We provide a PDF filling and generation API:

  • Upload your PDF to our visual template editor to set up form fields and data types
  • Post JSON to fill out existing PDF forms with data
  • Generate editable PDF forms, or overlay static data on top of fields
  • Create HTML/CSS templates with Liquid fields, then post JSON to generate PDFs
  • Use our merge API to combine multiple PDFs into a single document

PDF generation doesn't need to be complicated or take weeks of engineering time. Use our battle-tested service to start filling out PDFs in minutes.

Micro Python features and specs

  • Lightweight
    MicroPython is designed to be a streamlined version of Python, optimized for microcontrollers and small embedded systems. It has a smaller footprint than full Python, making it ideal for constrained environments.
  • Python Compatibility
    MicroPython is largely compatible with standard Python (Python 3.x), which allows developers who are familiar with Python to easily adapt to MicroPython for embedded applications.
  • Real-Time Capabilities
    MicroPython supports real-time operating systems and can handle tasks that require precise timing, making it suitable for controlling hardware directly.
  • Active Community
    MicroPython has a growing community of developers and enthusiasts who contribute to its development, provide support, and share resources and libraries.
  • Cross-Platform Support
    MicroPython can run on a wide range of hardware platforms, including popular boards like ESP8266, ESP32, and Raspberry Pi Pico, offering flexibility for developers.

Possible disadvantages of Micro Python

  • Limited Library Support
    Not all Python libraries are available in MicroPython, and some may require re-implementation or adaptation to work within the constraints of microcontrollers.
  • Performance Constraints
    Due to its lightweight nature and the limited resources of typical target devices, MicroPython may not perform as well as standard Python in terms of speed and processing power.
  • Learning Curve for Hardware Interfacing
    Developers who are new to embedded systems may face a learning curve when it comes to hardware interfacing and understanding the limitations and capabilities of microcontrollers.
  • Memory Limitations
    Microcontrollers have significantly less memory than computers, which can limit the complexity of programs that can be run using MicroPython.
  • Fragmented Development Environment
    Compared to standard Python, the tools and IDE support for MicroPython can be less mature and more fragmented, which may make development more challenging.

DocSpring features and specs

  • Automated PDF Generation
    DocSpring allows users to automate the generation of PDFs by filling out templates with data. This can significantly reduce the time and effort needed to create documents.
  • API Integration
    DocSpring offers a robust API, which allows developers to integrate PDF generation into their own applications easily, enhancing productivity and workflow automation.
  • Flexible Templates
    The platform supports flexible and customizable templates, enabling businesses to maintain brand consistency while meeting specific document formatting requirements.
  • Secure Data Handling
    DocSpring is SOC 2 Type II compliant. We ensure data security through encryption and secure storage options, making it suitable for handling sensitive information.
  • Ease of Use
    The user interface is designed to be intuitive, making it easy for businesses to create and manage PDF templates without requiring extensive technical knowledge.

Questions & Answers

As answered by people managing Micro Python and DocSpring.

Which are the primary technologies used for building your product?

DocSpring's answer:

Ruby on Rails, React, AWS

What makes your product unique?

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.

Why should a person choose your product over its competitors?

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.

How would you describe the primary audience of your 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.

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.
