mkpl.com is a collection of Chrome extensions positioned around “Productivity & Savings.” The current site lists three products: UX Replay, Marketplace Monitor, and Universal Dark Mode. It covers developer debugging, second-hand marketplace monitoring, and everyday browsing improvements, with an emphasis on being free, privacy-first, open source, and tracking-free.
UX Replay is built for web debugging, offering session replay, console logs/errors, network request tracking, and shareable links. The Pro plan adds GPT-4-powered AI bug reports, team sharing, 30-day retention, and advanced filtering. Marketplace Monitor tracks Facebook Marketplace, Kijiji, and Craigslist, with filters for keywords, cities, and platforms, plus browser push notifications and Telegram alerts. Universal Dark Mode provides one-click dark mode for any website, auto-enable, color schemes, brightness and contrast controls, keyboard shortcuts, and offline use. Its ecosystem mainly relies on Chrome, Telegram, OpenAI/GPT-4, rrweb, and GitHub.
The site clearly emphasizes that the extensions run locally, with no tracking, no ads, and no third-party analytics, keeping data on the device whenever possible. The terms state that “many of our extensions” use the MIT License and can be viewed, modified, and forked, but they do not list the repository status for each extension individually. For self-hosting, only UX Replay Enterprise explicitly offers an on-premise deployment option, including SSO/SAML, custom retention, dedicated support, and an SLA.
Pricing is fairly clear: UX Replay’s free tier includes 5 sessions per month, while Pro costs $9/month; Marketplace Monitor’s free tier supports a limited number of keywords and cities, Pro costs $4.99/month, and Business costs $19.99/month; Universal Dark Mode is completely free. All extensions include a free tier and require no credit card, while paid plans come with a 30-day refund policy. The setup and usage flow for Marketplace Monitor is described in relatively complete detail, and users should be able to get started within minutes.
The main advantages are low entry cost, a clear privacy-focused narrative, and focused functionality. UX Replay is valuable for frontend teams trying to reproduce issues remotely, while Marketplace Monitor is practical for frequent users of trading platforms. The downsides are that the current format is limited to Chrome extensions; Marketplace Monitor’s free mode depends on the browser staying open; documentation mainly covers Marketplace Monitor, with fewer details for the other products; payment methods and code activity are not disclosed; and some descriptions of free usage limits appear inconsistent.
The site does not provide information about access, payment, or compliance in mainland China, so this remains unknown. If Chrome Web Store, Telegram, or OpenAI-related capabilities are unavailable, the actual user experience may be affected. Comparable alternatives include Sentry Session Replay, LogRocket, Microsoft Clarity, Dark Reader, and various marketplace alert tools.
