Could anyone please let me know if there is any limit to store number of projects in SonarQube with Community Edition or is it unlimited?
The only limit is the sky with SonarQube CE. Keep in mind that once you move to another commercial editions, the system looks at the number LOCs analyzed to compute the bill.
The more you analyze projects with SonarQube, the more you will need enterprise features such as Portfolios.
Thanks for your answer, we wanted to play around CE and present demo.
