# Headless browser for AI agents: pages read at $0.80 per 1,000

Compared on Nov 12, 2026. The page: https://specstream.ai/headless-browser-for-ai-agents

A hosted headless browser for AI agents costs $0.08 to $0.12 a browser hour on Steel, Hyperbrowser and Browserbase, on paid plans from $20 to $250 a month. An agent that opens a page to read it pays for every minute it stays open.

SpecStream is the live web data engine for teams and agents. The Extract API reads up to 20 pages at once and returns their main text as Markdown. A page that refuses a plain read goes to a real browser, at the same price.

Reading costs $0.80 per 1,000 pages, and a page with no text is not charged. New accounts get $10 of credit, no card: 12,500 pages. The Extract API scores 0.908 F1 on WCXB, the highest score on the test ([benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=headless-browser-for-ai-agents)).

## SpecStream and hosted headless browsers side by side

| | SpecStream | Browserbase | Steel | Hyperbrowser |
|---|---|---|---|---|
| What the agent calls | `read_pages` over MCP or `POST /v1/extract` with up to 20 URLs, and `search_web` or `GET /v1/web-search` to find them | A cloud browser it drives, plus a Search API and a Fetch API | A cloud browser session it drives, plus browser tools at `/scrape` | A cloud browser session it drives, plus a Fetch API billed per page |
| Reading one page | $0.80 per 1,000 pages. A page with no text is not charged | Fetch API: $1 per 1,000 calls on Developer, $0.50 on Startup, $4 per 1,000 with Extract | Browser tools (`/scrape`): $5 per 1,000 | Fetch: $0.001 a page, and $0.005 more a page for JSON output |
| A page that refuses a plain read | Read again as a browser would ask for it, then in a real browser, then from the site's own feed or its newest public archive capture, at the same page price | Browser time: 100 browser hours on Developer, then $0.12 an hour. 500 on Startup, then $0.10 | Browser hours: $0.10 on Launch, $0.08 on Scale | Browser time: $0.10 an hour, plus any proxy data used |
| Search the web | $5 per 1,000 searches of up to 10 results, $1 per 1,000 on the fast tier. 97.9 F-score on all 1,000 SimpleQA Verified questions | $5 per 1,000 searches by default, after the included calls | Rates listed on its pricing page: browser hours, proxy bandwidth, CAPTCHA solves at $3 per 1,000 on Launch and `/scrape` | $0.005 a query |
| To start | $10 of credit on sign-up, no card. Pay from a balance, and a top-up from $10 never expires | Free: 1 browser hour. Developer $20 a month, Startup $99 a month | Launch: $30 of credits, one time. Scale: $250 a month plus usage | 5,000 free credits, enough for 50 browser hours. Startup $30 a month, Scale $100 a month |
| Many pages at once | Up to 20 URLs a call, each with up to 30 seconds, all read at the same time | 25 concurrent browsers on Developer, 100 on Startup | 10 concurrent sessions on Launch, 100 on Scale | 25 concurrent sessions on Startup, 100 on Scale |
| How long one read can run | Up to 30 seconds a URL, with nothing to open or close | 15 minutes a session on the Free plan | 15 minutes a session on Launch, 1 hour on Scale, up to 24 hours on Enterprise | Billed by the hour of browser time while the session runs |

## Why agents read pages with SpecStream

### One call reads the page

Send the URLs and get the text. There is no session to start, keep alive or close, and no browser to pay for while the model thinks.

```
curl https://api.specstream.ai/v1/extract \
  -H "Authorization: Bearer $SPECSTREAM_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"urls": ["https://example.com/pricing", "https://example.com/changelog"], "format": "markdown"}'
```

From an agent, connect the MCP server at `https://api.specstream.ai/mcp` and call `read_pages` with `{"urls": [...]}`. The setup for each client is at [MCP](https://specstream.ai/docs/mcp?utm_source=alternatives&utm_campaign=headless-browser-for-ai-agents).

### A real browser when the page needs one, at the page price

Each URL is read plainly first. A page that refuses that read is tried again as a browser would ask for it, then in a real browser, then from the site's own feed, then from its newest public archive capture. Each result says where it was read from in `read_from`: `live`, `site` or `archive`, with `captured_at` for an archive copy. Every page read costs $0.0008, whichever way it was read.

### You pay for the text you get

A page that gives no text is not charged. Neither is a 404 page, a plain 403 or a bot check: the status says `not_found`, `blocked` or `failed`, and a bot check's page is never returned as text. At $0.80 per 1,000 pages, reading costs less than Browserbase's Fetch with Extract at $4 per 1,000, Steel's `/scrape` at $5 per 1,000 and Hyperbrowser's Fetch with JSON output at $6 per 1,000.

