- Bazil is a distributed file system designed for single-person disconnected operation. It lets you share your files across all your computers, with or without cloud services. FUSE is a programming library for writing file systems in userspace, in Go.
- Ori - a distributed P2P file system built for offline operation and empowers the user with control over synchronization operations and conflict resolution. We provide history through light weight snapshots and allow users to verify the history has not been tampered with. Through the use of replication instances can be resilient and recover damaged data from other nodes. 
- https://www.aerofs.com/ - freemium
- Infinit - allows for the creation of heterogeneous storage infrastructure by aggregating various storage resources and unifying them into a UNIX-like Infinit file system.
- lsyncd - designed to synchronize a local directory tree with low profile of expected changes to a remote mirror. Lsyncd is especially useful to sync data from a secure area to a not-so-secure area. Lsyncd watches a local directory trees event monitor interface (inotify or fsevents). It aggregates and combines events for a few seconds and then spawns one (or more) process(es) to synchronize the changes. By default this is rsync. Lsyncd is thus a light-weight live mirror solution that is comparatively easy to install not requiring new filesystems or block devices and does not hamper local filesystem performance.
- inosync daemon leverages the inotify service available in recent linux kernels to monitor and synchronize changes within directories to remote nodes.
- Syncany is an open-source cloud storage and filesharing application. It allows users to backup and share certain folders of their workstations using any kind of storage, e.g. FTP, SFTP, WebDAV, Samba, Amazon S3 or Google Storage. While the basic idea is similar to Dropbox, Syncany is open-source and additionally provides data encryption and more flexibility in terms of storage type and provider.
- Syncthing - Open Source Continuous File Synchronization. Syncthing replaces proprietary sync and cloud services with something open, trustworthy and decentralized. Your data is your data alone and you deserve to choose where it is stored, if it is shared with some third party and how it's transmitted over the Internet. This is the Syncthing project which pursues the following goals: Define a protocol for synchronization of a folder between a number of collaborating devices. This protocol should be well defined, unambiguous, easily understood, free to use, efficient, secure and language neutral. This is called the Block Exchange Protocol. Provide the reference implementation to demonstrate the usability of said protocol. This is the syncthing utility. We hope that alternative, compatible implementations of the protocol will arise. 
The discovery mechanism can take a minutes or two to kick in.
- Port 22000/TCP (or the actual listening port if you have changed the Sync Protocol Listen Address setting.)
- Port 21027/UDP (for discovery broadcasts on IPv4 and multicasts on IPv6)
Local only access;
<gui enabled="true" tls="false"> <address>127.0.0.1:8080</address> </gui>
<gui enabled="true" tls="false"> <address>0.0.0.0:8080</address> </gui>
- Unison is a file-synchronization tool for OSX, Unix, and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
gtk2 gui is a bit dodge, drops any ssh args given to it.
syncing requires a manual start.
- SparkleShare creates a special folder on your computer. You can add remotely hosted folders (or "projects") to this folder. These projects will be automatically kept in sync with both the host and all of your peers when someone adds, removes or edits a file.
- Seafile - an open source cloud storage system with features on privacy protection and teamwork. Collections of files are called libraries, and each library can be synced separately. A library can also be encrypted with a user chosen password. Seafile also allows users to create groups and easily sharing files into groups.
- git-annex allows managing files with git, without checking the file contents into git. While that may seem paradoxical, it is useful when dealing with files larger than git can currently easily handle, whether due to limitations in memory, time, or disk space. git-annex is designed for git users who love the command line. For everyone else, the git-annex assistant turns git-annex into an easy to use folder synchroniser.
- https://git-annex.branchable.com/assistant/ - auto commits and syncs
- https://www.mayrhofer.eu.org/dvcs-autosync - Automatically keep DVCS repositories in sync whenever changes happen by automatically committing and pushing/pulling.
- DirSync Pro is a small, but powerful utility for file and folder synchronization. DirSync Pro can be used to synchronize the content of one or many folders recursively. Use DirSync Pro to easily synchronize files from your desktop PC to your USB-stick (/Externa HD/PDA/Notebook, ...). Use this USB-stick (/Externa HD/PDA/Notebook, ...) to synchronize files to another desktop PC. Using DirSync Pro you can make incremental backups. In this way you'll spare lots of time because you don't have to copy all the files each time you want to update your backup; only new/modified/larger files would be copied. DirSync Pro provides some preconfigured modes (e.g. Mirror, Backup, Contribute, ?) for common synchronization and backup tasks and some custom modes in which the user could set up the synchronization behavior to meet specific wishes.
- Conduit - a synchronization application for GNOME. It allows you to synchronize your files, photos, emails, contacts, notes, calendar data and any other type of personal information and synchronize that data with another computer, an online service, or even another electronic device. Conduit manages the synchronization and conversion of data into other formats
- Csync2 is a cluster synchronization tool. It can be used to keep files on multiple hosts in a cluster in sync. Csync2 can handle complex setups with much more than just 2 hosts, handle file deletions and can detect conflicts. It is expedient for HA-clusters, HPC-clusters, COWs and server farms.

- lipsync! - an open source, commandline service that securely syncronizes your data. Powered by lsyncd, unison, ssh and fak3r. Think of it as a lightweight commandline version of Dr0pb0x that gives control back to you; the user and owner of the data.
- Pydio is an open source software that turns instantly any server (on premise, NAS, cloud IaaS or PaaS) into a file sharing platform for your company. It is an alternative to SaaS Boxes and Drives, with more control, safety and privacy, and favorable TCOs.
- bitpocket is a small but smart script that does 2-way directory synchronization. It uses rsync to do efficient data transfer and tracks local file creation/removal to avoid known rsync problem when doing 2-way syncing with deletion. bitpocket can use any server which you have ssh access to for its central storage. If you have gigabytes of free disk space on your hosting server you can finally make use of it.

