Why EduSphere
What makes it better
than the alternatives
- 01
No ORM, no build pipeline
Plain ADO.NET and server-rendered Razor mean every query is visible and there's no npm, bundler or lock file to maintain.
- 02
Paid content is genuinely protected
Videos live outside the web root and stream only after an enrolment check, so sharing a link gives a non-buyer nothing.
- 03
Payments verified server-side
Orders are repriced on submit and confirmed with Stripe directly through both a return check and a signed webhook, so the browser is never believed.
- 04
Multi-currency that never corrupts history
Prices are stored once in a base currency and every payment records the rate it used, so changing a rate leaves past invoices untouched.
- 05
Built-in audit trail
Every administrative change, sign-in and data export is recorded with user, IP address and outcome, with no extra configuration.

Manually reviewedHow to read the quality report
What this is. Every project on Vibe96 goes through an automated audit of its source code before a reviewer in Dubai checks it by hand. The score is out of 100; 75 is the minimum to be listed, and any single failing check blocks a listing regardless of the score.
- Security
- No real credentials in the code, every data-changing route protected, admin areas role-gated, no SQL built from user input.
- Code structure
- A developer can navigate and extend it: clear module boundaries, no giant files, little copy-paste.
- Docs & completeness
- The setup guide, example config, schema and required files the builder committed to are actually in the archive.
- Dependency health
- Packages pinned, no known critical vulnerabilities, no abandoned libraries in production paths.
- Build & deploy
- A clean machine can restore, build and start it by following the shipped instructions.
Warnings are problems that didn't block the listing; they stay visible here until a later version clears them. The audit reads the code — it does not run it — so always try the live demo before you buy. Lines of code are counted from the same audited archive.
What to know before you buy
3 non-blocking findings shown publicly: no real secrets found; weak defaults in appsettings.json need hardening; strong authentication and role guards; missing ownership checks on student profile reads; good separation of concerns with minor duplication and some configuration hard-coding. The seller has been notified; fixes ship in the next version.
