Facts

Website: doppio.sh
Price: Free tier · from $16/mo
Free trial: No
Async workflows: Asynchronous renders can send webhook callbacks and support batch workflows.
Developer integrations: Doppio is a REST API and lists support for Node.js, Python, PHP, Ruby, Go, Java, C#/.NET, and cURL.
Intended users: Doppio describes itself as a replacement for self-hosted Puppeteer, wkhtmltopdf, and fragile PDF libraries for teams automating document generation.
Quota behavior: The pricing FAQ says extra Pro documents cost $0.0037 each, while renders on other plans pause at the monthly quota until the next billing cycle unless the customer upgrades.
Rendering: The PDF API supports CSS Paged Media and Paged.js, custom page sizes and margins, background graphics, custom fonts, emoji, and configurable wait strategies.
Render timeout: The default render timeout is 30 seconds; complex documents can use asynchronous rendering with extended timeouts.
Screenshots: The Screenshot API captures full-page or element-level PNGs with custom viewports, retina scaling, clip regions, and transparent backgrounds.
Security: Doppio states that it is GDPR compliant, EU hosted, HDS certified, and renders each document in a sandboxed Chromium instance destroyed after processing.
Storage integrations: Doppio supports presigned URL uploads to Amazon S3, Google Cloud Storage, DigitalOcean Spaces, and MinIO.
Support: The features page says live chat with the engineering team has an average response time under two hours.
Templates: Doppio provides a built-in HTML/CSS editor with live preview, data injection, version management, and PDF or PNG generation by template ID.
Temporary hosting: Synchronous responses can temporarily host rendered documents; the site says presigned URL upload can send the file to the customer's own bucket instead.
