Where each one falls short

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

Amazon Q Developer

Deepest value and AWS-specific expertise is tied to the AWS ecosystem, less compelling for non-AWS shops
Free tier caps agentic requests at 50 per month, which can be exhausted quickly on larger tasks
Additional transformation usage beyond plan limits is billed per line of code, adding unpredictable costs
GitHub and Eclipse integrations are still in preview, indicating incomplete platform coverage

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
