Motivation

There are two driving factors behind this project:

• In the age of information, all data is ephemeral. Social media platforms frequently delete content, and cloud storage services can become inaccessible and unreliable. Being able to archive important data is very important for preserving personal memories and digital history.
• I will be creating a small encyclopedia for my future family and kids. Therefore, I want to make sure that all the information I gather is preserved and accessible for future reference.

This project aims to provide a reliable solution for archiving important data from various sources, ensuring that users can preserve their digital assets for the long term.

Archive Inputs

archivr archive <path> currently accepts three kinds of inputs:

• Local files via file://...
• Direct platform URLs
• Platform shorthand inputs such as tweet:..., yt:..., or instagram:...

Running Archivr

Archivr currently ships as two binaries:

• archivr
  • The CLI for creating and writing to one archive.
  • Use this for init and archive.
• archivr-server
  • The web server for reading one or more existing archives through the browser UI.
  • Use this after archives already exist.

With Nix, run the CLI with:

nix run .#archivr -- init ./my-archive --name "My Archive"
nix run .#archivr -- archive file:///absolute/path/to/file.pdf

Run the web server with:

nix run .#archivr-server -- ./archivr-server.toml

The server expects a TOML registry file. If no path is passed, it reads ./archivr-server.toml.

Example:

[[archives]]
id = "personal"
label = "Personal"
archive_path = "/absolute/path/to/my-archive/.archivr"

Then open:

http://127.0.0.1:8080

When installed through Nix, archivr-server is wrapped so it can find the static web UI assets automatically. The wrapper sets ARCHIVR_STATIC_DIR to the installed static asset directory. Running from source with cargo run -p archivr-server falls back to crates/archivr-server/static.

Security and Deployment

archivr-server is a local-only tool by default. It binds to 127.0.0.1:8080 and has no authentication or access control. Do not expose it to a public network or a shared LAN without understanding the risks.

Changing the bind address

You can set the bind address in your TOML config:

# Optional. Default: 127.0.0.1:8080
# Only change this if you know what you are doing — the server has no authentication.
bind = "127.0.0.1:9090"

Or override it with the ARCHIVR_BIND environment variable:

ARCHIVR_BIND=127.0.0.1:9090 nix run .#archivr-server -- ./archivr-server.toml

If the server is started with a non-loopback address (e.g. 0.0.0.0), it prints a warning to stderr:

warn: archivr-server is bound to 0.0.0.0:8080 — this server has no authentication. Only expose it on a trusted network.

When will auth be added?

Auth and session handling will be designed when remote or public hosting becomes a real requirement. Until then, keep the server on loopback. See crates/archivr-server/src/routes.rs for the route classification that will guide where middleware is applied.

Supported Platforms

• Local files: file:///absolute/path/to/file.ext
• YouTube media: standard video/short URLs, plus shorthand video inputs
• X/Twitter media from Tweets: normal Tweet URLs or the tweet:media:ID shorthand
• X/Twitter Tweet content scrape: Tweet and Thread shorthands. (These are saved as JSON files in raw_tweets/)
• Instagram, Facebook, TikTok, Reddit, Snapchat: direct URLs or platform-prefixed shorthand passed through to yt-dlp

Hosting on NixOS

The flake exposes a nixosModules.default output. Add it to your system flake and enable the service:

# flake.nix (your system flake)
{
  inputs.archivr.url = "github:thegeneralist/archivr";

  outputs = { nixpkgs, archivr, ... }: {
    nixosConfigurations.myhost = nixpkgs.lib.nixosSystem {
      modules = [
        archivr.nixosModules.default
        {
          services.archivr-server = {
            enable = true;
            # listenAddress defaults to "127.0.0.1" (loopback only)
            # port defaults to 8080
            archives = [
              { id = "personal"; label = "Personal"; path = "/srv/archivr/personal/.archivr"; }
              { id = "work";     label = "Work";     path = "/srv/archivr/work/.archivr"; }
            ];
          };
        }
      ];
    };
  };
}

The module:

• Creates an archivr system user and group.
• Generates the TOML config from your options and stores the auth database under /var/lib/archivr-server/ (persists across upgrades).
• Runs under a hardened systemd unit (ProtectSystem = strict, NoNewPrivileges, PrivateTmp, etc.). Archive directories are whitelisted for read-write access.
• Restarts automatically on failure.

openFirewall — set to true to open the TCP port derived from bind. Only needed when binding to a non-loopback address:

services.archivr-server = {
  listenAddress = "0.0.0.0";
  port = 8080;            # explicit, though 8080 is the default
  openFirewall = true;
};

Archive directories must be readable and writable by the archivr user. Initialise them with archivr init first, then chown -R archivr:archivr /srv/archivr.

