Part 01 · Overview
Welcome
What it is, who it suits, its grades and the ten things to know first
2.4
GPA, above 41 of the 83 other technical SEO tools we grade
Headless-Render-API runs headless Chrome to pre-render JavaScript apps built with React, Angular, Vue and similar frameworks, so search engines and link-preview bots receive finished HTML. The same API takes screenshots, prints pages to PDF and scrapes pages. It has run since 2016, was called Prerender.cloud until 2022, and bills by the number of API requests in a month.
To get you started, here are 9 things to know about Headless-Render-API, taken from its own pages and our grades.
It's an API: you add a Node.js middleware, a proxy rule or its Docker server, with no dashboard to click through.
- 1
Best for pre-rendering billed by the API request
Headless-Render-API runs headless Chrome to hand bots rendered HTML from React, Angular or Vue apps, and the same API takes screenshots, prints PDFs and scrapes pages.
- 2
Paid plans start at $9 a month
As its pricing page puts it: $9 per month for under 20,000 requests, billed after use.
- 3
There is a free plan
Up to 500 API requests a month; requests made without an API token are also limited to 15 an hour.
- 4
It runs on Web
Web.
- 5
Pre-rendering for single-page apps
Proxy all requests, or only bots such as Googlebot and Twitterbot, through headless Chrome and get rendered HTML back for SEO and link previews.
- 6
Waits for data and keeps state
Rendering waits for XHR and WebSocket calls to finish, caches AJAX responses and can serialize app state into the HTML for the browser to pick up.
- 7
Screenshot API
Capture pages as PNG, WebP or JPEG, with options for device size, mobile viewport, high-DPI scale and cropping to an element.
- 8
A 2.4 GPA, above 41 of 83
That is against the other technical SEO tools we grade, on value, the free plan, features, ease of use and platforms.

The report card
Best for pre-rendering billed by the API request
Headless-Render-API runs headless Chrome to hand bots rendered HTML from React, Angular or Vue apps, and the same API takes screenshots, prints PDFs and scrapes pages. It's $9 a month under 20,000 requests, but going one past that makes it $40, there's no dashboard of reports, and setup means a middleware or proxy rule on your server.
| Subject | Grade | Comment |
|---|---|---|
| Value for money | A | $9 a month for under 20,000 requests, billed after use, right at 60% of this category's cheaper quarter and under a sixth of Prerender.io's $59 starting plan. Under 100,000 requests is $40. |
| Free plan and trial | C | Free under 500 API requests a month, and requests without a token are capped at 15 an hour. That's a cap a live site will hit. |
| Features | C | Pre-rendering that waits for XHR and WebSocket calls and can carry app state, plus screenshot, PDF and scrape APIs. It does pre-rendering fully, but that's a smaller job, there's no reports dashboard, and some server integrations are only examples. |
| Ease of use | D | No rating on record. It's an API: you add a Node.js middleware, a proxy rule or its Docker server, with no dashboard to click through. |
| Platforms and integrations | B | A web API with middleware or guides for Node.js, Express, Docker, Next.js, CloudFront, S3, Fly.io and nginx. No desktop or phone app. |
An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.
Who Headless-Render-API is for
- Fits if you run a Node.js or Next.js app and can add a middleware yourself
- Works for developers who also need screenshots or PDFs of pages from the same API
Who it is not for
- Watch out: going one request past 20,000 in a cycle moves the bill from $9 to $40
- Not for you if you want reports, as it's an API with no dashboard
- Tight if you use nginx, Apache, Ruby, Golang or IIS, whose integrations are examples and less well kept
- Tight if you stay free, at 500 requests a month and 15 an hour without a token
- Skip it if you can't edit your server, as setup is a middleware or proxy rule
Good to know
Good for
- Developers adding server-side rendering to an existing single-page app
- Small sites that stay under 20,000 rendered requests a month
- Teams that also want screenshots, PDFs or scraping from one API
Worth knowing
- Billing is by API requests at the end of each 30-day cycle, so going just past 20,000 requests moves the bill from $9 to $40.
- Without billing details, use is capped at 500 requests a month.
- The nginx, Apache, Ruby, Golang and IIS integrations are offered as examples and are not as well maintained as the Node.js, Docker, Next.js and CloudFront ones.
- It is an API with no dashboard of reports; setup means adding middleware or a proxy rule to your server.
