A Simpler, More Affordable Alternative to Applitools

Applitools is a serious, well-funded visual testing platform built around Visual AI. It is genuinely good at what it is designed for, and for some teams it is the right answer. But it is designed around a particular shape — an SDK living inside your automated test suite, priced for engineering organisations — and plenty of teams want something narrower and cheaper. This page lays out where the two products differ, honestly, so you can tell which shape you are.

What Applitools actually is

Applitools’ visual engine is Eyes, and its headline feature is Visual AI: instead of comparing pixels, it uses computer vision to decide which differences are meaningful and which are noise, which is what lets it ignore dynamic content and anti-aliasing. Around Eyes sits the Ultrafast Grid, which takes one local test run, captures a DOM snapshot, and re-renders it across many browsers and devices — Chrome, Firefox, Edge, Safari and IE, plus mobile emulation for iPhone, iPad, Samsung Galaxy and Kindle. More recently Applitools added Autonomous, a no-code layer for AI-generated tests.

The important thing to understand is how you drive it. The core product is integrated into your test code through one of 30+ SDKs — Selenium, Cypress, Playwright and the rest — where you add Eyes.check() calls to an existing functional test. Applitools now also offers a recorder, NLP authoring and a website crawler, but the platform’s centre of gravity is the SDK in your test suite. Diffy’s centre of gravity is a browser tab. That single difference drives most of what follows.

Pricing

The two tools count usage in comparable units. Diffy sells plans in screenshots per month, counting each page at each breakpoint. Applitools bills in checkpoints: a page checkpoint is a full-screen validation in one browser-and-viewport combination — the same idea as a Diffy screenshot — and a component checkpoint validates a single UI element. Because the Ultrafast Grid re-renders each check across every browser and viewport you target, checking one page across five combinations consumes five checkpoints.

Here is what each one costs today.

Diffy

Screenshots per month	Billed annually	Month-to-month
2,000	$67/mo	$80/mo
8,000	$125/mo	$150/mo
30,000	$250/mo	$300/mo

Diffy also has a free plan (two environments, one month of data retention).

Applitools

Plan	Price	Allowance
Starter	$667/mo (paid annually)	1,000 page checkpoints or 100,000 component checkpoints
Professional	Contact sales	From 150 active pages / 1,500 components
Enterprise	Contact sales	From 350 active pages / 1,500 components

Two things stand out.

The entry point. Applitools’ cheapest published plan is $667/mo and allows 1,000 page checkpoints. A 20-page site checked at three breakpoints is 60 page checkpoints per run; run it daily and you are at roughly 1,800 a month — already past the Starter plan, into Professional and a sales conversation. That same 1,800 screenshots a month is Diffy’s 2,000 plan at $67/mo. If most of what you want is full-page visual testing, that is an order-of-magnitude difference in price for comparable volume.

Above Starter, the price is a conversation. Applitools publishes exactly one number. Professional and Enterprise are “contact sales”, and their allowances are quoted in active pages rather than a monthly checkpoint count, so you cannot self-serve your way to a larger plan or know what it costs without talking to someone. Diffy’s three tiers are all listed, all self-serve, and you can upgrade in the dashboard.

To be fair to Applitools: the Starter plan is not only those 1,000 page checkpoints. It also includes 100,000 component checkpoints, unlimited users, and functional, cross-browser and accessibility testing in the same subscription. You are paying for a much broader platform. The question is whether you need that platform, or whether you need screenshots of your pages compared between environments.

Setup: a browser tab vs. an SDK in your test suite

Applitools is at its best when it lives inside a test suite you already run. You install the SDK for your framework, add Eyes.check() calls at the points you want validated, wire in your API key, and run the suite — locally or in CI — pointing the renders at the Ultrafast Grid. If you already maintain a Cypress or Playwright suite and have engineers who own it, this is a good fit and the Visual AI is a real payoff.

Diffy’s equivalent is a browser tab. You paste the URLs into a project, pick your breakpoints, and press a button — the URL list, the waits, the elements to mask and the schedule are all fields in the UI, editable by whoever needs to change them. That matters most when the person who wants visual testing is a designer, a site owner, or an agency PM rather than someone who writes and maintains automated tests.

When you do want automation, Diffy’s CLI and GitHub Action are there — but they are optional, not the price of entry.

Environments, not test batches

This is the deeper difference, and it is not about features.

Applitools is organised around test runs. Each run is a batch of checkpoints from your suite, compared against a baseline that Applitools tracks per branch and configuration. It is a model built to answer “did this test run change the UI?” — and it ties visual testing tightly to the functional test that produced it.

Diffy is organised around environments. Production, staging and development are first-class, and you can add custom ones. The question it answers naturally is “do these two deployed sites look the same?”:

• Does staging still match production before we go live?
• Did anything on production change overnight, without a deploy? Scheduled monitoring runs daily or weekly and compares an environment against itself over time.
• Does this Pantheon or Tugboat multidev match production?

Neither model is strictly better — they are aimed at different questions. If your visual testing is a step inside your automated tests, Applitools’ batch-and-baseline model is where it belongs. If you are comparing deployed environments, or watching a live site you did not just deploy to, that is Diffy’s native shape. For agencies and teams running CMS sites, this usually matters more than any single feature.

