Doppio is a production-oriented HTML to PDF API and Screenshot API. It is positioned as a single hosted API that can replace self-managed Puppeteer, wkhtmltopdf, or traditional PDF libraries. Users can submit a URL, base64 HTML, or a template ID to generate PDF or PNG output, with support for both synchronous responses and asynchronous batch processing.
Rendering is based on Chromium. The documentation explicitly supports Flexbox, CSS Grid, webfonts, JavaScript-heavy pages, background images, emoji, custom paper sizes, margins, and portrait/landscape orientation. On the screenshot side, it supports full-page screenshots, element-level capture, viewport sizing, device scale factor, crop regions, and transparent backgrounds. Its template features are fairly complete, including a built-in HTML/CSS editor, live preview, placeholder data injection, a Paged.js workflow, and template versioning, making it suitable for recurring document scenarios such as invoices, contracts, and reports.
Doppio is a REST API, with examples using a Bearer API Key. The supported tech stacks cover Node.js, Python, PHP, Ruby, Go, Java, C#/.NET, and cURL. For integrations, it supports uploads via presigned URLs to Amazon S3, GCS, DigitalOcean Spaces, and MinIO, and can be paired with Webhooks to notify users when rendering is complete. Rendering is performed inside isolated Chromium sandboxes; instances are destroyed after processing, and rendering logs are provided for troubleshooting.
The main content states that users can sign up for free, with no credit card required and no trial expiration. A comparison table mentions a free tier of 400 docs/mo, but paid plans, overage fees, and SLA details are not disclosed. Compliance is a clear selling point: Doppio is GDPR-compliant, hosted in Europe, HDS-certified, and states that document content is not retained after rendering.
The strengths are simple developer integration, strong support for modern CSS, no operations burden, and coverage of both templating and asynchronous batch workflows. The drawbacks are the lack of a self-hosted option, limited pricing details, and unclear official SDK status. It is a good fit for document automation teams in SaaS products, enterprise back offices, healthcare, or European compliance-driven scenarios. Access from China is not discussed in the main content, so teams should test API connectivity, latency, and payment methods before going live. If access is restricted, alternatives include self-hosting Playwright/Puppeteer or combining domestic cloud functions with object storage.
