heym
Build agentic systems. Run them with confidence. Orchestrate agents, automate business processes, inspect every execution, and keep humans in control. Deploy Heym on your own infrastructure.
Bottom line: Heym is a powerful tool for agent orchestration, but safety depends heavily on how you configure permissions, isolate the network, and audit agent behavior—a mistake in setup could give agents or attackers access to critical systems and data.

What it does
Heym is a platform for building and running agent systems—AI tools that can take actions on their own. It lets you orchestrate multiple agents, automate business workflows, see exactly what each agent does during execution, and maintain human oversight. You can deploy it on your own servers rather than using someone else's cloud.
Who it’s for
Teams building AI agent systems who want visibility and control over agent behavior, and organizations that need to run agents on their own infrastructure for security or compliance reasons.
Copy-paste setup
Check these steps against the project’s own instructions before running anything.
Follow the project's README at https://github.com/heymrun/heym (opens external site) for installation and configuration instructions specific to your deployment environment.
Risks
- Agent permissions: Agents you deploy can access any data or systems they're connected to, potentially exposing databases, APIs, or files if misconfigured.
- Prompt injection: Malicious input fed to agents could trick them into performing unintended actions or leaking sensitive information.
- Execution transparency gaps: While Heym aims to show what agents do, complex agent chains might still hide harmful actions in subtle ways.
- Infrastructure exposure: Self-hosted deployments put the burden on you to secure servers, networks, and access controls—misconfiguration could expose the entire system.
- Third-party integrations: Any external services or APIs agents connect to become attack surface and data leakage points.
How to stay secure
Least-privilege permissions
- Give agents only the minimum permissions they actually need for their tasks.
- Use service accounts with restricted API keys and regularly rotate credentials.
Network isolation
- Run Heym and agents on isolated networks or containers separate from production systems.
- Use firewalls to limit outbound connections agents can make.
Monitoring
- Log all agent executions and decisions in a centralized, immutable audit trail.
- Set up real-time alerts for unusual agent behavior or permission escalation attempts.
Red flags to watch for
- Agents making unexpected external network calls or accessing unauthorized data sources.
- Execution logs that are missing, unclear, or seem to hide agent reasoning steps.
