Twelve Days That Grew a Heatmap
On August 22, 2026, the fastest-growing project on the DeepSeek Harness leaderboard was not the official project.
It was a desktop client released twelve days earlier.
deepseek-harness-desktop: +1,059 stars in a day, 17.3k total. Built by Anywhere Labs. First contributor: Tianyi Cui, one of the official DeepSeek Harness authors.
A leaderboard reads like a heatmap. Every star is a degree of temperature. Twelve days ago this board had one row. On August 22 it had an ecosystem.
Day 1: Two fires, one author
DeepSeek Harness was open-sourced on August 13, 2026. Six days later, it had 165,000 stars.
On the same day, Anywhere Labs shipped deepseek-harness-desktop.
Its first contributor is Tianyi Cui (tianyicui) — author of the competitive programming classic Knapsack Problem: Nine Lectures (pack, 2,614 stars). Zhejiang University. Formerly Jane Street. Joined DeepSeek AI in March 2026.
One person writes the official harness. The same person builds the community desktop client. The boundary between "official" and "community" never existed on day one.
The board fills in
By August 22, four of the five fastest-growing projects were ecosystem infrastructure, not models:
- deepseek-harness-desktop — the desktop client, +1,059
- awesome-dsh-plugin — a bilingual plugin directory
- Cordis — a hot-plug plugin runtime from the Koishi.js lineage
- dsh-web-ui — plugin and skin collections
The model itself dropped out of the race. What users starred was GUI, plugin markets, runtimes, skins.
The desktop team's line: "everything is a plugin — the desktop itself is a plugin."
Memory, vision, design
The board also shows where the ecosystem is headed.
Memory: agentmemory, 27,233 stars — persistent memory for AI coding assistants. memos, 10,873 stars — a self-evolving memory OS, claiming 35.24% token savings.
Vision: modlens, 3,495 stars — the first visual plugin for DeepSeek Harness. A text-only assistant learning to see.
Design: open-design, 90,033 stars, first on the all-time board. An open-source Claude Design alternative, local-first desktop app, exporting HTML, PDF, PPTX, MP4. Number one overall, number three in growth — both stock and velocity at once.
The big companies are watching
DeerFlow (ByteDance) holds 80,462 stars. Version 2.0 is a ground-up rewrite on LangGraph and LangChain — filesystem, memory, skills, sandbox-aware execution, sub-agents.
The commercial hook is direct: Volcano Engine's Coding Plan recommends Doubao-Seed-2.0-Code, while supporting DeepSeek v3.2 and Kimi 2.5.
Open source builds the ecosystem. The cloud plan collects the usage.
What the heatmap says
Three trends, each with a number behind it:
- Agents leave the terminal — desktop, web UI, mobile interfaces take the growth board.
- Memory and vision are the new battleground — agentmemory, memos, modlens on the same board.
- Design is the next breakout — open-design at 90,033 stars.
Twelve days ago: one repository. Today: a board with its own direction.
When an ecosystem grows a leaderboard, it is alive.
