Nitrous.io built a business around offering a cloud-based integrated development environment (IDE) in which software developers could work on source code and even share their work with teammates. However, today the startup announced in its company newsletter that the cloud IDE will go away on November 14. As of today, Nitrous will stop taking on new users.

Payments made after October 16 will be refunded, the startup said in the email. People with existing projects will be sent an email with a link to download their data, but after 15 days the data will be deleted.

“We will send an update on our free and open-source Nitrous Solo IDE in the coming weeks,” the company said.

There are other cloud-based IDEs, including Eclipse Orion, which was recently incorporated into the Google Cloud Shell, and Koding. Startup Codeanywhere also offers a cloud IDE.

The reason for Nitrous’ shutdown is not clear, and indeed its homepage doesn’t say anything about the news. But earlier this year, public cloud market leader Amazon Web Services (AWS) acquired another cloud IDE startup, Cloud9.

Some developers might not like to rely completely on a machine that’s running remotely. Nitrous does offer a Nitrogen plugin for GitHub’s open-source Atom text editor.

Nitrous.io was founded in 2012, with offices in San Francisco and Singapore. Investors include 500 Startups, Bessemer Venture Partners, CrunchFund, Draper Associates, Golden Gate Ventures, Lion Rock Capital, and Eduardo Saverin. The startup announced a $6.65 million round in March 2014.
