DocSpring

In plain words

DocSpring is an API service that automates PDF generation and signing. Users submit JSON data to create filled PDFs from templates—whether fillable forms, scanned documents, or HTML/CSS designs. The platform offers shareable and embeddable forms with e-signature capabilities and audit trails, integrating with Python, Ruby, Java, Node, and other programming languages. It's designed for developers and businesses needing to programmatically generate, populate, and sign documents at scale.

  PDF API – Generate, convert, and modify PDF documents2022 · ▲204

  Hi HN, Arek here. We’re super excited to officially launch PSPDFKit API [1]. PSPDFKit API is a collection of HTTP APIs that enable you to convert, generate, and edit documents without running any service on your infrastructure. What differentiates our API from others is that you can chain together multiple “actions” as part of a single API request. For example, you can convert, OCR, watermark, edit, and flatten a document — all in one call. Available actions [2]: - PDF Generator - PDF Converter - Image Converter - OCR - Watermark - Merge - Split - Duplicate - Delete - Flatten Our…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
