Perhaps a bit awkwardly named but nice:

> bun --smol is a new CLI flag which configures the JavaScriptCore heap size to be smaller and grow slower, at a cost to runtime performance. This is useful for running Bun in memory-constrained environments.

From the example they gave (https://i.imgur.com/IDHTaAh.png):

  Bun                343 MB
  Bun with --smol    54 MB
  Node.js            138 MB
