The race to dominate developers’ terminals has a new viral contender. DeepSeek-TUI is a terminal-based open source clone of Anthropic’s Claude Code built on DeepSeek models. It has skyrocketed in popularity on GitHub, amassing over 5,000 stars in a matter of days.
-
DeepSeek-TUI, a Claude Code clone, gained 5,000+ GitHub stars in days after its creator promoted it to the Chinese DeepSeek community.
-
The tool offers Claude Code's functionality at a fraction of the cost using DeepSeek's cheaper AI models.
-
Its viral growth reflects developers' preference for open, low-cost alternatives over proprietary coding assistants.
Built by developer Hunter Bown, DeepSeek-TUI describes itself as a coding agent for DeepSeek models that runs in your terminal, positioning it as a low-cost, open alternative to the growing crop of proprietary AI coding assistants currently dominating software development workflows.
What sets this tool apart from a standard wrapper is its deep integration with DeepSeek’s reasoning capabilities. When a developer issues a complex command, the tool enters a "thinking mode" to analyze the codebase.

While the project had its first release in late January 2026, it didn’t get much traction until the release of DeepSeek V4. Soon after the release, Brown tweeted about his project in Chinese, asking the DeepSeek community to help spread the word, and that’s when developers started pouring in.
“This has been the craziest 2 days of my life,” tweeted Brown as the project gained popularity.
Why developers are paying attention
The tool allows developers to chat with DeepSeek models directly from their terminal, edit files, run shell commands, manage tasks, and even coordinate sub-agents across a codebase.
According to its official documentation, DeepSeek-TUI can “read and write files, run shell commands, search the web, manage tasks, and coordinate sub-agents – all with configurable approval gating,” giving it functionality that mirrors more established commercial tools.
The rapid momentum on GitHub reflects a broader shift taking shape across AI-assisted development, with developers increasingly craving more control, transparency, and lower operating costs.
While proprietary systems like Claude Code have set the standard for terminal-native coding agents, they typically require paid API access and operate within closed ecosystems. DeepSeek-TUI flips that equation by leaning on DeepSeek’s low-cost model stack, which offers a similar workflow at a fraction of the cost.
In fact, that cost advantage has become one of DeepSeek’s biggest draws. The Chinese AI company has gained traction by delivering coding and reasoning performance that many see as fairly competitive with Western frontier models, all the while keeping inference costs dramatically lower.
That pricing pressure is now helping fuel an ecosystem of third-party tools built specifically around DeepSeek.
FAQ
Is Claude Code free?
No, Claude Code is not free. It requires either a Claude Pro subscription at $20/month or a Claude Max subscription at $100-200/month. However, you can use workarounds like routing it through free API providers (Google AI Studio, OpenRouter) or running local models to access similar functionality without paying.
Why does Claude Code freeze?
Claude Code freezes mainly due to large file processing (files over 1MB exceed memory limits), network connectivity issues between your system and Claude's servers, or terminal buffer overflow when handling large amounts of output.
Is Claude Code different from Claude?
Yes, Claude Code is different from regular Claude. Claude (the web/chat app) generates text and code suggestions that you must manually copy and implement, while Claude Code is a terminal-based tool that directly accesses, edits, and executes files on your computer.
