Choose Portkey AI Gateway if...
- LLM routing
- provider fallbacks
- cost control
- production gateway

custom LLM proxy
Custom or external option
Choose custom LLM proxy if...
- Choose this path if you need a narrow internal solution, a lower-level primitive, or a tool outside this directory.
Not ideal if...
- Not ideal if you still need a maintained product profile, docs trail, and comparable evaluation criteria.
What to consider
- Does the alternative solve the same agent layer, or is it a lower-level building block?
- Will switching improve observability, permission boundaries, state control, or evaluation coverage?
- Can the team validate the migration with one real agent task before replacing the current tool?
