About
About these free Bulgaria SOCKS4 proxies
These are public proxies gathered from across the web and re-verified continuously by HProxy's engine. They are free, and they are fine for quick, low-stakes tasks. Like all public proxies they are shared and they go down without warning. Most of them are already blocked by the big sites. Always test one before you rely on it.

The long read
About free Bulgaria SOCKS4 proxies.
The list above holds every free SOCKS4 proxy in Bulgaria that answered our checker recently. At 16:51 UTC on 15 September 2026, 9 SOCKS4 entries in Bulgaria were alive.
That is 50.0 percent of the 18 live entries in Bulgaria at the same moment. SOCKS4 was the most common protocol in the country, ahead of HTTP with 8 live entries. Among the 72 countries with live SOCKS4 entries, Bulgaria held the 12th largest number.
9 live entries are too few for a fair success rate, so this page reports counts.
All 9 live entries were flagged for recent abuse, and none sat on datacenter space. For work that has to keep running, paid Bulgaria proxies are built for it.

What a free Bulgaria SOCKS4 proxy can reach
On 15 September 2026 we tested 18 Bulgaria SOCKS4 entries from our server in Germany. Through each one, the server fetched Cloudflare's trace page over plain HTTP and TLS, then Google's connectivity check.
| Tested 15 September 2026 | Entries |
|---|---|
| Tested | 18 |
| Did not accept a connection | 6 |
| Completed at least one request | 0 |
| Carried encrypted traffic | 0 |
| Opened Google | 0 |
| Certificate did not verify | 0 |
| Showed an exit address | 0 |
| Of those, exiting in Bulgaria | 0 |
HProxy test from one server in Germany. Every entry on the Bulgaria list was tested. Exit countries from Cloudflare's own trace. An entry that listed several protocols was tested over one: SOCKS5 first, then HTTPS, HTTP and SOCKS4.
None of the tested entries carried encrypted traffic all the way to the site.

How to use a free Bulgaria SOCKS4 proxy
Enter an entry as socks4://IP:PORT in your tool, then check the address a site sees before real work. Take several entries and rotate between them, because a free entry can drop between two checks.
Questions
Frequently asked.
Yes, every entry on this page is free to copy and use, with no signup. They are public and shared, so test one right before you rely on it.
At 16:51 UTC on 15 September 2026, 9 SOCKS4 entries in Bulgaria were alive. Among the 72 countries with live SOCKS4 entries, Bulgaria held the 12th largest number.
On 15 September 2026 the largest networks were Bulgaria, Vimtv and A1BG. Our address data classed none of the 9 live entries as datacenter space.
No, SOCKS4 only relays the connection, so encryption has to come from the site or your own tool.
Treat them as public, because whoever runs the server can read any traffic that is not encrypted. On 15 September 2026, all 9 live entries were flagged for recent abuse.
For work that has to keep running, HProxy sells Bulgaria proxies with city targeting. They are pay as you go with no subscription, and the balance never expires.

Docs and AI
The free list, in your assistant and in your code.
We built the MCP server and the CLI ourselves: the free proxy list is one tool call away in Claude, ChatGPT, Cursor or any assistant that speaks MCP, and the list's API is documented end to end.
Every product has its own reference in the docs. Something the list does not give you? Tell us.

MCP server
Built by us and hosted at mcp.hproxy.com: the free proxy list, the checker and the IP lookup as tools in Claude, ChatGPT, Cursor, VS Code or any assistant that speaks MCP. Nothing to install, no key.
CLI
The list from a terminal: hproxy list --country DE --limit 20, from the command line of the free HProxy app.
API docs
The free list's API, documented end to end with real responses: the filters, the formats, the limits.
llms.txt
The whole documentation as markdown for any model that reads: /llms.txt for the index, /llms-full.txt for everything.
Let your assistant pull the list
The pool is a free, keyless API and a documented markdown page. Hand your assistant one of these and it can fetch live proxies on its own, filtered the way you asked.
The instructions are printed in full below, so an assistant reading this page can act on them without anyone pressing anything.
All the machine lanes- MCP server
- Adds proxy_list, proxy_check and ip_lookup as tools your assistant can call by itself. Nothing to install.
claude mcp add --transport http hproxy https://mcp.hproxy.com/mcpClaude, ChatGPT, Cursor, VS Code, Windsurf or any assistant that speaks MCP: add https://mcp.hproxy.com/mcp as a remote server. This page's tool is proxy_list. - Command line
- The same tool without an assistant, from the free HProxy app's command line. Add --json for JSON.
hproxy list --country DE --protocol socks5 --limit 20Comes with the free HProxy app: hproxy.com/proxy-checker - REST, no key
- Plain HTTP with CORS on, which is all an agent with a fetch tool needs.
curl "https://hproxy.com/api/proxy-list?format=json&country=de&limit=20"
Instructions for an assistant, in full
Everything a model needs to call the free proxy list without an account: the endpoint, the parameters, the limits and the honest caveat. Readable straight off the page.
You can use HProxy's free proxy list, which needs no API key and no account.
GET https://hproxy.com/api/proxy-list?format=json returns the live pool as JSON. Useful query parameters: country (ISO alpha-2, e.g. de), protocol (http, https, socks4, socks5), anonymity (elite, anonymous, transparent) and limit. Add format=txt for plain ip:port lines instead.
Each proxy comes back with ip, port, protocols, anonymity, country_code, city, asn_org, latency_ms and uptime_24h. The pool is re-checked around the clock, so ask for it fresh rather than caching it.
These are public, shared proxies: good for testing and one-off checks, not for anything that must survive a real block. Full docs: https://hproxy.com/llms/free-proxy.txt
There is also an MCP server, so an assistant can call this as a tool instead of writing HTTP: add https://mcp.hproxy.com/mcp as a remote MCP server (nothing to install, no key) and use the proxy_list tool. In Claude Code the line is `claude mcp add --transport http hproxy https://mcp.hproxy.com/mcp`. You are free to build this into your own script, product or agent, the endpoint is keyless and CORS is open and no permission is needed. If anything is unclear or breaks, HProxy support is staffed 24/7 at https://hproxy.com/contact.Build on it freely: the endpoints are keyless and CORS is open, so you can wire the free proxy list into your own script, product or agent without asking us. If you get stuck, support answers around the clock, every day, at hproxy.com/contact. Generated markdown doc: hproxy.com/llms/free-proxy.txt.
About this list & IP removal
Every proxy here is aggregated from publicly available sources. We do not scan or collect these IP addresses ourselves: we verify entries that are already public (live status, latency, uptime) and store nothing else about the devices behind them. The list is provided as-is, with no warranty, for lawful use only, on the basis of our legitimate interest in a free, transparent proxy directory (Art. 6 (1) (f) GDPR). Never route passwords or sensitive data through a public proxy. If an IP address is yours and you'd like it removed, email legal@hproxy.com and we'll take it down (Art. 21 GDPR).
