Docassemble vs DocPayload

Docassemble is a free, open-source platform for guided interviews and document assembly. An interview can produce downloadable or emailed PDF, RTF or DOCX files, submit applications, interact with APIs or provide information. Authors build interviews with YAML, Markdown and Python logic, and can make questions depend on what information is still needed. Templates can use DOCX or PDF files, with a Word add-in for DOCX workflows. Other listed capabilities include touchscreen signatures, chat, screen sharing, remote screen control, AI, SMS, email, fax, OCR, multilingual interviews and multiuser applications. Developers can extend interviews with Python and connect third-party applications through the API. Deployment options include Docker, Docker Compose, Helm and installation without Docker; the maker recommends Docker. The software has no usage fees, but an internet-hosted server typically costs $10–$40 per month or more. Interview answers are encrypted in the SQL database unless multi_user is True; uploaded and assembled documents are not encrypted.

DocPayload generates PDF and DOCX documents from a JSON definition, with SVG also available as an API output. Inputs can include JSON payloads, stored templates, data objects, arrays, and data files. Listed document features include barcodes, AcroForm fields, watermarks, vector charts, signatures, and encryption. Its API uses standard HTTP requests, so an application that can POST JSON can connect without a language-specific SDK. Documents can be returned synchronously, emailed, or sent to an endpoint through webhooks with signed payloads and retries. DocPayload supports more than 100 scripts, including CJK, Devanagari, Thai, Arabic, and Hebrew. Deployment options include web and API access, self-hosting, VPC, and regional deployments in the US, EU, Canada, and UAE; the company says data stays in the chosen region. Starter is free and limited to up to five documents. Pay-as-you-go is billed at $0.50 page, and Enterprise costs $79 a month.
