It also only partially rendered a Nike product page and was fully blocked on Glassdoor. Based on these results, Spider looks better suited to fast indexing of simpler public pages than to clean, production-ready extraction from JavaScript-heavy or protected sites. ## Demo Recording [Video: Spider demo recording](https://d3epheqghktydj.cloudfront.net/spider-screen-recording-2026-06-17-at-2-34-04-am.mov) *Video — Source-report walkthrough of Spider’s playground and test flow.* ## Feature-by-Feature Breakdown ### Markdown extraction from static pages **Verdict:** Captures core page copy accurately, but does a weak job removing site boilerplate. Spider can scrape a public page and return rendered text/markdown-style output through its playground. This was tested on a recipe blog page for chocolate chip cookies, where Spider preserved the central recipe content and layout blocks but also pulled in large amounts of non-essential site text. **Input:** Recipe blog URL ``` A public recipe-blog page for chocolate chip cookies was scraped in Spider’s cloud playground to test noise reduction on a static but boilerplate-heavy page. ``` **Output:** Rendered scrape result ![Rendered scrape result](https://d3epheqghktydj.cloudfront.net/spider-spider-playground-sallys-baking-scrape.png) *Image: Rendered scrape result* **Bottom line:** Spider can pull the main content from a static page, but it does not reliably return clean markdown when the source page carries heavy navigation and boilerplate. ### JavaScript-rendered page scraping **Verdict:** Partially works on a JS-heavy product page, but misses important hydrated content. Spider’s Smart mode is intended to handle dynamically rendered pages without manual selector work. It was tested on a Nike Air Force 1 product page to see whether client-side product details would fully load before extraction. **Input:** Nike product page URL ``` A Nike Air Force 1 ’07 product page was scraped using Spider’s Smart configuration to test client-side JavaScript hydration on a modern e-commerce layout. ``` **Output:** Rendered scrape result ![Rendered scrape result](https://d3epheqghktydj.cloudfront.net/spider-spider-playground-nike-air-force-scrape.png) *Image: Rendered scrape result* **Bottom line:** Spider can capture some top-level product attributes from a JS-heavy page, but it missed vital transactional elements and did not fully render the page state. ### Protected-site access **Verdict:** Failed on a site with active anti-bot protection. Spider attempts to fetch public URLs through its native scraping infrastructure, including pages that may apply security checks. This was tested on a Glassdoor jobs page to see whether Spider could get past a standard anti-bot interstitial. **Input:** Glassdoor jobs URL ``` A public Glassdoor jobs/search page was scraped to test whether Spider could access a protected site and still return meaningful page content. ``` **Output:** Blocked result ![Blocked result](https://d3epheqghktydj.cloudfront.net/spider-spider-playground-glassdoor-humans-only.png) *Image: Blocked result* **Bottom line:** Spider was not able to bypass the target site’s protection and returned only the block/interstitial page. ### URL-to-Markdown extraction **Verdict:** It preserved the main recipe content accurately, but the returned markdown was heavily polluted by page chrome and secondary content. Spider can scrape a public webpage through its cloud playground and return markdown without manual selector setup. On a noisy recipe blog page, it kept the ingredients block and step-by-step directions accurate, but it also dumped header navigation, submenu links, dietary links, social sharing URLs, cookie choice notices, and user reviews into the same markdown output. **Input:** Recipe blog page ``` A static but noisy recipe blog page used to test whether Spider could strip boilerplate and return only the meaningful article content. ``` **Output:** Observed markdown result ``` Spider processed the URL zero-shot in its cloud scraper playground. The markdown kept the core ingredients section and recipe directions with good copy accuracy, but the output was highly unrefined: it included global header navigation links, submenu and dietary dropdown links, social channel sharing URLs, cookie choice notices, and user reviews alongside the main recipe content. ``` **Bottom line:** Spider can capture the main text from a static page, but it did not clean the page structure well enough for downstream use without extra post-processing. ### Smart rendering for dynamic pages **Verdict:** Spider's Smart mode did not reliably wait for client-side hydration to complete. Spider offers a Smart request mode intended to handle more complex pages. On a Nike single-page product page with asynchronously loaded content, it extracted structural product descriptions and basic marketing copy, but it missed the dynamically loaded size-selection module entirely and returned an empty layout node where sizing data should have appeared. **Input:** Nike SPA product page ``` A JavaScript-heavy Nike product page used to test whether Spider's Smart mode could wait for client-side hydration and capture transactional product data such as available sizes. ``` **Output:** Observed dynamic rendering result ``` Using Spider's Smart performance configuration, the tool extracted structural description content and basic marketing attributes cleanly. However, it failed to wait for the client-side JavaScript components to finish loading. The size selection dashboard was skipped entirely, leaving an empty node with zero available sizing attributes under the displayed $115 price area. ``` **Bottom line:** Spider handled some visible product