Migration Effort
Switching tools always has a cost. Consider data export capabilities, API compatibility, and how much of your workflow depends on LangChain-specific features.
Team Size
LangChain is solo-friendly, so look for alternatives that also work well for one-person operations without requiring enterprise setup.
