You can evaluate CLion for up to 30 days. After installing the IDE, log in to your JetBrains Account to start using the CLion's trial version.

tip

  • CLion will automatically log you into your JetBrains Account if you're using ToolBox to install JetBrains products and already logged in there.

  • If you use two-factor authentication for your JetBrains Account, you can specify the generated app password instead of the primary JetBrains Account password.

Start the free trial

  1. In the Licenses dialog that opens when you start CLion, select the Start trial option and click Log in to JetBrains Account. You will be redirected to the JetBrains Account website.

  2. Log in to your JetBrains Account on the website and click the Start Trial button in the Licenses dialog to start your trial period.

Upon the expiration of the trial version, you need to buy and register a license to continue using CLion . A new trial period will be available for the next released version of CLion.

Activate CLion license

  1. Do one of the following to open the Licenses dialog:

    • From the main menu, select Help | Register

    • On the Welcome screen, click Help | Manage License

    CLion: Licenses dialog

  2. If necessary, log in to your JetBrains Account.

  3. Select how you want to register CLion or a plugin that requires a license:

    Register using the JetBrains Account.

    CLion will automatically show the list of your licenses and their details like expiration date and identifier. Click Activate to start using your license.

    If your license is not shown on the list, click Refresh license list.

    tip

    CLion detects the system proxy URL during initial startup and uses it for connecting to the JetBrains Account and Floating License Server. To override the URL of the system proxy, add the -Djba.http.proxyJVM option. Specify the proxy URL as the host address and optional port number: proxy-host[:proxy-port]. For example: -Djba.http.proxy=http://my-proxy.com:4321.

    If you want to disable proxy detection entirely and always connect directly, set the property to -Djba.http.proxy=direct.

Early Access Program

Pre-release builds of CLion that are part of the Early Access Program are shipped with a 30-days license. Log in with your JetBrains Account to start using CLion EAP.

Login options

  1. Click Log in to JetBrains Account. You will be automatically redirected to the JetBrains Account website.

    Log in with an existing account

Access to JetBrains Account: Troubleshooting

If you encounter problems when attempting to log in to your JetBrains Account, this may be due to one of the following reasons:

No free ports

Unable to open JetBrains Account in your browser

No access to JetBrains Account

Log in with an authorization token

An authorization token is a way to log in to your JetBrains Account if your system doesn't allow for redirection from the IDE directly, for example, due to your company's security policy. CLion recognizes when redirection to the JetBrains Account website is impossible. It enables you to copy a link to generate an authorization token manually.

  1. Click Copy link and open the copied link in your browser.

  2. Log in to your JetBrains Account to generate an authorization token. After that, copy the token, paste it to the IDE authorization token field and click Check token. Once you've successfully logged in, you can start using CLion.
