Helicone vs WSO2 AI Gateway

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.

WSO2 AI Gateway governs AI APIs and generative AI services with usage visibility, guardrails, prompt management, and semantic caching. Its out-of-the-box language-model support includes OpenAI, Mistral AI, and Azure OpenAI. Built-in controls check prompts semantically, mask PII, validate JSON Schema and regex rules, limit output length, and check URLs; Azure Content Safety and AWS Bedrock Guardrails are listed as external integrations. The gateway monitors backend limits by request and token count and manages subscription access. Prompt templates can standardize inputs and add role or context instructions. Model-level analytics and semantic caching are intended to help reduce repeated calls and improve response speed and cost efficiency. WSO2 also describes converting REST APIs into MCP-compatible tools and governing access to MCP servers. Moesif-powered analytics tracks AI and agent traffic. Deployment can be on-premises or in the cloud. The SaaS-only 30-day trial costs nothing and includes 1M AI Gateway events, five managed LLM APIs, and one hybrid gateway. Growth costs $119 a month; Enterprise pricing is custom.
