⚡ Pulse — Proxy Checker

Pulse is a free, open-source proxy checker and proxy tester for the desktop. Paste a proxy list — or let Pulse scrape thousands of free proxies from public sources — and it verifies which are alive across HTTP, HTTPS, SOCKS4 and SOCKS5, streaming results live. Every working proxy is enriched with its country, resolved exit IP, ISP/ASN, a quality score, and a risk rating — all computed locally from a bundled GeoIP database, so there are no API keys and no rate limits. Keep a curated pool of working proxies per protocol, recheck it anytime, filter by risk/country/latency/quality, and export the results.

Built with Tauri + Rust (native, lightweight) and a Node.js checking engine. Runs on macOS and Windows. MIT licensed.

• Three modes — Paste your own, find Free Proxies from public lists, or manage a Saved pool.
• 4 protocols — HTTP, HTTPS, SOCKS4, SOCKS5.
• Free proxy finder — pulls thousands of fresh proxies per protocol from public lists and checks which are alive, streaming results live.
• Rich results — resolved exit IP, country (with flag), quality %, and risk level for every working proxy — all computed locally from a bundled IP database. No third-party scoring API, no rate limits.
• Filters — risk, country, max latency, min quality. Copy / Export / Save respect the active filters.
• Saved pools — save working (or filtered) proxies into a persistent per-protocol pool. Recheck anytime, prune dead ones, copy or export.
• Export — writes a timestamped proxies-<scheme>-<date>.txt.
• Fully self-contained — the desktop app bundles everything; end users need nothing installed.

Paste & check any list	Maintained saved pool, per protocol

Grab the latest build for your platform from the Releases page:

• macOS — Pulse_x.y.z_aarch64.dmg
• Windows — Pulse_x.y.z_x64-setup.exe

macOS builds are unsigned — on first launch, right-click the app → Open (or allow it under System Settings → Privacy & Security).

Pulse is a Tauri (Rust) desktop shell with a Node.js checking engine and a Vite frontend. For each proxy the engine:

1. connects through the proxy to lightweight IP-echo endpoints (rotating, with fallback) to confirm it actually forwards traffic and read its exit IP;
2. geolocates the exit IP locally against a bundled DB-IP Lite database (country, ISP, ASN) — no API calls, no limits;
3. computes a quality % (latency + anonymity + datacenter detection) and a risk rating (Low / Medium / High).

Requirements: Node 18+, Rust (stable), and the Tauri prerequisites for your OS.

# engine
cd host && npm install && npm test

# frontend
cd ../ui && npm install && npm run build

# desktop app (dev)
cd ../src-tauri && cargo tauri dev

To produce a release bundle:

cd host && npm run pkg                        # self-contained engine binary
cp host/dist/PulseEngine src-tauri/assets/    # stage it as a resource
cd src-tauri && cargo tauri build             # -> .dmg / .exe

├─ host/          Node.js checking engine (+ bundled GeoIP data)
├─ src-tauri/     Rust / Tauri shell (commands, persistence, window)
├─ ui/            Vite frontend
└─ .github/workflows/release.yml   CI — builds macOS + Windows on a version tag

Pushing a version tag triggers CI, which builds the macOS .dmg and Windows .exe and attaches them to a GitHub Release:

git tag v1.0 && git push origin v1.0

Contributions are very welcome! 🎉 Bug fixes, new proxy-list sources, better quality/risk heuristics, UI polish, docs — PRs of all sizes are appreciated.

1. Fork the repo and create a branch: git checkout -b my-feature
2. Make your change, keep the existing style, and run cd host && npm test
3. Open a pull request describing what and why

The Free Proxies finder pulls public proxy lists at runtime from these community-maintained projects — huge thanks to their authors:

Pulse fetches these lists live and discards them after checking — it does not bundle, store, or redistribute any provider's proxy data.

All checking happens on your machine. The only network traffic is: fetching public proxy lists, the proxy connections you ask it to test, and lightweight IP-echo lookups to read each proxy's exit IP.

Pulse's source code is MIT — free to use, modify, and distribute.

The bundled DB-IP Lite geolocation data is a separate work under CC BY 4.0 (attribution required) — see NOTICE.md. MIT covers the code, not the data.
