Features and specs

What each product offers, as listed by its team.

Omnara 7 features
Rectangle 5 features
  • Unified agent API
    Create, configure, and interact with AI agents through a standard API. Integrate agents into your applications without building a separate agent management layer.
  • Durable execution and state
    Preserve agent sessions and conversation history so work can resume after interruptions without depending on a single running process.
  • Bring your own models
    Use built-in support for any model from model providers like OpenAI, OpenRouter, Anthropic, and Amazon Bedrock with the option to bring your own API key. Or connect any compatible LLM endpoints. Choose the models that fit your needs without being restricted to one provider.
  • Bring your own machines and sandboxes
    Connect local computers, cloud VMs, or any environment capable of running Omnara’s lightweight daemon. Access supported sandbox providers through Omnara or bring your own provider API keys.
  • Custom tools, skills, and MCP integrations
    Equip agents with your own instructions and capabilities, and connect the services they need to complete tasks.
  • Managed hosting or self-hosting
    Use Omnara’s hosted service or deploy the open-source control plane in your own cloud or on-premises environment.
  • Serverless agent architecture
    Keep agent state independent of execution compute, without maintaining a dedicated, always-on server for every agent.
  • Ease of Use
    Rectangle offers an intuitive user interface that makes window management straightforward and user-friendly.
  • Customizable Shortcuts
    Users can easily configure keyboard shortcuts to better suit their workflow, making window management faster and more efficient.

  • Lightweight
    Rectangle is a lightweight application that doesn't consume many system resources, ensuring smooth performance even on older Macs.

Possible disadvantages

  • Limited Advanced Features
    Rectangle lacks some of the more advanced features found in paid window management applications, such as multiple monitor support and more complex window arrangements.
  • MacOS Only
    Rectangle is only available for macOS, so users of other operating systems are unable to take advantage of its features.
  • Occasional Bugs
    Some users report occasional bugs or unpredictable behavior, which might require troubleshooting or waiting for a future update.
  • Learning Curve for Shortcuts
    While customizable shortcuts are a benefit, there is an initial learning curve for users to memorize and effectively use these shortcuts.
  • Basic Aesthetic
    The app's design and aesthetic are quite basic, lacking the polish and visual appeal found in some other similar tools.
