In-house product — not external client workPublic comparison platform with an internal publishing and verification back office
LATYNEX Labs — Software Comparison & Data Tools Platform
A public software comparison site and the internal publishing platform behind it, built so that every price and fact carries a source and a check date.
Software pricing pages change often, use different units and are easy to misread. Buyers need comparisons they can check, and a publisher needs to know where every number came from, when it was last checked and what is safe to publish.
Solution
What LATYNEX Digital built
One engineering case across two surfaces: a calm public reading interface that shows the source and check date beside every value, and an internal platform that makes provenance a database invariant and routes every change through an explicit verification workflow.
What it demonstrates
What this shows we can build
A public site and the editorial back office behind it: catalogue management, a fact-verification queue, a guide editor and a source register.
Data discipline in code: every value carries a source and a check date, pending revisions never replace public values until verified, different currencies are never converted and different units are flagged.
How the same capability could serve another business
A business that publishes product, price or technical data could get a public site backed by an editing and verification workflow rather than a loose CMS.

Product showcase
The product, screen by screen
From a sourced record to a public pagePublic catalogue: category and product pagesCompare and calculateInternal platform: sources, queue and editor
Public pages are the live site; internal screens come from a demo instance with sample data. Interface text on internal screens was translated to English for presentation.
How it works
From input to outcome
01
Every value has a source
The database refuses a public value that has no source and check date.
02
Changes wait for an editor
Proposed values enter a verification queue where an editor opens the source, compares it with the public value and verifies or rejects it.
03
Only verified values go live
A value is shown as verified only after an editor has confirmed it; everything else is labelled pending.
04
Checks run on a schedule
Scheduled jobs monitor sources, scan for stale data and check links.
Technical approach
How it is engineered
A Next.js 16 and React 19 application in TypeScript with Tailwind CSS 4, Drizzle ORM and PostgreSQL. The same codebase serves the public site and a private editorial console protected by argon2id passwords and mandatory TOTP two-factor authentication; database triggers and constraints enforce source provenance, scripted jobs run the scheduled checks, and Caddy serves the site over HTTPS.

What this page does and does not claim
The public site is an early public beta and is not indexed by search engines.
Some values are labelled pending or source changed on the live site and are not presented here as fully verified.
Prices are third-party vendor data and change. No affiliate revenue or approved programmes are claimed.
