sbot  Simple Archiver Bot -- a suckless web archiver written in C. sbot creates self-contained archives of web pages and entire websites.Every resource -- CSS, images, fonts, scripts -- is fetched and inlineddirectly into the HTML as base64 data URIs. The result is a single file(or directory of files) that renders perfectly offline, with no externaldependencies, forever.  WHY   Web pages disappear. Link rot is real. The average web page has a  half-life of about two years. Bookmarks break, articles vanish,  references evaporate.   sbot solves this by creating archives that are:   - Self-contained. Everything is inlined. No external requests needed.  - Human-readable. Output is standard HTML. Open it in any browser.  - Permanent. No database, no server, no special viewer. Just files.  - Metadata-rich. GWTAR headers record provenance, date, and source.  MODES   SINGLE PAGE ARCHIVE     sbot https://example.com/article     Archives a single page in GWTAR format (Gwern Web Tar Archive). This    is the default mode and the most common use case. The output is one    .gwtar.html file containing:     - A GWTAR metadata header (HTML comment) with title, source URL,      domain, author, archive date, and generator version    - The full HTML with all CSS stylesheets inlined as style blocks    - All images, fonts, and media encoded as data: URIs    - A completely self-contained document that renders identically to      the original     GWTAR format is ideal for:     - Archiving individual articles, blog posts, and essays    - Preserving references and citations    - Building a personal web archive / digital library    - Saving pages before they disappear behind paywalls or get deleted    WHOLE SITE ARCHIVE     sbot -r https://example.com     Recursively crawls an entire website and archives every page. The    output is a directory tree that mirrors the site structure, with each    page saved as a self-contained HTML file. Internal links are rewritten    to relative paths so navigation works offline.     Features:     - BFS crawl order. Breadth-first traversal ensures important pages      (closer to root) are archived first.    - Same-domain only. Never follows links to external sites.    - robots.txt compliance. Respects Disallow rules and Crawl-delay      directives by default. Override with -R.    - Depth control. Set maximum crawl depth with -d to limit scope.    - Rate limiting. Configurable delay between requests to be polite to      servers (default: 1 second).    - Progress reporting. Periodic status lines showing pages archived,      queue depth, and elapsed time.    - Graceful degradation. Failed resources are skipped; the crawl      continues.     This mode is ideal for:     - Archiving entire blogs or documentation sites    - Creating offline mirrors of reference material    - Preserving small-to-medium websites wholesale    - Building browseable offline copies of sites you depend on  USAGE   usage: sbot [-vrR] [-d depth] [-o dir] [-a author] url     -v          verbose output    -r          recursive (crawl entire site)    -R          ignore robots.txt    -d depth    max crawl depth (default: 5)    -o dir      output directory    -a author   site author name    EXAMPLES     Archive a single article:      sbot https://example.com/blog/post     Archive with author metadata:      sbot -a "John Doe" https://example.com/article     Crawl a blog, max depth 3:      sbot -r -d 3 https://blog.example.com     Verbose crawl to custom directory:      sbot -v -r -o ./my-archive https://docs.example.com     Crawl ignoring robots.txt restrictions:      sbot -r -R https://example.com  GWTAR FORMAT   Every archived page includes a GWTAR (Gwern Web Tar Archive) metadata  header as an HTML comment at the top of the file:     <!--    ================================================================      GWTAR ARCHIVE    ================================================================       Title:        Example Article      Source URL:   https://example.com/article      Domain:       example.com      Author:       John Doe       Archived by:  Kris Yotam      Archived on:  krisyotam.com      Archive date: 2026-02-14       Generator:    sbot/0.3.0      Format:       GWTAR (Gwern Web Tar Archive)     ================================================================    -->   This header provides full provenance tracking: what was archived,  where it came from, who archived it, and when.  RESOURCE INLINING   sbot inlines all resources to create truly self-contained archives:   Resource Type       Inlining Method  ------------------  ------------------------------------------------  CSS stylesheets     Fetched and inserted as style blocks  Images              Base64-encoded as data:image/* URIs  Fonts               Base64-encoded as data:font/* URIs  Other media         Base64-encoded with appropriate MIME type   Resources that fail to fetch are silently skipped -- the archive  degrades gracefully rather than failing entirely.  BUILD   Requires libcurl development headers.   Arch Linux:    sudo pacman -S curl   Debian/Ubuntu:    sudo apt install libcurl4-openssl-dev   Build:    make   Install to /usr/local/bin:    sudo make install   Clean:    make clean  CONFIGURATION   All configuration is compile-time via config.h:   Setting            Default       Description  -----------------  ------------  -----------------------------------  USER_AGENT         sbot/0.3      HTTP User-Agent string  CONNECT_TIMEOUT    30s           Connection timeout  REQUEST_TIMEOUT    60s           Total request timeout  MAX_REDIRECTS      10            Maximum HTTP redirects to follow  MAX_DEPTH          5             Default recursive crawl depth  RATE_LIMIT_MS      1000ms        Delay between requests  MAX_FILE_SIZE      50 MB         Maximum size per resource  OUTPUT_EXT         .gwtar.html   File extension for archives   Edit config.h and rebuild to change any setting. This is the suckless  way -- no runtime configuration files, no environment variables, no  hidden defaults.  ARCHITECTURE   archiver.c   Main entry, page archiving, CSS inlining, link rewriting  crawl.c      URL queue (BFS), visited set, URL normalization  fetch.c      HTTP fetching via libcurl  parse.c      HTML parsing, resource extraction, image inlining  robots.c     robots.txt fetching, parsing, rule matching  util.c       Memory wrappers, string ops, base64, MIME types  config.h     Compile-time constants   Single external dependency: libcurl. No XML parsers, no HTML5 parsers,  no JavaScript engines. The HTML parsing is deliberately simple --  regex-based extraction of src, href, and url() references. This handles  the vast majority of real-world pages and keeps the codebase small and  auditable.  PHILOSOPHY   sbot follows the suckless philosophy:   - Written in C99 with POSIX.1-2008  - Minimal dependencies (libcurl only)  - Configuration through config.h (edit and recompile)  - Small, readable codebase  - Does one thing well  LICENSE   MIT/X Consortium License.
