Custom-builtApps built by Klair

No app fits your case? We build it.

Klair builds your own app, from a specification written with you, from the first message to going live.

See what you pay

« Describe my project » opens a conversation with Klair, which helps you write the brief.

Your project, in four steps.

From the first message to the delivered app, you know where you stand.

  1. Describe your need

    In your own words, in one conversation with Klair, with no form and no blank page. A first brief takes shape in front of you.

  2. The specification

    Written together, before you commit to anything. It says what the app will do; we also question the process with you before setting it.

  3. A firm quote

    Klair prices the specification and splits the work into milestones. You sign if the quote suits you.

  4. Your app, delivered

    Built milestone by milestone, followed in your Klair space, then accepted with you.

Going live comes next, along the path you choose.

What belongs to you.

  • The code

    Handed over at acceptance. Its rights are assigned to you as soon as the project is paid in full.

  • Your data

    It stays your organisation's. If you leave, it is returned to you in an open format.

  • The specification

    Written with you, it is yours. It describes what the app will do, in plain language.

A firm price, paid milestone by milestone.

The price
Set once, on the specification. No day rate, no time and materials.
The milestones
The quote splits the price into milestones, each with its content and its amount. You pay one milestone at a time.
When
Each milestone is paid at its acceptance; the next one starts once the previous one is settled.

After delivery, two paths.

At acceptance, you choose who runs your app.

You leave with everything

You install the app wherever you like, on your premises or with a host, and your team or the provider of your choice runs it.

The handover file

  • The source code
  • The architecture documentation
  • The deployment guide
  • The inventory of third-party services

Klair hosts it

Klair runs your app on its platform. You choose the size in the quote; billing starts when it goes live.

In every size: every new version put online, a secure address (HTTPS), sign-in with the Klair account, the platform's security updates, backups kept 30 days and restored on request.

Custom: a size plus lines from the published grid, on quote. If the app outgrows its size, Klair tells you and offers the next one.

Operations, as an option

€150excl. VAT per month at least, or 1% of the project's price if that is more

  • Continuous monitoring
  • Incident triage and fixes
  • Security and component updates
  • Two small changes a month

A Klair agent makes the first pass; the team steps in during business hours. Each release is approved by Klair, or by you if you prefer. Neither hosting nor operations carries a numbered availability commitment (no SLA). Operations is reserved for projects built and hosted by Klair.

Once live, your app appears in your space as a private app, next to Agora and Promoimo. No price and no paid seat: hosting covers it.

  • Promoimo

Before you describe your project

How long does it take?

The timeline depends on the specification: each milestone has its date, written in the quote before you sign.

What if our need changes along the way?

You ask for the change; it is priced in an amendment, and nothing is committed until you accept it. Without an amendment, the quote's price does not move.

What if the app does not do what was planned?

Acceptance is done point by point against the specification. For 90 days after that, any gap with it is fixed at no cost; while operations runs, its ongoing fixes take over.

Can we leave hosting later?

Yes. Hosting and operations end with one month's notice, with no minimum term. You then take the other path, with the code, the handover file and your data.

Tell it in your own words; Klair helps you turn it into a brief.
