What only you can do — Chandlery Docs

The short list of steps your AI assistant cannot do for you — so none of them is a surprise.

Almost everything is your assistant's job: writing the code, creating the database and storage on Cloudflare, deploying, pushing secrets, attaching your domain. You never have to find your way around the Cloudflare dashboard.

This page is the short list of things it genuinely cannot do, and when each one turns up.

You do this	When	What it involves
Create a Cloudflare account	Stage 0	Free, no card
Sign in to Cloudflare from your terminal	Stage 4, once per computer	A browser tab, one Allow button
Confirm each production deploy	Stage 5, every time	Typing a confirmation when asked
Buy a domain	Stage 5, only if you want your own	Roughly $10–15 a year
Put a card on Cloudflare	Only if you add file uploads	The first 10 GB are still free
Upgrade Cloudflare to $5 a month	Only if you send email to customers	One click; everything else here stays on the free plan
Paste keys from another service	Only if you add payments or email	Copying a key from, say, your Stripe dashboard

The one that catches people out

At stage 4 your assistant will stop and ask you to run:

pnpm exec wrangler login

A browser tab opens, Cloudflare asks whether to authorise Wrangler, you click Allow, and that is the whole thing. Once per computer.

This is not an error

If your assistant says it cannot sign in for you, nothing has gone wrong — it is simply your turn. Run the command, then tell it you are signed in and it will carry on from where it stopped.

What it costs

Nothing, to start. Cloudflare's free tier runs a real site with real users and does not ask for a card.

Three things cost money later, and only if you want them:

A domain of your own — roughly $10–15 a year. Until then your site lives at a free .workers.dev address that works perfectly well for showing people.
File uploads — Cloudflare's file storage needs a card on file, even though the first 10 GB are free. If your product does not let people upload files, you never touch this.
Sending email to your customers — Cloudflare only delivers to addresses outside your own account on its paid plan, which is $5 a month. Sending to an address you have verified on your own account is free, which is enough to test with. If you would rather not upgrade, the email feature falls back to Resend, which has a free tier of its own.

Everything else this project ships with is on the free plan, including the live rooms and the browser game.

When free stops being free

The number people quote is 100,000 requests a day, and it is the right number, but it is rarely the one you hit first. The database is:

100,000 rows written a day — a row per sign-up, per order, per comment.
5 million rows read a day — every page that loads a list reads rows.

Since 1 September 2026 Cloudflare enforces these: past the limit, database queries return an error until midnight UTC rather than quietly costing you money. That is the good version of a limit — nothing arrives on a card — but it does mean a genuinely busy product needs the $5 plan. If you get there, you have the kind of problem worth having.

If your assistant just prints an error

A good assistant tells you when it has hit one of these, what you will see, and how to say you are done. If yours only prints an error code and stops, paste the error back and ask:

Is this something I need to do myself? Walk me through it — tell me exactly what to run, what I will see, and how to tell you when it is done.
