Free tool · Real TCP probes

Know which proxies actually work.

Check up to 100 proxies at once. See HTTP and SOCKS5 support, real response time, anonymity, location, and IP quality on the website you need to reach.

Auto tests HTTP and SOCKS5 on every proxy. If both answer, the result shows HTTP + SOCKS5.

Adds a column estimating the operating system and device type behind each exit IP (Windows, Linux, Android, router firmware …). Over a proxy this can only be inferred from network fingerprints, so every result is a guess with a confidence level.

Single IP or your own machine? Use the OS detection check.

Probes run from our server in batches of 25. We never store your proxies. Results stay only in this browser session.

How it works

Stop trusting proxy lists at face value

Latency, anonymity, geo, ASN and header leaks, the five things that decide whether a proxy is actually usable. Check them all in one real probe.

Step 1

Paste your list

Drop up to 100 host:port entries. HTTP, HTTPS or SOCKS5. One per line or comma-separated.

Step 2

Real parallel probes

We open a TCP connection and route an HTTP request through each proxy, measuring connect + first byte.

Step 3

Enriched results

Exit IP is resolved to ASN, ISP, country, region, city and reverse DNS, with anonymity verdict and leak list.

Real latency, not ping

TCP connect + end-to-end HTTP timing, the number that actually predicts your scrape throughput.

Anonymity verdict

Elite, Anonymous or Transparent. Derived from the headers the proxy actually leaks to the target.

Geo + ASN truth

Catches IPs that claim US but route through a known datacenter ASN in another country.

这个免费代理检测工具能做什么

Rainproxy 代理检测工具可以免费在线判断一个代理是否真的可用、有多快、又会暴露你多少信息。粘贴 host:port 或 host:port:user:pass 格式的列表,我们会为每个代理建立真实的 TCP 连接并通过它发送一次 HTTP 请求,测量完整往返耗时。无需账号、无需下载,也没有使用次数限制。

如何判断代理是否可用

每行粘贴一个代理后点击检测。只有请求完整通过代理返回,才会标记为可用;连接被拒绝、超时或协议错误都会标记为失效。由于我们发送的是真实请求而不是 ping,那些端口有响应却无法转发流量的代理同样会被判为失效——在把列表交给采集程序之前,这正是你需要知道的。

  • 支持格式:ip:port、ip:port:user:pass、user:pass@ip:port
  • 支持协议:HTTP、HTTPS、SOCKS5,也可让工具自动识别
  • 单次最多 100 个代理,并发分批检测

如何解读检测结果

每一行对应一次真实探测。延迟为 TCP 建连加首字节返回的时间,比 ICMP ping 更能预测实际采集吞吐。出口 IP 是目标网站真正看到的地址,并会解析出国家、地区、城市、ISP 与 ASN,因此可以识破那些号称某国住宅、实际却从其他国家机房网络出口的代理。

  • 高匿(Elite):不会有任何请求头暴露你在使用代理
  • 普通匿名(Anonymous):目标知道有代理,但看不到你的真实 IP
  • 透明(Transparent):真实 IP 被转发,对匿名毫无意义

用你自己的目标网站实测

代理再快、匿名度再高,也可能恰好被你关心的那个站点封禁。填写目标域名后,工具会通过每个代理向该站点发起请求并返回状态码。这样,结果就不再只是“是否存活”,而是“这批代理能否用于我的实际业务”,无论目标是搜索引擎、电商平台、球鞋站点还是社交平台。

什么时候该换更好的代理

免费或抓取来的代理大多是共享的,往往早已被标记,几小时内就会失效——检测结果通常会直接证明这一点。如果列表里大量结果是透明、机房 IP 或被封禁,那问题出在代理来源而不是你的代码。Rainproxy 提供住宅、移动、ISP、机房与 IPv6 代理,纯净可用,你也可以先用这个工具验证再决定是否购买。
