Agentok

Agentok Studio is an open source visual builder for multi agent applications on AG2, the agent framework previously known as AutoGen. Users design agent workflows on a drag and drop canvas and the studio generates self contained Python code that runs anywhere as a normal program. It is aimed at developers who want to prototype AG2 conversations visually while keeping full control of the resulting code. Agents are nodes on a diagram, and tools are configured on the edges between them so the model knows which tools to call and which node executes them. A tool editor manages tools with configurable variables, a chat tab runs each flow, and the studio shows the underlying data representation along with the original AG2 logs for debugging. The current release targets AG2 version 1 and emits its newer protocol driven API; some legacy node types from the classic stack are no longer generated, and the earlier RAG feature has been removed. A DeepSeek assistant node and per node model configuration are available. The hosted studio is free to use after signing in with GitHub, Google or email, and the code can be self hosted with a Next.js frontend, a Python API and Supabase for authentication and storage. It is licensed under Apache 2.0 with additional terms and conditions. The maintainers state that the online deployment is not intended for production use, carries no service level guarantee and may have its data wiped after breaking changes. They are also building a new backend framework, VibeX, to replace the current one.
