💬 We offer consulting services to set up, secure, and maintain ArchiveBox on your preferred hosting environment.
We use this revenue (from corporate clients who can afford to pay) to support open source development and keep ArchiveBox free.

ArchiveBox Use-Cases


Archiving Public Content Only ⭐️ [Default, recommended for most people]

This is the default (lax) mode, intended for archiving public (non-secret) URLs without authenticating the headless browser. This is the mode used if you're archiving news articles, audio, video, etc. browser bookmarks to a folder published on your webserver. This allows you to access and link to content on http://your.archive.com/archive... after the originals go down.

The default mode should not be used for archiving entire browser history or authenticated private content like Google Docs, paywalled content, invite-only subreddits, private photo share urls, etc.

# (these are the defaults)
archivebox config --set SAVE_ARCHIVE_DOT_ORG=True
archivebox config --set CHROME_USER_DATA_DIR=None
archivebox config --set COOKIES_FILE=None

Archiving Content Behind Log-Ins 🚨 [Advanced users only]

ArchiveBox is able to archive content that requires authentication or cookies, but it comes with some caveats. Create dedicated logins for archiving to access paywalled content, private forums, LAN-only content, etc. then share them with ArchiveBox via Chrome profile + cookies.txt file.

archivebox config --set SAVE_ARCHIVE_DOT_ORG=False
archivebox config --set CHROME_USER_DATA_DIR=/path/to/chrome/profile
archivebox config --set COOKIES_FILE=/path/to/cookies.txt

To get started, set CHROME_USER_DATA_DIR and COOKIES_FILE to point to a Chrome user folder that has your sessions and a wget cookies.txt file respectively.

If you're importing private links or authenticated content, you probably don't want to share your archive folder publicly on a webserver, so don't follow the Publishing Your Archive instructions unless you are only serving it on a trusted LAN or have some sort of authentication in front of it. Make sure to point ArchiveBox to an output folder with conservative permissions, as it may contain archived content with secret session tokens or pieces of your user data. You may also wish to encrypt the archive using an encrypted disk image or filesystem like ZFS as it will contain all requests and response data, including session keys, user data, usernames, etc.

⚠️ Things to watch out for: ⚠️

Publishing

Caution

Re-hosting untrusted archived content on a domain can potentially compromise all apps on that domain!
(including other subdomains)

Make sure you thoroughly understand the dangers of hosting untrusted HTML/JS/CSS that may be captured during archiving, and how viewing it can enable CSRF attacks across all apps on the same domain. If a logged-in user happens to visit an archived page with malicious Javascript embedded, it would allow the JS to hijack any cookies on the domain and pretend to be them, potentially exfiltrating or modifying other Snapshots/data on your server.

(This is why we don't support serving ArchiveBox from a subdirectory like myapps.example.com/archivebox/, it's too dangerous to share domains)

The industry standard approach is to use a separate domain for untrusted content, for example Github uses githubusercontent.com and Google uses googleusercontent.com for all user-uploaded files. If hosting ArchiveBox publicly, do the same and keep it on an isolated domain in order to mitigate potential damage of leaked cookies, CORS, and CSRF attacks.

To protect the Admin dashboard, it's also recommended to serve all content under /archive/ on a separate domain from /admin/. We do this on our servers using a simple redirect rule in nginx/cloudflare like so:

Published archives automatically include a robots.txt Dissallow: / to block search engines from indexing them. You may still wish to publish your contact info in the index footer though using FOOTER_INFO so that you can respond to any DMCA and copyright takedown notices if you accidentally rehost copyrighted content.

⚠️ Make sure to read all the warnings above about the dangers of exposing Chrome profile data, cookies, secret tokens in URLs, and the risks of viewing archived JS on a shared origin before publishing your archive.

Do not run as root

Warning

Did you run a command in Docker with exec instead of run by accident and end up here?
Make sure you use docker run instead of docker exec to run ArchiveBox commands.

