Langfuse Was Absorbed
by ClickHouse. Get Observability
That Comes With Governance.
ClickHouse acquired Langfuse in January 2026 as part of their $400M Series D at a $15B valuation. Langfuse’s product direction is now tied to database infrastructure -- not AI governance. Curate-Me is the independent alternative with a full governance chain, managed runners, and observability built in.
Keep your Langfuse tracing. Add governance in 5 minutes with one base URL. Zero code changes.
What the ClickHouse acquisition means for Langfuse users
Langfuse had 2,000+ paying customers and 26M+ SDK installs per month -- used by 19 of the Fortune 50. Now its roadmap is tied to ClickHouse’s database infrastructure vision, not independent AI governance.

Everything Langfuse had, plus what it never built
Curate-Me includes observability and tracing, but goes further with a full governance chain, managed runners, and compliance tooling.
Budget Enforcement
Langfuse tracked what you spent. Curate-Me stops you from overspending. Real-time daily budgets and per-request cost limits deny requests before they reach the provider.
PII Scanning
Regex-based detection for API keys, credit card numbers, SSNs, and PII in request content. Block or redact automatically before data reaches any LLM provider.
Model Allowlists
Control which models each organization or team can use. Prevent accidental calls to expensive models. Supports wildcards (e.g., gpt-4* allows all GPT-4 variants).
HITL Approvals
Requests above a configurable cost threshold are held in an approval queue. Review, approve, or deny from the dashboard with full request context.
Managed Runners
Secure OpenClaw sandbox containers with 4-tier access control, network phase separation, and immutable audit trail. Langfuse had no execution environment.
Immutable Audit Trail
Every governance decision, every request, every cost event -- recorded in an append-only audit log. Time-travel debugging lets you replay any agent execution step-by-step.
Time-Travel Debugging
Replay and inspect any agent execution step by step. See the exact state at each checkpoint. No other gateway offers this level of debuggability.
Desktop Streaming
VNC and RDP streaming lets you watch agents interact with desktop environments in real time. Built on Guacamole for browser-based access.
EU AI Act Ready
Full audit trail, governance chain documentation, and compliance reporting designed for EU AI Act requirements. Stay ahead of regulation.
