GitHub Hovercard v0.3.3

GitHub Hovercard v0.3.3 launched on December 26, 2015 with 40 votes, #1,726 of 3,505 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 10 years on.

In plain words

GitHub Hovercard is a browser extension that displays popup cards with instant user, repository, issue, and commit information when hovering over GitHub links. Built for developers working on GitHub, the tool reduces navigation by showing relevant details directly from any page on the site. The extension is available for download from its GitHub repository, with manual installation options for Edge and Safari while store availability is being established.

GitHub Hovercard is a third party tool which is not affiliated to GitHub (github.com). This page is designed exactly the same as GitHub only to show how the extension actually works on GitHub.

  • Hover – IDE style hover documentation on any webpageJan 2026 · github.com · ▲58

    I thought it would be interesting to have ID style hover docs outside the IDE. Hover is a Chrome extension that gives you IDE style hover tooltips on any webpage: documentation sites, ChatGPT, Claude, etc. How it works: - When a code block comes into view, the extension detects tokens and sends the code to an LLM (via OpenRouter or custom endpoint) - The LLM generates documentation for tokens worth documenting, which gets cached - On hover, the cached documentation is displayed instantly A few things I wanted to get right: - Website permissions are granular and use Chrome's permission…

It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
