# agent cache vs parallel web: docs extraction vs parallel scraping

> parallel web is a parallel scraping infrastructure. agent cache is a docs extraction product. different tools, different jobs. here's why they're not competitors.

parallel web is parallel web. it's infrastructure for scraping the web at high concurrency and large scale. designed for speed and volume.

agent cache turns documentation sites into agent-ready markdown.

people might list them as "competitors" in a broad sense. they're not. this article is short because the distinction is obvious once you get it.

## parallel web is built to fetch pages at volume

parallel web is a scraping engine optimized for parallel execution. it launches many browser instances simultaneously. crawls thousands of pages in parallel. returns raw data at high throughput.

it's designed for scenarios like:
- monitoring competitor prices across 10,000 pages
- scraping job listings from hundreds of sites
- building large training datasets from the web
- any task where volume and speed are the constraints

it's infrastructure. it gives you raw pages fast.

## agent cache spends its effort on docs structure

agent cache is not infrastructure. it's not built for scale. it's built for quality.

it does one thing: extract documentation sites with structure, navigation, and context intact. it handles framework-specific quirks. it outputs structured bundles with metadata and indexes.

it's slow by design. 8-12 workers. polite crawling. careful parsing. framework-specific extraction logic.

## fetching pages quickly vs organizing a docs site

parallel web is fast and shallow. agent cache is slow and deep.

parallel web: "give me 50,000 pages from this site, raw html, as fast as possible."

agent cache: "give me this documentation site, but understand which div is the sidebar, which is the content area, which are version tabs. strip the navigation but keep the breadcrumbs. organize by framework categories."

parallel web doesn't care about mintlify vs. docusaurus. agent cache cares deeply.

parallel web gives you raw material. agent cache gives you a finished product.

## parallel web fits a high-volume scraping pipeline

**scale.** if you need to scrape 100,000 pages across 500 sites, parallel web handles it. agent cache crawls one docs site at a time with 8-12 workers. not the same league.

**general-purpose scraping.** parallel web isn't opinionated. it handles any site. agent cache only makes sense for documentation sites.

**infrastructure flexibility.** parallel web is a platform. integrate it into your own system. run it at scale. agent cache is a product with a specific workflow.

## a docs bundle saves you the setup and cleanup

**documentation-specific quality.** agent cache knows docs sites. it handles navigation, versioning, tab structures, code blocks, inline code, api reference formatting. parallel web just scrapes html.

**structured output.** agent cache gives you `meta.yaml`, `_map.json`, `INDEX.md`, folder hierarchy. parallel web gives you pages.

**zero configuration.** parallel web needs setup, orchestration, post-processing. agent cache: paste url, get zip.

**free.** parallel web charges for compute and bandwidth at scale. agent cache is free.

## a scraping engine still needs post-processing

these aren't competitors. they're different tools for different jobs.

parallel web is for scraping. agent cache is for documentation.

if you build a massive web scraping platform, you might use parallel web under the hood as part of the pipeline. but for docs specifically, agent cache does more with less.

if you were building a general-purpose web data platform, you'd integrate parallel web (or something like it) for the scraping layer, then add your own post-processing, structuring, and cleaning on top. that's what agent cache is: the post-processing and structuring layer for docs.

## choose by the output: raw pages or organized docs

parallel web is a scraping tool. agent cache is a documentation tool.

if you need to extract data at massive scale from arbitrary websites, use parallel web.

if you need to extract a documentation site into clean, structured, agent-ready markdown, use agent cache.

evaluating them as "competitors" is like evaluating a cnc router against a 3d printer. both make things. totally different use cases.