### Text a model can use

`text` holds the page's main text, without its menus, footers and ads, as Markdown with headings, lists and links kept, or as plain text. Each result also carries `title`, `published` and `modified` when the page states them, and `emails` with every address the page carries, also those only its markup shows. PDF, Word and Excel files are read the same way. The Extract API scores 0.908 F1 on WCXB, a test of how well an extractor keeps a page's main text and drops the rest ([benchmarks](https://specstream.ai/benchmarks?utm_source=alternatives&utm_campaign=headless-browser-for-ai-agents)).

### Search and structured rows on the same key

The agent finds the pages with the Search API, at $5 per 1,000 searches of up to 10 results or $1 per 1,000 on the fast tier, scored 97.9 on SimpleQA Verified and 64.0 item F1 on WideSearch. When it needs many records with the same facts, such as every company that meets a condition, Deep Search returns them as structured rows at 5¢, 15¢ or $1 a row, with a source URL and read time on every value. One key and one balance pay for all three.

### When a step has to click or sign in

A form, a sign in or a checkout stays in the browser your agent already runs, such as Playwright or Browser Use, on your own machine. SpecStream then does the searching and the reading, so the browser opens only the pages it has to act on. The [Browser Use guide](https://specstream.ai/docs/integrations/browser-use?utm_source=alternatives&utm_campaign=headless-browser-for-ai-agents) adds SpecStream search to a browser agent in one function.

## Other headless browsers for AI agents

### Browserless

Hosted browsers billed in units: a unit is up to 30 seconds of browser time per connection. Prototyping is $25 a month billed annually for 20,000 units, then $0.0020 a unit. On SpecStream a page read costs $0.0008 however long the site takes, up to 30 seconds.

### Playwright

A free, open-source framework under Apache 2.0 that drives Chromium, Firefox and WebKit with one API, run on your own machines. You keep the browsers, the addresses and the retries. SpecStream reads the pages your agent only has to read, with the browser on its side.

### Hyperbrowser Fetch

Hyperbrowser's Fetch API reads a page for $0.001, or $0.006 with JSON output. Its free account holds 5,000 credits. SpecStream reads a page for $0.0008 with the real browser included, and returns its main text with dates and emails as named fields.

## How to give your agent SpecStream for reading

1. Create a key on the [Search API screen](https://specstream.ai/workspace/search?utm_source=alternatives&utm_campaign=headless-browser-for-ai-agents) of the workspace. A key that reads pages needs the `finds:spend` scope. New accounts get $10 of credit, no card.

2. Replace the step that opens a browser to read a page with one call. In Python:

```
import os
import requests

reply = requests.post(
    "https://api.specstream.ai/v1/extract",
    headers={"Authorization": f"Bearer {os.environ['SPECSTREAM_API_KEY']}"},
    json={"urls": ["https://example.com/pricing"], "format": "markdown"},
    timeout=60,
).json()
for page in reply["data"]["results"]:
    print(page["status"], page["url"], page.get("title"))
    print((page.get("text") or "")[:500])
```

3. Or connect your agent to `https://api.specstream.ai/mcp` and let it call `search_web` and `read_pages` itself. Keep the browser for the steps that click.

## Frequently asked questions

### What is the best headless browser for AI agents?

For an agent that reads pages, SpecStream: $0.80 per 1,000 pages through the Extract API or the `read_pages` MCP tool, with a real browser used on SpecStream's side when a page refuses a plain read. It returns each page's main text as Markdown, with its dates and emails, and a page with no text costs nothing.

### How much does a hosted headless browser cost?

$0.08 to $0.12 a browser hour on the plans read on Nov 12, 2026: Steel $0.10 on Launch and $0.08 on Scale, Hyperbrowser $0.10, Browserbase $0.12 on Developer ($20 a month) and $0.10 on Startup ($99 a month). SpecStream bills per page read instead, $0.80 per 1,000.

### Does an AI agent need a headless browser to read JavaScript pages?

Not to read them. SpecStream's Extract API reads up to 20 URLs a call, and a page that refuses a plain read is read again in a real browser at the same $0.0008 a page. The agent needs its own browser only for steps that click, type or sign in.

### How many pages does $10 read?

12,500 pages at $0.80 per 1,000, and new SpecStream accounts get $10 of credit with no card. Pages that give no text, 404 pages and bot checks are not charged.

### Can my agent use SpecStream over MCP?

Yes, at `https://api.specstream.ai/mcp`. `search_web` searches the live web at $5 per 1,000 searches, and `read_pages` reads up to 20 URLs a call at $0.80 per 1,000 pages, from one balance.

### Is a self-run browser cheaper than a hosted one?

Playwright is free under Apache 2.0, and you pay for the machines, the addresses and the time to keep them working. SpecStream reads a page for $0.0008 with none of those to run.
