# Checkbot review (2026): is the free plan enough? > Chrome extension that crawls a site for SEO, speed and security issues Checked Oct 23, 2026 ยท graded Oct 23, 2026 by ToolGPA. Checkbot is a Chrome extension that crawls a website from your own computer and tests its pages against more than 50 SEO, speed and security rules, such as broken links, duplicate titles, invalid HTML, redirect chains and missing security headers. The free version checks up to 100 URLs per crawl; the paid Professional plan raises that to 10,000 and adds localhost crawling and CSV and PDF exports. - **Category:** SEO Browser Extensions - **Made by:** Checkbot (Sean Wilson) (since 2018) - **Website:** https://www.checkbot.io - **Runs on:** Browser extension - **Who should skip it:** Tight if your site runs past 100 URLs, as the free plan stops there and shows ads. - **Facts last checked:** Oct 23, 2026 ## Pricing As of Oct 23, 2026, Checkbot has a free plan, and paid plans start at $10 per month, billed annually ($15 billed monthly). - **Pricing model:** Free plan - **Free plan:** Basic plan: 100 URLs per crawl, unlimited crawls and unlimited sites, with ads. - **Free trial:** None listed. | Plan | Price | What you get | | --- | --- | --- | | Basic | $0 | For small sites: 100 URLs per crawl, unlimited crawls and sites, ad supported. | | Professional | $10 per month, billed annually ($15 billed monthly) | One user on any number of devices: 10,000 URLs per crawl, no ads, localhost and password-protected crawls, PDF reports and CSV export. | Read from https://www.checkbot.io/ on Oct 23, 2026. Prices change, so confirm with Checkbot before buying. ## Ways to pay less - **Save 33% with yearly billing** (Annual discount): Checkbot's pricing section lists Professional at $120 a year ($10 a month) instead of $15 billed monthly, a 33% saving. Source: https://www.checkbot.io/ ## Key features - **Site-wide crawl:** Crawls hundreds of pages at once from a start URL and scores them against 50+ rules drawn from Google, Mozilla and W3C guidance. - **SEO checks:** Finds broken links, missing or long titles and descriptions, duplicate content, canonical problems, missing image alt text, temporary redirects and sitemap issues. - **Speed and security checks:** Flags redirect chains, unminified or render-blocking CSS and JavaScript and missing caching or compression, plus HTTPS, mixed content and security header gaps. - **Staging and localhost sites:** Crawling runs on your own machine, so the paid plan can test localhost, private-network and HTTP Auth password-protected sites. - **Crawl filters and quick rechecks:** Limit a crawl by subdomain, folder, depth, pattern or file type, and recrawl a single page to confirm a fix. - **PDF reports and CSV export:** The Professional plan exports problem lists to CSV in bulk and produces PDF summary reports for clients or teammates. ## Good for - Developers checking a site for broken links and bad markup before launch - Freelancers auditing small client sites without a desktop crawler - People new to SEO who want each problem explained ## Worth knowing - It runs only in Google Chrome; the FAQ says there is no Firefox or other browser version. - The free plan stops at 100 URLs per crawl and shows ads; localhost crawls and exports need Professional. - It does not execute JavaScript while crawling, so content added by scripts is not tested. - A subscription covers one person; new customers can get a full refund within 14 days. ## ToolGPA grades **GPA: 2.4 out of 4**, graded Oct 23, 2026. Checkbot crawls a site from your own Chrome and checks its pages against 50+ SEO, speed and security rules, such as broken links, duplicate titles and redirect chains. The free plan stops at 100 URLs per crawl and shows ads, Professional is $10 a month on yearly billing, and it doesn't run JavaScript, so anything a script adds to a page goes untested. - **Value for money: B.** Professional is $10 a month billed yearly ($120), or $15 month to month, for one person on any number of devices. That's right on this category's cheaper-quarter line, though 30 of its 35 tools cost nothing. - **Free plan and trial: C.** Basic is free with unlimited crawls and sites, but it stops at 100 URLs per crawl and shows ads. A small brochure site fits; most blogs and shops won't, and exports and localhost crawls need Professional. - **Features: C.** Site-wide crawls scored on 50+ SEO, speed and security rules, crawl filters, single-page rechecks and, on Professional, PDF and CSV reports. The gap the listing names: it doesn't execute JavaScript, so content added by scripts isn't tested. - **Ease of use: B.** No rating on record, but nothing to set up: type a start URL and the crawl runs in your browser, with a help note on each problem it flags. - **Platforms and integrations: C.** Chrome only, so computers only; the FAQ says there's no Firefox or other browser version. No integrations or API are listed. These are ToolGPA's own grades. Graded from this listing, whose facts were read from Checkbot's own pages and its Chrome Web Store listing on 23 October 2026.

The 2 things listed below take a company. That makes this kind of software worth paying for, not this one in particular: 31 of the 34 other SEO browser extensions grade higher. It costs $120 a year. - You could not: A crawler that checks every page of a site. - You could not: Speed tests run from real browsers on a schedule.
