Charlie Labs
Always-on AI agents defined in markdown that work 24/7 across Slack, Linear, and GitHub without prompts.
Key features
- Markdown-Defined Daemons: Author agent behavior in simple .md files that are easy to read, version, and customize.
- Always-On Operation: Daemons run 24/7 and act proactively without requiring explicit prompts each time.
- Multi-Tool Integration: Works across Slack, Linear, GitHub, and more to coordinate tasks where teams already operate.
- Completed-Work Billing: A credit system charges only for finished work like bugfixes, features, or refactors, with PR reviews always free.
- Engineering Automation: Keeps pull requests, issues, CI, and documentation moving so engineers focus on novel problems.
Best for
- PR Maintenance: Keeping pull requests reviewed and moving without manual chasing.
- Issue Triage: Proactively managing Linear and GitHub issues across the backlog.
- Routine Refactors: Shipping small fixes and refactors automatically so engineers focus on harder work.

ZER0 - Unblock Your Agents
Zero
Platform to discover, connect, and use agent services across the internet, unblocking AI workflows and integrations.
Key features
- Service Discovery: A centralized registry and discovery mechanism to find agent services and capabilities across the internet, reducing manual service discovery overhead.
- Unified Connector Layer: Connects disparate agent endpoints through standardized APIs or adapters so applications can invoke remote agents with a consistent interface.
- Secure Access & Authorization: Provides authentication and permissioning controls to gate which agents or clients can call specific services and to record access events for auditing.
- Orchestration & Routing: Routes requests between callers and agent services, enabling composition of multi-step or multi-agent workflows with controlled execution paths.
- Developer Tooling: SDKs, API endpoints, or integration helpers (platform-agnostic) to simplify embedding discovered agent services into applications and prototypes.
- Monitoring & Telemetry: Collection of usage and operational metadata to help track agent performance, errors, and invocation metrics for debugging and optimization.
- Interoperability: Adapters and connectors designed to bridge different agent implementations or hosting environments so capabilities can be reused across platforms.
- Governance Controls: Policy and governance primitives to define allowed behaviors, blocklists, or rate limits for connected agent services.
