# Omnara > Source: > Published: 2026-10-07 22:36:24+00:00 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.
