Omnara

Omnara launched as an open-source agent platform that provides durable state, machine management, access controls, and audit history for teams running AI agents in production, offered free to self-host under the Apache 2.0 license. Omnara positions itself against managed platforms such as Amazon Bedrock AgentCore by letting teams bring their own model keys and machines at no charge, or pay as they go for Omnara-managed resources at provider token rates, and cites engineering teams that spent four months and roughly 100,000 lines of code to ship a single internal agent.

Open Source Alternative to: Stars Last commit Repository age Version License Self-hosted Repository Building a prototype agent takes an afternoon. Getting it to production is where teams burn months. Omnara is an open-source agent platform that handles the hard parts: durable state, machine management, access controls, and audit history. It's aimed at teams that want the speed of a managed agent platform https://openalternative.co/alternatives/claude-managed-agents without handing over control of their models, data, or cloud. Agents in Omnara are durable API objects, not just library calls baked into your app. You launch, steer, and observe them through a REST API, TypeScript SDK, or CLI. That means your application owns the whole experience, and you can run many agents without redeploying code every time something changes. Key capabilities: The comparison to building in-house is stark. Several engineering teams have publicly described spending four months and roughly 100,000 lines of code to ship a single internal agent https://openalternative.co/agenta . Omnara provides that substrate on day one: session management, durable event logs, credential proxying, and observability, without a dedicated platform team. Unlike Amazon Bedrock AgentCore https://openalternative.co/alternatives/amazon-bedrock-agentcore or similar managed platforms, Omnara doesn't lock you to one vendor's models, sandboxes, or pricing. The platform itself is free. You bring your own model keys and machines at no charge, or pay as you go for Omnara-managed resources at provider token rates. Self-hosting under the Apache 2.0 license is fully supported. Every Sunday we deconstruct one proprietary app and pick the best open source alternatives worth switching to.
