In their own words
Anvil PDF Generation API
Anvil PDF Generation API creates PDFs on demand from HTML and CSS or Markdown. For HTML, it supports full CSS, custom TTF fonts, page dimensions and margins, headers and footers, page numbers, and fillable forms. Markdown conversion applies a default theme, and callers can provide CSS of their own. The API can also generate variable-length documents and merge data into PDFs. Anvil lists SDKs for C#/.NET, JavaScript, Python, and TypeScript; Go, Java, PHP, and Ruby are marked as coming soon. A Zapier integration can automate paperwork workflows, including filling a PDF or starting or pre-filling a Workflow. It is a cloud service with API and web access, email support, and listed SOC 2 and HIPAA compliance. Test mode is free and unlimited on every plan, though test documents are watermarked and use demo signatures. API PDF fill or generation costs $0.10 per use; enabling metered usage with a valid credit card provides 2,500 starter credits. The Free plan is free and UI-only; API key access requires a credit card or upgrade. Custom fonts must be TTF; OTF and WOFF are not supported.
Docmosis
Docmosis generates documents from Microsoft Word or LibreOffice Writer templates, producing PDF, DOCX, ODT, or TXT files. Templates can combine placeholders, text, images, tables, conditional content, calculations, repeating data, formatting, page numbering, and tables of contents. Its API-first engine connects to custom applications and third-party platforms, with official integrations for Java, C#/.NET, PHP, Python, Ruby, Bubble, Appian, Mendix, Zapier, and OutSystems. Buyers can use the AWS-hosted Cloud service, the self-hosted Tornado engine for Linux, Windows, or Docker, or Docmosis-Java, a library for Java applications. Cloud hosting spans multiple geographic regions and scales under load. Cloud input and generated documents are deleted after processing; templates are encrypted at rest and HTTPS is enforced. Cloud plans start at $49 a month, billed monthly, and a 30-day trial is available without a credit card. Self-hosted options require customers to install, configure, run, and manually update the software. Docmosis says it achieved SOC 2 Type II in 2025 and supports the Australian Privacy Act, GDPR, and data-processing agreements.
