TesterAgentCheck your website or Android app
TesterAgent is an online tool that checks a website or an Android app (APK) and gives you one report with a fix for every problem it finds. A website check covers speed on desktop and slow mobile, UX/UI and accessibility, translations, functions such as forms, search and links, and the hosting setup. Reports are in English and Lao. One free check needs no account; plans are Free ($0), Pro ($19/month) and Business ($49/month), in US dollars.
Website
We check 3 pages in a real browser: speed, UX/UI, translation, functions and hosting (security best-practice checks need an account).
By running a check you agree to the Terms and the Acceptable Use Policy.
App (APK)
No account needed for one free check — a website or an app. The report link works for 7 days. Create a free account to keep every report. · See a sample report
What we check
Speed
Load time on desktop and slow mobile, page weight, what slows you down.
UX / UI
Mobile layout, accessibility, tap targets, contrast, broken images — with screenshots.
Translation
Every language your site supports: untranslated text, cut-off words, suspected wrong words, Thai letters in Lao.
Functions
Search, forms, buttons, links and 404 pages actually work.
Security best practice
Passive checks on websites you own: HTTPS, security headers, cookie settings, files that should not be public (paid plans).
Scale
Hosting, CDN, caching and compression: will it survive more visitors?
Android apps
Upload an APK: Google Play target API, 16 KB pages, permissions, signing, hard-coded keys and every translation.
How it works
- Create an account and add your website address.
- Choose what to test: public pages, the logged-in area, or both.
- Press Run audit. Each check runs in turn; you get the report in minutes.
- For an Android app, just upload the .apk — no verification needed.
Who it is for
- Agencies that hand over websites and apps to clients and want a checked, documented launch.
- Small businesses in Laos, Thailand and South-East Asia that want their site fast on mobile and correct in every language.
- App developers preparing a Google Play release (target API, 16 KB page size, permissions).
Safe by design
- Only sites and apps you own or are allowed to test.
- Pages behind a login: you log in yourself in a live view — we never see or store your password.
- Production safe mode: we never submit forms, pay, delete or log out.
- Uploaded APKs are deleted right after the check. How we test

Frequently asked questions
Is the check really free?
Yes. One website or app check every 30 days without an account (3 pages, no security checks). The report link works for 7 days. A free account keeps your reports.
Can I check someone else's website?
No. Only sites and apps you own or have permission to test.
Will the check change anything on my site?
No. The default production safe mode never submits forms and blocks any change our clicks could cause.
What language is the report in?
English and Lao.
Does it check security?
Paid plans include passive security best-practice checks for websites you own: HTTPS, security headers, cookie settings and files that should not be public. They read only what a normal visitor’s browser receives.
