New Site Radar vs Semrush

Disclosure: we build New Site Radar. Everything below about Semrush comes from its public pages as we read them on October 2, 2026 (sources at the bottom). Products change; if something here is out of date, email hello@newsiteradar.com and we will fix it.

Semrush is an SEO and AI-search visibility platform, with a separate Traffic & Market toolkit for competitor traffic. New Site Radar has a narrower job: monthly rankings of AI tool websites registered in 2025 or later that are gaining traffic, with each traffic figure compared against a second source.

When Semrush is the better fit

You need keyword tracking and site monitoring for your own website (500 to 5,000 tracked keywords depending on plan).
You want SEO and AI-search visibility data for any website, including established ones.

When New Site Radar is the better fit

You want AI tool sites that launched recently and are starting to grow, before they are well known.
You want to know how far to trust each number: every figure is checked against a second source where one exists, and the evidence is on the site page (see the methodology).
You want to query the data from Claude Code, Cursor or Codex over MCP.

Try it: the growth rankings have a free monthly sample, and Pro shows the full board.
