Viktor opens Langfuse, runs the work, and posts back what changed. Sensitive actions wait for your approval. Everything is logged. You stop doing the work and start reviewing it.
A Langfuse AI agent is an AI that connects to your Langfuse account and completes work in it - it doesn't just answer questions about Langfuse, it takes the actions. Viktor is that agent: an AI employee that works in Langfuse on your behalf and delivers the finished result in Slack or Microsoft Teams.
Unlike workflow builders such as Zapier or Make, there is nothing to configure - no triggers to map, no workflows to maintain. You describe the outcome in plain English, and Viktor picks the right Langfuse actions, chains them with the other 3,200+ tools it connects to, and asks for approval before anything sensitive runs.
Open source LLM engineering platform. Traces, evals, prompt management and metrics to debug and improve your LLM application.

Review-first approvals: sensitive Langfuse actions wait for your sign-off before they run.
