Diffbot alternatives: 10 web scraping APIs compared for LLM-ready data

The short answer

Diffbot is a heavyweight web data platform: computer-vision extraction that structures pages with no per-site rules, plus a pre-built Knowledge Graph of more than 10 billion entities. It is genuinely powerful, and for web-wide entity intelligence nothing else comes close. The reason teams look for a Diffbot alternative is cost and fit: the first paid tier is $299 a month and credits are consumed fast, which is a lot to pay if all you need is clean page content for a RAG pipeline. ClawEngine returns LLM-ready markdown or typed JSON from a managed API at $39 a month, without the Knowledge Graph you are not using.

Diffbot is not really a scraping API, and that is the whole point. It is a web data platform built around two heavy assets: automatic extraction that uses computer vision and machine learning to classify a page and return structured JSON with no selectors to write, and a Knowledge Graph of more than 10 billion entities you can query instead of crawling. For enterprises doing market intelligence, sales enrichment or entity research across the whole web, that is a genuinely differentiated product, and no ordinary scraping tool competes with it.

The reason people search for a Diffbot alternative is rarely quality. It is cost and fit. The first paid tier is $299 a month, credits drain quickly once you touch the Knowledge Graph (25 credits per record) or use proxies, and most teams building a RAG pipeline or an agent do not need any of the entity machinery. They need clean, chunk-ready content from pages they already know. ClawEngine is the lighter managed alternative for exactly that job: one call crawls a public page, renders its JavaScript and returns clean markdown or typed JSON against a schema you define, starting at $39 a month. It works on public and permitted data only and respects robots.txt and site Terms of Service.

ClawEngine

Hobby $39, Startup $99, Scale $399, Enterprise custom

Where it wins. Crawl, JavaScript rendering and typed schema extraction happen in a single API call, and robots.txt plus site Terms of Service are respected by default.

What to watch. There is no free plan, so it is priced for teams running real pipelines rather than one-off experiments.

Firecrawl

Hobby $16, Standard $83 (100k credits), Growth $333, Scale $599

Where it wins. Excellent developer experience, a well-loved open-source project, and markdown output tuned for token efficiency.

What to watch. Credits do not roll over, and stealth mode bills 5 credits per page instead of 1, which changes the real cost on protected sites.

Bright Data

Web Scraper API billed per record, roughly $0.75 to $3 per 1,000 depending on product and tier, with pay-as-you-go and no monthly commitment

Where it wins. The largest proxy network in the category (150M+ residential IPs across 195 countries) and hundreds of prebuilt domain scrapers and ready-made datasets.

What to watch. It is a broad platform rather than a single LLM-ready endpoint, so output usually needs cleaning before you can embed it, and the pricing surface is complex.

Apify

Free tier with $5 credits, Starter $29, Scale $199, Business $999, plus per-Actor usage

Where it wins. A marketplace of thousands of prebuilt Actors, so common targets are already solved, plus a full automation and scheduling platform.

What to watch. Costs stack (platform plan plus per-Actor compute or per-result fees), and output is generic JSON rather than LLM-ready markdown.

ScrapingBee

Freelance $49, Startup $99, Business $249

Where it wins. Very easy to adopt, dependable rendering, and a Google Search API bundled into every tier.

What to watch. You mostly get HTML back, so the cleaning, chunking and structuring work for an LLM is still yours to do.

ScraperAPI

Hobby $49 (100k credits), Business $299 (3M credits), Enterprise $475 (14M credits)

Where it wins. Strong price per request at volume and a very simple drop-in proxy API.

What to watch. It is proxy infrastructure first, so an LLM pipeline still needs its own parsing, boilerplate stripping and schema layer.

ZenRows

Developer $69, Startup $129, Business $299

Where it wins. Focused on getting through Cloudflare, DataDome and PerimeterX where simpler fetchers fail.

What to watch. Protected requests consume far more credits than plain ones, so the effective price depends heavily on your targets.

Oxylabs

Web Scraper API: Micro $49, Starter $99, Business $999, Custom+ by quote. Proxies are priced separately, residential from $6/GB

Where it wins. Enterprise-grade unblocking, a large global proxy network, and dedicated parsers for major targets, plus a free Custom Parser for your own CSS or XPath rules.

What to watch. The headline result counts are best-case for a single cheap target: Oxylabs own FAQ notes the Micro plan's 98,000 results apply to Amazon, and spreading the same plan across mixed targets works out closer to 16,000 per target. Whole-site crawling means buying a second product.

Crawl4AI

Apache-2.0, no license cost. You pay for your own servers, proxies and engineering time

Where it wins. No vendor bill at all, full control, deep crawling with BFS, DFS and best-first strategies, and output already shaped for RAG ingestion. It is the most popular open-source crawler in the category, with roughly 72,000 GitHub stars.

