Comparison
Signalcrest vs Exploding Topics
Search-trend database vs. leading community signals
Exploding Topics is a solid trend database built on search and web-mention data. The catch: search data is lagging by definition — people search for things after they've heard of them. Signalcrest reads the communities where trends start (Hacker News, GitHub, Stack Overflow, npm, Hugging Face, Dev.to, Lobsters, Product Hunt, arXiv, crypto governance forums) and scores cross-source momentum, so you see movement before it shows up in search.
| Signalcrest | Exploding Topics | |
|---|---|---|
| Starting price | $0 free · $24/mo real-time | $39/mo (100 tracked trends) |
| Top plan | $99/mo incl. API (10k req/mo) | $249/mo, API not included |
| API pricing | From $19/mo (2k req) · included at $99/mo (10k req) | Add-on to the $249 plan; reported at $1,000/mo per 1,000 requests (not publicly listed) |
| Data sources | 10 developer & builder communities, every 30 min | Search trends + web mentions |
| Timing | Leading — where trends start | Lagging — after search volume moves |
| Context per signal | Plain-English "why it matters" on every signal | Charts; interpretation is on you |
| Billing | Monthly or annual, cancel anytime, renewal reminder before every charge | Monthly plans |
| Free tier | Yes — top 5 live signals + 1 niche + weekly digest | No free tier — 7-day free trial, then paid |

Where Exploding Topics wins
A far larger database (1.1M+ tracked topics), consumer and e-commerce trend coverage, trending-startups data, absolute search metrics, and trend reports on the top tier. If you're tracking consumer product categories rather than technology, it's a reasonable pick.
Where Signalcrest wins
Earlier detection (community signals lead search by days to weeks), cross-source anti-hype scoring, LLM context on every signal, a real free tier, and an API from $19/mo — included outright in the $99 plan — instead of a four-figure add-on. Built for developers, founders, and investors watching technology markets.
If your edge depends on being early to technology trends, search-trend data is already too late. Watch the leading edge instead.
