Clients frequently ask whether Pega is compatible with LangGraph or if it supports multi-agent collaboration including handoff, shared context, and conflict resolution. The answer to both questions is yes, even if the second question refers specifically to Pega’s native support for multi-agent collaboration.
Pega and LangGraph serve very different functions.
Pega: The Enterprise Brain
The Pega platform is designed to automate, manage, and optimize large-scale business processes securely and scalably. It also allows users to incorporate AI agents within these workflows. The main users of Pega Platform are enterprise professionals such as business analysts and IT developers.
Agents within Pega are a mix of human and automated actors working together on a central “case”.
- Shared Context: The Pega Case is the single source of truth, providing a shared context that every agent accessess.
- Automated Agents: Decisioning Rules, Integration Agents or Doc Processing Agents who can process information autonomously
- Human Agents: Business users who are assigned tasks when human judgement or arbitration is needed.
- Handoffs and Conflict Resolution: Pega’s process engine excels at managing handoffs between these agents. If an automated agent flags a risk, the case is automaticaly routed to a human expert. If that expert needs a higher-level decision, the case is escalated to a manager. This entire flow is audited and governed by Pega’s business rules.
Below article explains how Pega enables multi-agent collaboration and shows agent placements in cases and applications.

LangGraph: The AI Mind (The Specialist Agent)
LangGraph is ideal for creating AI-native applications that rely on Large Language Models (LLMs) to power their main logic. It is designed with developers in mind, specifically targeting Python programmers and AI engineers as its primary users. LangGraph enables building autonomous agents with non-deterministic outcomes.
The Synergy Pattern: How the Brain Delegates to the Mind
Paired with Pega, LangGraph allows business to advance toward an Autonomous Enterprise while maintaining transparency and auditability Pega is known for. The integration is achieved through API which is a clean and standard architectural pattern.
The diagram below shows this synergy. It illustrates a sample business process that utilizes both Pega and LangGraph. When a customer initiates a loan request, the enterprise process begins in Pega with an initial data validation check. When the process reaches a step requirinig deep cognitive analysis, like “Perform Due Dilligence”, the Pega “Enterprise Brain” delegrates the task to the LangGraph “mind”. This handshake works in three steps:
- Delegate: Pega bundles the relevant case data and makes Connect-REST API call to a specific end point
- Reason: The LangGraph agent, wrapped in a REST API using a Python web framework like FastAPI, receives the request. Its multi-agent system then executes teh complex task via specialised AI agents for research, synthesis, and analysis
- Resolve: The LangGraph agent sends a structured result (e.g. a risk score and summary) back to Pega, which ingests the data and intelligently moves the case to the next step.
Pega does not seek to replace developer-centric frameworks like LangGraph. Its purpose is to orchestrate the end-to-end business value stream. By integrating specialized AI agents built with LangGraph into the robust, governable workflows managed by the Pega “brain”, organizations can achieve a level of automation that is both intelligent and secure.
