Should I build a custom agent or use one from a marketplace?

Start with a marketplace agent if one fits your use case—it's faster and proven. Customize it as needed. Build custom only when your workflow is unique enough that no marketplace agent covers it, or when you need full control over the agent's behavior, data handling, and integration stack.

A platform where pre-built AI agents, agent templates, and agent components are published, discovered, and deployed—similar to app stores but for autonomous AI workflows. Marketplaces accelerate adoption by letting teams deploy proven agents instead of building from scratch. Examples include Salesforce AgentForce marketplace, HubSpot agent marketplace, and community hubs for open-source agent frameworks.
