Models like DeepSeek and GLM have no web access, or a weak one. ModSearch is a plug-in that greatly strengthens web search, X search, and single-page fetch. It works the moment it lands: the default engine is Firecrawl's keyless tier, 1,000 free credits every month, with no account, no API key, and no card.

Features
- 🥇 The strongest free web search plugin for DeepSeek Harness (dsh): one command installs it,
npx -y @deepseek-ai/dsh plugin --profile web add @liustack/[email protected]. In the desktop app's Add plugin dialog, enter@liustack/modsearch, not the GitHub URL. Details in harness setup. - Free out of the box, no signup. Search and page fetch run on Firecrawl Keyless by default: 1,000 free credits/month, no account, no API key, no card. Every fallback channel is free too: Antigravity CLI needs only a browser sign-in, and Tavily, Exa, and a free Firecrawl key each add their own monthly quota with no card required.
- Automatic failover. When a channel fails or exhausts its quota, the next one takes over.
- Per-engine key rotation. Give Tavily, Exa, Firecrawl, or Keenable multiple comma-separated keys. Authentication, rate-limit, and quota failures rotate to the next key before the engine chain falls back.
- Searches X (Twitter). With Grok Build installed, ModSearch queries the corpus that web indexes cannot reach.
- Install once, use everywhere. Works in Claude Code, Codex, Pi, and OpenCode.

Give it a blog link and ask what the post says. Twenty-five seconds later: a structured summary of the whole post, with no browser involved.
Give it no target at all, just "anything interesting in AI today?". Thirty-six seconds later: six sourced stories, with a closing note on which details came from aggregation and deserve a second look. The note comes from the uncertainty field.
