What Is a Mockup Generator?

A mockup generator is an online tool that wraps your screenshots in realistic device frames — like an iPhone bezel, a MacBook shell, or a browser window — and places them on professional backgrounds. The result looks like a marketing asset you'd see on a landing page, App Store listing, or pitch deck.

Good mockup generators save hours compared to doing it manually in Photoshop or Figma. They're especially valuable for indie developers and small teams who don't have a dedicated designer.

How We Evaluated Each Tool

We tested every tool in this list by uploading the same set of screenshots (a web app, a mobile app, and a landing page) and comparing the output. Here are the criteria we used:

1. SnapMock — Best Overall Free Mockup Generator

Website: snapmock.app

SnapMock is a 100% client-side mockup generator that processes everything in your browser. Your images never leave your device, which makes it the most private option on this list. It supports browser chrome (macOS, Safari, Arc, Windows), phone frames (iPhone 16 Pro, iPhone 17 Pro, Pixel 9 Pro), laptops, and tablets.

What sets SnapMock apart is the combination of features you usually only find in paid tools: mesh gradient backgrounds, perspective/isometric views, custom image backgrounds, multi-image grid layouts, and an App Store screenshot generator with proper dimensions for iOS and Android.

The template system lets you apply pre-configured looks with one click — like "Twitter Card" or "Product Hunt" — which is a huge time-saver for social media marketers.

✓ Pros

  • 100% free, no signup, no watermark
  • Fully client-side (maximum privacy)
  • 20+ gradient and mesh backgrounds
  • Perspective & isometric views
  • App Store screenshot generator built-in
  • Multi-image layouts (grid, side-by-side)
  • 2× retina export

✗ Cons

  • No SVG export
  • No collaboration features
  • Relatively new (smaller community)

2. Shots.so

Website: shots.so

Shots.so has been a popular choice since 2023. It offers a clean interface with solid gradient options and browser mockup frames. The free tier gives you basic functionality, but many features — including 3D perspectives, custom backgrounds, and high-res exports — require a paid plan starting at $5/month.

If you're a heavy user willing to pay, Shots.so is polished. But for occasional use, the free tier feels restrictive. It also uploads your screenshots to their servers for processing, which may be a concern for confidential product screenshots.

✓ Pros

  • Beautiful, polished output
  • Good selection of frames
  • Code snippet mockups

✗ Cons

  • Many features behind paywall
  • Server-side processing
  • Watermark on free tier (some features)

If you're looking for a free Shots.so alternative, SnapMock offers most of the same features without the paywall.

3. Screely

Website: screely.com

Screely is a minimal tool focused on browser window mockups. You upload a screenshot, and it wraps it in a simple macOS-style window with traffic light buttons. That's about it. There are no phone frames, no gradient backgrounds, and very limited customization.

However, Screely does one thing and does it well. It's fast, clean, and processes images client-side. If all you need is a basic browser frame with no frills, Screely works.

✓ Pros

  • Dead simple — one-click browser frame
  • Client-side processing
  • Fast and lightweight

✗ Cons

  • Browser frames only (no devices)
  • Very limited customization
  • No gradient backgrounds

4. BrowserFrame

Website: browserframe.com

BrowserFrame specializes in — you guessed it — browser frames. It supports Chrome, Firefox, Safari, and Opera on macOS, Windows, and Linux. You can enter a URL and it will take a screenshot automatically, or upload your own image.

The URL-to-screenshot feature is unique and useful for documentation. However, the backgrounds are limited to solid colors and basic gradients, and there's no device frame support for phones or tablets.

✓ Pros

  • URL-to-screenshot feature
  • Multiple browser styles (Chrome, Firefox, etc.)
  • OS-specific frames

✗ Cons

  • Browser frames only
  • Server-side processing for URL screenshots
  • Limited background options

5. Smartmockups

Website: smartmockups.com

Smartmockups (now part of Canva) takes a different approach — it uses photorealistic mockup templates with real-world scenes. Think: your app displayed on an iPhone sitting on a wooden desk, or your website on a MacBook in a coffee shop.

The free tier includes a decent selection of templates, but the best ones require Canva Pro. It's great for marketing materials but overkill if you just need a clean device frame around a screenshot.

