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.
TestMu AI
TestMu AI is a platform for quality engineering across web, mobile, and AI applications. Its AI agents can plan, write, run, analyze, and optimize tests. The service also supports automated execution, visual comparison, real-device testing, and local testing. Teams can connect it to tools including Jira, Azure DevOps, GitHub, Jenkins, GitLab CI, Slack, and Microsoft Teams. REST APIs cover test management, execution, and artifact retrieval; webhooks provide event notifications. It can be deployed as SaaS cloud, private cloud, or on-premise. Test execution can run air-gapped, but AI-agent features need connectivity to TestMu AI APIs. The default retention period is 60 days; Enterprise customers can arrange custom retention. TestMu AI lists a free plan and paid pricing from $15/mo (annual). Its named KaneAI plans are billed annually: Starter is $17 a month, Pro is $89 a month, and Max is $179 a month. Enterprise pricing is custom. The company says LambdaTest evolved into TestMu AI on January 12, 2026.
