## See where Onto fits. _And where it doesn't._

Six vendors that read the web for AI agents, grouped by what they actually are: three real alternatives to Read, two that find pages first, one doing a different job. Every page says when to pick the other one. Onto also has Serve, for your own site; Act is next, and isn't built.

### Six vendors, and us.

Each homepage scored by the free scanner on 24 Sep 2026, ours included. The line on every bar is our 80.

VendorWhat it isAIO score

**Onto**`buildonto.dev`Read, Serve and Act — Act is next, not built. _−20 no JSON-LD_**80**

**Direct alternative** 3_The same job as Read: a URL in, clean Markdown out. Pick one._

[**Firecrawl**`firecrawl.dev`The closest match: search, scrape, map and crawl. It offers LLM-based JSON extraction and deeper crawls; Onto runs no model and scores any page for free. _−10 Markdown not via the SDK__−20 no JSON-LD_**70**Onto vs Firecrawl](/compare/firecrawl) [**context.dev**`context.dev`Scrape, crawl and map like Read, plus brand data (logos, colours, company details) that Onto doesn't touch. _−10 Markdown not via the SDK_**90**Onto vs context.dev](/compare/context-dev) [**Jina Reader**`jina.ai`Markdown from any URL, rendered in a headless browser, free to try without a key. Onto adds a 0–100 score and an SDK for your own site. _−25 no Markdown version__−10 page over 200 KB__−20 no JSON-LD__−5 images without alt_**40**Onto vs Jina Reader](/compare/jina-reader)

**Search first** 2_They find pages for a query, and extract them too. Their core runs before Onto's: they find, Onto reads and scores._

[**Exa**`exa.ai`A search API for agents that returns pages for a natural-language query, with their content. _−10 Markdown not via the SDK_**90**Onto vs Exa](/compare/exa) [**Tavily**`tavily.com`Real-time web search and extraction for agents, built around the query. _−10 Markdown not via the SDK_**90**Onto vs Tavily](/compare/tavily)

**Different job** 1_Adjacent, but built for something else._

[**ScrapingBee**`scrapingbee.com`A scraping API built for collection at volume: rotating proxies and headless browsers, with a Markdown scraper and AI extraction on top. _−10 Markdown not via the SDK_**90**Onto vs ScrapingBee](/compare/scrapingbee)

We lose 20 for no JSON-LD, the fault we penalise everyone else for. Four vendors lose 10 for serving their own Markdown rather than through the Onto SDK: that's our scorer's rule, and we pass it by using our own SDK. Run any of them through the [scanner](/scanner) yourself.
