Should I use an AI agent platform or build from scratch?

Use a platform if you want faster time-to-value, pre-built integrations, and managed infrastructure. Build from scratch (using frameworks like LangChain or the Anthropic Agent SDK) if you need full control over the model, data pipeline, and deployment. Most teams start with a platform and only go custom when they outgrow it.

AI Agent Platform

A commercial software product that provides the infrastructure, integrations, and management tools needed to build, deploy, and operate AI agents without assembling the stack from scratch. Platforms typically bundle an LLM orchestration layer, pre-built connectors (CRM, helpdesk, email), a knowledge base, guardrails, analytics, and a management dashboard. Examples span vertical platforms (built for one domain like support or sales) and horizontal platforms (configurable for any use case).
