The short version

Each has a real cost: Bun linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported; Pinecone reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Bun

Linux requires kernel 5.6 or higher (5.1 minimum but with compatibility issues); older systems not supported
Native Node.js addons not supported directly; requires FFI workarounds for C libraries
Ecosystem less mature than Node.js; fewer third-party packages optimised for Bun
Windows support newer and less mature than Linux/macOS; occasional edge cases

Pinecone

Reads and writes are billed on separate meters, and reads are far more expensive, at $16 to $18 per million against $4 to $4.50 for writes on Standard
Unit prices vary by region, so the same workload costs different amounts in different places
The Standard plan carries a $50 monthly minimum and Enterprise $500, charged whether or not the usage reaches it
Enterprise pays more per unit as well as more in minimum, at $24 to $27 per million reads against Standard's $16 to $18
Indexes and namespaces are capped by plan, at 5 indexes on the free tier and 20 on Standard
RBAC and SSO require the Standard plan
