Bootstrap has no language dependency of its own: it's built from HTML, CSS, and a JavaScript bundle that's dropped jQuery since Bootstrap 5 in 2021, so it works with whatever server-side language renders the HTML it styles. That covers PHP, Python, Ruby, Java, C#, Node.js, and Go, since all of them can output the markup Bootstrap's classes attach to.
What does that mean in practice?
Adding Bootstrap to a project looks the same regardless of backend language: link the stylesheet, optionally load the JavaScript bundle for components like modals and dropdowns, and apply Bootstrap's classes to whatever HTML the backend generates. A Laravel app, a Django app, and a plain PHP script all include Bootstrap the same way, through a CDN link or a package installed and compiled with the project's existing build tools.
Where does the backend language actually matter?
The backend language affects how the HTML gets built, not whether Bootstrap works with it. PHP frameworks like Laravel and plain WordPress themes commonly pair with Bootstrap for admin panels and marketing sites. Python's Django and Flask, Ruby on Rails, and Java's Spring Framework all serve Bootstrap-styled templates through their own server-side rendering, and the output is standard HTML either way. Node.js sits slightly apart, since it's also the environment most JavaScript frontend frameworks build with; teams using React, Vue, or Angular alongside Bootstrap generally reach for a component wrapper library built for that framework instead of loading Bootstrap's own JavaScript directly.
What's worth knowing before adding it to a project?
The main gotcha isn't the backend language. It's the Bootstrap version. Versions 3 and 4 depend on jQuery for their JavaScript components, while Bootstrap 5 rewrote those components in vanilla JavaScript and dropped the dependency entirely. A project's server-side language choice has no bearing on that; it comes down to which Bootstrap release the project was built on.
