On QuickQ we went the other way: one button, and the client decides. This post is about the trade-offs behind that decision — the parts that are easy to get wrong when the app has to behave the same on Windows, macOS, iOS, Android and Ubuntu Linux.</p> <h2> Why one button </h2> <p>The first-run problem is not "which node is faster". It is "I do not know what any of these words mean". A single primary action removes that wall: open the app, press connect, get a working state. Everything else — protocol, route, fallback — is a detail the client can decide and expose only if the user asks.</p> <p>The cost is that the client now owns error handling. If the automatic pick fails, you cannot tell the user "you picked the wrong node". You have to retry a different route, and you have to say what is happening while you do it.</p> <h2> Route selection needs a fallback, not a winner </h2> <p>A common mistake is treating route selection as a ranking problem: measure candidates, take the best one, done. In practice the best candidate changes every few minutes, and a route that measured well from one network can be unusable from another.</p> <p>What worked better was treating selection as a short ladder: try the current best, move to the next candidate on timeout, and only surface a choice to the user when the whole ladder fails. From v4.0 the client also exposes manual line selection and a live latency readout for people who want to override it — but the default path stays automatic.</p> <h2> Keep the state visible, not the plumbing </h2> <p>A connect button that does not show progress feels broken. Three signals covered almost every case for us: connection state, the current route, and latency. They are cheap to show and they answer the only question a user has — "is it working right now?"</p> <p>Everything else (protocol, handshake details, logs) stays out of the main view. If you are building something similar, resist the urge to put a protocol picker on the first screen: it is the least useful control for the majority of users and the most likely to be left in a bad state.</p> <h2> What we would tell someone building the same thing </h2> <ol> <li>Make the happy path a single action, and spend your error budget on automatic fallbacks.</li> <li>Show state and latency before you show settings.</li> <li>Keep the same interaction on every platform — a mobile client that behaves differently from the desktop one doubles the support surface.</li> <li>Decide early how many devices one account can keep online; it shapes the account model and the support stories.</li> </ol> <p>The client we ended up with runs on Windows, macOS, iOS, Android and Ubuntu Linux, with up to 3 devices online per account.
