As answered by people managing IPRoyal and DocSpring.
DocSpring's answer:
Ruby on Rails, React, AWS
DocSpring's answer:
DocSpring is built specifically for developers who need reliable, secure PDF generation in production. We combine PDF form filling and HTML-to-PDF in a single API, with a visual template editor, typed fields, and validation to catch issues early. Our product has a lot of power features and is built to handle very advanced forms. Our infrastructure is SOC 2 Type II compliant, battle-tested, privacy focused, and optimized for high-volume workloads, so you can ship PDF features quickly and then stop thinking about them.
DocSpring's answer:
DocSpring is designed for teams who need a powerful tool with all the features you need for complex forms and business logic. DocSpring supports structured JSON, typed fields, and array iterations, and many other advanced features, so your templates stay aligned with your real data model. You get powerful validation, a visual editor, strong observability, and an API that fits into modern engineering workflows, so you spend less time fighting PDFs and more time shipping product.
DocSpring's answer:
DocSpring is built for engineering and product teams who manage complex documents in production: things like financial applications, insurance forms, healthcare and legal documents, HR and payroll workflows, and government-style forms.
DocSpring's answer:
I used to work at a payroll company (Gusto). We had built a similar in-house tool for filling out tax forms. I then built the first version of DocSpring (formerly named FormAPI) while I was living in Thailand. I built it to automate the filling out of visa application and visa extension forms, but realized that it could also be used for tax forms, real estate contracts, and any other kind of fillable PDF form.
