JDoodle
Verified Oct 16, 2026 ActiveBrowser IDE and compiler for 110+ languages, with an embeddable compiler API for course sites

Pricing
- Pricing model
- Freemium
The core compiler is free to use in the browser without an account. A Pro upgrade and separately metered compiler API plans exist, but the pricing page renders entirely client-side and returns no plan names or figures to a plain request, so no entry price is recorded.
Use tool ↗About JDoodle
JDoodle is an online compiler and IDE covering more than 110 programming languages, so you can write, run and share code without installing a toolchain. Beyond the free scratchpad it sells a Pro tier and a compiler API that education platforms embed to run student code inside their own courseware — the company says it serves over a million coders and more than ten thousand education institutions. There are iOS and Android apps for saving and running projects on a phone. The site now markets itself as an AI-assisted coding platform alongside the plain compiler. It is built by JDoodle Labs Pty Ltd in Australia, founded by Gokul Chandrasekaran and backed by Main Sequence, the venture firm founded by Australia's national science agency.

Pros & cons of JDoodle
JDoodle is the workhorse of this category — 110+ languages, no install, works on a school network — and its real business is the compiler API that course platforms embed to grade and run student code. That gives it a durability most browser IDEs lack. The AI framing is newer and thinner than the compiler itself, and none of the paid tiers publish a readable price.
Pros
- More than 110 languages runnable in the browser with no signup for the basic compiler
- A documented compiler API that other platforms embed for code execution
- iOS and Android apps let you save, run and share projects from a phone
- Backed by Main Sequence and used by 10,000+ education institutions, per the vendor
Cons
- The pricing page is client-rendered and shows nothing to a plain request, so plans cannot be compared before signing in
- The AI assistance is a recent addition and much less documented than the compiler
- It is a scratchpad — no real project structure, dependency management or version control
- Execution limits on the free tier are not published on the marketing site
Best for
- Running a quick snippet in a language you do not have installed
- Education platforms that need code execution embedded in their own courseware
- Teaching environments where students cannot install a toolchain
Not for
- Real project work — this is a scratchpad, not a development environment
- Anyone evaluating on price without creating an account first
Watch out: The compiler API is metered separately from the Pro subscription, so an embedded classroom deployment is a different bill from a personal upgrade.
