Software studio · Commissions open

Small software that does one job, properly.

CanvasAndCell builds custom interactive tools — calculators, trackers, quizzes, planners, intake forms — and delivers them as a single file you own outright. No account to create. No server to rent. No monthly fee. Open it in a browser and it works, including on a plane.

  • 29 finished apps in the current catalog
  • One HTML file per build
  • Works offline
  • Tested in a real browser before you see it
A dark money dashboard showing a monthly spending total, a category breakdown with progress bars, and a spending trend chart.
Budget & Money Tracker. Live category budgets, debt payoff math, recurring subscriptions.
A wedding seating chart with round tables laid out on a grid, one table outlined in red, and a warnings panel listing a keep-apart clash.
Wedding Planning Suite. A seating chart that flags capacity and keep-apart conflicts as you drag.
An evidence room screen from a detective game showing twelve document cards in a grid, several marked as read and two flagged.
The Glass House Case. Twelve cross-referenced documents, five suspects, one accusation screen.

What gets built

Four kinds of work, in priority order

Every one of these ships the same way: a single self-contained file, tested end to end, yours to keep, host, copy and change forever.

Custom interactive tools

The thing your business explains over and over, turned into something a customer can use themselves. Quote calculators, dose and dosage trackers, symptom journals, progress dashboards, intake and triage forms, session planners.

  • Small businesses, coaches, tutors, therapists, clinics
  • Runs on your site, or as a file you email to a client
  • Client data stays on the client's own device unless you ask otherwise
How this works

Party games & event experiences

Custom escape rooms, murder mysteries and party games written around real people, real venues and real in-jokes. Three working engines already exist, so a commission is writing and puzzle design, not rebuilding the machinery.

  • Weddings, birthdays, corporate away-days, hen and stag nights
  • Answers are checked by the app — no answer key for someone to peek at
  • Staged hints, a countdown, and a printable pack if you want paper
How this works

One-page business sites

A fast single-page site that loads instantly, costs nothing to host, and does not stop working when a subscription lapses. You get the source. Move it anywhere, change it yourself, or never touch it again.

  • No platform lock-in and no recurring platform fee
  • Hosts free on Netlify, Cloudflare Pages or GitHub Pages
  • Built to score well on speed and accessibility, not just look fine
How this works

Digital products for other sellers

White-label interactive products for shops that sell templates and printables. You brand it, price it and sell it as your own. Most template shops sell PDFs; an app that actually saves the buyer's typing is a different listing entirely.

  • Your colors, your fonts, your name in the file
  • Delivered with a buyer-facing setup guide you can rebrand
  • Exclusive or non-exclusive licensing, agreed in writing up front
How this works

Try it yourself

Three demos, built for this site

These are not the products in the catalog — those are for sale, and giving them away would be daft. These three were written specifically as samples. They run entirely in your browser, send nothing anywhere, and work with the network switched off.

Escape room

Closing Time

A two-puzzle taster of the escape-room engine: a countdown, a hint ladder that costs you time, and answers the app checks without ever storing them in readable form. A real commission runs six to eight puzzles.

Business tool

Instant quote calculator

The kind of thing that stops a small business writing the same quote email forty times a month. Pick the job, watch the price build itself, copy the finished quote to the clipboard. Every number is visible and editable in the source.

Open the calculator
Quiz

What should you build first?

A six-question branching quiz that scores your answers and recommends one of the four service lines, with the reasoning shown. The same pattern works for product finders, eligibility checks and triage forms.

How a commission runs

Four steps, no surprises

The whole process is designed so you know the price and the date before any money changes hands, and so the thing you receive has already been used, not just written.

  1. You describe the job

    A few paragraphs is plenty. What it needs to do, who uses it, what happens today instead. Awkward, rambling detail is more useful than a tidy summary.

  2. A fixed price and a date, in writing

    One number, one delivery date, and a written list of exactly what is included. If the brief grows later, the price is re-quoted before anything is built.

  3. Built, then actually used

    Every build is opened in a real browser and driven end to end — every button, every edge case, phone width and desktop, light theme and dark — before you see it.

  4. You get the file, and you own it

    Source included, no license to renew, no account to keep alive. Two weeks of fixes for anything that does not behave as specified.

The house style

Why everything is one file

It is not a gimmick. It removes almost every way a small piece of software normally dies.

01

Nothing to renew

No hosting bill, no plugin subscription, no platform that changes its pricing next year. A file on a disk keeps working.

02

Nothing to break

No frameworks, no package manager, no build step. Nothing to update, so nothing silently stops working in eighteen months.

03

Nothing leaves the device

Where a tool stores what somebody types, it stores it locally by default. No database means no breach and no privacy policy to write.

04

Nothing to sign up for

Your customer opens it and uses it. Every account wall between a person and a tool is a place where they leave instead.

Have something in mind?

Describe it in a paragraph or two and the reply will be an honest one: a fixed price and a date, a suggestion for a cheaper way to get the same result, or a straight "that is not a good fit here, try this instead."
