Open Source vs Proprietary AI Agents: Which Should You Choose?

The open source vs proprietary debate in AI agents mirrors the same debate in databases and operating systems — and resolves the same way: it depends. Open source agents (AutoGen, CrewAI, LangGraph) give you full control over the code, no vendor lock-in, and the ability to run fully on-premise. The cost is real: you need engineering time to build, maintain, and secure the stack. Proprietary platforms (AgentDesk, Salesforce Agentforce, ServiceNow AI Agents) are production-ready out of the box, come with SLAs, and have dedicated support teams. The cost is ongoing licensing and less flexibility. The pragmatic answer: start with a proprietary platform to prove ROI quickly, then migrate specific high-value workflows to open source if cost or control becomes a constraint. Most enterprises run a hybrid.
