We also need support for decorators in TypeScript. We have been similarly using Langsmith, using their traceable method that allows ingestion of different types like chain, tool, and LLM, etc, and also constructs the call tree identical to how it's shown on your website (probably using Python). We have been facing issues with Langsmith at our current production scale and are looking for alternative providers. We feel that Phoenix is the closest option.
By the way, Langsmith also offers an easy-to-use take to playground option for LLM calls, where the playground pre-fills the entire conversation with other settings, such as model and tools. Does Phoenix have a similar support?
