webctx

webctx is a pure Go CLI for agent-friendly web search and page extraction.

What it does

• search: combines Brave, Tavily, and Exa search results, deduplicates them, and re-ranks them
• read-link: returns clean markdown for a single URL using a GitHub raw-content path, a .md fast path, and Firecrawl scraping fallback
• map-site: returns a sitemap-style list of URLs and metadata from Firecrawl

Install

Global npm install:

npm i -g webctx
webctx --help

Build from source:

git clone https://github.com/amxv/webctx.git
cd webctx
make build
./dist/webctx --help

Commands

webctx --help
webctx --version
webctx search <query> [--exclude domain1,domain2] [--keyword phrase]
webctx read-link <url>
webctx map-site <url>

Examples:

webctx search "next.js server components"
webctx search "react hooks" --exclude youtube.com,vimeo.com
webctx search "drizzle orm" --keyword "migration guide"
webctx read-link https://docs.example.com/guide
webctx map-site https://example.com

Environment variables

The CLI loads .env.local when present and reads provider credentials from the environment.

Quick start:

cp .env.local.example .env.local

Required by command:

• search
  • BRAVE_API_KEY
  • TAVILY_API_KEY
  • EXA_API_KEY

Release and distribution

This repo publishes in two ways:

• GitHub Releases for native binaries
• npm for npm i -g webctx

The release workflow triggers on v* tags and does the following:

1. runs Go and Node quality checks
2. builds cross-platform binaries
3. creates a GitHub Release with those assets
4. publishes the npm package using the tag version

Project layout

• cmd/webctx/main.go: CLI entrypoint
• internal/app/: CLI parsing, search, ranking, scrape, and Firecrawl queue logic
• internal/buildinfo/: build-time version plumbing for --version
• bin/webctx.js: npm shim that invokes the packaged native binary
• scripts/postinstall.js: downloads the release binary on install and falls back to local go build
• .github/workflows/release.yml: tag-driven release pipeline
• AGENTS.md: guidance for coding agents
• CONTRIBUTORS.md: maintainer/release notes
