S.01 What we build on
A small set of well-understood tools.
Grouped by what each one does once your product is live.
01
Where your product lives
These accounts are in your name from day one.
Supabase
The database and the logins behind every product. Customer records, accounts and sign-ins live here, in a project opened in your name.
PostgreSQL
The database itself. It decides who may see which records.
Vercel
Hosting, a link to see changes before they go live, and work that runs on a timer.
Cloudflare
Domains, page speed and live video.
GitHub
Where the code is kept, and where it gets checked.
02
What it is written in
You can hire for any of these in Toronto.
Next.js
What our websites and web apps are built with.
TypeScript
The language it is written in. Every file is checked before release.

03
What it connects to

S.02 Running
See them working.
Open one and it runs.
01 Who is allowed to see which records
Postgres select * from bookings
create policy bookings_own on bookings for select using (user_id = auth.uid() or public.is_admin());
0 rows. The policy denied every row to this caller.
6 of 6 rows returned · every row is in the table; the policy decides which of them a user gets
The rule runs inside the database, not in the app.
02 A payment, including the one that fails
Stripe PaymentIntent

Boring on purpose.
What a tool has to pass before we build with it.
Portable
It runs anywhere
Postgres works the same wherever it runs, so you can move it.
Proven here first
We run it ourselves
Every tool on this list runs our own products too.
Hireable
Someone else can take it over
Every language on this list is one you can hire for in Toronto.
What we have built with it is in the technology portfolio. Our own apps, Mr. Indecisive, The Dispatch and Find The Title, are on the App Store.
