Omnara offers open-source alternative to managed AI agents

A developer has released Omnara, an open-source platform for building and managing AI agents — programs that can independently carry out tasks using tools like web search, shell commands, and file editing ¹. This project presents itself as an option that can be self-hosted, serving as a replacement for both Claude Managed Agents and OpenAI's Agents API .

Omnara works by letting developers define an agent's configuration in a simple YAML file. The config specifies which model to use, what tools the agent can call, and which computer or sandbox the agent should run on ¹. The platform then handles the rest: executing the agent loop, streaming events back to the developer, and persisting every step in a database so agents can recover after a crash .

How it runs

The system has three main parts. An API receives requests to launch agents and send messages. Workers — stateless processes that call the model and run tools — pick up agents from a Postgres database and execute them ¹. A machine daemon runs on whichever computer the agent needs, connecting outbound so no inbound ports are required .

For those who prefer not to manage infrastructure, Omnara also offers a cloud version at app.omnara.com, which provides a preconfigured setup with a model provider and a pool of managed sandboxes ready to use immediately ¹.

Supported models and tools

Omnara supports bringing your own keys for OpenAI, Anthropic, OpenRouter, Amazon Bedrock, LiteLLM, and Ollama, as well as any self-hosted model endpoint ¹. Built-in tools include shell commands, file operations, web search, and web fetching .

Why it matters

Managed agent platforms from major AI companies give developers a quick way to build autonomous AI assistants, but they lock you into proprietary ecosystems ¹. Omnara lets the same kind of agent workflows run on any model and any machine, with the option to host everything yourself . The project is released under the Apache 2.0 license, meaning it can be freely used, modified, and distributed .

The GitHub repository is available at github.com/omnara-ai/omnara, with documentation, a Discord community, and a quickstart guide for getting started ¹.
