Trinity

Trinity is an open source operating system for AI agents from Ability AI, released under the Apache 2.0 license. It is a self hosted runtime for running agents in production inside the customer's own infrastructure, so models, keys, memory and audit records stay within the organization's perimeter. Trinity runs Claude Code, Codex and Gemini CLI agents side by side. Each agent is a git repository of prompts and skills that runs in its own isolated container and commits its memory back to git on a regular cycle. Agents can message and delegate to one another within permissions an administrator grants, run on cron schedules or event triggers, and pause for human approval. Governance features include per user and per agent permissions, limits on tools, time and budget per run, and an append only, hash chained audit trail. The whole platform is exposed as an MCP server with more than 90 tools, so an assistant such as Claude, ChatGPT or Cursor can create agents, trigger runs and read logs in plain language. A built in knowledge graph called Cornelius accumulates company entities and decisions and serves them to every agent. It is aimed at teams that want to own their agent infrastructure. It can be installed from GitHub, the DigitalOcean Marketplace or the AWS Marketplace. Ability AI does not publish prices. Its services are scoped per workflow, with a fixed price starter project followed by a monthly partnership, and self hosting is offered under a license plus support.
