DocSpring is built specifically for developers who need reliable, secure PDF generation in production.

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your product?

What's the story behind your product?

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.

Who are some of the biggest customers of your product?

DocSpring's answer:

  • SaaS services serving customers in the real estate, insurance, finance, and legal industries, among many others.

  • Introducing fulgur: a blazing fast HTML-to-PDF engine in Rust โ€” no browser required
    I run Devin Review and CodeRabbit on every PR. PDF spec edge cases and CSS layout corner cases are exactly the kind of thing where having a second pair of eyes matters, and as a solo maintainer I don't have human reviewers. Both tools have caught real issues, especially around pagination edge cases. - Source: dev.to / 3 months ago

It's a PDF generation API with a template editor UI for setting up fields on PDF forms. It makes it easy to turn complex tax and immigration forms into simple type-safe APIs with strong validations.

    Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface. Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.