✓ Pros

  • Photorealistic scenes
  • Huge template library
  • Integrated with Canva

✗ Cons

  • Best templates require Canva Pro
  • Slower workflow (pick template, upload, adjust)
  • Server-side processing

6. MockUPhone

Website: mockuphone.com

MockUPhone focuses on device mockups with an impressive catalog of real devices — not just iPhones, but Samsung Galaxy, Google Pixel, iPad, Apple Watch, and even TVs. You upload a screenshot and it places it into a photographic device image.

The downside is the lack of background customization. Your mockup comes with a plain white or transparent background, and there's no way to add gradients, shadows, or padding. You'd need to add those in another tool.

✓ Pros

  • Wide device catalog
  • Photographic device renders
  • Free and straightforward

✗ Cons

  • No background customization
  • No browser frame options
  • Dated device models

7. Dimmy.club

Website: dimmy.club

Dimmy.club is a quirky little tool for placing your screenshots into device mockups. It supports basic devices (iPhone, iPad, MacBook, iMac) with color background options. The interface is simple and gets the job done quickly.

However, it hasn't been updated in a while. The device frames look dated (iPhone X era), and there's no support for modern devices, perspectives, or advanced backgrounds.

✓ Pros

  • Simple and fast
  • Multiple device types
  • Completely free

✗ Cons

  • Outdated device frames
  • Limited background options
  • No longer actively maintained

8. ScreensTab

Website: screenstab.com

ScreensTab generates beautiful 3D-perspective mockups from screenshots. The 3D effect is its killer feature — screenshots appear to float in space at various angles, which looks fantastic for hero sections and presentations.

The free tier includes watermarked exports, and removing the watermark requires a one-time purchase. If 3D is your thing, it's worth considering, though SnapMock's perspective feature offers similar effects for free.

✓ Pros

  • Stunning 3D perspective effects
  • Clean, modern interface
  • One-time purchase (not subscription)

✗ Cons

  • Watermark on free exports
  • Limited device frames
  • No multi-image layouts

9. Pika

Website: pika.style

Pika is an open-source screenshot beautifier that's gained popularity on Product Hunt. It offers browser frames, gradients, and some phone mockups. The open-source nature means you can self-host it if privacy is a concern.

The tool is solid for basic use cases but lacks the polish and feature depth of dedicated tools. Perspective views, mesh gradients, and App Store screenshot generation aren't available.

✓ Pros

  • Open source (self-hostable)
  • Good basic features
  • Growing community

✗ Cons

  • Limited device frames
  • No App Store screenshot generator
  • Less polished than paid alternatives

10. Freeshots.app

Website: freeshots.app

Freeshots is a newcomer focused on social media mockups. It provides pre-sized canvas templates for Twitter, Instagram, LinkedIn, and more, with device frames embedded. It's good for quick social media assets but limited in customization.

✓ Pros

  • Social-media-first design
  • Pre-sized templates
  • Free tier available

✗ Cons

  • Limited to social media sizes
  • Newer tool (fewer features)
  • Some features require signup

Quick Comparison

Here's a summary of how the 10 tools stack up on the criteria that matter most:

SnapMock — Browser + Phone + Laptop + Tablet frames · 20+ gradients + mesh · Perspectives · Client-side · Free, no signup
Shots.so — Browser + Phone frames · Good gradients · 3D (paid) · Server-side · Free tier limited
Screely — Browser frame only · White/basic BG · No perspective · Client-side · Free
BrowserFrame — Browser frames · Basic BG · No perspective · Server-side (URL) · Free
Smartmockups — Photorealistic scenes · N/A · N/A · Server-side · Free tier + Canva Pro
MockUPhone — Phone + Tablet + Watch · White/transparent · No · Server-side · Free
Dimmy.club — Phone + Laptop · Solid colors · No · Client-side · Free
ScreensTab — Browser frame · Gradients · 3D (watermark) · Server-side · Freemium
Pika — Browser + basic phone · Gradients · No · Client-side (OSS) · Free
Freeshots — Social media templates · Pre-set · No · Server-side · Free tier

Our Verdict

If you want the most features for $0 — including device frames, perspectives, mesh gradients, App Store screenshot generation, and complete privacy — SnapMock is the best free mockup generator in 2026.

For photorealistic scene mockups, Smartmockups is hard to beat (if you have Canva Pro). For the absolute simplest browser screenshot, Screely does the job in seconds. And if open source matters to you, Pika is worth trying.

But for the all-around best free tool that respects your privacy and doesn't gate features behind a paywall? SnapMock wins.
