Each free ToolTrace tool answers a focused technical question and explains what was inspected.
Use the Tech Stack Detector to identify the CMS, JavaScript frameworks, analytics tools, CDN, hosting provider, web server, and other technologies powering a public website.
Results are categorized and include confidence levels with specific evidence for each detection. Use it for competitive research, lead qualification, vendor evaluation, or technical audits.
Use the Article and Text Extractor for a blog post, news story, guide, or documentation page when the title, byline, publication date, main body, and section outline matter.
The tool returns source text rather than an AI summary. Review the result against the original page before quoting, republishing, or using it as research evidence.
Use the Free Web Page Scraper when you need readable Markdown or plain text from a public page without copying navigation, scripts, and layout code by hand.
The free tool performs one static fetch and limits each output to 100,000 characters. Use the Web Scraping API when JavaScript rendering, additional fields, or repeatable automation is required.
Use the SEO Page Inspector to check the fetched status, title, description, canonical, H1, heading order, image alt coverage, viewport, robots directive, social metadata, JSON-LD presence, and extracted content length.
The weighted score summarizes only those supported checks. It does not measure rankings, authority, backlinks, search demand, Core Web Vitals, or sitewide duplication.
Use the Schema Markup Checker to find JSON-LD blocks, inspect declared types, and catch JSON syntax failures or missing top-level context and type fields.
This is a fast implementation check, not a promise of rich-result eligibility. Use the official Schema.org and Google tools for their respective validation rules.
Use the Free Link Extractor to separate internal and external destinations, review anchor text, and identify nofollow, sponsored, or user-generated links.
Filter the result in the browser, then export the current link set as CSV or JSON for a migration review, content audit, or research workflow.
Use the Meta Tag Checker when you need to review a page title, meta description, canonical URL, Open Graph values, Twitter Card values, or social preview image. It is useful before publishing a landing page, article, product page, or campaign link.
The report separates detected tags from missing fields and shows representative search and social previews. It does not predict rankings or guarantee that every platform will use the same snippet.
Use the XML Sitemap Checker when you need to validate sitemap files and inspect the live pages they contain. It discovers common sitemap locations, reads sitemap indexes, and reports redirects, errors, noindex directives, robots blocks, and canonical conflicts.
The free check clearly states how many URLs were discovered and how many were inspected. This prevents a sample from being mistaken for a complete crawl.
The ToolTrace MCP server exposes every ToolTrace endpoint to Claude, Cursor, VS Code and Codex, so an agent can run these checks itself.
Free tools are ideal for investigation and one-off quality checks. For release gates, scheduled audits, AI agents, or large URL lists, use the ToolTrace APIs. The API returns structured JSON with usage and rate-limit headers that applications can validate and store.
