Delulu9 vs Keywords Everywhere

Keywords Everywhere started as a popular browser extension and has since expanded into an MCP tool for Claude. Delulu9 was built API-first from day one. That difference in origin shapes how each tool works in practice.

Keywords Everywhere Background

Keywords Everywhere has been around for years as a Chrome/Firefox extension that shows search volume, CPC, and competition data directly in your browser. The MCP version brings that same data into Claude, adding intent analysis and backlink metrics.

Pricing ranges from free (limited) to $10-50/mo for the API.

How Delulu9 Compares

Delulu9 was designed for developers from the start. No browser extension, no GUI dashboard. Everything runs through REST API or MCP server, which means it fits naturally into terminal-based workflows with Claude Code.

The multi-source approach is different too. Delulu9 pulls from Google, Bing, and Reddit. Keywords Everywhere focuses primarily on Google and YouTube data. If Reddit keyword data matters to your SEO strategy, that’s a meaningful gap.

Quick Comparison

Which Is Right for You

If you live in the browser and want keyword data overlaid on your search results, Keywords Everywhere is hard to beat. It’s a great extension.

If you work primarily in Claude Code or terminal environments and want a Keywords Everywhere alternative built for developer workflows, Delulu9 is the cleaner fit. The Reddit data source and content templates make it particularly useful for SaaS founders doing content-driven growth.