- P-Grid is a truly decentralized structured P2P system which does not require central coordination or knowledge. It is based purely on randomized algorithms and local interactions and targeted at environments with low online probabilities of peers. P-Grid differs from other approaches such as Chord, CAN, Pastry, etc. in terms of practical applicability (especially in respect to dynamic network environments), algorithmic foundations (randomized algorithms with probabilistic guarantees), robustness, and flexibility.
- TomP2P is an advanced DHT, which stores multiple values for a key. Each peer has a table (either disk-based or memory-based) to store its values. A single value can be queried / updated with a secondary key. The underlying communication framework uses Java NIO to handle many concurrent connections.

- https://en.wikipedia.org/wiki/WebRTC - an API definition drafted by the World Wide Web Consortium (W3C) that supports browser-to-browser applications for voice calling, video chat, and P2P file sharing without the need of either internal or external plugins.
Two peers first need to find one another. This signalling step is purposefully omitted from the WebRTC specification, since the WebRTC protocol is not specific to browsers and can be used by any number of different devices in different circumstances. Sometimes this is hindered by network topology realities, e.g. non-permissive firewalls or NAT routers. In this case it is physically impossible for the two peers to communicate in a P2P manner and a third party relay is required; this is included in the WebRTC specification in the form of a TURN server. 
- simpleWebRTC - You can build cool stuff with WebRTC in five minutes. Want to see what this library can do? Check out the videochat, audiochat (works in Microsoft Edge, too!) and file transfer demos.
- https://github.com/sarandogou/webrtc-everywhere - an open source project (with business-friendly license) to add support for WebRTC features to Safari (Windows and MAC OSX) and Internet Explorer (Windows).
- webrtc2sip is a smart and powerful gateway using RTCWeb and SIP to turn your browser into a phone with audio, video and SMS capabilities. The gateway allows your web browser to make and receive calls from/to any SIP-legacy network or PSTN. As an example, you will be able to make a call from your preferred web browser to a SIP-legacy softphone (e.g. xlite) or mobile/fixed phone. The gateway contains four modules: SIP Proxy | RTCWeb Breaker | Media Coder | Click-to-Call.
- Janus - a WebRTC Gateway developed by Meetecho conceived to be a general purpose one. As such, it doesn't provide any functionality per se other than implementing the means to set up a WebRTC media communication with a browser, exchanging JSON messages with it, and relaying RTP/RTCP and messages between browsers and the server-side application logic they're attached to. Any specific feature/application is provided by server side plugins, that browsers can then contact via the gateway to take advantage of the functionality they provide. Example of such plugins can be implementations of applications like echo tests, conference bridges, media recorders, SIP gateways and the like.
- Kurento - a WebRTC media server and a set of client APIs making simple the development of advanced video applications for WWW and smartphone platforms. Kurento Media Server features include group communications, transcoding, recording, mixing, broadcasting and routing of audiovisual flows. As a differential feature, Kurento Media Server also provides advanced media processing capabilities involving computer vision, video indexing, augmented reality and speech analysis. Kurento modular architecture makes simple the integration of third party media processing algorithms (i.e. speech recognition, sentiment analysis, face recognition, etc.), which can be transparently used by application developers as the rest of Kurento built-in features.

Fully distributed persistent chatrooms with no single points of control or failure. WebRTC signalling transport for interoperable VoIP and video calling. Exchanging and persisting data between devices and services.
Encrypted / anon
- WASTE is an anonymous, secure, and encryped collaboration tool which allows users to both share ideas through the chat interface and share data through the download system.
The suggested size for a WASTE network (referred to as a "mesh" by users) is 10-50 nodes, though it has been suggested that the size of the network is less critical than the ratio of nodes willing to route traffic to those that are not.
- Freenet - Share files, chat on forums, browse and publish, anonymously and without fear of blocking or censorship! While users can insert data into the network, there is no way to delete data. Due to the anonymity, no node knows who is the 'owner' of a piece of data. The only way data can be removed is if users don't request the data.
- RetroShare is a Open Source cross-platform, Friend-2-Friend and secure decentralised communication platform. It lets you to securely chat and share files with your friends and family, using a web-of-trust to authenticate peers and OpenSSL to encrypt all communication. RetroShare provides filesharing, chat, messages, forums and channels
- MUTE File Sharing is a peer-to-peer network that provides easy search-and-download functionality while also protecting your privacy.
- OneSwarm is a P2P file sharing service that protects your privacy. It's fast, BitTorrent-compatible, and free!
- OFF is a highly connected peer-to-peer distributed file system. The unique feature of this system is that it stores all of its internal data as meaningless multi-use data blocks. In other words there is not a one to one mapping between a stored block and its use in a accessed file. Each stored block is simultaneously used to access many different files. Individually however, each block is nothing but arbitrary digital white noise.
Free Haven Project
- Free Haven Project aims to deploy a system for distributed, anonymous, persistent data storage which is robust against attempts by powerful adversaries to find and destroy any stored data. This model of decentralized system has been classified as peer-to-peer by recent popular media.
- Tahoe-LAFS is a Free and Open cloud storage system. It distributes your data across multiple servers. Even if some of the servers fail or are taken over by an attacker, the entire filesystem continues to function correctly, preserving your privacy and security.
