The DSH Plugin Ecosystem, One Month In: 14,000 Repos and What's Actually Worth Installing

One month after DeepSeek Harness went open source, we ran our first full index of the dsh-plugin topic on GitHub. This post is what the ecosystem actually looks like from the data — not the hype version.

The headline numbers

• 219,000+ stars on deepseek-ai/deepseek-harness, four weeks after release.
• 14,000+ repositories in the dsh-plugin topic.
• In our first index pass (top ~660 repos by stars and recent activity): 583 verified on-topic, 74 flagged as topic-spam.

That last number deserves attention. Roughly 11% of repos carrying the dsh-plugin tag have no connection to DeepSeek Harness — resume builders, image uploaders, no-code platforms farming a hot topic for visibility. Every auto-scraped directory lists them silently. We flag them.

What people are actually building

Our category breakdown of on-topic plugins:

| Category | Share of index | | ------------------------------- | -------------- | | Agents & workflows | ~22% | | Model providers & routing | ~16% | | Desktop clients | ~13% | | Marketplace & discovery tooling | ~12% | | Themes & skins | ~4% |

TypeScript and JavaScript dominate (~80% of repos with a detected language), with Python a distant third. MIT is the overwhelming license choice (422 of 583 on-topic repos).

Two structural observations:

The ecosystem is extraordinarily fresh. Of the repos we indexed, only 2 hadn't been pushed to in over 30 days — because almost everything is less than a month old. 43 repos in our index were created in the last week alone. "Recently maintained" is currently meaningless as a quality signal; it will start mattering around month three.

Distribution hasn't settled. Only 45 of 583 on-topic repos ship a detectable npm package, and just 12 declare DSH engine compatibility (engines.dsh or an @deepseek-ai/dsh-* peer). Most plugins are GitHub-only source installs with no declared version contract — fine for week four of a preview ecosystem, risky as a steady state.

The plugins that matter right now

From the full ranking, the short version:

• dsh-market — the in-app market that turns discovery into one click, with the most mature security posture we've seen (same-origin-only install endpoint, curated-source restriction, blocked build scripts).
• awesome-dsh-plugin — the curated registry much of the ecosystem builds on.
• open-design, Reasonix, dsh-desktop — the star leaders, each taking "everything is a plugin" in a different direction.
• Themes are the smallest category (~22 repos) but the most community-flavored — led by the Whale Girl skin series, a nod to DSH's "Black Whale" codename.

What we're watching

1. An official web directory. DeepSeek hasn't shipped one. If it does, third-party catalogs survive on trust signals and reviews, not listings.
2. Breaking changes. The preview README promises them. The plugins that declared engine ranges will survive; the other 571 are a support queue waiting to happen.
3. Whether the star curve holds. We track star history daily on 200 repositories precisely so "trending" can't be faked by a one-time spike.

All numbers in this post come from our public index pipeline, refreshed daily — the live version is always on the directory page.
