You also get 12 months of all 400+ guides and 100+ recipes, and all eight books. Nothing renews on its own.

Buy the Toolkit or the Team Toolkit, and for 30 days from that first purchase you can ask for a full refund, for any reason. Email support@developertoolkit.ai and it is refunded. The guarantee covers one first purchase per customer and does not cover renewals. Your statutory rights as a consumer apply as well, as set out in the Terms.
Polar, the merchant of record, takes the payment and emails an invoice with the VAT or sales tax for your country right after you pay. Prices in USD. The total for your country, with any VAT or sales tax, is shown at checkout before you pay. The Polish pages list prices in złoty.
Something else? Write to support@developertoolkit.ai and the author answers.
No. You pay $59.99 once and get 12 months of access. Nothing renews on its own: when the 12 months end, you decide whether to renew, and you are charged only if you do.
Your access ends unless you renew. You keep the free 10 articles a month, and new book editions and new Setup Packs wait for a renewal. The books and Setup Pack files you already downloaded are yours to keep.
A renewal is $29.99 for another 12 months, less than half the first-year price. Anyone who has bought the Toolkit can renew, before or after their access ends. The months are added to your end date, or counted from today if your access has already ended, so renewing early costs you no days. A Team Toolkit renewal is $149.99.
Yes. You have 30 days from your first purchase of the Toolkit or the Team Toolkit to ask for a full refund, for any reason. Email support@developertoolkit.ai and it is refunded. The guarantee covers one first purchase per customer, so renewals are not covered. Your statutory rights as a consumer apply as well, as set out in the Terms.
Nothing. Your subscription keeps renewing at the price you have now until you cancel, and you manage it from your account page as before. If you cancel later, you can buy the Toolkit like anyone else.
A Toolkit is for one person, and the books carry your name and email. For colleagues there is the Team Toolkit: their own access for up to 10 people on one invoice, cheaper than separate Toolkits from the sixth person.
After you buy, you have the full Toolkit yourself, and you can add up to 9 email addresses on your account page. Each person signs in with that address and gets everything in the Toolkit until the team’s end date. You can remove someone and add someone else at any time.
Yes. Polar, the merchant of record, issues an invoice with the VAT or sales tax for your country and emails it right after payment. The Team Toolkit comes on one company invoice for everyone. Services for teams are invoiced by Wondel.ai after a written proposal.
Prices in USD. The total for your country, with any VAT or sales tax, is shown at checkout before you pay. The Polish pages list prices in złoty.
Yes. A pack you bought stays yours, and you can regenerate it whenever your stack changes, as before. The Toolkit adds the guides and the books.
Start with the part that does the work for you. Generate the Setup Pack, which takes about 20 minutes, then write intent.md, spec.md and plan.md for something you were going to build anyway and run it in your tool. That is one change done the new way in your first week. If it still is not for you, the 30-day refund covers a first purchase.

You can ask, and the answer will sound right. Ask about Codex approval settings and you may get --approval-mode, which does not exist. The real flag is --ask-for-approval (-a), with the values on-request and never (Codex CLI 0.159.2, checked 2026-10-02). Every guide shows when it was last updated, and the flag catalogue names the release each entry was checked on.
