ScreenshotOne alternatives
Free, self-hosted screenshot APIs with no API key required.
What ScreenshotOne provides
ScreenshotOne is a managed REST API for taking screenshots of public URLs. You send a request with your API key and target URL; they handle headless Chromium, return a PNG or PDF, and charge per screenshot or per seat depending on the plan. Features include JavaScript injection, CSS overrides, cookie passing, custom headers, and full-page capture.
For teams that need reliable screenshots without managing infrastructure, ScreenshotOne solves the problem quickly. For teams with privacy requirements, high screenshot volume, or a need to capture internal URLs, the managed SaaS model is a poor fit.
Where ScreenshotOne falls short
- Cost at scale — plans run from $17/mo (Basic) to $259/mo (Scale), and per-screenshot costs accumulate in high-volume workflows such as CI pipelines, OG image generation, or agent-driven automation.
- Privacy— every URL you screenshot is sent to ScreenshotOne's servers. Internal tools, staging environments, and authenticated pages all pass through a third party.
- No self-hosting — ScreenshotOne cannot be run on your own infrastructure. If it changes pricing or goes down, your integration breaks.
- No HTML file upload — ScreenshotOne accepts HTML as an inline parameter but does not support multipart file uploads. Rendering a local template requires pre-reading and encoding it on the client.
- No URL crawling — ScreenshotOne screenshots one URL per request. Capturing a multi-page site requires one API call per page.
- Vendor lock-in — ScreenshotOne uses a proprietary authentication scheme and request format. Migrating away requires rewriting every integration.

Frequently asked questions
Is there a free alternative to ScreenshotOne?
Yes. Openkova is free and MIT-licensed with no usage limits. Puppeteer and Playwright are also free open-source Node.js libraries for headless Chromium automation.
Can Openkova replace ScreenshotOne?
For most use cases, yes. Openkova captures URLs, HTML snippets, and uploaded HTML files via a REST API. It also adds depth-based URL crawling and SSE progress streaming. The trade-off is you manage the server instead of paying for managed infrastructure.
Does ScreenshotOne support self-hosting?
No. ScreenshotOne is managed SaaS only. Openkova is the MIT-licensed alternative you can deploy on any Docker host, VPS, or PaaS platform such as Railway or Fly.io.
What does vendor lock-in mean with a SaaS screenshot API?
Your integration is tied to a proprietary API format and authentication scheme. If the service changes pricing or disappears, every integration breaks. With Openkova (MIT license), you own the software and can fork it if needed.
