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

DocSpring's answer:

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

  • Self-Updating Screenshots
    Itโ€™s a popular automation target for mobile projects. App Stores require screenshots, but generating N images for NUMBER_OF_SCREEN_SIZES times NUMBER_OF_LOCALIZATIONS can be a chore. In the past I wrote my own scripts for that, today tools like Fastlane[1] help. I use Fastlane for my logic puzzle game Nonoverse[2], I like it a lot; you can see sample screenshots in the App Store page. I also automated App Preview... - Source: Hacker News / 3 months ago
  • Moving from GitHub Actions? Software binary management for any CI/CD pipeline
    For mobile teams using fastlane tooling for build automation, our fastlane plugin couldn't be simpler to install, and pass in the built .apk .aab. Or .ipa. This allows for another easy approach in integrating Buildstash for artifact management regardless of which CI/CD orchestration tooling you may be using. - Source: dev.to / 7 months ago
  • Replacing App Center with GitHub Actions
    Adjust the files below. This is where you may end up needing to modify things that affect your App Center build. Try to keep them to a mimimum so you can still use App Center for builds should anything not work as expected. Fastlane is a tool that helps with automating build and release processes for mobile apps. You can think of it as a toolbox of easy-to-use wrapper functions around gradle for Android, and... - Source: dev.to / over 1 year ago
  • Lessons Learned from Building Mobile Apps and Software for Startups
    Keeping a mobile app in a releasable state at all times can be tricky with app store submission cycles (Google Play reviews can take well over a week in some cases), but tools like Bitrise and Fastlane can automate much of the release process. - Source: dev.to / over 1 year ago
  • Why I'm sticking with clean architecture for my Flutter projects
    And it gives me a perfect mock data source for automated testing. I can also use it when automating screenshots for the app store and play store deployments thanks to fastlane. Those screenshots can be deployed safe in the knowledge that the app would look exactly the same with data from a real service. All because of clean. - Source: dev.to / over 1 year ago

  • 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.

    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.
