Browserless alternative

Browserless Alternative With One Render Call, Not a Browser to Script

Browserless rents you managed headless Chrome that you drive with your own Puppeteer or Playwright code, billed by browser-time. That is the right tool when you need to script arbitrary browser tasks. When the job is only turning HTML or a URL into a PDF, you are paying for a browser fleet and still writing and maintaining the automation yourself.

Short answer

The reason to want a Browserless alternative is how it bills and what it hands back. Browserless is a remote browser: you either drive it with Puppeteer or Playwright over a websocket, or call its one-shot /pdf REST endpoint with a URL or HTML and your own wait and print options. Either way you pay by browser-time, in units of up to 30 seconds of browser connection, so a slow page costs more than a fast one, and the call returns file bytes that your app stores and serves itself. SitePDF is a single render endpoint: one HTTP call with a URL or HTML in, a finished PDF out, billed per render whatever the page weighs, with an optional timestamped archive of what was rendered. If you genuinely need to script a browser (crawling, testing, multi-step flows), stay on Browserless; if you only need documents, an endpoint removes the code and the browser-time meter.

What it is	Browser as a service: managed headless Chrome you script yourself	A single HTML/URL to PDF render endpoint
You write and maintain	Either a Puppeteer or Playwright script, or one call to its /pdf REST endpoint with your own wait and print options, plus storage for the returned file	One HTTP call; the PDF comes back as a hosted link
Entry price	$25/mo billed annually or $35 month to month (20,000 units) after a free 1,000-unit tier	$49/mo for the in-browser converter, API from $49/mo ($24/mo billed yearly)
Free tier	1,000 units/mo, 2 concurrent browsers, no card	One free PDF in the in-browser converter, then $49/mo; no card to create an API account
How usage is counted	Units of browser time: 1 unit per 30 seconds of browser connection, so a slow page costs more	Per render, whatever it weighs or how long it takes

Browserless is an excellent product for its actual purpose: a remote browser you control. This comparison is only about the narrow case where all you want out of that browser is a PDF, and paying for browser-time plus owning the code is more than the job needs.

Where Browserless is the right call

If your work involves driving a browser (scraping sites that fight back, running end to end tests, automating multi step logins, taking screenshots at scale, or anything that needs the full Puppeteer or Playwright surface) Browserless is a genuinely good answer. It hands you a managed, scalable browser over a websocket so you skip the worst part of self hosting: keeping a headless Chrome fleet alive. The API surface is the browser itself, which means anything a browser can do, you can do. We are not going to pretend a single purpose render endpoint replaces that.

The free tier of 1,000 units a month is enough to prototype real automation before you pay. If you are choosing a browser platform for varied automation and PDF is only one of several jobs, Browserless is the rational pick and this page is not for you.

Browser-time billing means a slow page costs more

Browserless meters usage in units, and a unit is up to 30 seconds of browser connection time. That model is fair for scripted automation, where you control how long the browser stays open, but it has an awkward edge for PDF work: a page that loads slowly, waits on a heavy dashboard, or blocks on a laggy third party font burns more units than a fast one, for the exact same document. Your cost per PDF becomes a function of the source site's performance, which you often do not control.

SitePDF counts a render as one render. A 200 millisecond invoice and a 20 second report cost the same, because you are buying the document, not the seconds of browser time it took to make it. For a workload that is purely HTML or URL to PDF, per render pricing is easier to forecast and harder to be surprised by.

Browserless is not the only vendor billing this way, and the increments differ far more than the rates do. We put its 30 second unit next to Browserbase, Steel and Hyperbrowser, normalized to the same job, on our Browserbase pricing comparison.

For the plan by plan numbers, including the month to month prices the pricing page only shows after you switch the billing toggle, and what a PDF costs at 1,000 to 250,000 renders a month, see Browserless pricing per PDF.

What you still own on Browserless

A correction to an earlier version of this section, which said Browserless always means writing a Puppeteer or Playwright script. It does not: Browserless has a one-shot /pdf REST endpoint that takes a URL or raw HTML with print options and returns the PDF, re-checked in its documentation on 25 September 2026. What you still own is the rest of the job: choosing the wait condition, the printBackground flag people forget, the page format and margins, the retry when a render hangs, and storing, naming and serving every file it returns. Teams that need more than a single print step still write the script, and that code is theirs to keep current as the libraries change.

SitePDF removes both. The wait logic, the print settings, the retries and the browser are all behind one endpoint. You send a URL or HTML and get a PDF. If what you actually need is browser control, that is a downgrade; if what you need is a document, it is one less codebase to own. The tradeoff is covered from the self hosting side in our library versus API guide, and for the Puppeteer path specifically in the Puppeteer alternative page.

The record Browserless was never meant to keep

Because Browserless is a raw browser, provenance is your problem. If you need a dated snapshot of what a page said when you rendered it, for an invoice dispute, a compliance file, or an audit two years out, you build and run that storage yourself on top of the browser output. Most teams never get around to it, and then the record is not there when someone asks.

SitePDF treats the record as part of the render. Add archive=true and the page is stored as a timestamped snapshot under your account, retrievable by id, with retention you control and deletion on request. If keeping a dated copy is the real reason you are generating PDFs, that archiving page covers what to keep and for how long. Weigh the whole field, including the tools that beat us on price, in our seven tool comparison.

The SitePDF call, for comparison: no browser script, one request returns the PDF and the dated record.

curl https://api.sitepdf.com/v1/render \
  -H "Authorization: Bearer $SITEPDF_KEY" \
  -d url="https://app.example.com/reports/q2" \
  -d wait_for="#report-ready" \
  -d format=A4 \
  -d archive=true

Questions about this job

What is the difference between Browserless and an HTML to PDF API?

Browserless is a managed headless browser billed by browser time. You can drive it with Puppeteer or Playwright, or call its /pdf REST endpoint, and it returns the file for your app to store. An HTML to PDF API like SitePDF bills per render and returns a hosted PDF with an optional dated archive copy. Browserless is broader and better for scripted work; a render API is simpler to budget when the only job is documents.

How much does Browserless cost?

Browserless starts free with 1,000 units a month, then $25 a month for 20,000 units, $140 a month for 180,000 units and $350 a month for 500,000 units, billed annually, or $35, $200 and $500 month to month, with enterprise plans above that. A unit is up to 30 seconds of browser connection time, so slower pages cost more. Figures re-read from browserless.io on 25 September 2026.

Why does browser-time billing matter for PDFs?

Because the same document can cost different amounts depending on how long the page took to render. A slow loading dashboard or a laggy font server burns more units than a fast page for an identical PDF, so your cost per document tracks the source site's speed rather than the work you asked for. Per render pricing charges the same for both, which is easier to forecast for pure HTML to PDF workloads.

When should I stay on Browserless instead of switching?

Stay if you need real browser control: scraping, automated testing, multi step logins, screenshots, or any task beyond turning HTML into a PDF. Browserless gives you the full Puppeteer and Playwright surface, which a single purpose render endpoint does not. Switch only when PDF generation is the whole job and the automation code plus browser-time meter are more than that job needs.

What is the best Browserless alternative for PDF generation?

If you only need HTML or URL to PDF, a dedicated render API removes both the automation code and the browser-time billing. SitePDF does it per render with an optional timestamped archive; Api2Pdf and PDFShift are usage based options worth pricing too. If you need to keep scripting the browser, there is no PDF-only replacement, and Browserless remains the right tool.
