Helicone logs and routes. CostSlice is OpenAI cost per customer.
Helicone is the right tool if you want a gateway. CostSlice is the right tool if the product is already on OpenAI and you need cost per customer so you can change a price.
Helicone is an AI gateway. It logs. It can cache. It can route across providers. That is a real product.
CostSlice is OpenAI-only. Pass-through. Completions still go to OpenAI with your OpenAI API key. We do not store prompt or completion bodies. We tag tenant and feature and show a customer P&L.
| Helicone | CostSlice | |
|---|---|---|
| Kind | Gateway | Pass-through + customer P&L |
| Prompt bodies | Can log | Never stored |
| Providers | Many | OpenAI only |
Privacy angle: without storing prompts.
