What native buys, concretely
“Native” is used as a marketing word often enough to have stopped meaning much. Three things it actually changes.
- Startup and memory. An Electron app loads Chromium before it draws the first conversation. On a laptop with three other Electron apps open, this is not a theoretical cost.
- System behaviour for free. Text substitution, the services menu, keyboard navigation, the share sheet, Spotlight, the system text engine. A native app gets these because macOS provides them. A web app has them if someone reimplemented them, and usually only partly.
- Offline.A web app in a window is a web app. Moorline’s database is a local file, backed up hourly and kept for a week, so a flight with no wifi is an ordinary working session.
And what it does not buy: features. Front and Missive have far more of them than Moorline does, and if collaborative drafting is what you need, Electron is a rounding error against having the feature at all.
The Apple Mail question
Apple Mail is native, free, already installed, and genuinely fine for low support volume. It has the same blind spot as Gmail and every other mail client: it has no idea a customer is still owed a reply. You archive the thread to work on the problem, and from that moment it is indistinguishable from a conversation that ended well.
That is the specific gap Moorline fills, which is why it reads your mailbox rather than replacing it. Apple Mail keeps working exactly as it does today.
Questions people actually ask
Is there a native Mac customer support app?
Almost none. Front and Missive ship Electron desktop apps, which are the web interface in a window. Help Scout, Zendesk and Freshdesk are browser-only. Moorline is written in Swift against macOS itself, which is why it can work offline and keep its data in a file on your disk.
Does it matter whether a support app is native?
It matters for three things: launch time and memory, whether system behaviours like text substitution and keyboard navigation work without being reimplemented, and whether the app functions with no network. If you live in a browser all day anyway, it matters less than the feature set does.
Can I use Apple Mail as a support desk?
You can, and for low volume it is fine. It has the same blind spot as every mail client: an archived thread you are still working on looks identical to one that is genuinely finished, so a fix you forget to announce is invisible.
Which support apps work with iCloud or Fastmail?
Any tool that connects over IMAP rather than asking you to forward mail into their system. That is Missive, Front and Moorline on this list. Help Scout, Zendesk and Freshdesk want your support address pointed at them instead.
