Overview
Reliable AI Apps Are Hard
To build scalable AI apps that handle failure and interruptions, maintain state, and coordinate reliably, developers must manage complex infrastructure:
State Management
External databases and serialization
Fault-Tolerance
Custom recovery and retry logic
Interaction Coordination
Queues, orchestration, exactly-once execution
This complexity shifts focus from app logic to managing code and infrastructure for reliability and coordination.
The Golem Alternative
Golem simplifies architecture by building reliability into its core environment:
Automatic Logging
Every state change, API call, and agent action is logged transparently for recovery and insights
Deterministic Replay
After interruptions, logged operations replay deterministically to restore agent state precisely on any node
Resilient Interactions
Golem auto-detects failures in interactions with external APIs and tools and retries them transparently
Exactly-Once Interaction
Guaranteed exactly-once internal messaging and interaction, ensuring no duplicate or lost work
The Golem Execution Lifecycle
Without compromising elasticity or security, Golem ensures flawless reliability and durable state throughout the lifecycle of your agentic services:
1. Deploy an Agent Type
Deploy your agent logic as a reusable, secure unit on Golem’s WebAssembly-based runtime

2. Create Agent Instances
Run any number of isolated agent instances, each with independent, oplog-backed durable state
3. Automatic Operation Logging
Every action—state changes, I/O, API calls—is automatically logged for recovery and insights
4. Seamless Failure Recovery
After interruptions, Golem reassigns the agent, replaying the oplog to restore the exact state

5. Transparent Resumption
Your agent resumes precisely from where it left off—no lost state, no duplicate work, no extra code
Example
This code snippet shows how Golem simplifies building a stateful, resilient AI apps.
State persistence, failure and interruption recovery, retries, and exactly-once handoffs are automatic, letting you focus on logic, not infrastructure.

Golem’s architecture delivers reliable execution, orchestration, and persistent state for AI agents, tools, and workflows.
Core Components
Golem relies on four integrated components:
Shard Manager (Supervisor)
- Monitors node health with heartbeats
- Reassigns tasks on node failure
- Syncs recovery across components
Agent Executor
- Executes logic in isolated sandboxes
- Logs I/O for reliable recovery
- Suspends idle agents, saving state
WebAssembly Runtime
- Runs deterministic logic consistently
- Supports agents in multiple languages
- Isolates execution for added security
Persistent Operation Log
- Records operations for recovery
- Ensures durability with replication
- Aids debugging with logged data
Capabilities
Durable Execution & Fault Tolerance
Golem guarantees reliable execution of agentic services, even in unstable environments
Automatic State Persistence
Internal state automatically persisted—no databases, checkpointing, or manual serialization.
Transparent Failure Recovery
Seamlessly recover from node crashes and infrastructure failures without lost progress or manual intervention.
Reliable External Interactions
API calls (HTTP, gRPC) automatically retry until successful.
Exactly-Once Communication
Built-in guarantees ensure agentic services never miss or duplicate tasks.
Debugging & Observability
Advanced debugging and observability tools provide complete visibility into execution:
Complete Execution Tracing
Inspect every I/O operation, state change, and event timeline.
Real-Time Monitoring
View active agents, their status, resource consumption, and interactions.
Detailed Error Visibility
Quickly identify the exact point of failure and replay execution deterministically.
Integrated Logging & Metrics
Seamless integration with existing observability and monitoring stacks.
Scalability & Resource Efficiency
Golem efficiently supports massive agent workloads through intelligent resource management:
Suspend & Resume Execution
Idle agentic services automatically suspend, freeing resources completely.
Dynamic Resource Scaling
Adjust infrastructure dynamically in response to demand.
Locality-Aware Placement
Optimizes instance distribution for reduced latency and cost.
Resource Efficiency
High-density execution lets thousands of agentic services run efficiently per node.
Security & Sandboxing
Golem executes agentic instances in secure, isolated environments, minimizing risk and increasing reliability:
WASM-Based Sandboxing
Each agentic instance runs securely in an isolated WASM environment.
Capability-Based Security
Agentic services access only explicitly permitted resources.
Fine-Grained Permission Model
Precisely control agentic interactions and communication paths.
Controlled External Access
Monitor and manage agentic interactions with tools and external APIs securely.
Collaboration & Communication
Build multi-agent systems and coordinating agentic workflows with seamless, reliable communication:
Exactly-Once Communication
Guaranteed message delivery prevents duplicates or lost tasks.
Agent Teams
Enable specialized agents to reliably coordinate complex workflows.
Reliable Task Delegation
Delegate tasks between agents or specialized tooling reliably.
Long-Running Collaborations
Agents collaborate continuously over extended periods without loss of context.
AI Tooling & API Hosting
Golem provides the foundation to run not only AI agents and workflows but their entire ecosystem reliably:
