THE WHOLE IDEA

One small app
that fixes
one thing.

Not a product. Not a platform. Not a project with a roadmap and a kick-off. Something that was in your way on Tuesday, running on Tuesday afternoon.

ENTRY 01 saasie.io

saasie

/ˈsæs.i/ · noun

  1. 1.

    A small web app, built by a code agent because somebody asked for it, that solves one imminent problem.

  2. 2.

    The app you wish existed — the one nobody was ever going to build for a group of five.

From SaaS, made small. Software as a service, for a service of exactly one.

Make one: every book you own

One problem One app Live on the web Yours to change

THE SHAPE OF IT

Four things
make it a Saasie.

01

It starts with something imminent

Not a nice-to-have you will get around to. A thing that is in the way today — the spreadsheet nobody can edit at once, the sign-up sheet on the fridge, the four people asking you the same question every week. Saasies come from irritation, not from strategy.

02

It does one job

A Saasie has no settings page, no plans, and nothing in it that somebody else asked for. It is small because small is what makes it finishable — and because the second job is a second Saasie, which costs you another sentence rather than another release.

03

It is on the web straight away

Every Saasie gets its own address — yourthing.saasie.app — and that address answers from the moment the name is claimed. There is no staging step and no preview to graduate from. What your agent builds is the thing that is running.

04

It is yours to change

You ask for the next version in the same plain language you asked for the first. No tickets, no versions to plan, no release notes. The app changes because you said so, and it is live again a few minutes later.

NONE OF YOUR BUSINESS

The whole software
industry, skipped.

Everything below exists, and your Saasie uses all of it. You are simply never the one holding it.

What we ask of you is an email address, and a code from your inbox once. That is the entire list.

AND THEN?

Small is where
it starts.

Plenty of Saasies stay one screen forever, and that is a success. But nothing about being small is a ceiling — a Saasie that keeps proving useful gets asked for more, and grows into the thing you actually run on.

  1. 01

    One problem, one app

    You describe the thing that is annoying you. A code agent builds it, deploys it, and gives you the URL. Nothing about this stage is an investment — if it turns out to be wrong, you switch it off, and an afternoon is all it cost you.

  2. 02

    It earns its place, or it doesn’t

    Some Saasies are opened once. Others quietly become the way something gets done. You find out by using it, which is faster and more honest than deciding in advance.

  3. 03

    You ask for the next thing

    The operator — whoever owns the Saasie — asks for changes in plain language, and the agent makes them. Add the bit you realised you needed. Fix the bit that annoys everybody. Each request is another push, not another project.

  4. 04

    It becomes a real application

    Enough of those, and the small thing is not small any more. It has users, a shape, and a job in your week. It got there by being useful at every step, which is not how most software is built.

WORTH BEING PLAIN ABOUT

What a Saasie
is not.

It is not a no-code builder
There are no blocks to drag and no canvas to learn. A Saasie is real code, in a real repository, written by a code agent. You just never open it.
It is not an app inside somebody’s app
It is not a page in a workspace tool or a tab in a suite. It is a web application at its own address, which is why you can send the link to anybody.
It is not a prototype
Nothing here is a mock-up you later have to build properly. The deployed Saasie is the deliverable, from the first version onwards.
It is not forever
A Saasie that stops being useful should be switched off, and that is a feature. Small apps are cheap to make, cheap to keep, and — unusually — cheap to stop.
