Cycling through all six. Tap any point to stop.

Measured on six things

Create free ad mockups for eight platforms. Edit copy and images, preview desktop and mobile, and export PNG, JPG, or SVG. No sign-up.

Security

HTTPS enforced and SPF present, but no HSTS, CSP, frame protection, Referrer-Policy, or DMARC — 3/12 checklist points. Local image processing is a genuine privacy plus, but headers are thin.

AdViewport

About this app

AdViewport is a free browser-based ad mockup tool for marketers, designers, freelancers, and agencies. Build previews for Facebook, Instagram, Google Ads, LinkedIn, X, Snapchat, TikTok, and YouTube. Edit creative, copy, and calls to action, compare desktop and mobile views, and export PNG, JPG, or SVG. Share links restore text and settings; uploaded images stay in your browser and are not included in shared links. No account is required. These are design previews; AdViewport does not publish campaigns or predict performance.

Scout Review

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

AdViewport is a free, browser-based ad mockup generator covering eight platforms — Facebook, Instagram, LinkedIn, X, Google Ads, Snapchat, TikTok, and YouTube — with desktop/mobile comparison, four canvas ratios, and PNG/JPG/SVG export. It's fast (Lighthouse desktop 99, mobile 88), frictionless (no account, no sign-up), and privacy-conscious (images processed locally, excluded from shared links). The design is a clean dark-mode studio aesthetic that reads as intentional. The weak points are security headers (3/12 checklist points, no HSTS/CSP/DMARC) and accessibility polish (contrast and unlabeled form elements). There's no help center beyond the homepage FAQ, and no traction signals yet given the domain is barely three months old. For freelancers and small agencies who need quick, review-ready ad mockups without opening eight dashboards, it's a genuinely useful free tool — just don't mistake it for a campaign planner, which the site is honest about.

Measure by measure

Usability

No sign-up, instant workspace, shareable links that restore settings, and an FAQ covering cost, privacy, and export. Onboarding friction is about as low as it gets for a browser tool.

Design

Dark 'studio' aesthetic with terminal-style headings and a clean feature grid. Landing page is well-organized and modern, though it leans on a familiar SaaS template look.

Speed

Lighthouse desktop 99/100 and mobile 88/100, with CLS 0.001 and TBT 37ms. Mobile LCP of 3.1s is the one soft spot; otherwise this is a snappy, lightweight page.

Security

HTTPS enforced and SPF present, but no HSTS, CSP, frame protection, Referrer-Policy, or DMARC — 3/12 checklist points. Local image processing is a genuine privacy plus, but headers are thin.

Accessibility

Lighthouse a11y 92/100 with a language switcher present, but contrast failures and unlabeled form elements remain. No published WCAG statement or a11y documentation found.

Growth

A real, specific problem — cross-platform ad mockups without opening eight dashboards — with concrete differentiators: no sign-up, local image processing, shareable links. Domain is 0.1 years old, so traction is nil, but the wedge is legible.

Improvement areas

Security headers: only 3/12 checklist points — no HSTS, CSP, frame protection, Referrer-Policy, or DMARC
Accessibility: Lighthouse flags insufficient color contrast and form elements without associated labels
Documentation: no help center or walkthrough beyond the homepage FAQ
No published accessibility statement or WCAG conformance target

Design & Usability

AdViewport's design is a competent dark-mode studio aesthetic — terminal-style headings, a clean feature grid, and a landing page that gets out of the way. It won't win awards, but it reads as intentional rather than templated, and the '//' branding gives it a distinct voice. Usability is where it earns its keep: no sign-up, no email wall, an instant workspace, and shareable links that restore platform, copy, format, CTA, and layout settings. The FAQ covers the five questions a buyer actually asks — cost, image handling, export formats, accuracy, and whether this replaces campaign planning. For a free browser tool aimed at freelancers and agencies, that's a genuinely low-friction onboarding story. The gap is depth: there's no visible help center, no video walkthrough, and no documentation beyond the homepage FAQ, so anything beyond the happy path is guesswork.

Speed & Security

Speed is a real strength. Lighthouse desktop scores 99/100 and mobile 88/100, with a near-perfect CLS of 0.001 and TBT of just 37ms — this is a lightweight page that doesn't fight the browser. The only soft spot is mobile LCP at 3.1s, which is fine but not exceptional. Security is the weak flank. HTTPS is enforced and SPF is configured, but the probe found no HSTS, no CSP, no frame protection, no X-Content-Type-Options, no Referrer-Policy, no Permissions-Policy, and no DMARC — 3 of 12 checklist points. For a tool that handles uploaded creative assets, that's thin. The saving grace is architectural: images are processed locally in the browser and excluded from shared links, which is a meaningful privacy design choice that reduces the blast radius of the missing headers. Still, a free tool with no account system has little to protect, which softens the risk.

Accessibility & Growth

Accessibility lands at 92/100 on Lighthouse, with a language switcher suggesting multi-language intent. Two real failures remain: insufficient color contrast and form elements without associated labels — the latter is a straightforward fix that would push this into the mid-90s. There's no published WCAG statement or accessibility documentation, which is normal for a tool this young but worth adding. Growth is a judgement on the idea, not the traction. The problem is real: marketers and freelancers currently mock up ads by screenshotting platform previews or rebuilding them in Figma. AdViewport names a specific customer (freelancers, agencies, designers), a specific workflow (eight platforms, one workspace), and concrete differentiators (no sign-up, local image processing, reproducible share links). The category has headroom — ad creative review is a recurring, unglamorous chore. The honest limit is that Canva, Figma, and platform-native preview tools all sit adjacent, and the free positioning makes monetization unclear. The domain is 0.1 years old, so there's no traction signal yet — just a legible wedge.

Conclusion

The pitch is narrow and honest: make ad mockups, export them, share them, don't pretend to be a media buying platform. That restraint is refreshing in a category full of tools that promise to 'optimize your funnel' and deliver a drag-and-drop editor. AdViewport does one thing, does it fast, and asks for nothing — no account, no email, no credit card. The trade-off is depth: no help center, thin security headers, and accessibility gaps that a single afternoon of work could close. If you're a freelancer who currently screenshots platform previews for client decks, this saves you real time today. If you need campaign planning, performance prediction, or team collaboration, look elsewhere — and the site will tell you the same thing.

Suggestions for improvement

Add HSTS, CSP, X-Content-Type-Options, Referrer-Policy, and DMARC headers — the probe found only 3/12 checklist points.
Fix the two Lighthouse a11y failures: color contrast and form elements without associated labels.
Publish a short help center or video walkthrough — the homepage FAQ is the only documentation available.
Add an accessibility statement and WCAG conformance target to signal intent beyond the automated score.
