Daemons by Charlie Labs
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.
- Docs Upkeep: Keeping documentation in sync as code and issues change.
InstaVM
InstaVM
Production sandbox and control plane to run AI agents as isolated, observable, and controlled microVM servers.
Key features
- Firecracker MicroVMs: Runs agents inside Firecracker microVMs with sub-200ms boot times to deliver near-instant isolated execution environments for short-lived or bursty agent workloads.
- Production Control Plane: Provides server-like controls for agents including lifecycle management, restart policies, and operator workflows so agents can be run and managed like production services.
- Persistent Snapshots & Sessions: Snapshot and restore VM state and agent sessions to reproduce behaviors, debug failures, and roll back to known-good states for deterministic troubleshooting.
- Access & Egress Controls: Fine-grained controls for SSH access, network egress, and resource shares to limit what agents can access and monitor outbound communications for safety and compliance.
- CLI and SDK Integrations: ships a CLI and Python SDK for orchestration-heavy tasks and operator workflows, enabling automated creation, orchestration, and monitoring of agent VMs.
- Skills & Plugin Surface: Provides an installable skill (use-instavm) and integrations with Claude Code and other agent marketplaces to allow agents to leverage VM capabilities (storage, snapshots, SSH) from skill frameworks.
- Local Sandbox for Autonomous Workflows: Supports frameworks (e.g., clickclickclick) for enabling autonomous Android and desktop automation under controlled, reproducible environments.
