Bun appears to be specializing in startup velocity, which makes it a sensible choice for edge use instances, stated Andrew Cornwall, senior analyst at Forrester Analysis. However which means it’s competing with WebAssembly runtimes that may begin even sooner, he stated.
Nonetheless, Bun is already displaying attention-grabbing sufficient efficiency to make builders think about it as a substitute for runtimes akin to Node.js and Deno, stated Holger Mueller, vice chairman and analyst at Constellation Analysis.
However whereas Zig can compile to Home windows and Arm, it’s a less-well-known language, which limits Bun’s potential developer pool, Cornwall stated.

Bun might have adoptability points
Whereas Deno and Node.js can run on a number of platforms, Bun is tied to high-performance Unix variants — macOS (x86 and Arm), Linux or Microsoft Home windows Subsystem for Linux (WSL), which limits its use, Cornwall stated. Home windows builders should use WSL — which is primarily aimed toward Linux builders working in a Home windows surroundings and comes with limitations akin to solely being accessible for Home windows 10.
Regardless of these drawbacks, Bun is value watching — particularly if it picks up sponsorship from a significant edge supplier who needs to exchange V8 for short-running duties, Cornwall stated.
“It is unlikely that Bun will trigger a large-scale flight from Node.js simply but, nevertheless it may discover a place within the toolbox,” Cornwall stated.
Builders can set up Bun by operating an install script to obtain Bun from GitHub.
