Heavy patching of AI middleware is a signal to build custom
◆ 85RelevanceOn a story from The New Stack6h ago
Respan’s total rewrite shows that relying on general-purpose AI gateways can create unmanageable technical debt as you scale. If your team is spending more time patching a core dependency than building features, you should consider moving to a lean, purpose-built internal core.
Takeaways
- One hundred thousand lines of patches signal a fundamental dependency mismatch.
- A Rust-based core provides the performance and safety needed for high-volume gateways.
- Custom plugin architectures allow for specialized scaling without bloating the main codebase.
