LLM Gateway vs WSO2 AI Gateway

LLM Gateway provides one OpenAI-compatible API for routing requests among more than 250 models from over 40 providers. If a provider errors, times out, or rate-limits a request, it can retry up to twice with another provider for the same model. Its dashboard tracks request, token, spend, latency, error, and cache metrics, with model and provider breakdowns. Teams can use their own provider API keys without a platform fee and pay providers directly. The open-source core is licensed under AGPLv3 and can be self-hosted for free; enterprise features require a license. The Free plan is free, billed free forever, and has a 5% fee on credit usage. It includes 200+ models across 40+ providers, activity logs and export, and 20 requests per minute on free models; paid models are not rate limited. Enterprise pricing is custom and not listed. It includes custom routing, unlimited data retention, a 99.9% uptime SLA, and 24/7 priority support. Published integration guides cover tools including Claude Code, Cursor, Codex CLI, Cline, n8n, and VS Code.

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.
