About
You can interact with the browsers live as if they were installed on your computer. We run real desktop browsers on our servers in virtual machines. We don't use emulators or fake browsers. We install the latest browsers as soon as they come out. You get online access to the latest browsers instantly. You can capture, save, and share screenshots of your web pages in all browsers. You can also annotate them and send bug reports this way. Change screen resolution and resize browsers for all your responsive testing needs. All connections between you and Browserling are SSL encrypted. Your browsing is completely anonymous! Browserling is powered by HTML5 and JavaScript. You don't need to install anything. It just works.

About
Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability.
Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort.
Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in.
Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens.
The result: ship faster, with confidence.
