Ship AI agents without the operational burden
Build, run, and control agents without managing the infrastructure around them.
Build and launch agents quickly, connect them to your existing tools, and control how they act with policies, human review, and full run history.
Example run tree: session steps from perceive through handoff, with timings and decision outcome.
Build agents with tools, context, and control
Give agents the access they need—without a blank check on your systems and data.
Wire APIs, tools, and data through managed integrations, then set what each agent may do, what needs approval, and what never runs.
Multi-Agent Systems
Compose agents that call sub-agents, governed by cycle detection, depth limits, and session-wide token and time budgets across the whole tree.
Human-in-the-loop
Pause for approval, choice, or input on sensitive steps and resume exactly where the agent left off — no replay, no lost context.
Agent-in-the-loop
Sub-agents ask their parent for clarification mid-run. The parent answers from its own context or quietly escalates to a human.
Embedded AgentsNew
Run agents inside your product through a stable API without exposing user credentials or stitching together your own session and tool plumbing.
Observability & Traceability
Every reasoning step, tool call, and decision is captured as a structured, replayable event — queryable timelines, not log files.
Firewall
Inline checks block risky tool calls in microseconds; async detection learns each agent's baseline and catches anomalies before the next run.
Deploy agents without managing agent infrastructure
Agentic work needs more than prompts: sessions, tools, approvals, state, and audit. Phrony provides that runtime layer out of the box.
Deploy into a shared, governed environment—without custom orchestration, logging, and review wiring for every agent. Every run is isolated, observable, and traceable.
Developers focus on product; administrators get clear behavior, not a black box.
zsh — phrony
Spot unusual agent behavior early
Rules can only catch the risks you already know about. Phrony also helps detect unusual behavior, unexpected tool use, and suspicious patterns before they become bigger problems.
Learns what normal looks like
Phrony understands the usual behavior of each agent, so unusual actions are easier to spot.
Finds risks you did not define
Surface unexpected patterns such as strange tool sequences, prompt injection attempts, or behavior drift.
Lets your team decide what happens next
Block the action, send an alert, ask for human review, or turn the finding into a new rule.
Industries
Your agents, governed.
Audit, policy, and oversight included, so you can focus on the decision.

EU AI Act Compliance
Built for the governance layer the EU AI Act requires.
Phrony is the runtime and governance infrastructure for production AI agents. For companies deploying high-risk AI systems in the European Union, Phrony is positioned as a third-party component supplier under Article 25 of the EU AI Act.
Human-in-the-loop
Route the hard calls to a human. Keep the run intact.
Integrations
Connect your stack
Tools, data, and APIs—accessed only through the boundaries you set.
