ScreenshotOne vs ScreenshotAPI vs CaptureKit Comparison

If you are here, it’s probably for one of two reasons.

You’re already using one of the popular screenshot APIs, and something feels off.
Or you’re trying to pick the right one before your budget or your sanity takes a hit.

There are a lot of options out there. With some being really good in terms of response & their pricing. Most of them have easy-to-understand documentation.

In this blog, you’ll get exactly what you came for. A clear comparison of three widely used screenshot APIs. I will also try to educate you on what really matters when you pick one.

I’m Josseline, founder of Web API Group and recently acquired CaptureKit. This is what I do every day. I build APIs. I test APIs. I acquire some, & maintain them.

I've already used and compared all three APIs covered here. Everything you’re about to read comes from hands-on testing.

We’ll compare them on the metrics that count. Rendering accuracy. Speed. Reliability. Handling dynamic pages. CAPTCHA behaviour. Output quality. Pricing. Docs.

Let’s get started.

ScreenshotOne vs ScreenshotAPI vs CaptureKit — Key Comparison

ScreenshotOne API

ScreenshotOne is a developer-focused screenshot service created by Dmytro, built with a clear goal of taking the pain out of rendering web pages at scale. 

It’s used by developers and companies who need screenshots to behave predictably in real production environments. 

I personally know the founder & have been following him for quite a long. The API is great for heavy demands, & is scalable for sure.

The product has grown steadily, handling millions of renders every month, with a strong emphasis on stability and long-term reliability rather than flashy additions.

The product positions itself as a general-purpose screenshot layer for teams that need consistent visual records of the web, especially at scale.

Continuing on this, here are some of the good things we do ⬇️

What it does well

Bulk and high-volume capture: Designed to handle thousands of screenshots per run without manual batching or throttling logic on your side.

Built-in Playground: A browser-based playground lets you test URLs, tweak parameters, and preview results instantly. This removes most trial-and-error before writing any code.

Clean renders by default: Automatic removal of cookie banners, ads, overlays, and pop-ups keeps outputs consistent across pages and regions.

• Production-grade error handling with clear status codes

Integrations and setup

• Simple REST API

• Native Playground for request building and debugging

Pricing snapshot

Effective CPM (cost per 1,000 screenshots):

• Pro: $2.9 CPM

• Ultimate:  $1.78 CPM

Rate limits:
CaptureKit does not enforce tight per-minute caps on standard plans. Through auto-scaling and queue-free execution, throughput scales with usage rather than hitting artificial request ceilings that makes CPM and speed work together instead of against each other.

Wrapping Up:

If you’ve read this far, we’ve covered what actually matters when choosing a screenshot API: pricing, CPM, rate limits, reliability, speed, and how well the API fits real production use.

ScreenshotOne and ScreenshotAPI.net are both solid products. They do what they promise, and for certain use cases, they can be the right choice. 

CaptureKit, on the other hand, offers the same level of scalability while removing tight per-minute request limits which makes it easier to scale without friction in all plans. If you want to see how it fits your workflow, you can try CaptureKit for free from here. 

And if you’re not a developer or you prefer no-code workflows we’ve put together practical tutorials showing exactly how to use CaptureKit in real setups:

• Integrate CaptureKit with Lovable screenshot tool

• Extract titles and descriptions from all pages

• Build a screenshot tool with CaptureKit and HeyBoss

• Take screenshots of all URLs of a domain

• Automate website summaries using n8n and CaptureKit

• How directories can use a screenshot API

You’ll find more tutorials, comparisons, and deep dives on the CaptureKit blog, covering both developer and no-code use cases.
