I replaced a $120/year micro-SaaS in 20 minutes with LLM-generated code

I have been sceptical of the manifold claims that software-as-a-service (SaaS) will be killed by LLMs. The theory behind this idea is:SaaS is a pure software product. People who pay SaaS vendors do so because it’s cheaper to buy this software than build it.LLMs dramatically reduce the time and cost of building custom software.Therefore, most SaaS vendors will go out of business because most companies/teams will prompt an LLM to write the software they need, such as for ticketing, meetings, customer relationship management, etc.The reason for my scepticism has been that SaaS such as HR software Workday is more than just software. Workday, for example, keeps up with compliance requirements (e.g., for holiday pay in different countries), guarantees correctness (e.g., payslips that comply with local regulations), and over time the software keeps up to date with changes in the external and internal environments.However, this week I had first-hand experience of how ridiculously easy it is now to replace SaaS with LLMs. On my website – pragmaticengineer.com – I have a testimonials section, which displays real LinkedIn and X posts about this publication. It cost $120/year for a small service called Shoutout.io, and looked like this:Testimonials, nicely collected and rendered by ShoutoutAnd this is the backend: nothing fancy, just a way to add, edit, reorganize, and delete testimonials.Shoutout’s admin interfaceI was a customer for four years and logged in perhaps once a year...
