| Need better exports | Existing Helicone ETL first | Complete bodies and metadata in a reconciled archive |

Keep the gateway decision separate
Helicone routes requests to model providers. Replacing it can affect endpoints, credentials, streaming and retries; changing observability alone does not require that cutover.
Preserve the features you use
Helicone also offers prompts, datasets, exports and observability MCP access. Check these alongside custom tool execution, session context and error visibility.
Move one workload first
Keep the existing route while testing new instrumentation. Export a sample with the request bodies and metadata your debugging or evaluation workflow needs.
Questions & answers
Does Lunary replace every Helicone gateway feature?
Lunary is an observability and development platform, not a provider gateway. Keep or replace routing separately while you move conversation and application tracing to Lunary.
Does Helicone offer MCP access?
Yes. Its MCP server queries observability data, unlike a documentation-only server.