Handling real-world pages without writing code

Most of the effort in visual testing is not taking screenshots, it is stopping them from being noisy. Applitools handles a lot of this automatically — its Visual AI is designed to ignore dynamic content and rendering variation, and where it needs help you set ignore/layout regions and match levels in your test code. Diffy handles the same problems as settings in the UI:

• Log in before the screenshot. Presets for Drupal, WordPress and Netlify, plus a custom option; Diffy opens the login page, fills the credentials and continues. No test code required.
• Mock dynamic content. Give Diffy a list of selectors and it replaces their contents with placeholder text — the standard fix for sites that publish new articles between runs and can never be perfectly synced across environments.
• Remove or mask elements. Removal drops the element from the DOM; masking paints a visible rectangle over it, so reviewers can see what was hidden. Embedded videos and maps are masked by default.
• Inject custom CSS or JavaScript, set HTTP headers, cookies, and a custom User-Agent.
• Retina and dark mode are checkboxes.
• Any breakpoint between 240px and 3000px, as many as you like.
• Throttle the crawl by limiting concurrent workers, or route it through a single IP address so it can be allowlisted.

Comparison that understands vertical shifts

Pixel-perfect diffing has a well-known failure mode: change the height of something near the top of a page and every pixel below it moves, so the whole page lights up red. Applitools solves this with Visual AI and its match levels. Diffy solves it with a purpose-built diff algorithm.

Diffy runs a custom algorithm alongside pixel-perfect comparison that recognises vertical shifts. Add a line to your header and Diffy highlights the header — not the other 4,000 pixels that merely moved down. You can still switch to strict pixel-perfect comparison, and you can tune comparison sensitivity, when that is what you want — without reasoning about match levels in code.

A review UI built for hundreds of screenshots

Reviewing is where teams actually spend their time, so the UI is built for volume:

• Thumbnail view, with approval directly from thumbnails
• The same change grouped across every screenshot it appears in, so you approve it once
• Approve an individual change, a screenshot, or a page across all breakpoints
• Before/after slider
• Keyboard shortcuts for moving through a large set
• HTML source and the JavaScript console for the screenshot, for debugging
• Shareable links that work for people without a Diffy account

Integrations

• CLI tool for CI/CD, with examples for Pantheon, Tugboat and others
• GitHub Action that posts results back to the pull request
• Notifications via email, Slack and webhooks, with configurable thresholds
• Zapier, so a diff can open a ticket in your tracker
• Figma — pull design screenshots in and compare the build against the design
• Upload screenshots from Playwright or any other functional testing framework and use Diffy purely as the comparison and review layer
• Claude plugin, so you can create projects, capture screenshots and compare environments from a conversation — see below

Driving Diffy from Claude

Diffy publishes a Claude plugin that lets you run visual testing from a conversation instead of a dashboard or a CI config. It installs from the plugin marketplace in two lines:

/plugin marketplace add diffywebsite/diffy-skills
/plugin install diffy@diffy

That gives you ten skills under the /diffy: namespace, covering the whole loop rather than just capture:

• Project setup — create-project builds a project from base URLs, pages and breakpoints; get-project-settings exports the current config as YAML; update-project-settings changes pages, environments, breakpoints, masks, login settings and schedules
• Capture — remote-screenshot runs on Diffy’s servers, upload-screenshot captures a locally running app through the screenshot-worker container, and get-screenshot-info tells you when a capture finished
• Comparison — compare-screenshots diffs two screenshot sets, and get-diff-info returns the summary: percentage changed, a per-page table, and a JUnit report
• End to end — visual-diff runs a local before/after regression pass, and compare-environments compares two environments server-side

The distinction worth knowing is local versus remote. Local mode captures an app running on your own machine and needs Docker for the screenshot worker. Remote mode runs entirely on Diffy’s infrastructure, so there is nothing to install beyond the plugin itself.

In practice this is most useful in the middle of a change. You are already in Claude working on a template; asking it to compare staging against production and tell you which pages moved is faster than switching to a browser, and the JUnit output drops straight into a CI job when you want to make it permanent. It does not replace the UI — reviewing a few hundred screenshots is still a job for the review dashboard — but it removes the context switch when you just want to know whether something broke.

The plugin is MIT licensed and developed in the open at github.com/DiffyWebsite/diffy-skills.

Configuration you can version

Project settings export to YAML and import back, and Diffy keeps a revision history of settings changes, so you can see what was altered and when. Bulk operations let you trigger comparisons across many projects at once — useful if you maintain dozens of sites.

Where Applitools is the better fit

We would rather you pick the right tool than the cheaper one.

• Real cross-browser and cross-device rendering. The Ultrafast Grid renders one test run across Chrome, Firefox, Edge, Safari and IE, plus mobile emulation for iPhone, iPad, Samsung Galaxy and Kindle. Diffy tests responsive breakpoints in Chrome and WebKit — real engines, but a narrower matrix.
• Component and design-system testing. Applitools counts component checkpoints and integrates with Storybook, so a component library is a much better fit for Applitools than for Diffy’s page-level model.
• One platform for functional, visual, API and accessibility testing. If you want visual checks embedded in a broader automated test suite, that is exactly what Applitools is built for.
• Visual AI and no-code AI authoring. Applitools’ Visual AI auto-classifies differences, and Autonomous generates tests from a recorder or plain English. If that is the workflow you want, Diffy does not do it.
• Enterprise controls. Applitools offers dedicated cloud, SSO/SAML, on-premises deployment and custom SLAs on its higher tiers.

Drupal and WordPress experts

We know a lot about Drupal and WordPress hosting environments and development workflows — it is why Diffy ships login presets for both, and why the CLI documentation has worked examples for Pantheon and Tugboat. If that is your stack, we will make sure you get a reliable testing setup, and you can talk to the people who built Diffy when something looks wrong.
