In terms of free tools, ones like jsPDF that run client-side typically give inconsistent results. It's a better idea to use something server-side like Puppeteer, which gives more control over how it renders. The issue is running it in prod, since using Puppeteer requires browsers to interact with. You typically end up running Puppeteer in your front end, and a bunch of Chrome browsers chewing through a separate server. Browserless is there to provide the browsers for those free libraries to work with. Sure, you can manage them yourself, but it's a PITA.
