wormhole

Adoption verdict: wormhole is worth a look if you are building Go backends that need to talk to multiple LLM providers, but the current evidence is extremely limited and mostly comes from the project's own GitHub repository. That makes it better as an early project to evaluate yourself than as a proven default choice.

In practical terms, this is not a chatbot app and not a workflow orchestration platform. A better comparison is a Go multi-provider LLM abstraction layer or gateway SDK. Its stated role is to unify access to OpenAI, Anthropic, Gemini, Ollama, and OpenRouter, while emphasizing adaptive rate limiting and concurrency control. For teams building internal AI services, proxy layers, or batch systems, the concrete output is usually cleaner provider integrations, easier switching, and more controlled request handling.

On cost and adoption friction, the evidence only supports that it is open source and supports multiple providers. There is no pricing page, hosted-service pricing, or API markup evidence here, so we should not infer direct product pricing.
