Since launching in 2020, Cloudflare Radar has provided one-of-a-kind insight into Internet traffic on a global scale. The open data that Radar publishes from our global network is used by a variety of experts in different domains: human rights advocates, journalists, academic researchers, network operators, and more. Today, as part of Agents Week , Radar is beta-launching a new tool: Radar Researcher.
Now, if you want to answer a question with Radar’s data, you can just ask in plain language and get an answer back with real, interactive charts, all built on Cloudflare's developer platform. You no longer need to find the right page, choose the right filters, or read the API documentation to write a query. Why we built Radar Researcher Over the past six years, the Radar team has worked to provide clear, accessible, reliable data visualizations of complex datasets.
This is not without its challenges: our user base is vast and ranges from curious novices to technical network experts. Even so, we publish as much insight into the Internet as seen from our network as we can: DNS queries from our public resolver 1. 1.
- 1 , HTTP traffic from across our global network, network quality data collected from Cloudflare Speed Test , and so much more. We also believe in the power of open, public data, which is why everything you see in Radar’s data visualizations is available via our free API .
Every year we make more and more of the Internet visible. But as Radar has evolved, so has the technology for working with data. AI tools are lowering the barrier to expertise: you no longer need to know a dataset's structure or vocabulary to get useful answers from it.
Subject-matter experts become collaborators rather than gatekeepers. Radar has always wanted to do more for users who shouldn't need to master our entire catalog and its vocabulary to fully appreciate our insights. (See our recent blog post on how the Internet responded to the 2026 FIFA World Cup .)
We also know that many of our users are in a hurry. For example, a journalist writing about the latest Internet outage likely does not have the time to search through each page for the perfect graph to tell their story. This is why we built Radar Researcher.
Meet Radar Researcher Radar Researcher is built to make accessing data as easy as describing what you’re looking for. All information is provided via Radar’s API, which ensures that the underlying LLM relies on real data, and can answer your questions quickly and in the same format as you would articulate them to a human. It's available on every Radar page.
Open the Radar Researcher panel from the header, and it docks beside whatever you're looking at, so you can keep browsing while you chat. Here are some examples of how you can use it: Get an answer in plain language, with real charts : Ask a question and get the same interactive visualizations you see across Radar, plus a short explanation. Choose your depth : Pick a concise, direct answer or a fuller, multi-topic report.
Keep the analysis going : After each answer, it suggests useful follow-up questions. Pick up where you left off : Conversations are saved in a searchable history you can pin and revisit, and you can share any conversation with a link. (Shared links expire automatically after 30 days.)
Audit the reasoning : Check how the LLM interpreted your question, which datasets it looked up and queried, and how it worked through the results to reach its answer. Ask your way : Type, use voice input, or launch it straight from Radar's search bar. Turn any chart into a conversation Researcher doesn't only start from a blank prompt.
Anywhere you see a chart on Radar, an Explain with AI action opens the assistant with that exact visualization already in hand. Instead of asking you to describe what you're looking at, it captures the exact visualization you're viewing and starts the conversation there. As you can see below, Radar Researcher takes the visualization in context, then analyzes the data and responds with an explanation.
Under the hood, the assistant hands the model three things at once: a screenshot of the chart (a vision-capable model reads the image directly), the exact data behind it from Radar's API, and the parameters of your current view, including location, date range, and any filters you've applied. The screenshot enables Radar Researcher to see what you see. The raw data keeps every number it cites precise instead of estimated from pixels, and the filters mean the explanation is about your exact view, not a generic version of the chart.
Use Case No. 1: What’s Internet quality like in Portugal? Say you're curious how good the home Internet is in a given country.
You can just ask: Instead of manually calling the API, choosing parameters, or hunting through Radar's pages, Radar Researcher interprets the question and does the work for you. You can follow each step in the screenshot: it reads what you asked, queries Radar's Internet quality API, then analyzes the results and answers in plain language. And rather than a wall of numbers, it renders the same interactive charts you'd see on the Radar Internet Quality section.
From here you might ask a natural follow-up, like comparing Portugal to a neighbor, and Radar Researcher fetches fresh data for each one. It even suggests useful next steps of its own, such as how Portugal stacks up against Spain or the country's most common Internet outages. By letting you find what you're looking for in plain language, we hope applying Radar's data to your own analysis is easier than ever.
Use Case No. 2: Investigating an Internet disruption Radar Researcher is also built with technical experts in mind. If we know one thing about engineers, researchers, and network operators, it’s that automation is key to their workflows.
Looking at the same data with manual actions can be cumbersome and limiting: how do you ensure you're always looking at the most relevant data? Consider a real event.
