| Documentation | Documentation covers observability, prompt management, evaluation, metrics, APIs, SDKs, integrations, compatibility, deployment, and security with versioned self-hosting guides. | Treblle can generate API documentation from live traffic and synchronize it with deployments while detecting specification drift. |
| Integrations | Langfuse lists more than 100 integrations spanning OpenTelemetry, Python and TypeScript, model providers, agent frameworks, gateways, and developer tools. | The documentation lists gateway integrations for AWS API Gateway, Azure API Gateway, Kong, MuleSoft, Traefik, WSO2, and Apigee, plus language and framework integrations including Express, Spring Boot, Django, .NET, Go, and Ruby on Rails. |
| Observability | Hierarchical traces capture LLM calls, tool invocations, and retrieval steps, with filtering by user, session, cost, latency, and metadata. | Its API observability provides real-time visibility into more than 50 data points per request, including performance, errors, consumer behavior, and payload content. |
| Product | Langfuse is an open-source AI engineering platform that helps teams collaboratively debug, analyze, and iterate on AI agent applications. | Treblle describes itself as an enterprise runtime intelligence platform for discovering and securing APIs and agents across clouds, gateways, and technologies. |
| Security | Langfuse reports annual SOC 2 Type II and ISO 27001 audits, external penetration tests, encryption, access controls, GDPR compliance, and a HIPAA-ready region. | Treblle says it detects more than 20 threat types in real time across API traffic, including OWASP Top 10, SQL injection, broken authentication, shadow endpoints, and payload anomalies. |
| Support | Hobby includes community support via GitHub, Core includes in-app support, Pro includes prioritized in-app support, and Enterprise includes support SLA and a named lead support engineer. | The pricing comparison lists community support, live chat support, a dedicated customer success engineer, custom-built SDKs, and security questionnaire help as support features. |

In their own words
Langfuse
Langfuse is an open-source AI engineering platform for teams debugging, analyzing, and iterating on AI agent applications. Its tracing records prompts, model responses, token use, latency, tool calls, retrieval steps, and metadata. Prompt Management stores, versions, deploys, and tests prompts, then links them to traces. Evaluation features include LLM-as-a-judge, code evaluators, user feedback, manual labeling, datasets, and experiments. Integrations include Python and JS/TS SDKs, OpenTelemetry, an API, CLI, MCP Server, and popular AI frameworks. Teams can self-host the MIT-licensed core on customer infrastructure using Docker, with options including Docker Compose, Kubernetes, AWS, and Azure. Langfuse reports annual SOC 2 Type 2 and ISO 27001 audits, external penetration tests, GDPR compliance, a DPA, and a HIPAA-ready region. Its Cloud traffic uses TLS 1.2+ and stored data uses AES-256 encryption. The free Hobby plan is free and includes 50k units per month, 30 days of data access, two users, and community support via GitHub. Core costs $29 a month, billed monthly.
Treblle
Treblle is an enterprise platform for finding and securing APIs and agents across clouds, gateways, and technologies. Its observability tools show more than 50 data points per request in real time, covering performance, errors, consumer behavior, and payload content. It detects more than 20 threat types, including SQL injection, broken authentication, shadow endpoints, and payload anomalies. Discovery searches code repositories, gateways, and live traffic; governance adds maturity scoring, design-time rules, CI/CD integration, and drift detection. Treblle can generate documentation from live traffic and keep it synchronized with deployments. Listed integrations include AWS API Gateway, Kong, Apigee, Express, Spring Boot, Django,.NET, Go, and Ruby on Rails. Deployment choices are SaaS, on-premises, air-gapped, and private cloud, with stated feature parity. On-premises data stays within the customer's network; private cloud runs in the customer's AWS, Azure, or GCP account and selected region. Core costs $233 a month, billed yearly, and includes five APIs, five million monthly requests, and 30 days of retention. Aspen is a native API client for Windows and Mac.
