Plausible provides privacy-first web analytics through a lightweight script and a focused, single-page dashboard. It measures traffic and events without cookies, persistent identifiers, stored IP addresses, or personal profiles, which can reduce consent and compliance overhead for many sites. Users can choose the paid managed cloud service for a maintained setup or deploy the free Community Edition themselves. Self-hosting offers control but leaves infrastructure, security, backups, and upgrades to the operator.

Livebook lets teams write Markdown and Elixir code cells together in a browser, then run queries, charts, and other data tasks on demand. Notebooks are stored as versionable .livemd files and can connect to a fresh runtime, an existing Elixir node, or a project. Because users can execute code and access files on the host, deployed instances should be carefully protected.

Litlyx helps websites and web apps collect visits, real-time users, and custom events through a small script tag or JavaScript package. Data is viewed in its analytics dashboard, with a hosted service available for quick setup or Docker deployment for teams that want to run their own instance. Its cookie-free approach makes it a practical option for projects seeking straightforward analytics without committing entirely to a third-party cloud.

AI Hot Monitor is a hands-on teaching project built around a working trend-tracking application. Users define keywords, aggregate results from more than eight sources including Twitter, Bing, Hacker News, and Bilibili, then apply AI query expansion, authenticity checks, relevance scoring, and summaries. Results can be filtered and pushed through WebSockets or email, and the monitoring workflow is also packaged as an agent skill; the repository is primarily presented as a build-from-scratch course project rather than a hosted service.
