Which one is for you

Pick Mangools if

  • Fits if you're a blogger who mostly needs keyword ideas and difficulty scores
  • Works for local keyword research down to city level

Look elsewhere if

  • Skip it if you need daily rankings, as they update weekly below the Agency plan at $97.70
  • Not for you if you want technical site audits, which none of the five tools does
  • Tight if you research in bursts, since lookups are capped per 24 hours, 100 on Basic
  • Pricey if you pay monthly, at $61 for Basic against $37.70 billed yearly, with refunds only within 48 hours
  • Too light for teams on Basic, which has no extra seats; sub-users on higher plans share one set of limits

Pick OpenSEO if

  • Fits if you already do your SEO work through Claude, Codex or another AI agent
  • Works for developers who want to self-host or build on open-source SEO code

Look elsewhere if

  • Tight if you research a lot, as $10 of usage is about 200 keyword searches and more is bought as top-ups
  • Watch out: plan credits reset each billing cycle, and top-ups only work while you have an active subscription
  • Watch out: the hosted service adds a 28% fee on DataForSEO requests
  • Skip it if you want self-hosting to be free, as you still pay DataForSEO, with a $50 minimum top-up
  • Skip it if you need AI tracking beyond ChatGPT, Gemini and Google AI Overviews

How we grade them

2.0GPAMangoolsFair2.8GPAOpenSEOGood
Value for money
CBasic is $37.70 a month on yearly billing ($61 monthly), exactly this category's middle. That buys 100 keyword lookups a day, 200 tracked keywords and 500 AI prompts. Paying monthly costs a lot more, and refunds only run for 48 hours.
A$10 a month with $10 of usage included, under 60% of this category's cheaper quarter. The vendor's estimate is about $0.05 per keyword search and $0.08 per domain overview. Heavier use is bought as top-ups, with a 28% fee on DataForSEO requests.
Free plan and trial
CA free plan with no card: 5 keyword lookups every 24 hours, each showing 15 related keywords. Enough to see how it works, not enough to do research. There's no trial of the paid plans.
CSelf-hosting is free, but you pay DataForSEO for the data, with a $50 minimum top-up. The hosted trial gives $0.50 of credits with no card, about ten keyword searches.
Features
CKeyword research down to city level, SERP checks, rank tracking, backlinks from Majestic's index, domain metrics and AI answer tracking on every plan. The gaps: rankings update weekly except on Agency, and none of the five tools audits your site.
BKeyword research, domain and backlink research, rank tracking by location and device, site audits, AI answer tracking and an MCP server for agents, all on one plan. It covers the whole job, though AI tracking names only ChatGPT, Gemini and AI Overviews.
Ease of use
CNo rating on record. The tools are pitched at bloggers, but daily lookup caps and setting up rank tracking take some getting used to.
CNo rating on record. The web app and agents both run on usage credits you'll want to watch, and self-hosting means Docker or Cloudflare plus a DataForSEO key.
Platforms and integrations
CWeb plus a browser extension, with Looker Studio the one integration on the listing. No desktop or phone app.
BWeb only, connected to Search Console, DataForSEO, Claude, ChatGPT, Codex, Cursor and Gemini through its MCP server. No desktop or phone app.

How this page was made

  • The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
  • The grades are our own, from each tool’s review or report card. The GPA is their average.
  • Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
