Flowlines

Flowlines provides behavioral observability for production AI agents by instrumenting every call and constructing a structured execution graph that captures prompts, tool usage, memory reads, and decisions across sessions and users. The platform continuously monitors agent behavior, identifies recurring failure patterns, and surfaces the precise memory modification needed to prevent the next occurrence, presenting evidence‑backed, reversible fixes. It integrates with any LLM provider and offers a two‑line SDK for Node and Python, enabling session replay with branching, cost attribution, and automated Slack alerts grouped by cohort. Designed for developers who need to track and correct agent behavior at scale, Flowlines abstracts token‑level logs into searchable traces, supporting twelve predefined failure modes out of the box while allowing custom, typed, versioned fields to be reviewed before they are applied.
