Coze: ByteDance's AI agent platform for building and deploying chatbots and agents with built-in plugins, workflows, and multi-platform publishing.
ByteDance's platform for building AI chatbots and agents — create, test, and publish AI bots across multiple channels.
Coze is ByteDance's freemium AI agent development platform in the agent platforms category, offering a free tier and paid Premium plans starting at $9/month, that enables users to build sophisticated chatbots and AI agents without coding and deploy them across 8+ messaging channels from a single workspace.
The platform combines a visual workflow builder, an ecosystem of 60+ built-in plugins, knowledge base management with automated RAG, and multi-platform publishing into a unified development environment. Since its launch, Coze has expanded beyond chatbot building into an intelligent office suite covering AI writing, presentation generation, web development, and AI-assisted design.
The workflow editor is Coze's standout feature — a visual canvas where users chain together LLM calls, conditional logic, code blocks, API calls, and plugin invocations into complex agent behaviors. Unlike simple decision-tree chatbot builders, Coze supports branching, loops, variable passing, and nested sub-workflows, making it capable of handling genuinely sophisticated automations. Users can switch between multiple LLM backends — including GPT-4o, Claude 4.5 Sonnet, and ByteDance's Doubao models — on a per-agent or per-node basis without managing separate API keys.
Coze's plugin marketplace includes 60+ pre-built integrations covering web search, image generation, code execution, data analysis, and popular SaaS tools. Custom plugins can be registered by uploading an OpenAPI specification, with authentication, rate limiting, and error handling managed automatically by the platform. The knowledge base system supports PDF, Excel, TXT, and web page ingestion with configurable chunking, embedding, and retrieval parameters.
One-click publishing to 8+ channels — including Discord, Telegram, Slack, Facebook Messenger, LINE, Lark, embedded website widgets, and mobile apps — sets Coze apart from developer-focused alternatives. Channel-specific UI adaptations for buttons, cards, and file uploads are handled automatically. In 2024, ByteDance open-sourced Coze Studio and Coze Loop, enabling fully self-hosted deployments and production observability for teams with data sovereignty requirements. The platform processes over 100 million bot interactions monthly across its hosted and self-hosted deployments, with an average agent build time of under 30 minutes for template-based projects.

A drag-and-drop canvas for chaining LLM calls, conditional logic, code blocks, API calls, and plugin invocations into agent behaviors. Supports branching, loops, variable passing, and nested sub-workflows, going well beyond the simple decision-tree paradigm of older chatbot builders. This is what lets Coze handle genuinely complex automations rather than just FAQ-style bots.
60+ built-in plugins covering web search, image generation, code execution, data analysis, and popular SaaS integrations. Users can register custom plugins by uploading an OpenAPI specification, and Coze handles authentication, rate limiting, and error handling automatically. This dramatically reduces the glue code typically needed to integrate an agent with external services.
Upload documents, URLs, and structured data and Coze automatically handles chunking, embedding, indexing, and retrieval. Configurable parameters let you tune chunk size, retrieval depth, and similarity thresholds without writing RAG code. Ideal for building domain-specific agents that draw on proprietary knowledge without fine-tuning a model.
One-click deployment to 8+ channels including Discord, Telegram, Slack, Messenger, LINE, Lark, embedded website widgets, and mobile apps. Channel-specific UI elements like buttons, cards, and file uploads are adapted automatically, so the same agent works correctly everywhere. You can also expose any agent as a REST API for custom integrations.
Released in 2024, the open-source versions let teams self-host the agent platform and the evaluation/observability layer. This unlocks deployments where data sovereignty, on-premise hosting, or full customization are required. It also lets developers extend the platform itself rather than being limited to the hosted product's roadmap.
