material or learning management system with three lines of HTML. The Compiler API offers REST for final results and WebSocket for streaming output and interactive programs. Both API and embed submissions execute on JDoodle machines with bounded time and memory, a practical fit for hosted code experiences but not unrestricted execution.

Mobile apps let users write and run code on iOS and Android phones and tablets. The free Chrome extension adds another way to work in the browser, but it is not offered for Firefox or Safari.

JDoodle Labs Pty Ltd says it primarily stores personal information in Australia and the United States and uses measures to prevent unauthorized access. Stripe processes credit cards, which JDoodle says it does not store or handle in its own systems. The company says its support team answers customer questions directly and provides documentation.

Pricing

The platform and Compiler API have separate free plans and quotas, so a free platform account should not be mistaken for unlimited API use.

Free: free, billed Free forever, with no credit card required. It includes 1,000 code executions per day, 100 saved projects and one collaborator per project. This is a useful ongoing tier for individual practice, but the project ceiling and single-collaborator limit constrain larger shared work.

Pro: $15 a month, billed monthly. It adds 150 AI credits a month, 10 collaborators per project and five Premium Embed IDEs. Choose it when collaboration or premium embeds matter; its stated inclusions do not give the unlimited executions and projects offered by Student.

Student: $4 a month, billed billed yearly, or US$48 a year. It includes unlimited executions and saved projects, 50 AI credits per month, 2× standard workspace and 10 collaborators per project. The yearly commitment is central to the low monthly equivalent; it is a strong fit for students who need room beyond Free’s caps.

Teacher: custom pricing, with unlimited collaborators per project, assessments and students. It suits educators managing classes at scale.

Enterprise: custom pricing, with SSO, invoice payment, advanced user management and priority support. Those organizational controls make it the relevant option for larger deployments.

API Free: free, with 20 credits per day, no internet access, REST and WebSocket APIs, and all languages. It allows evaluation and low-volume use, but the daily quota and offline-only access limit production use.

API Starter: $10 a month for 1,000 credits per day and internet access.

API Growth: $20 a month for 2,000 credits per day and internet access.

API Scale: $50 a month for 5,000 credits per day and internet access. The paid API tiers step up daily capacity while retaining internet access.

The platform Free plan is not a trial, does not expire and requires no card. JDoodle offers no free trial.

Platforms

JDoodle runs on the web and offers iOS and Android apps, a Chrome extension and an API. The extension's Chrome-only support is a drawback for users committed to Firefox or Safari. Mobile access is useful for writing and running code on phones and tablets, while the browser IDE avoids local installation.

Who it's for

JDoodle is a good match for students who want a browser-based coding workspace and can use the annual Student billing, and for teachers who need assignments, grading and classroom management. Developers should consider it when they need hosted execution, embeddable IDEs or REST and WebSocket compiler access, while checking the relevant execution bounds and API quota. It is a weaker fit for users whose primary requirement is a local IDE, or whose workflow depends on a non-Chrome extension.

Pros and cons

Pro: The Free platform plan persists without a card and permits 1,000 daily executions, making it useful for regular practice rather than a short trial.

Pro: Education tools combine assignments with automated correction and grading, which supports structured teaching beyond simple code execution.

Pro: REST and WebSocket API options, plus quick-to-add embeds, cover both final-result and interactive code experiences.

Con: Free platform projects cap at 100 and collaboration at one person per project, limiting shared work unless you upgrade.

Con: Student is billed yearly despite its monthly display, so the US$48 annual payment is the meaningful commitment.

Con: The API Free plan allows only 20 credits per day and no internet access, requiring a paid API tier for higher quotas and internet access.

Con: The browser extension is limited to Chrome, leaving Firefox and Safari users without that option.

Alternatives

For a different coding playground, compare Code Playground Software and Coding Playgrounds.

Playcode is another freemium option with a free plan and trial; its free tier allows three projects or published sites, one collaborator and requires Playcode branding.

Replit is worth considering if you want a free daily-usage tier with one live project and one background task at a time.

Scratch is a free platform for creating and sharing projects; its Annual Membership costs $35 a year.

CodeHS may suit teachers looking for a permanent free teacher plan with 100+ courses, a browser-based editor and automatic code submission and section management.

OneCompiler offers unlimited code executions and 20 AI credits per day on its free plan, making it an alternative for users prioritizing those free-tier limits.

CodePad is a free alternative for iOS and web.

CodePen may be a better fit for public front-end examples: its free plan includes unlimited Public Pens and three files per Pen.

Observable is an alternative with web and self-hosted platforms.

Verdict

Choose JDoodle if you are a student or teacher who wants code execution and education tools in one hosted service, or a developer who needs embeddable editors or a compiler API. Its durable free platform tier and broad language support are the main draws. Look elsewhere if you need a local IDE, more than 100 projects or one collaborator without upgrading, or API use beyond the free tier's tight daily quota and lack of internet access.
