Cadenya selects agent variations with the best feedback using Thompson Sampling and can run in the frontend, giving widgets their own hostname with CORS settings plus a widgets-sdk and React components. The founder is offering a promocode for a free account with $20 of credit to users who email support@cadenya.com with the subject \"Saw on HN\".", "body_md": "My name is Robert, and I'm the founder of Cadenya, an agent runtime.\n\nCadenya is not like other managed solutions. Instead, it uses your API or MCP servers as the tools in your agentic loop, which also is managed.\n\nCadenya is also agnostic to the model provider. Wire up OpenRouter, or any OpenAI compatible endpoint, and it will use it for inference.\n\nIt also supports agent variations - where Cadenya will select the agent's with the best feedback using Thompson Sampling.\n\nAnd finally, Cadenya can be used in the frontend. Widgets receive their own hostname with CORS settings, and you can leverage the widgets-sdk and react components to build an agentic experience in the browser, without any complex backend logic.\n\nEmail support@cadenya.com with the Subject \"Saw on HN\" and get a promocode that unlocks a free account with $20 of credit.\n\nComments URL: [https://news.ycombinator.com/item?id=49651207](https://news.ycombinator.com/item?id=49651207)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-cadenya-an-agent-runtime", "canonical_source": "https://www.cadenya.com/", "published_at": "2026-09-10 22:52:18+00:00", "updated_at": "2026-09-10 23:18:42.482443+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "ai-products", "developer-tools"], "entities": ["Cadenya", "Robert", "OpenRouter", "MCP", "Thompson Sampling", "widgets-sdk"], "alternates": {"html": "https://wpnews.pro/news/show-hn-cadenya-an-agent-runtime", "markdown": "https://wpnews.pro/news/show-hn-cadenya-an-agent-runtime.md", "text": "https://wpnews.pro/news/show-hn-cadenya-an-agent-runtime.txt", "jsonld": "https://wpnews.pro/news/show-hn-cadenya-an-agent-runtime.jsonld"}}
