As answered by people managing MailClark and StackDiet.app.
StackDiet.app's answer:
StackDiet focuses on building the smallest practical AI and SaaS stack for a user's actual jobs, instead of simply listing popular tools. It looks for unnecessary overlap, considers whether each tool has a distinct role, and can start from either predefined jobs or a plain-English description.
StackDiet.app's answer:
StackDiet is designed for decision-making rather than endless browsing. It helps users identify what they actually need, reduce overlapping subscriptions, and compare tools by the jobs they perform. It is free to use, requires no signup, and does not hide recommendations behind a paid report.
StackDiet.app's answer:
Freelancers, creators, small businesses, marketers, webshop owners, and other people who use multiple AI or SaaS tools and want a simpler, more cost-conscious stack with less unnecessary overlap.
StackDiet.app's answer:
StackDiet was created to solve a common problem: people keep adding AI and SaaS subscriptions without a clear view of which jobs each tool is actually doing. The project started from the idea that a software stack should be treated like a system of jobs to cover, not a collection of product logos. The goal is to help users build a leaner stack with fewer redundant tools.
StackDiet.app's answer:
HTML, CSS and JavaScript for the web application, with Cloudflare Pages and Cloudflare Workers for hosting and backend services. Cloudflare D1 is used for the feedback system.
