Deliver client apps in days, with code you can hand over.

Turn a client brief into a working app you can click through in the first meeting. Keep shaping it by chat or by editing the code yourself, publish it on the client's domain, and hand over a GitHub repository at the end.

One prompt: a client portal for an accounting firm.

What you write
A client portal for an accounting firm. Clients sign in, upload receipts and documents as PDF or photos, and see the status of their tax return. Staff see every client, change the status, and leave notes only staff can read.
Build this example

What Crisp builds from it

  • Separate sign-in for clients and staff, with staff-only notes
  • Document uploads for PDF and image files, kept with the app
  • A status for each client's return that staff can change
  • A client home page that shows only their own documents
  • A staff page with every client and a search

Then it opens the app in a real browser, tests it, and fixes what fails before it says it is done. How a build works.

Fast to start, nothing to lock you in.

The first version comes from the brief in minutes, so the meeting is about the real app, not a mockup. The code is ordinary and readable: edit it in the Code tab, sync it to GitHub, and hand it over or run it anywhere.

How it works.

  1. Step 1

    Describe it

    Write what you want in plain words: who uses it, what they do, and what matters most.

  2. Step 2

    Watch it being built

    A first look appears within about half a minute. Then the data, the forms and the other pages, each one tested.

  3. Step 3

    Publish it

    Give it its own address when you are happy with it. Keep improving it; people see changes when you publish again.

What you get.

Good to know before you start.

  • The cleanest hand-over is the GitHub repository: the client gets the full code and can run it anywhere, with or without Crisp.
  • The security check finds common problems, not every one. For client apps with sensitive data, add your own review.
  • Crisp does not offer a white-label version of the builder itself. The apps you build carry the client's brand, not Crisp's.

Questions.

Can I bill clients for apps I build with Crisp?

Yes. You own what you build, including the code, and you can sell your work on it.

Can I use my own code editor?

Yes. Sync the project to GitHub, work locally, push, and pull the changes back into Crisp.

Can I plan the work with the client first?

Yes. Plan mode writes a plan of the pages, the data and the look that you can edit together before anything is built.

How do I show a client the app before it is live?

Publish it to its Crisp address and share the link. Keep building: the client sees changes only when you publish again.
