Everything Quavern makes, behind one free account

You already have too many accounts. Here is the argument for one more, and then for a few less.

One sign-in, four products, no second registration

Marl, the assistant. Marl Code, in your terminal. Quavsit, real-time transit. Quavblok, the Minecraft network. QuavernOS. The MCP server.

Sign in once on my.quavern.com and every one of them knows you. No separate registration anywhere, no "create an account to continue" behind the next thing we build. That is a promise about the future, not a feature of today.

It is free. Not a trial, not a tier — the account itself costs nothing and always will.

What you can actually do with it today

Put live departures on a screen. Quavsit boards turn any display into a platform indicator: the hallway of an office, a café window, a school entrance. You build it in the browser, you point a screen at it, it runs.

Put them on your website. The embeddable widget is a snippet of HTML. Your visitors see the next trains from the stop outside your door, updating themselves, without you writing a line of code.

Get told when a network breaks. Feed watches write to you when a transit operator's data stops arriving — before your board goes blank and somebody asks you why.

Have an assistant that remembers. Marl keeps what matters between conversations, and you can read that memory, correct it, or empty it. It is yours, visible, and editable — not a black box that has quietly formed opinions about you.

Link your Minecraft player to your Quavern account, and carry your settings between sessions.

Build on the API. Personal keys, a usage page that shows exactly what you have spent, and plans from free upward.

And one thing, shipped today, that asks for nothing at all

Every stop page, every line page and the alerts page on Quavsit now carries a control that asks Marl what is happening there. Press it and you get one paragraph: which lines are late and by how much, what is interrupted and until when.

No account. No sign-in. No trial. We built it and we left it in the open, because somebody standing on a platform in front of eleven departures should not have to register to be told, in a sentence, that line 4 is running two minutes late.

The facts it was written from are listed directly underneath, so every number can be checked against the board you have just read. Marl never invents a cause, nor a resumption time the operator has not published, nor reassurance it has no way to keep. A wrong summary is worse than no summary: this is transport, and people miss connections on it.

That is the "no create an account to continue" promise above, with a date on it.

The part nobody else offers

Nothing here follows you. quavern.com loads no third-party script and carries no advertising or marketing tracker. The applications offer one optional measurement — how fast pages load — off until you switch it on, and refusing it changes nothing.

Deleting means deleting. Press the button and the conversations, the memory, the keys, the boards are gone. Not archived. Not a flag on a row that stays in a table forever.

You are not a profile. No interest graph, no score, nothing inferred about you and sold. We hold what you gave us and what the service needed to run.

And it is properly locked. A passkey, so there is no password to lose. Or an authenticator app. Recovery codes either way. A phone number is a fallback and never a way around a stronger factor — if you hold a passkey, an SMS code will not open the door. When your account is used from a device we have not seen, you get a note saying when, roughly where, and on what.

Why this is the account worth keeping

Products come and go. Quavsit did not exist a year ago. Quavblok did not exist six months ago. What survives them is the identity you use to reach them, and how much say you have over what it remembers.

One account. One place to delete it from. Nothing sold, nothing tracked, nothing waiting behind the next door.

Create yours at my.quavern.com. It takes a minute, and it is the last Quavern account you will ever need.
