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 |
| Free tier, no delay | Yes | No | No | No | No |
| Microsecond detection timestamps | Yes | No | No | No | No |
Why the Seoul endpoint matters
- Dispatching Korean events from Tokyo adds a Seoul → Tokyo hop. Every Upbit listing pays that round-trip before it reaches you.
- 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 dispatches on the shortest possible path — no Seoul-to-Tokyo 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 SpeedTrial tier with zero delay so you can verify our benchmarks honestly (plus a free FreeDelayed tier with the full feed at a 240 ms delay), stable JSON schema, ?cex= filter, production-grade reliability.
Trade-off: three exchanges today (Binance, Upbit, Bithumb) — more added based on subscriber demand.
NewListingsFeed Slower · no µs
Streams Binance, Upbit and Bithumb over a WebSocket with a Seoul endpoint — but slower than CryptoListing.ws on all three, with no microsecond timestamps and no free tier to benchmark.
Coin Listing Slower · no µs
WebSocket listing notifications with a Seoul endpoint, covering the Korean market — but slower than CryptoListing.ws, with no microsecond timestamps and no free tier to benchmark.
DataMaxi+ Slower · no µs
Broader crypto data platform (market data, on-chain signals) with a WebSocket listing feed covering Binance and the Korean exchanges — but gated behind Pro+, single-region (no Seoul endpoint), no microsecond timestamps, and slower (its listing feed typically lags several seconds).
CryptoPanic Pro Slower · no µs
Aggregated news feed (exchange announcements, social signals, editorial) with a paid WebSocket — aggregation-bound and slower, no free tier to benchmark, and not a purpose-built listing trigger.
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
SpeedTrial 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 SpeedTrial. 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. SpeedTrial is a free 1-week key, renewable on request, with zero added delay. Prefer the full feed for free? FreeDelayed gives you complete ticker and title with a 240 ms delay.
