# B3OS

How B3OS fits into B3: workflows, actions, triggers, wallets, connectors, Caddie, and the product loop around $B3.

This page explains where B3OS fits inside B3. For implementation details, use the dedicated [B3OS docs](https://docs.b3os.org).

## What Is B3OS?

B3OS is the workflow operating system for crypto-native teams. It connects triggers, built-in logic, onchain and offchain actions, organization-owned wallets, encrypted connectors, execution webhooks, and Caddie-assisted workflow authoring in one product surface.

**[Workflow engine](https://docs.b3os.org/platform/workflows)**

Model triggers, branches, loops, reusable blocks, versioned drafts, public views, and execution paths.
  **[Action library](https://docs.b3os.org/actions/introduction)**

Use typed schemas for blockchain reads, onchain execution, integrations, messaging, utilities, and wallet operations.
  **[Caddie](https://docs.b3os.org/platform/ai-agent)**

Create, repair, inspect, and explain workflows with an AI copilot that understands actions, triggers, templates, org knowledge, and recent run context.

## Where It Fits

| Engine | Role | Contribution to B3 |
| --- | --- | --- |
| B3OS | Workflow platform for onchain apps, automations, wallets, contracts, and integrations. | Generates platform revenue and gives Labs a reusable execution layer. |
| Labs | Product studio shipping consumer experiences such as Bsmnt, HypeDuel, AnySpend, Upside.Win, and more. | Turns product usage and feedback into new B3OS templates, actions, and workflows. |
| Holdings | Strategic investments in businesses that complement the B3 ecosystem. | Expands distribution, revenue surfaces, and product inspiration for B3OS and Labs. |
