Local proxy checks
Requests originate from the desktop app on the user machine, preserving the user to proxy to target network path.

Zenu Proxy Tester
Test proxy lists against the sites you actually care about. Checks run from your computer through the proxies you paste, not through Zenu infrastructure.
HTTP and HTTPS CONNECTSOCKS5 supportLocal privacy auditCSV exportNo telemetry
Built for drop prep
Check reachability, latency, and target-specific blocking before you run tasks.
Paste a list, review proxy format, target URL, duplicate, and target-load preflight signals, then export or copy the proxies that are actually usable.
Target-specific results
See passed, slow, reached, blocked, and failed checks per target with latency, HTTP status, attempts, and observed exit IPs. Readiness verdicts, grouped diagnostics, and copy actions make cleanup fast.
Operational exports
Filter by proxy, target, status, latency, Exit IP, or attempts, then retest the exact visible pairs. Export CSV, JSON, or a masked HTML report with run settings and the readiness verdict.
List import and cleanup
Import local text or CSV proxy files, review input hygiene preflight signals, remove duplicate lines, and catch malformed proxy or target rows before checks start.
Local setup files
Save proxy lines, targets, and run settings to a user-controlled JSON file, save the currently visible result subset, or retest exact visible proxy-target pairs.
Target summaries
Compare usable rate, average latency, blocked responses, reached responses, and failed checks, then filter or copy usable or non-usable proxies for one target. Reached non-success responses stay separate for review.
Proxy health ranking
Rank each proxy line by target coverage, usable result rate, average latency, and observed exit IP count, then filter the table or copy one source line.
Request budget preflight
Preview total checks, max retry attempts, per-target concurrency, and pressure before a batch touches a target site.
Local privacy audit
See the local tester API origin, session-token state, redacted target hosts, and explicit no-relay/no-telemetry status before sharing a safe audit summary.
Drop-ready presets
Use judge, Google, Shopify, SNKRS, and Pokemon Center presets, or test the exact URL planned for your task group.
See it in action
Review the app before you download it.
The tester shows proxy health, target-level outcomes, exit IP signals, and export tools in one local desktop view.
Download

Enter an email for release updates, or skip it and download directly. The app does not send proxy lists, credentials, target URLs, or test results to Zenu.
SHA256 checksum links are listed under each build so you can verify the installer after download.

FAQ
Designed to avoid the hosted-checker trap.
Why not run this as an online checker?
A hosted checker would make requests from Zenu servers. The desktop app keeps the relevant path on the user machine. Read the comparison.
Does the app store credentials?
No. Proxy credentials stay in the local app session and API responses mask credentials before rendering results.
Can I import a proxy file?
Yes. Import text or CSV files locally, clean duplicates, then run the same list against one or more target URLs.
How do I verify the download?
Download the installer and its SHA256 checksum file, compute the installer hash locally, then compare it before opening the app.
How do target summaries help?
They show whether proxies are usable on each specific site, instead of burying target-specific blocks inside a flat result table.
