Coze vs Dify Free AI Agent Comparison: 500 Resource Points/Day vs Unlimited Self-Hosting
Want to build an AI Agent without spending money? In 2026, the two hottest free options are ByteDance's Coze and the open-source platform Dify. One is zero-code and instant, the other is open-source and self-hostable. Which should you choose? I've spent serious time with both, and here's a detailed comparison with real numbers.
TL;DR
Coze: Sign up and go. Zero code. 500 resource points/day free. Best for people who don't want to deal with servers.
Dify: Open-source, self-hostable. Supports 100+ models. Completely free with no call limits if you self-host. Best for people with technical skills.
Free Tier Comparison: The Numbers
Let's get straight to what matters — how much can you actually use for free:
| Feature | Coze | Dify |
|---|---|---|
| Free Model | Cloud free, instant signup | Community Edition self-hosted free; Cloud free tier limited |
| Daily Call Limit | 500 resource points/day (~100-500 conversations) | Self-hosted: Unlimited; Cloud free: 200 calls/month |
| Model Selection | Doubao, Skylark (ByteDance models) | 100+ models (OpenAI, Claude, DeepSeek, Gemini, etc.) |
| Bot/App Limit | Unlimited creation | Cloud free: 5 apps; Self-hosted: Unlimited |
| Knowledge Base | 1GB | Self-hosted: depends on server; Cloud free: 50MB |
| Workflow | Supported, visual drag-and-drop | Supported, visual drag-and-drop |
| Publishing Channels | WeChat, Feishu, DingTalk, Web, API | Web embed, API; self-hosted: any channel |
| Data Retention | 3 days (free tier) | Self-hosted: permanent; Cloud free: 7 days |
| Collaborators | 50 people | Self-hosted: unlimited; Cloud free: 1 person |
| Server Required | No | Self-hosted: yes (2-core 4GB minimum) |
| Paid Plan Starts At | ~$1.40/month (¥9.9) | $59/month (cloud) |
Key difference: Coze's free tier is "ready to use" — 500 resource points daily with no server needed. Dify's free tier splits in two: the cloud version has only 200 calls/month (basically a trial), but the self-hosted Community Edition is completely free with no call limits — you just need your own server.
Ease of Use
Coze: 5 Minutes to Start
Sign up with your phone number → Click "Create Bot" → Give it a role description → Add plugins → Start chatting. Zero code, fully Chinese interface (with an English international version), and tons of templates to start from. Complete beginners can be up and running in 5 minutes.
Dify: 30 Minutes to Several Hours
Dify has two paths:
- Cloud: Sign up for Dify Cloud → Create an app → Configure model → Start using. About 15-30 minutes, but the free tier only gives you 200 calls/month — basically enough for testing only.
- Self-hosted: Get a server → Install Docker → Pull Dify image → Configure environment variables → Launch. Takes 1-3 hours and requires some Linux and Docker knowledge.
If you're a complete beginner, Coze's difficulty is 1/10, Dify Cloud is 3/10, and Dify self-hosted is 7/10.
Feature Deep Dive
Model Support
Coze China version uses ByteDance's Doubao models — decent Chinese capability and fast response times. But you can't connect other providers' models. Want GPT-4o or Claude? You'd need the international version (coze.com), which requires a VPN.
Dify supports 100+ model integrations including the full OpenAI lineup, full Claude lineup, DeepSeek, Qwen, GLM, Gemini, and more. You can assign different models to different apps, or even mix multiple models within a single workflow. This is one of Dify's biggest advantages.
Workflow Orchestration
Both support visual workflows, but with different philosophies:
- Coze workflows are more "beginner-friendly" with rich node types (AI model, conditions, code execution, API calls). Drag, connect, and go. Great for quick automation of simple to medium complexity.
- Dify workflows are more "professional-grade" with two modes: Chatflow for conversational apps and Workflow for automation tasks. Data passing between nodes is more flexible, with variable support and conditional branching.
Knowledge Base / RAG
Coze offers 1GB of knowledge base storage on the free tier, supporting document uploads and web links. Retrieval quality is acceptable for simple scenarios.
Dify's RAG engine is one of its core selling points. It supports multiple document formats (PDF, Word, Markdown, etc.), offers both vector search and full-text search, and lets you customize chunking strategies and retrieval parameters. For high-quality knowledge base Q&A, Dify is clearly superior.
Plugin Ecosystem
Coze has a rich plugin marketplace with search engines, databases, social media integrations, office tools, and more. Most plugins are available on the free tier at no extra cost.
