Features and specs

What each product offers, as listed by its team.

Omnara 7 features
StackMail 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.
  • Privacy-Focused
    StackMail emphasizes data privacy and security, offering encrypted email services without scanning user data for advertising purposes, appealing to privacy-conscious businesses.
  • Business-Oriented Features
    Designed specifically for businesses, it includes features like custom domain email, collaborative tools, calendars, and contact management tailored for professional use.
  • Competitive Pricing
    StackMail offers competitively priced plans compared to some larger email providers, making it accessible for small to medium-sized businesses.
  • No Ads
    Unlike some free email services, StackMail does not display ads to users, providing a cleaner and more professional email experience.
  • Custom Domain Support
    Users can easily set up email addresses with their own custom domain names, enhancing brand professionalism and consistency.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.

  • Unix philosophy and filesystem access makes Claude Code amazing
