A registration site with its own CRM - built by agents
Our community needed a registration page: managing sign-ups, notifications, matching payments and sending proforma invoices. It could have been assembled from off-the-shelf services - but we wanted to show that agentic software development, in this case a landing page with a simple CRM, is entirely possible today, in February 2026. From brief to production it took roughly two person-days.

How it works
The challenge
The brief came from our community: we needed a registration page that could handle simple management of sign-ups, notifications, matching payments and sending proforma invoices. It could have been done another way - there are plenty of services that will build you a landing page, connect a payment gateway and handle the accounting too. But we wanted to show something else.
The solution
To build a landing page with a simple CRM by agentic development - and show that today, in February 2026, it's entirely doable. The whole project from brief to production took roughly two person-days, which is the time you might spend just learning one of the public website-building platforms. On top of that the agents wrote the copy for the pages straight away - the only thing I had to supply myself were the images.
What to take from it
Would I let agents build complex software for lots of users and features without oversight? Probably not. But simple websites and internal apps, sure - especially today, when there are tools that verify the quality of the security and the code itself. This registration is exactly that case: a clearly bounded brief, fast delivery and fully working operation.
