CryptoListing.ws vs other WebSocket listing providers
CryptoListing.ws compared to NewListingsFeed, Coin Listing, DataMaxi+, and CryptoPanic Pro — what's actually different for a trading bot.
At-a-glance comparison
| Feature | CryptoListing.ws | NewListingsFeed | Coin Listing | DataMaxi+ | CryptoPanic Pro |
|---|---|---|---|---|---|
| Detection speed | Fastest | Slower | Slower | Slower | Slower |
| Seoul WebSocket server | Yes | No | No | No | No |
| Free tier, no delay | Yes | No | No | No | No |
| Microsecond detection timestamps | Yes | No | No | No | No |
Why the Seoul endpoint matters
- Other providers run from Tokyo only. Korean events go Seoul → Tokyo → you. An unnecessary Seoul-to-Tokyo hop on every Upbit listing.
- CryptoListing.ws runs Tokyo + Seoul. Upbit events dispatch directly out of AWS Seoul (ap-northeast-2c) via wss://kr.cryptolisting.ws.
- Trading Upbit on a CEX outside Tokyo? (Bybit Singapore, OKX Hong Kong, Korean CEX) Our Seoul endpoint = shortest possible path. With others, you eat their detour.
- Optimized for ultra-fast execution. Pick the endpoint closest to your matching engine.
Per-provider details
CryptoListing.ws Fastest
The fastest WebSocket provider for crypto listing and delisting announcements. Two endpoints — Tokyo (Binance + Upbit + Bithumb) and Seoul (Upbit, Korean colocation) — focused on the three CEX whose listings produce the largest pumps.
Strengths: fastest detection on the market, Seoul + Tokyo endpoints, microsecond detection and dispatch timestamps, free tier with zero delay so you can verify our benchmarks honestly, stable JSON schema, ?cex= filter, production-grade reliability.
Trade-off: three exchanges today (Binance, Upbit, Bithumb) — more added based on subscriber demand.
NewListingsFeed Slower · Tokyo only
Upbit-only WebSocket feed. Slower than CryptoListing.ws and no Seoul endpoint, so every Korean event carries the Seoul-to-Tokyo round-trip.
Coin Listing Slower · Tokyo only
WebSocket listing notifications for centralized exchange announcements. Slower than CryptoListing.ws and no Seoul endpoint.
DataMaxi+ Slower · Tokyo only
Broader crypto data platform (market data, on-chain signals) with listing notifications as one product among others. Slower than CryptoListing.ws and no Seoul endpoint.
CryptoPanic Pro Slower · Tokyo only
Aggregated news feed combining exchange announcements, social signals, and editorial sources. Slower than CryptoListing.ws and no Seoul endpoint.
Why CryptoListing.ws is the right choice
Built end-to-end for one job: getting listing and delisting announcements to your bot faster than anyone else.
Fastest on the market
Every layer of the stack is optimized for detection-to-dispatch latency.
The CEX that move the market
Binance, Upbit, Bithumb — the three exchanges whose listings produce the biggest pumps.
Tokyo + Seoul endpoints
Korean events skip the Seoul-to-Tokyo detour every competitor adds.
Microsecond timestamps
Detection and dispatch timestamps on every event — precise, verifiable measurement.
Honest, verifiable benchmarks
Free tier ships the same dispatch path as Premium. Measure us yourself before paying a cent.
Production-grade reliability
Stable JSON schema, ?cex= filtering, battle-tested infrastructure.
When another provider may fit better
- Speed isn't your priority. You just want to be aware of new listings, not snipe them.
- You want broader exchange coverage (Bitget, KuCoin, Coinbase, Kraken, etc.) and the smaller pumps from those venues are what interest you, not the Binance / Upbit / Bithumb moves.
Frequently asked questions
Does CryptoListing.ws really have a Seoul-native endpoint?
Yes. wss://kr.cryptolisting.ws runs on AWS Seoul (ap-northeast-2c, availability zone apne2-az3). The same API key authenticates on both endpoints. Rate limits and connection caps are tracked independently per server.
I trade Upbit listings on Bybit (Singapore) — does the Seoul endpoint help me?
Yes. Your bot still needs to reach Korea for the announcement to arrive, but the Seoul endpoint avoids the unnecessary Seoul-to-Tokyo hop that other providers add. Once the event is dispatched out of Seoul, your bot's connection from Singapore is the shortest possible path.
Can I use both endpoints at once?
Yes. Open one WebSocket to wss://cryptolisting.ws (Tokyo, full feed filtered to ?cex=binance,bithumb to avoid Upbit duplicates) and a second WebSocket to wss://kr.cryptolisting.ws (Seoul, Upbit only). Same API key on both. Connection caps apply independently per server.
How do I get reliable benchmark numbers?
Use the free tier. Each event carries microsecond-precision detectedTimestampUs and dispatchTimestampUs fields, so you can compute detection-to-dispatch yourself and compare it to any other provider on identical events. The free tier renews indefinitely with zero delay.
Benchmark us against your current provider
Run our feed alongside your current provider and compare detection-to-dispatch on identical events. Renew the free key as many times as you need — we want you to verify our claims before paying.
