About
99tests is a crowdsourced, fixed-price testing service for mobile apps and websites. Teams upload a build or URL, provide test cases—including AI-generated cases—and choose device and browser targets. Testers in India run the cases on their own phones, laptops, and browsers. 99tests returns a human-verified report with pass/fail results, reproduction steps, expected and actual behavior, device and OS details, and screenshots or recordings for findings. Its hosted workflow also supports an MCP server that compatible coding clients can use to look up packages, create jobs, check status, and retrieve reports; payment is completed through browser checkout. Teams use 99tests for release checks and regression testing across real devices without maintaining an in-house device lab or QA team. Fixed-price packages specify session, device or browser, and test-case limits, along with turnaround times. 99tests also offers separate free online QA utilities.

About
Preveo is a browser-based website evaluation tool for developers, designers, freelancers, agencies, and product teams preparing sites for release or client review. Its browser extension helps examine a website or local development page through ready-made checks and reusable macros. Evaluations cover user experience, layout, SEO, accessibility, performance, content, and visibility to AI assistants. Users can review responsive behavior across screen sizes and test selected browser, device, theme, language, and text-direction variations. Reports can include screenshots, recordings, performance data, network failures, and console errors, helping teams document issues, compare changes, and plan improvements. Preveo complements website builders and coding tools, including AI-assisted development platforms, rather than replacing them. It supports teams using modern frontend tools and people reviewing websites for clients.
