Frequently asked questions
Fern or LlamaIndex: which one should you choose?
Choose Fern if entry budget is the priority. Choose LlamaIndex if perceived maturity and overall rating matter more. The final test should still be based on your repository.
Do Fern and LlamaIndex cover the same need?
Not exactly. Compare the real workflow: IDE, terminal, governance, code review or app generation.
How can teams run a fair test?
Use the same ticket, same repository and same data constraints, then measure saved time, errors, diff quality and monthly cost.
