Helicone vs KeepRouter

Helicone routes, debugs, and analyzes AI applications through a gateway and observability tools. The gateway provides access to more than 100 models through the OpenAI SDK by changing the model name, and supports load balancing, automatic failovers, and response caching across providers. Helicone logs requests in real time and visualizes multi-step LLM interactions to help locate error causes. Listed integrations include OpenAI, Anthropic, Azure, LiteLLM, Anyscale, Together AI, and OpenRouter. It can run in customer infrastructure through single-click deployment or a production-ready Helm chart; Helicone also states that its cloud is SOC 2, HIPAA, and GDPR compliant. A LangGraph integration tracks calls, sessions, performance, and costs, while an API cost calculator covers more than 300 models and providers. The free Hobby plan includes 10,000 requests, 1 GB storage, one seat, one organization, and seven days of retention. Pro costs $79.00 per month. A seven-day trial is advertised. Helicone says its services remain live in maintenance mode following acquisition by Mintlify, with security updates, new models, and bug and performance fixes continuing.

KeepRouter is a cloud API gateway that puts models from multiple providers behind one account. Its compatible chat models accept OpenAI Chat Completions requests at /v1/chat/completions and Anthropic Messages requests at /v1/messages, including use with Claude Code and the Anthropic SDK. The production catalog lists 101 models with public customer prices and supported endpoints. It covers text, image, video and speech output, with billing units varying by modality. The model named free charges $0.0000 per 1M input tokens and $0.0000 per 1M output tokens, supporting chat completions, streaming and tool calling where available. Paid usage uses prepaid USD credit rather than a recurring subscription. Keys can be restricted to model allowlists, while the raw key appears once at creation. Logs capture request operations without prompt or completion bodies. KeepRouter runs on Cloudflare’s global edge network, supports OpenCode and Continue setup, and says customer data is not used for model training.
