Free Proxy Checker
Test any HTTP, HTTPS, SOCKS4 or SOCKS5 proxy for liveness, speed, anonymity and exit country. Paste up to 100 proxies, results stream in live, with no signup and no API key.
| Proxy | Status | Latency | Protocol | Anonymity | Country |
|---|
Your proxies are checked in-session and never stored, logged or shared. The test runs on our network, so your own IP is never exposed to the proxies you check.
Built by a proxy network, not a scraper
Databay runs a production proxy network and re-verifies its own free proxy list every 5 minutes. This tool exposes those same probes, with one important difference from most free checkers.
Your IP stays hidden
The test runs on Databay's network, never in your browser. The proxies you check never see your real IP address, unlike checkers that connect straight from your machine.
Real probes, not port scans
Each proxy gets a genuine HTTP or SOCKS handshake and a live request to a neutral endpoint, so liveness, latency and anonymity are measured, not guessed.
Live streaming results
Results appear row by row as each proxy is tested, up to 100 at a time, with one-click copy and .txt export of the working ones.
Check your proxies in three steps
Paste your proxy list
Paste your proxies into the box, one per line, in ip:port format, for example 45.61.20.11:8080. You can check up to 100 at a time.
Choose a protocol
Select HTTP, HTTPS, SOCKS4 or SOCKS5, or leave it on Auto-detect and the checker identifies what each proxy speaks.
Run the check and export the winners
Press Check proxies. Live results stream into a sortable table, then copy or download the proxies that pass as a .txt file.
What each column means
The checker reports six signals for every proxy you submit. Here is how to read them.
Status
Alive means the proxy accepted a connection and relayed the test request. Dead means it refused, timed out, or failed to relay.
Latency
Round-trip time of the test request through the proxy, in milliseconds. Lower is better.
Protocol
The working protocol, confirmed with a real handshake: HTTP, HTTPS, SOCKS4 or SOCKS5. Auto-detect fills this in for you.
Anonymity
Elite hides your IP and leaks no proxy headers, Anonymous hides your IP but reveals a proxy is used, Transparent leaks your real IP.
Exit country
Where the proxy appears to browse from, resolved from the address our judge endpoint actually sees, when detectable.
Elite, anonymous and transparent explained
A proxy's anonymity level decides how much a target site can learn about you. It is the single most important signal for scraping and privacy.
| Level | Hides your real IP | Reveals proxy use | Best for |
|---|---|---|---|
| Elite (high-anonymous) | Yes | No | Scraping, automation, privacy |
| Anonymous | Yes | Yes (proxy header) | Casual browsing, geo-unblocking |
| Transparent | No | Yes | Caching and content filtering only |
HTTP, HTTPS, SOCKS4 and SOCKS5 compared
The checker tests all four. Which one you want depends on what you are connecting to.
| Feature | HTTP | HTTPS | SOCKS4 | SOCKS5 |
|---|---|---|---|---|
| Encrypts the connection | No | Yes (CONNECT tunnel) | No | No |
| Traffic it handles | HTTP web traffic | Any site over TLS | TCP only | TCP and UDP |
| Authentication | Basic | Basic | None | Username and password |
| Typical use | Web scraping, browsing | Secure sites | Legacy apps | Versatile, most modern tools |
Our proxy verification method
Every proxy you submit is routed through Databay's verification pipeline, the same system that re-checks our free proxy list every 5 minutes. The test never runs in your browser or on the website itself, so your own IP address is never exposed to the proxies you paste. For the same reason the checker never asks for your proxy credentials: a public proxy only needs its ip:port to be probed.
Each proxy gets a real protocol handshake for HTTP, HTTPS, SOCKS4 or SOCKS5, then a timed request to a neutral judge endpoint. We inspect the request headers the judge receives: if the proxy leaks your origin IP it is classed as transparent, if it forwards a Via or X-Forwarded-For header it is anonymous, and if it reveals nothing it is elite. Latency is the round-trip time of that request in milliseconds, and the exit country is resolved from the address the judge actually sees.
Because the probe is a genuine request and not a port scan, a proxy that answers a TCP connection but cannot actually relay traffic is correctly reported as dead.
How Databay's checker compares
Most free online proxy checkers connect straight from your browser, which exposes your own IP to every proxy you test. Ours does not.
| Databay proxy checker | Typical online checker | |
|---|---|---|
| Where the test runs | On our network, your IP is never exposed | From your own browser and IP |
| Test method | Real HTTP or SOCKS handshake and relayed request | Often a port scan or JS fetch |
| Protocols | HTTP, HTTPS, SOCKS4, SOCKS5 and auto-detect | Frequently HTTP only |
| Anonymity grading | Elite, anonymous or transparent, from header inspection | Rarely graded |
| Results | Server-rendered, stream live, export .txt and .csv | Often JS-only, no export |
| Access | Free, no signup, no API key | Varies, some require login |
When free proxies are not enough
Free and public proxies are great for testing and learning. For work that has to succeed, the difference is stark.
| Free / public proxies | Verified proxies (Databay) | |
|---|---|---|
| Uptime | Minutes to hours, churns constantly | 99.9%+ |
| Anonymity | Inconsistent, often transparent | Audited elite and anonymous pools |
| Speed | Highly variable | Consistent, low latency |
| Logging risk | Unknown operator, may log or inject | Ethically sourced, no injection |
| Best for | Testing, learning, one-off tasks | Production scraping and automation |
When to check your proxies
Any workflow that leans on proxies fails quietly when they die. Verify a list before these jobs, and again if success rates dip mid-run.
Web scraping
Confirm proxies are alive and elite before a crawl, so requests are not blocked or traced back to your own IP.
Ad verification
Check that geo-targeted proxies exit in the right country before you audit how ads render for local users.
Market research
Validate speed and uptime so price and catalog scrapes finish without gaps from dead endpoints.
SEO monitoring
Test exit country and anonymity before pulling localized SERPs, so rankings reflect the right region.
Ecommerce and retail
Filter a list down to fast, working proxies before checkout automation or stock monitoring runs.
Social media management
Weed out transparent or dead proxies before assigning them to accounts, to avoid leaks and bans.
