ScreenshotOne alternatives

Free, self-hosted screenshot APIs with no API key required.

TL;DR: ScreenshotOne is a hosted SaaS screenshot API starting at $17/mo. Your requests go through their servers, costs scale with volume, and there is no self-hosting option. Openkova is a free, MIT-licensed alternative you deploy on your own infrastructure. No API key. No rate limits. No data leaving your servers.

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.

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.
