Started as a side project, JDoodle, which lets developers practice more than six dozen programming languages on one website, hit 800,000 users while being bootstrapped. Now the Sydney, Australia-based startup has set a goal of 8 million users within the next 24 months after getting $3.2 million AUD (about $2.2 million USD) in new funding. The round was led by Main Sequence, the venture firm founded by Australia’s national science agency.

JDoodle has tools aimed at software developers of all levels, ranging from students to professionals. These include zero-set up IDEs (integrated development environments) for more than 76 coding languages, including Java CloudIDE, that lets users write and run code in their browsers without having to set up local software or libraries.
