Valfi Releases Open-Source Local SEO Toolkit
At Valfi, we are thrilled to announce our latest open-source tool: the Valfi Local SEO Toolkit. This powerful Chrome extension is specifically designed to automate and streamline technical SEO analysis and accessibility workflows—all running entirely locally on your machine.
Why a Local Solution?
Privacy and data protection are paramount to us. Unlike many other SEO extensions, the Valfi Local SEO Toolkit runs completely offline within your browser. Your page data is never sent to external APIs or third-party servers. Even the tool’s advanced AI features are processed entirely offline via your local LM Studio instance, ensuring 100% data privacy.
Key Features
The Local SEO Toolkit bundles critical reports into one convenient, downloadable .zip package. Its core capabilities include:
- Cleaned Source Code: The tool extracts only the most relevant SEO elements (headings, text, images, links, meta tags) while stripping out heavy CSS, inline scripts, and other unnecessary noise.
- Full Page Screenshot: Leveraging Chrome’s Debugger API, the extension captures a precise, full-page PNG screenshot of the current webpage, beyond just the viewport.
- Network Requests Logging: Record all network activity (resources, types, sizes, load times) and export it directly as a CSV for detailed performance analysis.
- JSON-LD Schema Extraction: Collects all structured data (
application/ld+json) found on the page into a clean JSON file. - AI-Powered ALT Text Generator: The extension scans the page for images missing ALT text and batch-generates SEO-optimized descriptions.
Requirements and the Best Use Case
While the extension is great for simple data extraction, it is at its absolute best when paired with its AI capabilities. Please note that using the automated ALT text generator requires you to have LM Studio installed and running a vision-supported language model (such as gemma-4-26b-a4b-it-mlx).
However, the ultimate use case for this tool is seamless collaboration with other AI platforms. You can extract the bundled data package from any webpage and feed it straight into your own favorite AI (like ChatGPT, Claude, or Gemini). Providing your AI with a perfectly structured and cleaned package of the site’s source code, images, and load times instantly turns it into a highly informed, page-specific SEO assistant tailored exactly to your workflow!
The Power of Open Source
We have released the Local SEO Toolkit as open-source software so that developers, SEO experts, and site administrators can freely utilize, adapt, and build upon it to suit their own needs. The tool natively supports a bilingual user interface in both English and Finnish.
