Measured on six things

AliExpress price history and discount checker.

Speed

Desktop Lighthouse 93/100 but mobile only 69/100 with a 7.1s LCP — the data-dense homepage is heavy on phones. CLS 0 and TBT 83ms are clean; the mobile load is the weak link.

Scout Review

Written by AI from measured evidence, scored out of 100.

PriceProven is a focused, honest tool for a real annoyance: AliExpress sellers inflating 'discounts' and listing the same product at wildly different prices. It tracks 81,638 listings with 48 days of its own recorded prices, shows dated history, flags duplicate listings, and works via a Chrome extension or a paste-a-link box — free, no sign-in. The design is data-dense but credible, usability is genuinely low-friction, and security headers are above average for the stage. Weak spots: mobile performance (7.1s LCP), no DMARC, no published compliance or accessibility documentation, and no help center. It's early — domain registered 2026 — but the core value prop is concrete and demonstrable, which is more than most price trackers manage.

Measure by measure

Usability

Paste a link or install the extension, no sign-in required, and four plain-language prompts map to the outputs. Onboarding is genuinely low-friction, though there's no visible help center or docs.

Design

A data-first landing page that leads with live numbers (81,638 listings, 48 days tracked) and a concrete duplicate-listing demo. Functional and credible, but dense and text-heavy rather than visually refined.

Speed

Desktop Lighthouse 93/100 but mobile only 69/100 with a 7.1s LCP — the data-dense homepage is heavy on phones. CLS 0 and TBT 83ms are clean; the mobile load is the weak link.

Security

Strong header hygiene: HTTPS enforced, HSTS, CSP, frame protection, Referrer-Policy, Permissions-Policy — 11/12 probe points. DMARC is missing and there's no published SOC 2, ISO or pen-test claim.

Accessibility

Lighthouse a11y 90/100 with EN/FR support, but contrast failures and malformed definition lists (<dl>/<dt>/<dd>) are flagged. No published WCAG statement or accessibility page found.

Growth

A real, specific problem — AliExpress fake discounts and duplicate listings — that Honey, CamelCamelCamel and Keepa don't solve for AliExpress. Clear wedge, but a narrow single-marketplace niche.

Improvement areas

Mobile performance: 7.1s LCP and a 69/100 Lighthouse score need lazy-loading or pagination fixes.
Documentation: no help center, FAQ or docs beyond four homepage prompts.
Compliance and a11y paperwork: missing DMARC, no SOC 2/ISO claim, no WCAG or accessibility statement.

Design & Usability

PriceProven's design is unapologetically data-first: the homepage leads with live counters (81,638 listings tracked, 48 days of recorded prices) and a duplicate-listing demo showing the same photo at $2.42 and $5.00 from two shops. It's credible and concrete, but dense and text-heavy — more dashboard than landing page. Usability is where it shines: paste any AliExpress link or install the Chrome extension, no sign-in required, and four plain-language prompts ('Was it cheaper before?', 'Is this discount real?') map straight to the outputs. The friction is genuinely low. The gap is support material — no visible help center, docs, or FAQ beyond the homepage prompts, which leaves new users to figure out edge cases on their own.

Speed & Security

Speed is split: desktop Lighthouse scores 93/100, but mobile drops to 69/100 with a 7.1s LCP — the data-dense homepage is heavy on phones, though CLS 0 and TBT 83ms show the layout is stable and the main thread isn't choked. Security is a genuine strength for an early-stage tool: the HTTP probe found HTTPS enforced, HSTS, CSP, frame protection, X-Content-Type-Options, Referrer-Policy and Permissions-Policy — 11 of 12 checklist points. The gaps are DMARC (missing, so email spoofing is possible) and the absence of any published SOC 2, ISO, pen-test or bug-bounty claim. For a free, no-sign-in tool that reads AliExpress pages, the header hygiene is above category norms; the compliance paperwork simply isn't there yet.

Accessibility & Growth

Accessibility lands at 90/100 on Lighthouse with EN/FR language support, but the failing audits are real: insufficient color contrast and malformed definition lists (<dl>/<dt>/<dd> ordering), which affect screen reader users parsing the price data. No WCAG statement or accessibility page is published. Growth is a judgement on the idea: PriceProven names a specific, real problem — AliExpress's fake strike-through discounts and duplicate listings priced differently by different shops — and the listed alternatives (Honey, CamelCamelCamel, Keepa) are all Amazon-first or coupon-first, not AliExpress price-history tools. That's a genuine wedge. The limit is scope: a single-marketplace niche, dependent on AliExpress's data, with a free model and no visible monetization beyond the homepage's 'How we make money' note.

Conclusion

If you buy from AliExpress with any regularity, PriceProven answers a question the platform actively obscures: is this discount real? The duplicate-listing detection alone justifies a bookmark. It's not polished, it's not fast on mobile, and it has no compliance paperwork to speak of — but it does the one thing it promises, for free, without a sign-in wall. For a tool this young, that's a solid foundation. The next steps are obvious: fix the mobile LCP, add DMARC, publish a help page, and figure out how it sustains itself.

Suggestions for improvement

Fix the 7.1s mobile LCP — the data-dense homepage needs lazy-loading or server-rendered pagination on phones.
Add a DMARC record to complete the email security posture alongside the existing SPF.
Publish a help center or FAQ covering edge cases: short links, variants, pack sizes, and shipping differences.
Add an accessibility statement and fix the contrast and definition-list failures flagged by Lighthouse.
