Qala is built with the best industry practices and with compatibility in mind. Therefore most third party plugins should work with Qala as long as they are also built with good practices. Qala even utilises the strength of the open source community of WordPress and uses well written third party plugins as part of its package. Not doing so would be going against the open source ethos. However, since Qala is all about quality and stability we continuously evaluate third party plugins if they are safe to use and compatible with Qala as well as unique features for your site. We also acknowledge that you decide to partner with us for our expertise and as such we like to help you pick third party plugins that not only work with Qala, but also align with the business problems you aim to solve.
