New Site Radar vs Exploding Topics

Disclosure: we build New Site Radar. Everything below about Exploding Topics 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 Products change; if something here is out of date, email hello@newsiteradar.com and we will fix it.

Exploding Topics offers internet-wide trend discovery covering markets, products and investment opportunities, alongside trending startups and products. New Site Radar focuses on a narrower subject: monthly rankings of AI tool websites registered in 2025 or later that are gaining traffic.

You need an API that sends trend data to your own tools and dashboards.

When New Site Radar is the better fit

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.
