Overview

JDoodle is an online coding workspace with a browser IDE, tools for teaching and assessment, embeddable editors and a compiler API. It suits learners and educators who want coding and coursework together, as well as developers who need hosted execution across many languages. Its permanent free platform tier makes it practical to keep using, but platform and API plans have separate limits that should shape the choice.

Key features

The browser IDE runs programs on JDoodle’s machines without requiring a local install. Its support for 114 languages, frameworks and databases gives students and developers a broad place to experiment; it is less suitable when code must run on locally managed infrastructure. Full-stack runtime scope, real-time collaboration and public sharing also make it useful beyond one-off snippets.

For teaching, JDoodle offers assignments, automated correction and grading, varied question types, roles and result disclosures. That combination is more useful for organizing coursework than a code runner alone. Teachers who need unlimited collaborators, assessments and students will need the Teacher plan, while an individual learner can start with the free platform tier.

Embeds put a runnable IDE into a website, course material or learning management system with three lines of HTML. The Compiler API provides REST for final results and WebSocket for streaming output and interactive programs. API and embed submissions run on JDoodle machines with bounded execution time and memory, so the hosted environment is convenient but not an unconstrained runtime.

The iOS and Android app supports writing and running code on phones and tablets. The free Chrome extension adds another browser workflow, but there is no Firefox or Safari version. JDoodle says it primarily stores personal information in Australia and the United States and uses measures against unauthorized access; Stripe processes card payments, and JDoodle says it does not store or handle card details in its systems.

Pricing

The platform and API have separate plans, so a platform subscription should not be treated as API capacity. The platform Free plan is 0.00 USD per free, billed Free forever, with no credit card required. It allows 1,000 code executions per day, 100 saved projects and one collaborator per project. That is a substantial starting point for individual practice, but the one-collaborator limit constrains shared work.

Pro costs 15.00 USD per month, billed monthly, and includes 150 AI credits a month, 10 collaborators per project and five Premium Embed IDEs. It makes sense for users who need more collaboration or premium embeds, though the listed plan terms do not state execution or saved-project allowances. Student costs 4.00 USD per month, billed yearly at US$48 a year, and includes unlimited executions and saved projects, 50 AI credits per month, a 2× standard workspace and 10 collaborators per project. Its annual billing is a lower-cost route for students who need those higher limits, but requires a yearly commitment. Teacher has custom pricing and includes unlimited collaborators per project, assessments and students. Enterprise also has custom pricing, adding SSO, invoice payment, advanced user management and priority support for organizations with those needs.

The API Free plan is 0.00 USD per free and provides 20 credits per day, no internet access, REST and WebSocket APIs, and all languages. It is suited to small experiments, not connected workloads. API Starter costs 10.00 USD per month for 1,000 credits per day and internet access; API Growth costs 20.00 USD per month for 2,000 credits per day and internet access; API Scale costs 50.00 USD per month for 5,000 credits per day and internet access. Choose among them by daily credit demand rather than platform collaboration needs. JDoodle has no free trial; its platform Free plan is not a trial, does not expire and does not require a card.

Platforms

JDoodle is available on web, iOS and Android, with an API and a free Google Chrome extension. Its private-project limit is 25. The platform Free plan’s 100 saved projects and the 25-project limit are distinct caps, so users managing private work should account for both.

Who it's for

JDoodle is a strong fit for students who want broad language support and generous ongoing practice limits, and for teachers who need assignments and automated grading. Developers can use it for hosted code execution, interactive API workflows or runnable embeds, provided the execution bounds and API credit limits fit their use. It is a weaker fit for teams that require local execution, or for Chrome-extension users who rely on Firefox or Safari.

Pros and cons

Pros: The free platform plan is permanent and includes 1,000 daily executions and 100 saved projects, supporting regular individual use without a subscription.
Pros: Education tools combine assignment management with automated correction and grading, useful for structured classes.
Pros: REST and WebSocket API options cover both final results and interactive output, while embeds can add a runnable IDE to learning materials.
Cons: The API Free tier is limited to 20 daily credits and has no internet access, so connected or higher-volume use requires a paid API plan.
Cons: Hosted submissions have bounded time and memory, and the free Chrome extension does not support Firefox or Safari.
Cons: Private projects are capped at 25, even though the platform Free plan allows 100 saved projects.

Alternatives

Consider CodePen when the work centers on public web pens: its free plan offers unlimited public Pens, while its Starter plan costs 8.00 USD per month and allows 50 files per Pen and 5 MB media files. Choose Google Colab when notebook work and GPU access are the priority; its free Colab plan has no guaranteed compute-unit access and limited GPU access, while Colab Pro is 8.33 USD per month on an annual/fixed-term plan.

StackBlitz is another browser coding alternative. Val Town is worth considering for public vals and scheduled runs: its free plan includes 100,000 runs per day, 15-minute cron intervals and one-minute wall-clock time per run. JS Bin is another option for browser-based coding.

For classroom use, compare CodeHS, whose permanent free teacher plan includes 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 uncapped execution and basic AI use. Replit is another freemium coding platform to consider.

Verdict

JDoodle is a good choice for students, teachers and developers who want a broad-language browser IDE alongside education tools, embeds or a compiler API. The enduring free platform plan and specialized workflow options are its strongest reasons to choose it. Look elsewhere if you need local execution, broader browser-extension support or API access without tight free-tier limits.
