Helicone
Open-source LLM observability platform and AI gateway with request logging, caching and routing; US or EU cloud regions.
Observability is the starting point, with the gateway added on, so it suits teams that mainly want to log and inspect LLM traffic. Hosted plans run from the free Hobby tier, with 10,000 requests and 1 GB of storage a month, to Pro at $79 and Team at $799, each plus usage-based charges for requests and storage. Gateway credits carry no markup, unlike OpenRouter or Requesty. An EU region is selectable and the code can be self-hosted, though no DPA is listed.
