About CompetitorBase
CompetitorBase is a competitor monitoring tool that re-checks competitors' websites, pricing, ads and marketing channels every day and emails companies when something changes. Key facts are on the company page.
What CompetitorBase does
Growth-channel report
For a competitor's domain, the agents check which acquisition channels it runs: ads, outbound, SEO, PR, backlinks, reviews, socials, the founder's own audience and online buzz. Each channel is marked active, faint signal or nothing found.
Daily monitoring
Each competitor is re-checked on a 24-hour cycle. The previous version of each page is kept, so a rewritten headline or a changed price shows up as a diff.
Email alerts
An AI judge reviews every detected change and emails only the ones a founder in that market would act on: price moves, new or dropped plans, a rewritten homepage pitch, new product pages, a channel switched on or off.

Frequently asked questions
How is it different from Google Alerts?
Google Alerts reports what other sites write about a competitor. CompetitorBase reads the competitor's own pages, such as the pricing table and homepage, and compares them with the previous day's version.
Do I get an email for every edit?
No. Each detected change goes to an AI judge, and only changes that pass are emailed. Rotated testimonials, new blog posts and footer edits are filed without an email.
How do I sign in?
With a link sent to your email. There is no password.