For example:
✅ docker compose run archivebox manage createsuperuser
✅ docker run -it -v $PWD:/data archivebox/archivebox manage createsuperuser
(docker run automatically uses the correct archivebox user & file permissions enforced via ./bin/docker_entrypoint.sh)

instead of:
❌ docker compose exec archivebox manage createsuperuser
❌ docker exec -it archivebox manage createsuperuser
(docker exec will skip the entrypoint and attempt to run everything as root and fail)

If you must use exec for some reason (e.g. if you only have access to a live container shell), you can run su archivebox within the shell, or add the arg --user=archivebox after exec.

Do not run ArchiveBox as root for a number of reasons:

  • Chrome will execute as root and fail immediately because Chrome sandboxing is pointless when the data directory is opened as root (do not set CHROME_SANDBOX=False just to bypass that error!)
  • All dependencies will be run as root, if any of them have a vulnerability that's exploited by sites you're archiving you're opening yourself up to full system compromise
  • ArchiveBox does lots of HTML parsing, filesystem access, and shell command execution. A bug in any one of those subsystems could potentially lead to deleted/damaged data on your hard drive, or full system compromise unless restricted to a user that only has permissions to access the directories needed
  • Do you really trust a project created by a Github user called @pirate 😉? Why give a random program off the internet root access to your entire system? (I don't have malicious intent, I'm just saying in principle you should not be running random Github projects as root)

Instead, you should run ArchiveBox under a separate user account with less privileged access:

useradd -r -g archivebox -G audio,video archivebox  # the audio & video groups are used by chrome
mkdir -p /home/archivebox/data
chown -R archivebox:archivebox /home/archivebox
...
sudo -u archivebox archivebox add ...

If you absolutely must run it as root for some reason, a footgun is provided: you can set ALLOW_ROOT=True via environment variable or in your ArchiveBox.conf file. This footgun option was removed (I'm sorry, the support burden of helping people who messed up their systems by running everything as root was too high).



Output Folder

Database

The ArchiveBox database is an unencrypted, uncompressed SQLite3 index.sqlite3 file on disk, and such does not require an authenticated admin SQL login to access (like PostgreSQL/MySQL would). Make sure to protect your database file adequately as anyone who can read it can read your entire collection contents. Passwords for the admin users are stored as salted and PBKDF2 hashed strings in the auth_user table.

Filesystem

How much are you planning to archive? Only a few bookmarked articles, or thousands of pages of browsing history a day? If it's only 1-50 pages a day, you can probably just stick it in a normal folder on your hard drive, but if you want to go over 100 pages a day, you will likely want to put your archive on a compressed/deduplicated/encrypted disk image or filesystem like ZFS. Other distributed/networked/checksummed filesystems that have also been reported to work (but are not technically officially supported) include SMB, NFS, Ceph, Unraid, and BTRFS. Make sure the filesystem you're using supports FSYNC. Some filesystems are unable to store more than a certain number of directory entries, and your total number of snapshots in ./archive may be capped as a result. Some other filesystems begin to have performance degradations but continue to function when the directory entry count gets too high. Generally this isn't an issue unless you have more than ~20,000 Snapshot folders in ./archive.

Purging entries

Unless --yes --delete is passed to archivebox remove, Snapshots removed from the index remain in the filesystem and their ./archive/<timestamp> folders need to be deleted manually to be fully removed. Imported URLs are also logged separately in ./sources, ./logs, and the Sonic full-text index ./sonic and should be removed manually as well to clear all traces of a URL added by accident. You can search for a URL on the filesystem you're trying to remove using grep -a -r "https://example.com/url/to/search/for".

Permissions

Consider what permissioning to apply to your archive folder carefully. Limit access to the fewest possible users by checking folder ownership and setting OUTPUT_PERMISSIONS accordingly. Generally the index.sqlite3 file, archive/ folder, and ArchiveBox.conf file must all be owned and writable by the archivebox user or a dedicated non-root user.

PUID & PGID can be set when running with Docker to control what user and group ArchiveBox expects to own the data directory within the container.
