Coze Studio: ByteDance's open-source bet on AI agent development
ByteDance open-sourced its Coze agent platform under Apache 2.0; coze-dev/coze-studio hit 18.1K stars and 18.1x growth in Q4 2025.
Coze (扣子, ByteDance)
What the business is
Coze is ByteDance's AI agent development platform — a no-code/low-code visual tool for building, debugging, deploying and operating AI agents with prompts, RAG, plugins and workflow canvases; Coze Studio is its open-source edition.
How it started
ByteDance launched Coze (扣子) in 2023 as an AI agent/bot platform and grew it into a full development platform serving tens of thousands of enterprises and millions of developers. On 2025-07-26 it open-sourced the core under Apache 2.0: Coze Studio (visual agent development environment) and Coze Loop (agent operations and debugging), with commercial-use rights and patent licenses.
What happened
The release hit GitHub Trending almost immediately; the ROSS Index logged coze-dev/coze-studio at 18.1K stars with 18.1x star growth by 2025-10-23, making Coze one of Q4 2025's fastest-growing open-source startups. ByteDance kept the managed clouds (coze.com / coze.cn) as the commercial layer, positioning the open edition against Dify, n8n and LangChain's open stacks, and continued shipping the repo through 2026.
How it ended up
Still running: Coze remains ByteDance's main agent platform; the open-source Studio/Loop repos are maintained and the hosted commercial editions continue to serve enterprises.
Background
Coze is ByteDance's AI agent development platform: a visual, no-code/low-code environment where developers build, debug, deploy and operate AI agents with prompts, RAG knowledge bases, plugins and workflow canvases. On 2025-07-26 ByteDance open-sourced its core under the Apache 2.0 license — Coze Studio (the development environment) and Coze Loop (the operations/debugging platform) — with commercial-use rights and patent licenses.
The bet was that open source, not enterprise sales, would make Coze the default platform for building AI agents. ByteDance had already run Coze as a managed product serving tens of thousands of enterprises and millions of developers; open-sourcing the engine let any team self-host the same stack. The repo reached GitHub Trending quickly, and the ROSS Index logged coze-dev/coze-studio at 18.1K stars with 18.1x growth by 2025-10-23, ranking Coze among Q4 2025's fastest-growing open-source startups.
ByteDance kept the managed clouds (coze.com / coze.cn) as the commercial layer, pitting the open edition against rivals like Dify, n8n and LangChain's open stacks. Chinese developer press covered the release the same week, and the open-source repo has continued shipping through 2026 alongside the hosted product.
What has to be true
- Open-sourcing made Coze runnable anywhere, so developers could try and adopt it without a ByteDance cloud account.
- Apache 2.0 with commercial-use and patent grants removed the licensing fear that blocks enterprise adoption of open-source AI tools.
- The visual workflow, RAG and plugin stack matched what teams already wanted, so the repo converted interest into stars and self-hosters.
- Keeping the managed cloud as the paid layer let ByteDance profit from adoption without charging for the engine.
What can be applied
Open source as a distribution wedge: release a genuinely runnable core, keep the managed cloud as revenue, and let GitHub Trending plus self-hosting — not the sales team — carry adoption.
Aftermath
As of 2026-09-02, Coze Studio and Coze Loop remain live open-source projects under coze-dev, maintained alongside ByteDance's hosted Coze platform; the repo has held roughly 18K+ stars since its Q4 2025 surge (per ROSS Index), and ByteDance continues to ship updates. No shutdown, pivot or sale has been reported; the open edition functions as the community/self-host path while coze.com and coze.cn remain the commercial products.
