Exploding Topics
A curated trend-discovery product that combines algorithmic detection with analyst review, then adds trend databases, search-volume history, channel context, and forecasting.
Exploding Topics vs Google Trends
Google Trends is the direct lens on Google search interest. Exploding Topics packages emerging-topic discovery across a wider set of web signals. The right choice depends on whether you already know the topic you want to test or need help finding candidates.

Quick answer
Pick the workflow, not the longest feature list.
Use Google Trends when you want a free, direct read on known search terms. Use Exploding Topics when you want a prepared discovery workflow and forward-looking trend research. Use What's Happening only when source-level evidence and an explicit scoring trail matter more than current production coverage: its live data service is not connected yet.

At a glance
What each product is built to do.
This is a job-to-be-done comparison, not a claim that one product contains every feature of another.
Google Trends
A Google product for exploring relative search interest, comparing terms or topics, checking regional patterns, and seeing what is trending now.
What's Happening
An early-access, source-linked approach that is designed to cluster official Hacker News, GitHub, and Google Trends RSS observations, expose the source trail, and publish its 45/35/20 scoring method.
Feature comparison
Six axes that change the research decision.
Claims below are limited to first-party descriptions and the verified production state of What's Happening.
| Axis | Exploding Topics | Google Trends | What's Happening |
|---|---|---|---|
| Primary evidence | Searches, conversations, mentions, and other web data described by Exploding Topics. | Aggregated Google search interest. | Official Hacker News, GitHub, and Google Trends RSS observations by default. |
| Starting point | Browse a prepared trend database or search for a topic. | Enter a term or topic, or open Trending Now. | Inspect a scored trend cluster and its attached source trail. |
| Measurement | Absolute search volume, growth history, and product-defined trend labels. | Relative interest normalized on a 0–100 scale. | A published 0–100 score: velocity 45%, reach 35%, novelty 20%. |
| Geography | Market and trend research views described by the product. | Interest by country, region, and subregion where available. | Earliest country-tagged observation in a cluster, never a claim of invention or cause. |
| Evidence trail | Curated topic views with analysis and related signals. | Search-interest charts, related topics, and related queries. | Designed to retain links to the underlying observations and add a concise Why Layer. |
| Current readiness | Established product with free and Pro surfaces. | Working public Google product. | Public interface is live; production trend data and account access are unavailable. |

Our difference
The score keeps its receipts.
What's Happening is designed so a trend is not just a line moving up. The cluster retains the observations used to score it, the earliest usable country tag, and a short explanation of what changed.
That narrower evidence path is useful for technology research. It does not make the product a forecasting service, and it does not prove where an idea originated.

Current production limit
The public interface is available. The live trend journey is not.
Production has no connected trend data service or authentication configuration. Trend results, source trails, accounts, and chat therefore cannot complete their real loop. The product reports that state directly instead of presenting fixtures as live activity.
Best fit
Choose by the decision in front of you.
Exploding Topics
Choose Exploding Topics when you want the product to surface and organize emerging categories before you have a precise query.
Google Trends
Choose Google Trends when you already know the terms to compare and want to inspect relative Google search interest by time and place.
What's Happening
Follow What's Happening if you want individual source observations, country-attributed evidence, and a transparent breakout score in one inspection path. Treat it as an early-access method today, not a working replacement.
FAQ
The practical questions.
Is Exploding Topics the same as Google Trends?
No. Google Trends visualizes Google search interest. Exploding Topics describes a broader discovery process that scans web sources, applies machine learning, and uses analyst review to organize emerging topics.
Which is better for validating a topic I already know?
Google Trends is usually the more direct first check because you can compare known terms, time ranges, and regions. Exploding Topics adds a more guided research layer when you need related opportunities or forward-looking discovery.
Does What's Happening predict the next trend?
No. Its breakout score is a watch signal based on velocity, reach, and novelty. It is not a prediction or a guarantee that a topic will keep growing.
Can I use What's Happening as a live alternative today?
Not yet. The public pages are available, but the production data service and authentication are not connected. The interface fails closed instead of showing demo records as live data.
