Is there a worthwhile analogue of SonarQube?

Question

Software testing

Good afternoon.
I'm trying to choose a platform for checking code for quality.
I opted for SonarQube, because. checks against rules based on programming conventions and standards, supports all major languages ​​we use.
But there is one caveat. If you need to upload enough (more than 1 million) lines of code there, then the solution becomes quite expensive. There is a big price difference there.
Does anyone have experience with such a system?
The wording is such that a direct analogue of SonarCube is needed (it will be cheaper or even open source), which will help reduce the budget in this direction.
Thanks in advance for your replies.

Answer 1

Already five subscribers for a trifling question.
SQ is open source. https://github.com/SonarSource/docker-sonarqube/bl...
Plugins for it are easy to write. Most plugins just import the messages of the checkers launched during the build - the same valgrind or pvs-studio or istanbul.

Answer 2

more than 1 million - what kind of program do you have if it's not a secret?
