Our product has a lot of power features and is built to handle very advanced forms.

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?

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.

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.

  • Ask HN: What Are You Working On? (February 2025)
    I'm still working on DocSpring [1], originally launched on Hacker News in October 2017 under the name "FormAPI." 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.

  • So you want to modify the text of a PDF by hand
    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.
