What is Cindy?
Cindy is an open-source AI agent that unifies multiple model harnesses and tools within a single workspace. It lets you switch harnesses and models mid-task while preserving memory, context, skills and tool access.
Cindy orchestrates multi-agent workflows for planning, parallel execution and automated review without restarting work. Local-first workspaces keep files and chat history on the host machine, with isolated change sets, line-by-line review and rollback checkpoints.
Integrations include Slack, GitHub, Jira, SSH and mobile control, and the agent connects to managed services, authorized API keys or local model endpoints. Extensibility comes via reusable skills, MCP tools, plugins and an Apache-2.0 source repository for customization and auditing.