Dify calls its plugins "Tools" — supporting custom API tools and built-in tools. While fewer in number than Coze's marketplace, you can connect any HTTP API, giving you more flexibility.
Publishing & Integration
Coze supports one-click publishing to WeChat Official Accounts, Feishu, DingTalk, web embeds, and more. For users in China, the WeChat ecosystem integration is a massive advantage.
Dify publishes primarily through API and web embeds. The self-hosted version can connect to any channel, but you'll need to build the integration yourself. Getting Dify into WeChat requires extra development work.
Data Security
This is important but often overlooked:
- Coze: Data lives on ByteDance's servers. Free tier retains data for 3 days (paid: 7 days). Conversations are encrypted, but all your data passes through ByteDance's infrastructure.
- Dify Self-hosted: Data stays entirely on your own server, never touching any third party. This is the gold standard for data security.
- Dify Cloud: Data lives on Dify's servers with 7-day retention. Similar to Coze, but Dify is a smaller company with potentially less security investment than ByteDance.
If you're handling sensitive business data or personal information, Dify self-hosted is the safest choice.
Real-World Scenario Comparison
Scenario 1: Customer Support Bot
Coze approach: Create Bot → Upload product docs to knowledge base (1GB is plenty) → Set role prompt → Publish to WeChat. Done in 30 minutes. 500 resource points/day handles 100-500 customer inquiries.
Dify approach: Create Chatflow app → Upload docs → Configure RAG → Connect via API to your support system. Self-hosted has no call limits, ideal for high-volume scenarios.
Verdict: Small-scale support → Coze (fast and simple). Large-scale or customized → Dify self-hosted.
Scenario 2: Automated Content Production
Coze approach: Build a "search trends → generate article → polish and format" workflow. Free tier workflow nodes are sufficient, but 500 resource points may not be enough for bulk production.
Dify approach: Similar workflow in Workflow mode. Self-hosted has no call limits for bulk production. Plus you can use stronger models like GPT-4o or Claude for better content quality.
Verdict: Bulk content production → Dify self-hosted. Occasional use → Coze.
Scenario 3: Personal Study Assistant
Coze approach: Upload course materials and notes to knowledge base → Create study assistant bot → Ask questions anytime. 1GB knowledge base stores several semesters of materials.
Dify approach: Similar flow, but you need to set up a server first. Overkill for a personal study tool.
Verdict: Personal study → Coze. Simple and hassle-free.
Scenario 4: Enterprise Internal Tools
Coze approach: Free tier supports 50 collaborators, good for small teams. But 3-day data retention may be insufficient for business use.
Dify approach: Self-hosted has permanent data storage, unlimited collaborators, and MIT license for commercial use. Perfect for enterprise deployment.
Verdict: Enterprise scenarios → strongly recommend Dify self-hosted.
The Gotchas
Coze's Gotchas
- Opaque resource consumption: 500 points/day sounds like a lot, but complex conversations burn through them fast. Sometimes 20+ rounds and you're done.
- 3-day data retention: Free tier conversation history is purged after 3 days. Export manually if you need to keep records.
- Slow during peak hours: 8-11 PM is noticeably slower on the free tier. Paid users get priority.
- Model lock-in: Stuck with ByteDance models. Can't connect other providers.
- China/International split: Two versions with different models, no data sync between them.
Dify's Gotchas
- Cloud free tier is nearly unusable: 200 calls/month, 5 apps, 50MB knowledge base. Just a trial.
- Self-hosting has a learning curve: Requires Linux and Docker knowledge. Not for casual users.
- Server costs money: Self-hosting is free software, but the server isn't. Minimum ~$5-7/month.
- WeChat integration is hard: Publishing to WeChat requires custom development. Not as easy as Coze.
- Cloud paid tier is expensive: $59/month starting price. Not cheap for individual users.
Decision Tree: Coze or Dify?
Choose based on your situation:
- No technical skills + personal use → Choose Coze
- No technical skills + want to try AI Agents → Choose Coze

Why Not Both?
Coze and Dify aren't mutually exclusive. They work well together:
- Use Coze for user-facing applications (WeChat bots, customer support) — leveraging its WeChat integration and zero-code simplicity.
- Use Dify self-hosted for internal tools and complex workflows — leveraging its multi-model support and data security.
Both are free. No reason to pick just one.
❓ FAQ
Conclusion
Coze and Dify represent two different philosophies for AI Agent platforms:
