So here's one: <strong><a href="https://github.com/dariush624/isdown" rel="noopener noreferrer">isdown</a></strong> — a little CLI that checks if services like GitHub, Slack, AWS, or Cloudflare are having issues.<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code><span class="nv">$ </span>isdown check github slack GitHub: Up Slack: Degraded · Slow API <span class="o">(</span>investigating<span class="o">)</span> </code></pre> </div> <p>It just queries each service's public status endpoint — no API keys or setup. You can also pass any URL, or add <code>--json</code> for scripting.<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code>cargo <span class="nb">install</span> <span class="nt">--path</span> <span class="nb">.</span> </code></pre> </div> <p>It's nothing groundbreaking, but it gave me a reason to actually use <code>clap</code>, <code>reqwest</code>, async, and a bit of macro magic for the provider registry. I learned a lot, and I'm sure there's plenty I got wrong.</p> <p>Repo: <strong><a href="https://github.com/dariush624/isdown" rel="noopener noreferrer">https://github.com/dariush624/isdown</a></strong></p> <p>If you spot something that could be better, I'd genuinely love the feedback — issues and PRs are very welcome. 🙏</p> rust cli learning opensource
