How Falcon Builder is built
A composable, model-agnostic, governance-aware platform — so agent workflows deploy as real systems: observable, controlled, and scalable.
Core principles
The same four pillars that guide every layer of Falcon Builder.
Modular building blocks
Workflows are assembled from nodes — logic, tools, code blocks, API calls, and LLM invocations. Change one node, not the whole flow.
- Reusable workflow primitives
- Separation of concerns
- Configurable execution paths
Transparent execution
RBAC, audit-ready event trails, and deterministic handling of side effects. Every run is logged and inspectable.
- Policy-aware tool access
- Deterministic handling of side effects
- Audit-ready event trails
BYO LLM
Use OpenAI, Anthropic, or any provider via API key. Falcon Builder never resells tokens or marks up usage.
- No vendor lock-in
- Tokens billed to your provider
- Swap models without rewriting workflows
Lifecycle operations
From free-tier prototyping to 50,000+ executions/month. Long-running workflow support, environment parity, and observability built in.
- Execution logs and run visibility
- Environment parity
- Long-running workflow support
Falcon Builder's three-layer stack
Every workflow runs through three layers: composition, execution, and operations.
Composition layer
Define workflows visually — drag-and-drop nodes for tools, actions, routing, LLM calls, and constraints.
Execution layer
Model calls, tool invocation, error handling, and deterministic side effects — triggered by webhooks, cron, email, SMS, or voice.
Operations layer
Execution logs, run replay, metrics, governance controls, and audit-ready reporting.