Hosting with Docker

A Dockerfile and docker-compose.yml are provided for self-hosting without Nix.

Quickstart

1. Copy the example config and edit it:

   mkdir config
   cp docker/config.example.toml config/archivr-server.toml
   # edit config/archivr-server.toml — set archive id, label, and archive_path
   

2. Initialize each archive on the persistent data volume before the first start. The image includes the archivr CLI for this purpose:

   docker compose run --rm archivr archivr init /data/archives/main /data/archives/main/.archivr/store --name "Main Archive"
   

   This creates /data/archives/main/.archivr/ with the metadata the server requires. A bare mkdir is not enough — the server reads name and store_path files that only archivr init writes.

3. Start the server:

   docker compose up -d
   

   Then open http://localhost:8080.

Volumes

Mount	Purpose
./config (read-only)	Directory containing archivr-server.toml
archivr-data named volume	Auth database (/data/archivr-auth.sqlite) and archive directories

Important: auth_db_path must be set explicitly in archivr-server.toml to a path on the writable data volume (e.g. /data/archivr-auth.sqlite). If left unset, the server defaults to writing the auth database next to the config file — which is on the read-only /config mount and will fail. The example config sets this correctly.

Twitter/X archiving

Supply a cookies file inside the config volume and set ARCHIVR_TWITTER_CREDENTIALS_FILE in docker-compose.yml:

environment:
  ARCHIVR_TWITTER_CREDENTIALS_FILE: /config/twitter-cookies.txt

Building the image locally

docker build -t archivr-server .

The image compiles the Rust binary in a separate build stage so only the runtime dependencies (Chromium, Node.js, Python) land in the final layer.

Supported Shorthand Inputs

• YouTube video/short media:
  • yt:video/ID
  • youtube:video/ID
  • yt:short/ID
  • yt:shorts/ID
  • youtube:shorts/ID
• X/Twitter tweet JSON content:
  • tweet:ID
  • x:tweet:ID
  • x:x:ID
  • twitter:x:ID
  • twitter:tweet:ID
• X/Twitter media/video download:
  • tweet:media:ID
• X/Twitter thread JSON content:
  • x:thread:ID
  • twitter:thread:ID
• Other platform shorthands:
  • instagram:ID
  • facebook:ID
  • tiktok:ID
  • reddit:ID
  • snapchat:ID

Environment Variables

• ARCHIVR_BIND
  • Optional.
  • Overrides the bind address from the TOML config. Useful in Docker where you need 0.0.0.0:8080 without editing the config file. Default: 127.0.0.1:8080.
• ARCHIVR_STATIC_DIR
  • Optional.
  • Path to the directory of pre-built frontend assets served by the web UI. Set automatically by the Nix wrapper and the Docker image. When running from source with cargo run, falls back to crates/archivr-server/static.
• ARCHIVR_YT_DLP
  • Optional.
  • Overrides the yt-dlp binary used for YouTube, X media posts, Instagram, Facebook, TikTok, Reddit, and Snapchat downloads.
• ARCHIVR_SINGLE_FILE
  • Optional.
  • Overrides the single-file binary used for web page archiving. Set automatically by the Nix wrapper and the Docker image.
• ARCHIVR_CHROME
  • Optional.
  • Overrides the Chromium/Chrome executable passed to single-file via --browser-executable-path. Set automatically by the Nix wrapper and the Docker image. Default: chromium.
• ARCHIVR_CHROME_ARGS
  • Optional.
  • Space-separated extra flags appended to Chromium's --browser-args. The Docker image sets this to --no-sandbox because Chromium refuses to run as root without it. Leave unset when running natively (Nix, Linux desktop). A --window-size=1920,1080 is always passed to provide a realistic desktop viewport (so responsive @media rules and styles are evaluated and preserved correctly). Supply your own --window-size=... here to override.
• ARCHIVR_TWITTER_CREDENTIALS_FILE
  • Required for tweet/thread scraping inputs such as tweet:ID and x:thread:ID.
  • Must point to a cookies file for the vendored scraper.
• ARCHIVR_TWEET_SCRAPER
  • Optional.
  • Overrides the tweet scraper script path. Default: vendor/twitter/scrape_user_tweet_contents.py.
• ARCHIVR_TWEET_PYTHON
  • Optional.
  • Overrides the Python executable used to run the tweet scraper. Default: python3.

Current Limitations

• Arbitrary http:// or https:// URLs that return HTML are archived as self-contained single-file HTML snapshots via single-file-cli (requires Chromium). Plain file URLs (PDFs, images, zips, etc.) are downloaded directly. Requires single-file and a Chromium binary on PATH, or the ARCHIVR_SINGLE_FILE / ARCHIVR_CHROME env vars set.
• Local files currently need to be passed as file://... paths.
