DeepSeek-powered Claude Code clone explodes in popularity on GitHub

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.

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.
