So it's come to this...you've met us
Since 2001, 4d2 dot org has worked to provide interested folks with free access to communication and collaboration services in a mixed Linux/BSD environment. We focus on technical transparency, user privacy and free speech, with a dash of cypherpunk and retrocomputing for good measure (ask us about building a web server on a C64 or running NetBSD on an Amiga 3000).
Hey! Free pro-privacy services! (scroll down for all the details)

A cult? We wish! In fact, we hope that by providing these free services, we will encourage you to learn more about our perfectly normal new religious order, the Reformed Tertiary Quantum Church of the Ravenous Bugblatter Beast of Traal. Please send your best drawing of a $5 U.S. banknote and a stamped envelope addressed to your childhood self, into which you have screamed a detailed account of a time when your mother deeply disappointed you, to All Computers Are Brilliant Inc., 5441 S. Macadam Ave. Suite 4243, Portland OR 97239, USA. You will receive a copy of our lavishly illustrated pamphlet "Four Hundred Twenty More Reasons to Be Deeply Ashamed About Your Body, Especially Those Parts Right There" via telepathy.
OK, not really. We're just trying to provide folks with access to technology that supports education, non-commercial experimentation, community-building and mutual aid. Sorry.

Full Details of Our Services Available with a Click (or tap, whatever, we're behind the times)
- 4d2 dot org BBS
- Doomscrolling got you down? Take a trip back in time with us. Access via web, telnet, or dialup to +1 541 442 4422. Home to a growing collection of online games and subversive text files, plus 1000s of DOS and Windows 3.x files, and message groups (EchoMail) from the inter-BBS networks FidoNet, fsxNet, HobbyNet, MicroNet, Dove-Net and AmigaNet.
- Matrix messaging server - (Quick Start Guide | Report a Problem User)
- Individual and group text chat, voice and video calling, with end-to-end encryption. Since Matrix servers interconnect, you can talk to anyone in the world, on any server. You can even bring in your chats from Facebook, Instagram, WhatsApp, LinkedIn, Signal, Slack, and Google Messages (including your SMS messages, if you use an Android phone). Find out how to get started.
- CryptPad collaboration server
- CryptPad provides end-to-end encrypted file storage, collaborative tools for note-taking, calendaring and whiteboarding, and a complete suite of office applications to create and edit rich documents, spreadsheets, slideshows, diagrams and more. Think Google Docs+Drive with a focus on privacy and security. Anyone can register for 1 GB of free encrypted storage without providing any personal information.
- Mastodon social community - (Register new account)
- Our home instance of the Mastodon federated social network, 4d2.social. Post, boost and discuss short pieces of text and media in an environment not run by a megalomaniacal jerkwad.
- Lemmy social community
- Our instance of Lemmy, a link aggregator and social community that federates with other Lemmy instances to provide a non-commercial alternative to Reddit. Browse posts from the entire Lemmyverse, or create an account to post, comment and up/down vote.
- PeerTube video streaming service
- Stream hundreds of thousands of uploaded videos from across the Fediverse, or create an account to upload your own. A federated, non-commercial alternative to YouTube.

- Vaultwarden password management server
- Works with official Bitwarden client apps and browser extensions, and provides nearly all Bitwarden premium features for free: security reports, emergency contacts, encrypted attachments and file sends, YubiKey OTP integration, and built-in TOTP authentication. Zero-knowledge encryption means we have no access to your data. For security, we recommend signing up using an official Bitwarden desktop or mobile app. Just select "self hosted" and set https://vault.4d2.org as your server URL.
- URL shortening service
- Turn long URLs into short ones like 4d2.link/fQ4D5x, or custom ones like 4d2.link/mykazoosolo. No advertising. Great for QR codes.
- Ridiculously simple file sharing service
- Upload files from anywhere and get an instant link others can use to download them. No Javascript, no complicated authentication. Works fine with your 20-year-old browser or your shell script.
- Email information and tools
- Warrant canary (what's that?) - User data disclosure report - PGP public key
- We currently update the canary every 48-72 hours.
- The proprietors' recipe book
- As in actual food, not technology.
Our users place a lot of trust in us and we want them to feel safe. We will provide 3 months' notice before discontinuing any service listed above, allowing you time to transition to another provider. We also maintain a 3-month emergency fund to allow us to provide notice and wind down operations in the event of financial trouble. That said, we've been here since 2001 and don't intend to go anywhere soon.
We may still immediately discontinue a service due to critical vulnerabilities in an abandoned product, catastrophic system failure, legal demand, natural disaster, etc.
