As answered by people managing Braintrust.dev and usePropane.ai.
usePropane.ai's answer:
We spent years in product leadership watching the same problem repeat itself. Customer data everywhere, context nowhere. Teams rebuilding the same understanding every sprint, agents building without knowing what customers actually need. Propane is the infrastructure we wished existed. The context layer that connects your stack, keeps itself up to date, and gives your team and your agents one shared picture to build from.
usePropane.ai's answer:
Our customers are product teams at fast-moving B2B SaaS companies who are already building with a range of coding agents. They are scaling fast and do not want to build their own context infrastructure. They need their agents to work from real customer signals, not assumptions, and they need their whole team aligned on the same picture.
usePropane.ai's answer:
Most tools ask you to bring the context. Propane builds it for you. It connects your entire stack into one shared layer that updates automatically, so your team and your agents always build from the same picture of what customers need. No manual upkeep, no context gaps.
usePropane.ai's answer:
Because the problem is not insight, it is shared context. Other tools help you collect or analyse. Propane gives your whole team and your agents one live layer to build from. That is what makes product teams faster and agents more accurate.

usePropane.ai's answer:
We build on a modern, multi-modal AI stack using best-in-class models and infrastructure. Deep native integrations and MCP connectors keep your data flowing in real time. Currently web-based, with enterprise-grade security built in from day one.

Braintrust focuses on evaluation-driven development: the idea that monitoring LLM applications means continuously scoring outputs against quality criteria, not just tracking latency and error rates. It's an eval platform first, with... - Source: dev.to / 3 months ago
You're monitoring production traffic. You need Langfuse / Phoenix / Helicone / Braintrust for that. Online eval is a different problem class: implicit feedback, drift detection, hallucination rates on your data, not on HellaSwag. - Source: dev.to / 3 months ago
Same approach works with Langfuse, Phoenix, Braintrust, or your existing OTel pipeline — the metadata.userId pattern is the universal part. - Source: dev.to / 4 months ago
