Agenta

Agenta is an open-source workspace for building specialized agents that automate your work. You describe the job in chat, connect the applications the agent needs, and improve it through feedback rather than redrawing a workflow diagram every time the task shifts.

Agents are defined with open standards, an AGENTS.md file, skills, and MCP servers, so anything built for the wider ecosystem carries across. Claude Code, Pi, and Codex work as harnesses today, models can be self-hosted or reached through an API, and self-hosting lets you run agents against an existing Claude or ChatGPT subscription instead of metered billing.

Several pieces turn a single agent into something a whole team can use.

• Shared workspaces: you and your agent work on the same files, writing documents, organizing research, or maintaining a wiki.
• Human approval: permissions are set per tool, so some actions run automatically, some wait for you, and some are blocked outright.
• Background agents: runs start on a schedule or when an event fires in a connected app.
• Tracing and cost: every model and tool call is inspectable, with token usage and estimated cost tracked per agent.
• Integrations: connect through MCP directly, or reach more than 1,000 apps through Composio, including Gmail, Slack, Notion, and GitHub.

Every run is traced and every agent configuration is versioned, so a failure can be compared against the change that caused it. Team sharing and role-based access come with the open-source edition, an installable setup skill walks you through self-hosting, and a hosted cloud version exists for trying it first.
