Coze Studio

Coze Studio is the open-source core of ByteDance's Coze platform, packaged as a self-hostable, all-in-one environment for designing, debugging, and shipping AI agents. The stack ships a visual workflow canvas, a plugin system, knowledge bases, prompt management, a database layer, and an agent runtime, plus an OpenAPI and Chat SDK so you can drop agents into your own products. Backend is Go, frontend is React/TypeScript, and the whole thing deploys via Docker Compose on a 2-core/4GB box.

It sits in the same bracket as Dify, Flowise, and LangFlow but leans heavier on enterprise-grade architecture (DDD, microservices) and inherits patterns from the hosted Coze platform that already serves millions of developers. The open-source edition is Apache 2.0 and free; certain features like tone customization remain commercial-only. Best for teams that want a hosted-Coze experience without the SaaS lock-in and are comfortable wiring up their own model keys (OpenAI, Volcengine, etc.).

Integrations cover OpenAI-compatible models and Volcengine out of the box, with plugin extensibility for third-party services. The README explicitly flags security caveats around public-network deployment (SSRF, code-node Python execution, account registration), so this is a build-it-yourself platform rather than a turnkey hosted service.
