+3 more

Pros

1M+ users validates real-world adoption and ensures long-term support and development
Composer multi-file editing reduces refactoring time significantly versus single-file suggestions
JetBrains support means teams using IntelliJ or PyCharm no longer need to switch editors
Codebase indexing makes AI suggestions context-aware across 100K+ line repos, not just the open file

Cons

Credit system is opaque — using premium models (o3, Claude Opus) burns credits fast; $100+/mo for heavy users
Pro plan ($20/mo) includes 500 fast premium requests; exceeding this drops to slow queue or extra charges
Marketplace extensions are community-maintained with variable quality and no official vetting
JetBrains support is newer and has fewer features than the VS Code-based native editor
Requires internet for AI features — not suitable for air-gapped development environments
