adopting Start means joining an ecosystem of modular, composable tools rather than committing to a monolithic framework. Each piece works independently or together.

A core conviction at Sakana AI is that the most capable AI systems will not be monolithic models scaled in isolation, but collections of specialized agents working together.

when projects want to keep strict boundaries within their code and avoid becoming an entangled monolith. This is for example the case for Yarn itself, or many enterprise codebases.

I'm building a Rails API with a separate web frontend app as "just another API client" (various smartphone apps to follow as well). In the previous "monolithic" version of the service, where all the server side was rolled into one Rails app

But I believe the core philosophy of tiny modules is actually sound and easier to maintain than giant frameworks.

and how moving to a monolith was the solution that worked for Segment.

Clients are updated to use the new service rather than the monolith endpoint. In the interim, steps such as database replication enable microservices to host their own storage even when transactions are still handled by the monolith. Eventually, all clients are migrated onto the new services. The monolith is "starved" (its services no longer called) until all functionality has been replaced. The combination of serverless and proxies can facilitate much of this migration.

A monolithic server-run web app that relies on Ruby, Node, or another backend language.

There is some confusion around what makes a headless CMS truly “headless”, as vendors use the term somewhat loosely to label their decoupled or hybrid CMS systems. But a true headless CMS is one that was built from the ground up to be API-first, not a full monolith CMS with APIs attached afterwards.
