Tools such as Helicone, Portkey and Langfuse typically work in your request path or SDK. We read billing metadata and never touch traffic. Many teams use both.

Different tools have different focus, and features change. Check each vendor for the latest.
Current prices are on their own pages: Helicone pricing, Portkey pricing and Langfuse pricing.
They see every request as it happens. That makes them great for debugging, tracing a slow prompt, setting rate limits and comparing models request by request. Setup is usually quick, and many have a free tier.
We start from the bill, not the request. Each finding has a safety label, two savings numbers with their basis, and a fix you apply yourself. We also check a later bill, on platforms that show billed cost. We cover platforms that sit outside any LLM gateway too.
You need per-request traces, live routing or rate limits, or you are debugging prompt quality.
Your bill is the worry, you want to know what is safe to change, and you would rather not add anything to your request path.
You want request-level detail day to day, and a monthly answer on what to change and whether it saved money.
How to try both: Keep your gateway as it is, connect CostAssured, and compare your first report with what your gateway shows. Nothing in your traffic changes.
No. We never sit in your request path. We read reports after the fact.
No. Many teams use both. They answer different questions.
They change often. We link to each vendor's own pricing page instead, so you always see the current price.
