BYOC vs. self-hosted for AI agent integrations

AI agent integration platforms require secure handling of credentials, business data, tool execution, logs, network access, and recovery processes, making their deployment model an important architectural and compliance decision. Vendor-managed bring-your-own-cloud (BYOC) places the platform in a customer’s cloud account while the provider manages deployment, upgrades, monitoring, scaling, and platform incidents, whereas self-hosting places both the infrastructure and operational responsibility with the customer’s team. Although both models can keep core services, credentials, and execution within a customer-controlled environment, organizations must verify the complete architecture because local MCP servers or SDKs may still rely on hosted authentication, storage, telemetry, or execution services. The choice affects data residency, vendor access, update control, private-network connectivity, logging and backup policies, costs, and the ability to recover safely from partial or uncertain API operations. BYOC is suited to organizations needing cloud-account control without operating the platform themselves, while self-hosting is more appropriate where vendor access is restricted or teams require direct control over releases and configurations but can support ongoing operations. The comparison highlights enterprise offerings from Nango, Paragon, Arcade, and Composio, noting that Nango provides both managed BYOC and self-managed full-platform deployments, while its free self-hosted edition covers only authentication and proxy capabilities rather than agent tools, syncs, triggers, and MCP functionality.