copy, but it missed an important dynamic purchase element, which makes its Smart mode unreliable for JS-heavy ecommerce pages. ### Proxy-based access to protected sites **Verdict:** Spider failed completely on the protected target in this test. Spider relies on its own scraping infrastructure and proxies to reach target pages automatically. On a Glassdoor page protected by Cloudflare, the request was blocked before extraction began, and the returned text consisted only of CAPTCHA and security-warning language rather than page content. **Input:** Glassdoor page behind Cloudflare ``` A public Glassdoor target used to test whether Spider could get through standard anti-bot protections and return usable markdown. ``` **Output:** Observed anti-bot result ``` Spider was blocked at the network edge by the target site's firewall rules. Automation did not proceed past the initial handshake, and the output contained only multi-language CAPTCHA strings and security warnings, including an explicit Cloudflare challenge and Ray ID rather than any usable page payload. ``` **Bottom line:** Spider's native proxies did not mask the scraper successfully enough to reach this Cloudflare-protected page. ## Usage-based pricing The source report describes Spider as pay-as-you-go rather than subscription-first. | Plan | Price | Notes | | --- | --- | --- | | Pay-As-You-Go ★ | Credits starting at $5 + usage billing | No monthly subscription, seat limits, or hidden fees. Bandwidth is $1 per GB, compute is $0.001 per minute, the reported average cost is roughly $0.03 per 1,000 pages, and failed requests cost nothing. | | AI Studio (Alpha) | Starting at $6/month | Optional add-on for natural-language crawling and structured JSON extraction without CSS selectors. Mentioned in pricing, but not hands-on tested in this report. | *Pricing was taken from the researcher’s report and was not independently validated with a billing artifact in this task.* ## Is This Right For You? A side-by-side guide based on our hands-on testing. **✓ Use This If** - You mainly need quick scraping of static or lightly dynamic public pages and can tolerate cleanup afterward. - You want a pay-as-you-go cost model instead of a recurring subscription. - You care more about fast broad indexing than about perfectly cleaned markdown from every page. **✕ Skip This If** - You need markdown that automatically strips almost all nav, cookie, and site-wide boilerplate. - You scrape JS-heavy e-commerce pages where variant selectors or other critical elements load client-side. - You rely on access to sites with strong anti-bot protection, as Spider was blocked outright on Glassdoor. ## Use case track record How Spider performed in this research scenario | Rank | Use Case | Notes | | --- | --- | --- | | Mixed | Extract clean markdown from public web pages using AI | Spider preserved core content on a static recipe page, but it returned heavy boilerplate, missed dynamic size data on a Nike SPA, and failed completely on a Cloudflare-protected Glassdoor page. | ## Classification - **Type:** text ## Frequently Asked Questions **Q: How well did Spider clean boilerplate from a recipe or blog page?** On the recipe-page test, Spider preserved the main recipe content accurately, but the output also included heavy boilerplate such as navigation links, cookie-preference text, and other non-essential site copy. The result was usable as raw extraction, but not clean enough to count as high-quality markdown without post-processing. **Q: Can Spider scrape JavaScript-heavy e-commerce pages?** Partially. On the Nike Air Force 1 product page, Spider captured the product name, category, and price, but it did not wait for all client-side components to finish loading. Important interactive content, including the size-selection area, was missing from the extracted result. **Q: Did Spider get past anti-bot protections in testing?** No. On a Glassdoor jobs page, Spider returned only a 'Humans only' security/interstitial page instead of the actual page content, so the scrape failed before any useful extraction happened. **Q: Was Spider tested for structured JSON extraction in this research?** No. The broader use case includes schema-driven structured extraction, and Spider’s pricing notes mention an AI Studio add-on for structured JSON extraction, but this hands-on report only tested page scraping behavior on three live URLs and did not validate JSON-schema extraction output. **Q: What output/export behavior was actually observed?** The report describes Spider as converting sites into pure HTML or markdown, and the hands-on tests were run through its playground interface with Rendered, JSON, and Code views visible. For the recipe-page test, export was noted as available through markdown viewport copies. **Q: How is Spider priced?** According to the report, Spider uses pay-as-you-go billing with credits starting at $5. It charges $1 per GB of bandwidth and $0.001 per minute of compute, with an estimated average of roughly $0.03 per 1,000 pages. Failed requests are reported as free, and an optional AI Studio alpha add-on starts at $6 per month. ## Similar Tools AI tools similar to Spider: - [Firecrawl](https://aidemos.com/tools/firecrawl) — Reliable on JavaScript-heavy and bot-protected pages, but its markdown output usually needs a cleanup step. - [Jina AI Reader](https://aidemos.com/tools/jina-ai-reader) — Turns public URLs into LLM-ready text, with the strongest tested results on static pages and weaker results on JS-heavy or protected sites. - [Skyvern](https://aidemos.com/tools/skyvern) — Visually navigates messy and JS-heavy pages to extract clean structured outputs, but it runs slower than text-first scrapers.
