Agenta Open-Source Agent Workspace

Agenta is an open-source, MIT-licensed workspace for building, improving and sharing AI agents and LLM applications, operated by Agentatech UG (haftungsbeschränkt), whose imprint lists a Berlin address. It addresses the problem of managing prompts, tests and traces for agents across teams. The company announced Agenta 2.0 in July 2026 and ran its second launch week in November 2025.

Users describe the job in chat, add context and tools, and refine agents from real runs. Prompts, skills and tools are versioned like code with rollback, changes are evaluated against test sets with LLM-as-a-judge or custom evaluators, and each run is traced step by step with cost. Agents run on schedules or app events, with human approval before consequential actions.

• Chat-based building: describe the job, add context and tools, improve agents from real runs.
• Versioning: prompts, skills and tools are versioned like code with rollback to any revision.
• Evaluation: tests changes against a test set using LLM-as-a-judge or custom evaluators.
• Tracing: shows every step of a run, its cost and where it failed.
• Scheduling and approvals: agents run on a schedule or event, with human approval for consequential actions.
• API access: REST API (US, EU or self-hosted), Python SDK and an OpenAPI 3.1 specification.

A Vietnamese e-commerce team can build a scheduled agent for order follow-up with human approval before refunds. A bank innovation lab can version and test chatbot prompts before deployment. A software house can self-host Agenta for several client projects.

The open-source edition is free with unlimited users and agents when self-hosted. Hosted plans start at $0 (Hobby), with Starter at $29 per month and Business at $299 per month. Evaluating changes against test sets before shipping reduces regressions. Human approval gates limit risk from consequential agent actions.

Companies are moving from single prompts to scheduled, tool-using agents, which raises the need for versioning, evaluation and approval controls. Open-source, self-hostable workspaces with a EU cloud region suit Vietnamese firms that want data control and low licence cost.
