Chief Product Officer of Fastmail here. I see a lot of comments here from people that don't appear to have actually tried using the app, which is a little disappointing; don't knock it 'til you've tried it! Happy to answer any questions, but to answer the main ones that are popping up:

# Why Electron?

Because it lets us build an app that works well across all major platforms with the resources we have available. Building an email/contacts/calendar app is a huge undertaking. Doing it from scratch on each platform is just not feasible for us.

With Electron, we can maintain a single code base across all platforms so we can move faster, and keep feature parity everywhere. More than that though, we believe it lets us build a really great experience on each of these platforms, while offering a consistent UI for our customers across all their devices. Honestly, we can never out-native Apple because by definition whatever they do is "native", even if it sucks (Liquid Glass on the Mac is … not great UX). If that's your primary consideration, you will always be better with Apple's own Mail app, so it's pointless us trying to build something in that space. (And instead we work to also make Fastmail the best service to use Mail.app with — which we believe it is!)

# Why would you use this instead of the webmail?

If you prefer to keep Fastmail in your browser, great! You can do so. But we hear from many customers that they would rather not have their email mixed in with their tabs. With a separate app you can see it in the dock, Cmd-tab to it, make it your default email app system wide etc. It also lets us integrate with the system, like the Mac menu bar and native context menus.

# Why would you use this instead of an IMAP client?

If you've ever used the Fastmail web interface you probably already know the answer, but for everyone else…

1. It's a lot faster. Compared to Apple's Mail.app for example (which is a good IMAP client!):

   - It resyncs way faster when you open the app, and uses a lot less data (JMAP is so much more efficient).
   - Moving between messages is quicker. With Mail.app there's often a slight lag between clicking a message and it rendering. In Fastmail, it's usually instant.
2. It's more powerful. We provide the best standards support out there, and are also working to make the standards better. But there's always going to be more that we can do when we control both the server and the client. With the Fastmail UI you can:

  - Add private memos to emails
  - Mute conversations to ignore replies
  - Pin important messages to the top of your inbox
  - Schedule messages to send in the future (and not need your laptop to be online then for it to work)
  - See related emails when you open your contacts.
  - Add events straight into your calendar
  - And much more (https://www.fastmail.com/features/).
3. It's got much better search. (Yeah, this is kind-of just "more powerful", but I'm calling it out because search sucks in most email clients0.

# And finally…

This is just a choice. We hope this is something that some of our customers will love, but we're not backing away from our commitment to open standards and encourage everyone to find what works best for them.

I'll try to answer any other questions as I can.

Windows

Each story opens in a window holding its article above its discussion; drag the bar between them to share the room differently. A window can be moved by its title bar, resized from any edge, snapped to a half or a corner by dragging it there, maximised, or minimised to the bar at the foot of the page. Use Window > New reader window to open an empty reader, or Story > Open in new reader window to open another reader for the current article. Docked readers keep their articles when you select another story from the sidebar. Minimized readers can be restored and reused for their site. A window's Previous and Next buttons read up and down the list in the same window.

A link in a comment or an article to another Hacker News or Lobsters thread opens that thread in a window too. A link to a single HN comment opens the comment above its replies.

While a story's window is in front, the Story and Discussion menus in the menu bar hold its commands: pinning, Previous and Next story, sorting, collapsing every thread, jumping to the first new comment. Each window also remembers where you were in its article and discussion, so a reload, or Back to a story that Next took you past, finds your place again. Closing a window forgets it.

The whole arrangement lives in the address, so a bookmark or a shared link brings it back, and Back undoes the last change. Moving between Hacker News, Lobsters, their lists, Pinned and Find changes only the list, and leaves the windows open.

The list

The pin at the start of a row keeps the story in Pinned, and the cross at its end hides it. Pinned can be narrowed by words in the title, site or author, by source, and to the stories you haven't opened yet, and ordered by when you pinned them, by points or by comments; the filters are part of the address, so a filtered view can be bookmarked. Scroll past the end of the list to load more. Domain filters, in the View menu, hide every story from a site.

Collections are named lists of stories. Story > Add to collection files the story in front into one or more of them, and the Collections feed shows them all or one at a time; the menu that chooses collections also creates, renames, and deletes them. A note is your own text on a story. Choose Add note in a story's toolbar to write one; it saves as you type. Rows with a note carry the note mark, and the Notes feed lists every noted story and searches the text of your notes.

Browsing view

View > Windowed and View > Classic select the browsing view and save your default in this browser. Window view reuses a reader for each feed. Classic view opens stories and applets as pages. Open as a page is a one-off action that does not change your saved default. Use the Windowed selector to return an article to a window. Direct page links always open as pages.

Applets

The Applets menu in the menu bar holds three tools, each a window of its own. Replies to me takes your Hacker News user name and lists the replies to your last thirty comments and stories, checking again every three minutes while it is open, and marking what is new since you last marked them read. Look up a user opens a profile on Hacker News or Lobsters, with their submissions and recent comments, as a commenter's name in any discussion does; the bar at the top of a profile looks up someone else in the same window, and Back returns to the one before. Who is hiring? filters the posts of HN's monthly hiring threads by the words you type.

They read only what the sites publish to everyone, so none of them asks for a login, and your user name stays in this browser anonymously and is included in retained applet state when signed in.

Find

Find takes any link and lists every time it was submitted to Hacker News and Lobsters, so you can read each discussion of it.

About

YAVCHN never sees your Hacker News or Lobsters login. The discussion is fetched from each site's public API; to vote or reply, follow the link above the discussion, or the arrow beside a comment, to the source's own site. Without a YAVCHN account, your data stays in this browser. When signed in, pins, collections, notes, blocked domains, and retained reading state are stored with your account and synchronized across devices. Hidden stories and layout stay in this browser. The privacy policy has the details.
