1. RankIQ
Our Verdict — Best Of The Best
Price: Starts at $49/month
RankIQ is an amazing SEO tool that is full of actionable insights you can take to rank higher. We think it’s the best because of its powerful AI-based SEO tools, its content optimizer, and inviting price tag.
The Best Part:
No more guessing. With the “title optimizer” report, you’ll know which keywords you have to use in your titles, in order to get more organic clicks.
The Worst Part:
Sold as a bundle. RankIQ no longer sells its tiers on their own. The only offer on the site is RankIQ bundled with Aided’s AI writing apps, so you pay for both even if you only want the keyword research.
Get RankIQ if you want the absolute best SEO tool.
I recommend you grab the RankIQ + Aided bundle for $49/month.
(starts at $49/month)

2. SEO Panel
Our Verdict — Best SEO Control Panel
Price: Free forever
SEO Panel is a comprehensive open source SEO tool for digital marketers and businesses. We think it offers the best SEO control panel because of its powerful keyword analysis resources, detailed website audits, and easy-to-use backlink management.
The Best Part:
A one-stop-shop for SEO. SEO Panel has got you covered with everything from keyword research to competitor analysis, making your life easier as you optimize your content.
The Worst Part:
Lacks premium support. Since it’s an open-source tool, SEO Panel doesn’t offer the same level of customer support as paid alternatives.
Get it if you want a cost-effective open-source alternative to pricey SEO tools, without compromising on features and capabilities.
I recommend you download SEO Panel and install it on your own server today.
(free forever)

3. SerpBear
Our Verdict — Best For Rank Tracking
Price: Free forever
SerpBear is an open source rank tracker that you host yourself. We think it’s the best for rank tracking because it follows unlimited domains and keywords on Google and emails you daily, weekly, or monthly updates on your positions.
The Best Part:
Unlimited keywords. Add as many domains and keywords as you like, because the app itself puts no cap on what you track.
The Worst Part:
You bring the scraper. SerpBear checks Google through a third-party scraping service or your own proxies, so you have to set one up, and unless you run your own proxies, that means paying for a scraping service.
Get it if you want a free, self-hosted rank tracker with no keyword limits and you don’t mind a little setup.
I recommend you deploy SerpBear with Docker and connect a pay-as-you-go scraper like Serper today.
(free forever)

Our Verdict — Best For Analysis And Reporting
Price: Free forever
SEOMacroscope is a tasty open source SEO tool for running thorough website audits. We think it’s the best for analysis and reporting because of its comprehensive website crawling capabilities, in-depth content analytics, and insightful SEO reporting.
The Best Part:
It detects broken links effortlessly. SEOMacroscope nabs both internal and external broken links on your website, so you can clean things up and boost user experience.
The Worst Part:
It may feel a bit dry. As an analysis-focused tool, SEOMacroscope doesn’t have all the bells and whistles offered by premium SEO tools.
Get it if you want a reliable open-source SEO tool that offers thorough analysis and reporting features for your website, including broken link detection.
I recommend you download SEOMacroscope today.
(free forever)

Our Verdict — Best For Laravel Users
Price: Free forever
SEOTools for Laravel is an open source package that handles the SEO basics inside Laravel and Lumen apps. We think it’s the best for Laravel users because it plugs straight into the framework and sets your meta tags, social tags, and structured data from your controllers.
The Best Part:
SEO tags from your code. Set titles, meta descriptions, Open Graph tags, and Twitter Cards with a few lines of PHP, right where you build the page.
The Worst Part:
Developers only. There is no dashboard and no reports, so you need to be comfortable writing Laravel code to use it.
Get it if you build sites in Laravel and want clean, consistent SEO tags on every page without writing them by hand.
I recommend you install SEOTools for Laravel with Composer today.
(free forever)
Best For
SEOTools for Laravel is best for Laravel and Lumen developers who want to manage on-page SEO tags from their app code.

Our Verdict — Best For On-Page SEO Optimization
Price: Free forever
Python SEO Analyzer is an open source crawler that checks your site’s structure and on-page SEO from the command line. We think it’s the best for on-page SEO optimization because it crawls your pages, counts the words on each one, and warns you about technical SEO issues in a single report.
The Best Part:
Built-in SEO warnings. It flags missing or badly sized title tags, missing meta descriptions, and missing Open Graph tags on every page it crawls, all in one report.
The Worst Part:
Made for smaller sites. Its own author says Python isn’t the best choice for crawling big websites and points heavy users to a faster tool.
Get it if you want a free, scriptable on-page SEO audit for a small or mid-sized website.
I recommend you install Python SEO Analyzer with pip and run it on your homepage today.
(free forever)
Best For
Python SEO Analyzer is best for developers and technical SEOs who want to audit on-page SEO from the command line or inside their own Python scripts.
Top Features
Full-site crawl. Point it at your homepage or your sitemap, and it follows the links to analyze the pages it finds.
Headings and tags. Switch on its extra options to analyze the headings and additional tags on each page, too.
Word counts. See how many words each page has, so you can spot thin content fast.
Reports your way. Export the results as JSON by default, or as an HTML report you can open in a browser.
Runs anywhere. Install it with pip, run the prebuilt Docker image, or import it as a library in your own Python code.

7. Advertools
Our Verdict — Best For Large-Scale SEO Crawls
Price: Free forever
Advertools is an open source Python package full of SEO and online marketing tools. We think it’s the best for large-scale SEO crawls because its crawler can stop and resume big jobs, and almost every result lands in a table you can analyze.
The Best Part:
A crawler you can customize. Its SEO crawler pulls titles, headings, body text, and status codes by default, and you can add any CSS or XPath selector on top.
The Worst Part:
You need some Python. Most of its power lives in code, so non-coders will lean on its separate no-code apps instead.
Get it if you like working with SEO data in Python and want to crawl, audit, and analyze websites at scale for free.
I recommend you install Advertools with pip and run your first crawl today.
(free forever)
Best For
Advertools is best for technical SEOs and data-minded marketers who want to analyze crawls, sitemaps, and log files in Python.
Top Features
Stop and resume big crawls. Set custom headers, user agents, and crawl limits, and save jobs so long crawls can pause and pick up where they left off.
