In their own words
Browserling
Browserling provides cloud-hosted virtual browsers for checking websites and links across browsers and operating systems. Its listed browser coverage includes Chrome, Firefox, Safari, Edge, Opera, and Internet Explorer on real operating systems, as well as mobile browsers on Android and iOS devices, including iPhones and iPads. Users can inspect pages at different screen sizes, resolutions, and device viewports. SSH tunnels provide access to private or local development sites. Other listed tools include screenshots, file uploads and downloads, geo-browsing, browser extensions, and bookmarklets. A free sandbox opens a URL in a remote isolated browser session. The Live API can embed interactive browsers in applications and supports automation, continuous integration, and SIEM/SOAR workflows. Browserling says each session runs in an isolated virtual machine that is destroyed afterward; traffic uses TLS 1.2 or higher, and URLs, session content, and files are not persistently retained. Paid plans begin at $9 a month billed annually. Listed options include Starter at $9 a month billed annually, Developer at $19 a month billed annually, and Live API at $99 a month as a starting price.
Happo
Happo checks interface changes with visual and accessibility regression testing. It captures screenshots of component variants in browsers; a snapshot is one variant in one browser, and a run usually occurs once per CI build. Accessibility testing is included on every plan. Framework options include Storybook, Playwright, Cypress, and a generic API. Repository integrations include GitHub, GitHub Enterprise, Bitbucket, Azure DevOps, and GitLab, though GitLab support is experimental. Its CLI detects CI providers such as GitHub Actions, CircleCI, Travis CI, and Azure DevOps. Available browsers vary by plan: the listed options are Chrome, Firefox, Safari, Microsoft Edge, and iOS Safari. The free plan includes 5,000 snapshots per month; once the quota is reached, the account pauses until the next cycle or an upgrade. Paid plans start at $149/mo, with additional snapshots charged on paid tiers. Happo began as a project in 2014, and its commercial product launched in 2017.
