If you mean checking your own app’s UI for unintended visual changes, compare Percy, Chromatic, and Applitools Eyes with Loki. If you mean watching a live public webpage for changes and alerts, that is a different job: Visualping and Wachete describe that kind of monitoring. Choose by workflow rather than treating these tools as interchangeable.
Here, “Loki” refers to the free Storybook screenshot tool for visual checks of web, iOS, and Android interfaces, as described by iTechGuides. That listing says Loki lacks cross-browser capture; it is a third-party directory description, not Loki project documentation. The phrase “monitor website changes” can also mean tracking pages you do not control, so the two paths below are separated.
First decide what you need to monitor
Visual regression testing for your own product
Use this path if you want to compare screenshots of your application’s interface across builds, typically as part of development and release review. The relevant shortlist in iTechGuides’ alternatives listing is Percy, Chromatic, and Applitools Eyes. Compare browser coverage, CI/CD integration, approval workflow, and plan fit. The listing’s rankings, scores, and prices are that publisher’s editorial snapshot—not independent test results or guaranteed current vendor terms. Check vendors’ current documentation and plans before choosing.

Pick the symptom - the matching free tool is one click away.
Change alerts for public webpages
Use this path if you want a service to check a live page on a schedule and notify you when its content changes. Visualping and Wachete describe this category. The useful questions are whether checks run in the cloud or locally, how often they can run, whether you can target a page region, whether dynamic or login-protected pages are supported, which alerts and history are available, and what the current price is.

Shortlist for visual-regression testing
Percy, Chromatic, and Applitools Eyes are named as Loki alternatives in iTechGuides’ current alternatives listing. The evidence available here does not establish a verified, like-for-like feature or price comparison among them, so treat them as candidates to evaluate rather than as tested winners.
| Candidate | What to verify before adopting |
|---|---|
| Percy | Browser coverage, CI/CD integration, review and approval workflow, and current plan terms. Specific current details are not established here. |
| Chromatic | Browser coverage, CI/CD integration, review and approval workflow, and current plan terms. Specific current details are not established here. |
| Applitools Eyes | Browser coverage, CI/CD integration, review and approval workflow, and current plan terms. Specific current details are not established here. |
To make a fair selection, run the same representative UI changes through each candidate and check how screenshots are captured, how diffs are reviewed, and how approvals fit your team’s release process. Confirm support for your framework and CI environment directly with each vendor; the available listing does not establish those details.

Shortlist for live webpage monitoring
| Service | Documented capabilities | Check directly before choosing |
|---|---|---|
| Visualping | Scheduled checks of a whole page or selected element; visual, text, and code change detection; before-and-after comparisons. | Available check intervals, alert channels, history limits, login handling, current plan prices, and India billing terms. |
| Wachete | Monitoring while your devices are off; selected areas, dynamic and login-protected pages, linked pages, and files. Its listed use cases include price tracking, competitor watching, unexpected-change detection, availability checks, change history, and job alerts. | Available check intervals, alert channels, history limits, current plan prices, and India billing terms. |
These descriptions come from the services’ feature and use-case pages; they do not establish a controlled comparison of reliability, detection accuracy, or speed. If a page changes frequently for irrelevant reasons, prioritize region selection and the ability to distinguish meaningful text or visual changes. For login-protected or dynamic pages, confirm the exact supported workflow before subscribing.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteWhat Indian buyers should verify
The available information does not establish which services currently sell to Indian customers, their India-specific taxes or billing treatment, or where monitored data is stored. Confirm availability, currency and tax details, payment options, and data-location terms with each vendor before purchase. Do not treat a third-party price snapshot as a current India price.

ScreenshotNeo: an alternative to try first for screenshot capture
If your actual need is to request clean screenshots programmatically—not to compare builds in a visual-regression review flow or receive scheduled change alerts—try ScreenshotNeo. It is a website screenshot API and MCP server for developers, with a one-request URL capture. Cookie and consent banners, newsletter popups, and chat widgets are removed before capture, and those steps can be disabled. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed; responses identify the page verdict and billing status in headers. Its MCP server includes tools for AI agents, including Claude, Cursor, or another MCP client. It is a screenshot-capture alternative, not a substitute for a scheduled webpage-change alert service.
Plans include 1,000 screenshots per month free with no card, then paid tiers starting at $5 for 3,000 screenshots; every feature is available on every plan. See the ScreenshotNeo documentation for request options.
