    Developers might become overly reliant on generated data, which may not fully replicate the variability and unpredictability of real-world data inputs.
  • Learning Curve
    While the interface is user-friendly, new users may still face a learning curve when configuring advanced data generation settings.
  • Subscription Costs
    Some features of Generate Data may require a subscription, which could lead to additional costs for individuals or small teams with limited budgets.
  • Internet Dependence
    Being an online tool, Generate Data requires an internet connection to access, which might be a limitation in environments with restricted or intermittent connectivity.

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.

    Good morning, I should populate my db with fake data and I tried generatedata.com and mockaroo.com but they both have limits on the number of rows (500 and 1000 respectively).
