Centurian vs AWS AgentCore

[ TL;DR ]

AWS AgentCore is a centralized agent registry inside AWS Bedrock. Cloud-native lock-in by design. Customers want a control plane to escape single-cloud gravity — Centurian is built for fleets that span Bedrock, Foundry, Vertex, Salesforce, and custom code with equal weight. AWS’s revenue motion is data gravity; selling federation contradicts it. AgentCore can govern Bedrock; it cannot govern the rest of your fleet.

Side-by-side

Capability	AWS AgentCore	Centurian
Anchor architecture	AWS Bedrock	Federated, no anchor
Multi-cloud agent governance	No (AWS-only)	Yes
Customer-MCP (Claude Code, ChatGPT, Cursor)	No	Yes
x402 stablecoin per-agent attribution	No	Yes
Two-sided framework marketplace	No	Yes
Trajectory evaluation engine	No	Yes
Neuro-Symbolic Rego enforcement	No	Yes
PLG free-tier solo developer flow	No	Yes

The federation thesis

The reason customers want a federated control plane is to escape cloud-native lock-in. Their fleets already span six platforms. Their compliance officers already inherited 40+ regulatory frameworks. Their finance teams already stitch model-API, MCP, subscription, and stablecoin spend by hand. AWS literally cannot sell the federation pitch without contradicting the data-gravity strategy that drives most of its AI revenue.

FAQ

What is AWS AgentCore?

AWS AgentCore is a centralized agent registry within the AWS Bedrock ecosystem, providing a structured repository for agents, tools, and custom resources with hybrid search functionality. It is designed to tightly couple agent governance with AWS cloud infrastructure. AgentCore is cloud-native lock-in by design — its commercial logic is the inverse of federation.

Why can AWS not match Centurian's federated story?

AWS's revenue motion is data gravity — the more workloads in AWS, the more revenue. Federation lets customers operate across Bedrock, Foundry, Vertex, Salesforce, and custom code with equal weight. Selling the federation pitch contradicts the data-gravity strategy that drives most of AWS's AI revenue. AgentCore can govern agents inside Bedrock; it cannot credibly govern the rest of the fleet.

Does AWS AgentCore track x402 stablecoin spend?

No. AgentCore does not ingest x402 transaction firehoses with per-agent attribution. AWS Cost Explorer + Budgets + AgentCore handle AWS-native spend. Stripe x402, Coinbase Developer Platform, and Cloudflare facilitator streams require an agent-identity-anchored cost data plane, which Centurian provides.

When should you use AWS AgentCore alongside Centurian?

If your AWS Bedrock deployment is large enough that AgentCore is part of your stack regardless, Centurian complements rather than replaces. AgentCore registers and orchestrates Bedrock-native agents inside AWS. Centurian registers and governs all agents (Bedrock + Foundry + Vertex + custom + customer-MCP) on one spine. The bitemporal evidence chain Centurian generates ingests AgentCore activity logs as a source.

Can I move agents off AgentCore once I'm in?

AgentCore's commercial design is anchor-and-deepen. Migration paths are technically possible but commercially discouraged. Centurian's design is anchor-free: agents register via MCP, run in their own runtime, and Centurian observes outcomes. Lock-in by architecture is incompatible with the federated control plane thesis.
