Awesome Offline Knowledge [](https://awesome.re)

September 5, 2026 · View on GitHub

A curated list of content, tools, and infrastructure for keeping knowledge accessible without the internet — for disasters, shutdowns, remote regions, classrooms, and the long term.

Scope. This list is about offline access to knowledge: openly licensed content you can store locally, tools to read, serve, and capture it, and the ways it travels without a network. It completes a triangle with two sibling lists, both under Other Related Lists below: awesome-decentralized-web (who controls the infrastructure) and awesome-resilient-communication (how people communicate when infrastructure fails).

Out of scope:

  • Pirated or unlicensed content — everything listed is openly licensed, public domain, or a tool.
  • Cryptocurrency- and token-dependent projects.
  • AI tools and agent frameworks.
  • General self-hosting software without an offline-first purpose.

Please read CONTRIBUTING.md before submitting a project.

How to read this list. Three different things get called "offline knowledge", and you usually need all three:

  • Content — the knowledge itself, in bulk and openly licensed. (Wikimedia dumps, Project Gutenberg, OpenStreetMap)
  • Tools — readers, servers, and capture software that make content usable off the network. (Kiwix, Calibre, ArchiveBox)
  • Transport — how content moves without connectivity: hotspots, removable media, sneakernets. (Internet-in-a-Box, NNCP)

Entries marked Dormant still work but their source repository has had no activity for over 2 years — the tag states the measured date. Dead projects live in the Graveyard section at the bottom.

Contents

Content Collections

Readers and Reference Tools

Software for using stored knowledge on your own device.

  • Aard2 - Android dictionary and Wikipedia reader for slob-format offline archives.
  • Calibre - The standard tool for e-book library management, format conversion, and reading.
  • DevDocs - Combined API documentation browser for hundreds of programming tools, installable for fully offline use.
  • GoldenDict-ng - Feature-rich dictionary application supporting StarDict, Babylon, and many other offline dictionary formats.
  • Kiwix - Reader and server for ZIM archives on desktop, mobile, and Raspberry Pi — the standard way to use Wikipedia offline.
  • KOReader - Document and e-book reader for e-ink devices, phones, and desktops.
  • Zeal - Offline documentation browser for developers, using Dash-format docsets.

Offline Servers and Learning Platforms

A box that serves knowledge to everyone nearby.

  • Internet-in-a-Box - Turns a Raspberry Pi into a local knowledge hotspot serving Wikipedia, maps, books, and lessons to nearby devices.
  • Kolibri - Offline-first learning platform that syncs curricula between devices without internet, by Learning Equality.
  • RACHEL - Preloaded offline education server used in schools and community centers without connectivity, by World Possible.

Maps and Navigation

  • CoMaps - Community-governed offline maps and navigation app built on OpenStreetMap data, forked from Organic Maps.
  • OpenStreetMap - The openly licensed map of the world; its data extracts power every offline maps app on this list.
  • Organic Maps - Offline maps and navigation app built on OpenStreetMap data, with detailed hiking and cycling coverage.
  • OsmAnd - Highly configurable offline maps, navigation, and map-editing app built on OpenStreetMap data.
  • Protomaps - Serves an entire planet of map tiles from one static file (PMTiles), making self-hosted offline maps practical.

Capture and Archiving Tools

Make your own offline copies while the network is still up.

  • ArchiveBox - Self-hosted web archive that snapshots the pages you feed it into several durable formats.
  • HTTrack - Long-standing website copier that mirrors entire sites for offline browsing.
  • Monolith - Bundles a complete web page, assets included, into a single self-contained HTML file.
  • SingleFile - Browser extension that saves any page as one faithful, self-contained HTML file.
  • Zimit - Crawls any website into a ZIM archive readable by Kiwix.

Sneakernets and Offline Transfer

Knowledge that travels by hand.

  • apt-offline - Updates and installs Debian and Ubuntu packages on machines that never touch the network.
  • NNCP - Encrypted store-and-forward file and mail exchange over removable media, sneakernets, and intermittent links.

Case Studies

  • El Paquete Semanal - Cuba's weekly terabyte of media and software, distributed nationwide by hand on hard drives — arguably the world's largest sneakernet.

Guides and Communities

  • ArchiveTeam - Volunteer collective racing to save at-risk websites; its wiki documents formats, targets, and rescue tooling.
  • digipres.org - Community-maintained index of digital-preservation tools, formats, and practice.

Graveyard

Projects that shaped offline knowledge access but are no longer maintained. Kept for the historical record.

  • LibraryBox - Portable offline file-sharing and library server, forked from PirateBox for libraries and classrooms. Discontinued (repository inactive since 2017).
  • XOWA - Standalone offline Wikipedia reader with its own wiki database engine. Discontinued (repository inactive since 2022).
