AWS Loom: Enterprise AI Agent Platform on Bedrock (Complete 2026 Guide)

By Deepak Bagada, CEO at SaaSNext. I have deployed Loom for AWS in a production-adjacent environment and measured the time savings versus building agent governance infrastructure from scratch.

Enterprise AI agents face a problem that has nothing to do with model quality. The models are good enough. The problem is governance. When an agent acts on behalf of a user, who is it acting as? What resources can it access? What actions require a human in the loop? How do you track cost per agent? How do you discover what agents exist in your organization?

AWS Loom for AWS is the first open-source platform designed to answer all of these questions before they become problems. It is opinionated, AWS-native, and designed for platform engineering teams.

WHAT IS AWS LOOM Loom for AWS is an enterprise-grade platform for building, deploying, and operating AI agents on Amazon Bedrock AgentCore Runtime and AWS Strands Agents. It provides a unified management UI with Cognito-based authentication, scope-based authorization, multi-persona navigation, and full lifecycle management for agents, memory, MCP servers, A2A integrations, and AWS Agent Registry governance.

TOOL: Loom for AWS v1.6.0 (Apache 2.0) Enterprise agent platform for Bedrock AgentCore. GitHub: github.com/awslabs/loom Cost: Free, open-source (AWS infra costs apply)

TOOL: Amazon Bedrock AgentCore Runtime Managed agent runtime for execution. Cost: Pay-per-use (AWS pricing)

TOOL: AWS Agent Registry (Public Preview) Governance catalog with approval workflows. Cost: Included with AWS

THE GOVERNANCE STACK Loom's governance is built on four pillars. First, identity and access: Cognito auth with Entra ID/Okta federation, two-dimensional group authorization (Type + Resource groups), and 21 scopes. Second, human-in-the-loop: four configurable HITL methods including agentic loop hooks, tool context interrupts, MCP elicitation, and harness inline functions with full audit trails. Third, identity propagation: OBO token exchange (RFC 8693) so agents access downstream resources with the user's scoped permissions, not a shared service account. Fourth, governance registry: Agent Registry integration with DRAFT/APPROVED workflow for all agents and tools.

DEPLOYMENT IN 2 HOURS Phase 1 (local, 40 min): Clone awslabs/loom, docker-compose up, test agent creation with SQLite. Phase 2 (database, 40 min): Deploy RDS Postgres in private VPC with RDS Proxy. Phase 3 (full, 30 min): Deploy frontend + backend on ECS Fargate behind ALB with TLS and custom domain.

WHEN WE DEPLOYED THIS When we deployed Loom following the 3-phase guide, the total time from clone to a running production-adjacent deployment was 1 hour 52 minutes. The longest single step was the RDS deployment (25 minutes of waiting for the database and proxy). The identity federation setup (Entra ID) took an additional 30 minutes. The first agent creation via the management UI took 5 minutes.

HONEST LIMITATIONS

1. (significant risk) No AWS support: Loom is community software in AWS Labs. No SLAs or support guarantees. Mitigation: Fork and customize for production. Treat as a reference architecture.
2. (moderate risk) AgentCore limits: AgentCore Runtime has specific concurrency and execution duration limits. Not all agent architectures work within constraints. Mitigation: Review AgentCore limits before designing agent architectures.
3. (moderate risk) Breaking changes: Loom is actively developed. v1.x may include breaking changes. Mitigation: Pin to specific releases. Test upgrades in staging.

FAQ Q: How much does Loom cost? A: Loom is free and open-source (Apache 2.0). The AWS infrastructure it deploys (ECS Fargate, RDS, ALB, Cognito) has standard AWS costs. A production deployment serving 50-100 users costs approximately $500-1,500/month in AWS services. Q: Can I use Loom without AWS? A: No. Loom is deeply integrated with AWS services (Cognito, ECS, RDS, Bedrock, AgentCore). Migrating to another cloud provider would require significant reimplementation. Q: Does Loom support custom agent frameworks? A: Loom currently deploys agents via AWS Strands Agents with a standard agentic loop. Support for alternate frameworks (LangChain Deep Agent, OpenDevin) is documented as an open issue on GitHub. Q: Is Loom production-ready? A: Loom is provided as-is without warranties or SLAs. It is functional and has been deployed by the author. Organizations should conduct their own security reviews and testing before production deployment. Q: What identity providers are supported? A: Cognito (built-in), Microsoft Entra ID, Okta, Auth0, and any Generic OIDC provider via Authorization Code + PKCE flow with configurable group claim mapping.
