Cloudflare Radar 2.0: A Redesigned Window into Internet Traffic
Cloudflare launched Radar two years ago as a public window into the Internet trends, patterns and insights that the company uses internally to improve its service. The goal was simple: if you can’t see how the Internet is working, it’s hard to understand it or improve it. Since then, NGOs have used it to confirm on-the-ground disruption reports, journalists have tracked traffic shifts during geopolitical events, and analysts have studied new protocol adoptions.
Today, Cloudflare is releasing Radar 2.0 in beta, addressing three recurring pieces of user feedback: making insights easier to find, expanding the number and type of insights, and offering better ways to share data and charts.
A Redesigned Homepage for Quick Insights
The most visible change is the redesigned homepage, which now prioritizes glanceable data. Key improvements include:
- Prominent filtering. A top bar offers intuitive filtering by timeframe, country, and autonomous system (AS). A global search bar is on the way.
- Sidebar navigation. Users can jump straight to detailed sections on Traffic, Security & Attacks, Adoption & Usage, and Domains.
- Content cards. These display concise, timely "quick bytes"—small insights that link to deeper content on the same topic.
The homepage also supports direct search for a country, ASN, domain, or report, taking users to a dedicated page for that entity. For example, searching for google.com surfaces a domain-specific overview.
Within topic pages, quick bytes appear at the top for the active topic and on the right for related areas, letting users cross-navigate quickly. Detailed charts occupy the middle of the page. The sidebar also provides access to the Cloudflare Radar Outage Center, which is being covered in a separate announcement, and Radar Reports—interactive deep dives on subjects like DDoS attacks and the Meris Botnet.
New Sharing Options
Radar’s original sharing features were limited to snapshot downloads. Radar 2.0 introduces three significant additions:
- Social sharing. The new charts have a cleaner look, and soon users will be able to share them directly to social media platforms.
- Embeddable charts. Charts will act as widgets that can be embedded in web pages or blogs and will always display up-to-date data. This feature is expected later this year.
- Public API. Available today, the API allows developers to pull Radar data for custom analysis and visualization. For example, the last seven days of HTTP traffic data for Portugal can be fetched from
https://api.cloudflare.com/client/v4/radar/http/timeseries/device_type?dateRange=7d&location=PT. Access requires an API token or key.
Under the Hood: A New Tech Stack
Radar 2.0 runs on a completely rebuilt technology foundation. The site now uses GraphQL data endpoints and a public API, and is served via Cloudflare Pages and Workers with server-side rendering powered by Remix. The team adopted SVG for visualizations wherever practical, built a reusable data visualization component system, and uses Cosmos for visual test-driven development. These changes are intended to improve UX/UI and speed up future iteration as new topics—including email insights—are added over the coming months.
Users are encouraged to monitor radar.cloudflare.com for new content. Feedback can be submitted through the Cloudflare Community.
