There's a project on GitHub Trending this week with an absurd star growth rate.
DeepSeek-TUI—a tool that runs a DeepSeek coding agent in your terminal—gained 20,835 stars in a week.
Meanwhile, a bunch of flashy AI IDE plugins gained a few hundred.
What does this tell us?
Developers Want Speed, Not UI
DeepSeek-TUI's README is short. The functionality is simple: call DeepSeek models to write code in a terminal.
No GUI, no visual diffs, no sidebar chat window, no one-click deploy. Just a black screen with white text. You type, it returns code.
But it's growing faster than every GUI competitor combined.
The reason is simple: for experienced developers, the terminal is the fastest interface.
Switching to mouse, clicking, dragging, resizing windows—these look friendly in a GUI, but in a high-frequency coding scenario, each action is latency. Keyboard to terminal, zero switching cost.
But the Deeper Reason: Terminal Gives Developers a Sense of Control
This is what I find most interesting.
AI coding tools are fundamentally about "ceding control to the machine." You tell it what to do, it writes code.
But the terminal is different. It's an environment where you can precisely control every detail. Pipe, grep, redirect, alias—you know all of these. Putting AI in the terminal means "I retain control of the entire workflow; AI is just one command in it."
This is a completely different mindset from "open an AI IDE and hand everything over to it."
Three Routes in AI Coding This Week
Terminal route: DeepSeek-TUI (27k, +20k this week). Minimal, keyboard-first, developer-friendly.
IDE route: Various AI IDE plugins. Feature-rich, visual, but heavier.
Gateway route: 9router (9.8k, +5k this week). Aggregating multiple models, optimizing cost.
Skills route: agent-skills (40k+). Defining agent capability boundaries.
The terminal route grew fastest this week. Not because other routes are bad, but because it shows a trend: as AI coding tools become homogeneous, "experience differentiation"—especially for power developers—is becoming the biggest competitive moat.
My Judgment
DeepSeek-TUI's explosion isn't about technical superiority. DeepSeek's model isn't stronger than Claude or GPT (at least for coding).
It won on product form.
The terminal is a severely underrated AI product form. Not because it's easy—it has a learning curve, and it's completely unfriendly to non-developers—but because its target audience happens to be exactly the people who need AI coding tools most: heavy developers who spend 6-8 hours a day in the terminal.
A Prediction
In the next year, we'll see more and more "terminal-first" AI tools. Not because they're technically better, but because they tap into a user segment ignored by the GUI-dominated AI product market—veteran developers who don't need to be "treated friendly," just "served efficiently."
Claude Code already proved this path works. DeepSeek-TUI further proves: open source community + terminal + AI = explosive user growth potential.
