Rent the cattle, or keep the herd at home. Anthropic's Claude Managed Agents is a managed API for defining agents and letting Anthropic operate the sandbox, state, tools, and credentials. Orbi is a self-hosted GitHub delivery system. Both can turn intent into work; the ownership boundary is different. Every factual claim below carries a source and date.
Claude Managed Agents is Anthropic's managed Agent API: a developer defines the system prompt, tools, permissions, and MCP connections, while Anthropic operates the sandbox, state management, tool orchestration, credential storage through Vault, and error recovery. Its architecture is described as three layers: a stateless, replaceable Brain for reasoning; a one-shot Hands sandbox for execution; and a Session append-only event log as the persistent layer. The service launched on 2026-04-08. and the service is API-triggered rather than a scheduler or messaging integration.
The pricing model combines standard Claude token rates with time spent in a session: Sonnet 4.6 is listed at $3 per million input tokens and $15 per million output tokens, plus $0.08 per session-hour, metered in milliseconds and excluding idle time. Web search is $10 per 1,000 searches. This is a clear published unit, but Anthropic controls both the model price and the capacity available to the service.
Managed Agents puts the cattle in Anthropic's cloud and rents them by the hour. Orbi keeps the delivery line on your machine, uses GitHub as its pasture, and lets you choose the model.
DIFFERENCES THAT DECIDE THE CHOICE
Where Orbi and Managed Agents differ
Dimension
Orbi
Claude Managed Agents
Runs where
Your machine; code, keys, and state stay on your infrastructure
Anthropic cloud sandboxes, with credentials stored in its Vault
Task entry
GitHub Issue + ai-ready label; native scheduling through the task pool
API trigger; no built-in scheduler or messaging integration
Models
BYOK: any OpenAI-compatible endpoint; provider terms vary
Claude only; Brain is Anthropic's replaceable reasoning layer
State
GitHub Issues, labels, branches, PRs, and local run evidence
Append-only Anthropic Session event log
Cost
Your hardware and model; no $/session-hour or platform fee
Claude token prices + $0.08/session-hour; web search $10/1,000
Auditability
AGPL-3.0 open-source code and GitHub-native evidence are inspectable
Managed service; implementation and infrastructure are Anthropic's
A managed service can be the right operational choice, but it puts price, capacity, model availability, data handling, and account continuity inside the vendor relationship. Anthropic can change token or session rates, allocate capacity, or set access policy. Vault isolates credentials inside Anthropic's infrastructure, but code and task context still pass through that infrastructure. Orbi makes the opposite trade: you operate the machine and integrations, while avoiding Anthropic-specific pricing, model, and access dependence.

AN HONEST READ
Which one should you choose?
CHOOSE MANAGED AGENTS IF
You want Anthropic to operate the agent runtime
Agent capability belongs inside your product and an API trigger fits your system
You accept Anthropic cloud execution, Claude-only model choice, and its pricing
Managed sandboxing, sessions, credentials, orchestration, and recovery are worth not operating yourself

Own the delivery boundary
Anthropic can be the right home for a product-embedded Claude agent. Orbi is the right home when the machine, model, and evidence need to remain yours.
