Paste the list you plan to run
Drop in raw proxy lines or import text/CSV. The app flags malformed rows, duplicates, and anything that should be cleaned up before a task.

Zenu Proxy Tester
Test a proxy list against the exact sites your tasks will hit. Keep the lines that pass, spot slow or blocked routes, and dig into diagnostics only when a run needs cleanup.
Simple mode by defaultAdvanced diagnosticsRuns from your machineHTTP / CONNECT / SOCKS5Target-by-target verdictsNo proxy upload
Built for drop prep
Find the proxies worth running before the task starts.
Simple mode keeps the first run focused on readiness, status totals, and target summaries. Advanced mode adds input hygiene, duplicate counts, request pacing, setup files, diagnostics, Exit IP review, and report exports for deeper cleanup.
Test the real targets
Check Shopify, SNKRS, Pokemon Center, Google, judge endpoints, or the exact URLs your task group will hit.
Measure from your machine
Runs go from your desktop through HTTP, HTTPS CONNECT, or SOCKS5 proxies, so latency, status, and exit IP match the route you actually use.
Open the deeper checks when needed
Use Advanced mode for request profiles, pacing, retries, local setup files, privacy audit details, diagnostics, and exit IP review.
Keep only the winners
Copy usable proxies, export filtered CSV, retest a narrowed view, or save masked JSON reports when you need a support-friendly record.
See it in action
A clean run view for messy proxy lists.
Paste the list, add the targets, run the check, then filter down to the proxies you would actually trust in a live task.
Target-by-target pass rates
Separate Shopify, SNKRS, Pokemon Center, and custom URLs instead of trusting one blended health score.
Exit IP visibility
Catch shared, mixed, or rotating egress before those sessions land in a real task group.
Clean exports
Copy the visible winners after filtering by target, status, latency, diagnostic note, or exit IP.

FAQ
Built for the route your tasks actually take.
What is Simple mode?
Simple mode is the quick path: paste proxies, choose targets, run the check, review readiness, copy usable proxies, and export CSV.
When should I use Advanced mode?
Use Advanced mode when you need request profiles, queue delay, retries, slow thresholds, privacy audit details, local setup files, Exit IP insights, grouped diagnostics, retests, or masked reports.
Why not run this as an online checker?
An online checker tells you how its server reaches a site. This app tests from your machine, through your proxies, to the targets you choose. Read the comparison.
What happens to my proxy list?
It stays in the desktop app. Results use masked credentials, and this page never asks you to upload proxy lines to Zenu.
Does this work with non-Zenu proxies?
Yes. Paste HTTP, HTTPS CONNECT, or SOCKS5 lists from any provider and test them locally.
What should I test before a drop?
Use the same target URLs you plan to run, then export only the lines that pass or come back acceptably slow for each target.
