About Langfuse
Langfuse helps teams ship AI products with better visibility into prompts, traces, costs, latency, and quality over time. It is built for LLM engineering workflows where observability and evaluation are part of the core development loop.
Because it supports open-source and self-hosted deployment patterns, it is especially relevant to teams that want more control over their AI stack while still getting product-grade monitoring and feedback loops.

Evals
Clarify during review
Open source + cloud plus agent-runtime, model, or workflow consumption should be clarified during procurement.
Human oversight
Approval gates
- Clarify which actions pause for human review versus execute automatically.
- Document whether admins can require approval before outbound messages, record updates, purchases, or payments.
- Confirm that approval events are visible in audit logs and trace history.
Systems
Connected systems and execution surfaces
Connected systems
- CRM, support, docs, browser, messaging, and custom APIs should be documented before rollout.
- Check whether admins can scope tool access by workflow, user role, or environment.
- Ask which systems are first-class integrations versus custom connectors.
- Typeform
- AWS
- OpenAI
- Anthropic

Models
Model stack, observability, and evals
Model stack
- Supported model providers and routing controls should be explicit.
- Clarify fallback behavior between providers, models, or prompts.
- Check whether model choice is buyer-configurable by workflow.
Observability
- Trace visibility across prompts, tool calls, latency, and cost.
- Audit trail for approvals, failures, retries, and handoffs.
- Operational analytics that help teams understand run quality over time.
Eval coverage
- Regression datasets for critical workflows and prompts.
- Task-success or rubric-based scoring on agent outcomes.
- Human-review loops to validate edge cases before broad rollout.
Governance
Data boundaries and fallbacks
- Retention windows, model-training policy, and tenant isolation should be explicit.
- Per-tool permissions and least-privilege access matter for production rollout.
- Confirm PII handling, redaction controls, and region or residency options.
Langfuse should document how runs pause, retry, escalate, or hand off when confidence drops or a tool step fails.
