Brothers!!!

Let me talk about something I both love and hate: Claude Code.

Is it good? Really good. I use it to maintain the python-office project, help me read code, fix bugs, write documentation, saving me I don't know how much time.

But how uncomfortable it is to use, those who know, know——

Accounts get banned one after another
Unstable network, disconnects while using
Pay-per-use, easy to overspend
Every time there's a problem, you have to start over

I've always wanted to ask: Is there a domestic, stable, no-need-to-翻墙 alternative?

On April 18th, I found the answer in Beijing.

I'm Programmer Wanfeng, with 300,000+ followers across platforms, author of the open source project python-office.

🔥 AtomCode, My Real Experience After Using It for a Week

On April 18th, AtomCode held a press conference in Beijing and officially open-sourced.

I went to the scene and used it for a week after coming back, let me share my real feelings.

First, the conclusion:

For simple tasks, it's similar to Claude Code.
For complex tasks, there's still a gap, but the gap is narrowing.
For daily use, it's completely sufficient and much more stable.

💪 Where Does AtomCode Win Compared to Claude Code?

Comparison Item	Claude Code	AtomCode
Open source	❌ Closed source	✅ MIT open source
Domestic models	❌ Not supported	✅ DeepSeek/Qwen/ZhiPu GLM
Token cost	💰 Pay-per-use	🆓 Free for a long time
Network	⚠️ Need 翻墙	✅ Domestic direct connection
Package size	Relatively large	< 50MB
Startup speed	Average	Second-level

Three things that impress me the most:

First, Token is free.

The biggest psychological burden of using Claude Code is: How much did this conversation cost?

AtomCode directly says: Token free for a long time. No need to calculate, use it freely.

Second, Domestic models can be switched freely.

DeepSeek, Qwen, ZhiPu GLM, use whichever you want.

Use DeepSeek for complex reasoning, Qwen for code completion, use whichever works best, true "model freedom".

Third, Local operation, data not uploaded.

Code won't be uploaded to any server. I don't want anyone to see the code of python-office. Local operation makes me feel at ease.

🎯 How Does It Achieve Stability?

AtomCode has three built-in mechanisms:

Mechanism	Function
Forced planning	Think clearly before acting, not easy to deviate
Diagnostic compression	Accurate positioning when errors occur, no random guessing
JSON repair	Automatic repair of format errors, ensuring completion

🚀 Who Is It Suitable For?

Crowd	Description
✅ Those whose Claude Code accounts were banned	Directly switch to AtomCode, much more stable
✅ Python developers	Maintaining projects, writing scripts, processing data, all can use
✅ Beginners wanting to learn AI programming	Chinese interaction, low threshold
✅ Enterprise developers	Local operation, data security

💡 How to Install?

👉 Official website: https://atomcode.atomgit.com
👉 Bilibili demo: https://www.bilibili.com/video/BV1tVoxBfEX7

Supports macOS, Linux, Windows, just enter atomcode in the terminal to use.

💡 Finally

I'm not saying AtomCode has completely surpassed Claude Code.

But for domestic developers, it solves the most core problems: stable, free, no need to翻墙, supports domestic models.

These three points are more important to me than "strongest performance".

Remember one thing: Technology isn't高冷, AI is easy to use. I'm Programmer Wanfeng, follow me to master AI programming!

Go try it, use it for a week, you'll have your own judgment.
