OpenSEO vs Meelu: an open source SEO tool or an AI coworker for your whole marketing

The short answer

OpenSEO is an open source SEO tool, positioned as an alternative to Ahrefs and Semrush. It covers keyword research, domain overviews, backlinks, rank tracking, a site audit and AI visibility. It connects to Google Search Console. Its MCP server lets your own AI agent, such as Claude, Codex or ChatGPT, use that data. You can use the hosted version or self-host it for free.

Meelu is a web app with its own AI coworker. It runs in your browser; nothing to install. It crawls your site, reads your Search Console and Analytics data, and tells you what to fix and what to write next, with the evidence. SEO is one part of it. The same app checks AI search answers against your pages, writes pages for your site, and answers questions about your data with charts.

Pick OpenSEO if you already work in an AI agent like Claude Code and mainly need SEO data. Pick Meelu if you want one app that covers your marketing, with suggestions you approve.

Where OpenSEO is better

• Open source. MIT licensed, and you can self-host it for free.
• It works in the agent you already use. If you live in Claude Code or Codex, OpenSEO brings SEO data there.
• Low entry price. The $10 plan includes $10 of usage, and Search Console data does not use credits.
• Research on any domain, with traffic estimates and ranking keywords.

Where Meelu is better

• More than SEO. Content writing and data analytics are part of the same app.
• An agent built for this job. You do not need to set up MCP or write prompts. Each desk has ready tasks, and Meelu explains each finding with the pages and numbers behind it.
• AI search checks that explain the gap. Meelu shows which points of a question your page answers, and links that to your Google ranking.
• A crawl that sees what AI crawlers miss. Meelu can render your pages as Googlebot on desktop and mobile and flags content that only appears after JavaScript runs.
• Nothing changes without you. Meelu never edits your site or publishes a page. It posts a social reply only after you approve it, to a thread you picked.

Pricing

OpenSEO's hosted Base Plan is $10 a month and includes $10 of usage each month. Its pricing page estimates about $0.05 per keyword search, $0.08 per backlink check and $0.002 per AI prompt check. The free trial includes $0.50 of credits. Self-hosting is free, and you pay DataForSEO for the data.

Meelu has no subscription and no plan tiers. One website costs 0.5 credits a day (1 credit is 1 US dollar), so about $15 a month.

Crawling and importing Search Console and Analytics data are free. Your first website is free for the first day.
