Langfuse alternative
Langfuse is an open-source OTel-native LLM observability platform (Apache-2.0 licensed) with strong community adoption and prompt management features. Perimattic AI Suite adds regulatory compliance built-in (HIPAA, EU AI Act, DORA, BaFin, MAS FEAT, DPDP), dedicated enterprise support, and managed deployment for teams that need observability plus compliance in one platform.
Langfuse at a glance
Instrument once, observe everything
One OTel SDK, one OTLP exporter. No proprietary agents or middleware sitting in the critical request path.
Eval scores on production traffic
Faithfulness, answer relevancy, and hallucination rates measured on live requests — not just curated test sets.
Compliance evidence built in
Structured audit logs formatted for HIPAA, EU AI Act, DORA, and MAS FEAT. No manual export, no post-processing.
What Langfuse is and where it excels
Langfuse is an open-source LLM observability platform founded in 2022. It uses OTel-native span tracing, provides a hosted cloud and self-hosted options (Apache-2.0 license), and has strong community adoption particularly in Europe. Core capabilities include: distributed traces, prompt management, dataset management, eval scoring, and cost tracking. The open-source model means the community contributes integrations rapidly — LangChain, LlamaIndex, OpenAI SDK, Anthropic SDK, and dozens more.
The right fit for Langfuse
Where Langfuse excels: small-to-medium teams that need cost-effective observability with good framework coverage, teams that want to self-host under Apache-2.0 with full control of the codebase, and teams that need prompt management (versioning, A/B testing prompts) as a core feature alongside tracing.
The compliance gap Langfuse does not fill
Langfuse's gap is regulatory compliance. It does not ship built-in PHI redaction, HIPAA audit trail configuration, DORA incident classification, or EU AI Act post-market monitoring templates. Teams in regulated industries (healthcare, financial services, government AI) must build these compliance layers themselves on top of Langfuse — or choose a platform that ships them out of the box.

Prompt management Built-in (versioning, A/B test) | Prompt management No (focus is compliance observability) |
Enterprise support Community + paid cloud plan | Enterprise support Dedicated SLA-backed support |
Cost attribution Per-model cost tracking | Cost attribution Per-model + per-agent + per-user |
Common questions, answered
Answers to the most common questions about this regulation, what it requires, and how AI observability helps you meet it.
What is Langfuse?
Langfuse is an open-source LLM observability and prompt management platform. It provides OTel-native distributed traces, eval scoring, dataset management, and a prompt playground. It is licensed under Apache-2.0, meaning you can self-host the full platform at no licensing cost. Langfuse raised funding and launched a hosted cloud service in 2023–2024.
What does Perimattic AI Suite offer that Langfuse does not?
The primary difference is regulatory compliance infrastructure: PHI redaction for HIPAA, audit trail configuration for EU AI Act, DORA incident classification, BaFin model-risk monitoring templates, MAS FEAT accountability trails, and OSFI E-23 evidence exports. Langfuse is an excellent observability tool for teams without regulatory requirements; Perimattic AI Suite is built for teams that must simultaneously satisfy compliance obligations.
Is Langfuse MIT or Apache licensed?
Langfuse is licensed under Apache-2.0, not MIT. Both are permissive open-source licenses that allow commercial use and modification. Apache-2.0 adds an explicit patent grant clause that MIT lacks — relevant for enterprise legal review. The core platform is Apache-2.0; some Langfuse enterprise features (SSO, RBAC, audit logs) require a paid commercial license.
Can I migrate from Langfuse to Perimattic AI Suite?
Yes. Both platforms use OTel-native span tracing with gen_ai.* semantic conventions. If you are already emitting OTel spans to Langfuse, you can point the OTLP exporter at Perimattic AI Suite without changing your instrumentation code. Historical traces can be migrated; existing integrations (LangChain callbacks, OpenAI SDK wrappers) continue to work.