What to watch. You own the ops: proxy rotation, browser fleet, retries, blocks and upgrades. Free software is not free infrastructure.

ScrapeGraphAI

Free 500 credits one-time, Starter $20 (10k credits), Growth $100 (100k), Pro $500 (750k), Enterprise custom. The Python library is MIT licensed and free to self-host.

Where it wins. The open-source library (MIT, 28.4k GitHub stars) is a genuine option rather than a demo, it plugs into OpenAI, Groq, Azure, Gemini or a local Ollama model, and the managed API starts at $20 a month, below our own floor.

What to watch. The managed API bills per credit and the rate depends on the endpoint (extract costs 5 credits, stealth adds 5, a crawl adds 2 on top of per-page scrape cost), so cost per page is harder to predict. Self-hosting means you supply the LLM key and pay model tokens on every page.

Why teams pick ClawEngine

One API that turns any website into clean, LLM-ready data

Priced for the job, not the platform

A RAG pipeline needs clean page content, not a $299 floor and a credit model built for entity intelligence. ClawEngine starts at $39 a month and includes rendering and extraction rather than metering them separately.

LLM-ready by default

One call returns clean markdown or typed JSON with boilerplate stripped, ready to chunk and embed, so there is no entity graph or classification layer to configure around a simple ingestion task.

Honest about the trade

If you need Diffbot's Knowledge Graph or rule-less extraction across thousands of unknown site layouts, keep Diffbot. ClawEngine wins when the job is clean content from specific sources at a lower cost, not web-wide entity data.

People also ask

Diffbot alternatives: the questions buyers ask

What is the best Diffbot alternative?

It depends on what you actually use Diffbot for. If you need clean page content or typed fields for a RAG pipeline or an agent, ClawEngine and Firecrawl are the closest fits at a far lower floor, both returning LLM-ready markdown or JSON from a managed call. If you specifically need web-wide entity data or a knowledge graph, no scraping API replaces that part of Diffbot, and the honest answer is to keep Diffbot for it.

How much does Diffbot cost?

Diffbot has a free tier of 10,000 credits, then Startup at $299 a month for 250,000 credits, Plus at $899 for 1 million, Professional at $3,999 for 5 million, and custom Enterprise pricing. Credits are consumed per call, and a Knowledge Graph record costs 25 credits while a data-center proxy request doubles the cost, so heavy use adds up faster than the headline credit count suggests.

Is Diffbot overkill for a RAG pipeline?

Often, yes. RAG ingestion mostly needs clean, chunk-ready text from known URLs, and Diffbot bundles that with an entity Knowledge Graph and computer-vision classification you do not use for embedding. You end up paying a $299 floor and a credit model built for entity intelligence to do a job a lighter crawl-render-extract API does at a fraction of the price. Diffbot earns its cost when you need the entity data, not when you just need the page.

What does Diffbot do that a normal scraping API cannot?

Two things. Its Knowledge Graph is a queryable database of more than 10 billion entities you can pull from instead of crawling at all, which no generic scraper offers. And its automatic extraction uses computer vision to classify and structure any page type with no rules to write, which is genuinely useful across many different, unknown site layouts. If those are core to your work, Diffbot is the right tool.

Does ClawEngine have a knowledge graph?

No, and it is not trying to. ClawEngine is a focused crawl, render and schema-extraction API that turns public pages into clean markdown or typed JSON for RAG and agents. If your project depends on a pre-built entity graph of the whole web, Diffbot is the better choice. If it depends on getting clean, structured content out of specific sites into your own pipeline, that is exactly what ClawEngine is built for.

Good questions

Diffbot vs ClawEngine, answered

It is if you use Diffbot to pull page content or structured fields for a RAG pipeline or an agent, because ClawEngine does that from a managed call at a $39 floor instead of $299. It is not a replacement for the Knowledge Graph or web-wide entity extraction, which are Diffbot's real differentiators. Match the tool to which half of Diffbot you actually rely on.
Because you are paying for more than a scraper. The price funds a computer-vision extraction engine and a continuously maintained Knowledge Graph of over 10 billion entities. That is expensive to build and run, and it is worth it if you use the entity data. If you only need clean content from pages you already know, you are paying for capability you never touch.
On entity intelligence and unknown-page extraction at scale. The Knowledge Graph lets you query facts about companies, people and products without crawling anything, and the automatic extraction structures page types you have never seen with no rules to write. For web-wide research and enrichment, Diffbot is the stronger product and we would not claim otherwise.
For the ingestion half, usually yes. If your pipeline calls Diffbot to fetch and structure content from specific URLs, ClawEngine returns the same kind of clean markdown or typed JSON, renders JavaScript, and respects robots.txt, at a lower cost. Keep Diffbot only for any part that queries the Knowledge Graph or classifies large volumes of unknown page types.

Turn any website into clean, LLM-ready data
