The world of peer-to-peer file sharing in browsers has evolved significantly over the years, with FilePizza recently launching its second version to address modern file sharing needs. However, community discussions reveal growing concerns about the fragmentation of P2P file sharing solutions and the looming threat of acquisitions by crypto companies.
The Evolution of Browser-Based P2P File Sharing
FilePizza v2 represents a significant update to the peer-to-peer file transfer service that uses WebRTC to enable direct browser-to-browser file transfers without server storage. The new version boasts improved features including a dark mode interface, mobile browser compatibility, direct transfers with faster handshakes, transfer progress monitoring, password protection, multi-file uploads, streaming downloads via Service Worker, and Redis-based server state storage. While FilePizza offers a clean, straightforward approach to file sharing with memorable word-based URLs, it exists in an increasingly crowded ecosystem of similar tools.
Popular P2P File Sharing Alternatives Mentioned
- FilePizza: Browser-based WebRTC file transfers with word-based URLs
- PairDrop: Cross-network device pairing with QR code support
- magic-wormhole: Command-line tool with code-based pairing
- WebWormhole: Browser and CLI support with code-based pairing
- croc: Command-line file transfer tool
- Wormhole.app: Browser-based file sharing (not related to magic-wormhole)
- Blip.net: Cross-platform AirDrop alternative that works over internet and LAN
FilePizza v2 Key Features
- Dark mode UI built on modern browser technologies
- Mobile browser compatibility (including Mobile Safari)

- Multi-file upload support (downloads as zip)
- Streaming downloads with Service Worker
- Redis-based server state storage
The Acquisition Threat: LimeWire's Return
A significant concern emerging from community discussions is the pattern of P2P file sharing tools being acquired by cryptocurrency companies. Several commenters expressed alarm about LimeWire – once a popular file-sharing application that was sued out of existence – being resurrected as a crypto/AI company that has been acquiring open-source file sharing projects.
I recommended snapdrop to everyone in my family and friends for local data sharing without a cable. When I discovered that it now uploads stuff to Limewire I was so annoyed that I had to admit I suggested a harmful tool for sharing private data.
Both ShareDrop and Snapdrop, previously popular open-source alternatives, have reportedly been acquired by this new incarnation of LimeWire, raising concerns about privacy and the future of independent P2P file sharing tools. This has left users searching for alternatives that remain truly peer-to-peer without compromising user data.
Technical Limitations and Security Concerns
Despite the promise of peer-to-peer connections, community members raised important technical considerations about WebRTC-based file sharing. Many users reported difficulty establishing connections, particularly when both parties are behind strict NAT configurations. While WebRTC uses STUN servers to facilitate connections, it sometimes requires TURN servers as fallbacks when direct connections fail – raising questions about true peer-to-peer privacy.
Security-minded users pointed out that even with end-to-end encryption between peers, the initial connection setup relies on signaling servers that could potentially be compromised. This creates a trust issue where users must rely on the service provider not to manipulate the JavaScript code to intercept transfers. Additionally, some users reported persistent connection problems even in seemingly ideal network conditions, suggesting that the technology still faces reliability challenges.
The Search for the Perfect File Transfer Solution
Community discussions revealed a common frustration: despite numerous attempts to solve the sending a file to someone problem (famously illustrated in XKCD comic #949), no single solution has emerged as the universal standard. Users continue to seek a tool that combines ease of use with true privacy and cross-platform compatibility.
Many commenters shared their preferred alternatives, including PairDrop, magic-wormhole, croc, Wormhole.app, WebWormhole, and various command-line tools. Each offers different tradeoffs between simplicity, security, and features. Some users expressed nostalgia for Opera's early Unite feature from around 2010, which offered browser-based P2P file transfers long before WebRTC existed.
The ideal solution described by many would combine the simplicity of Apple's AirDrop with cross-platform compatibility and true peer-to-peer security. However, as one commenter noted, the lack of a universal standard may be intentional, as companies like Apple benefit from the ecosystem lock-in that proprietary solutions like AirDrop provide.
As P2P file sharing continues to evolve, FilePizza v2 represents one more attempt to solve this persistent problem. Whether it will remain independent or eventually join the ranks of acquired services remains to be seen, but the community's vigilance around privacy and true peer-to-peer functionality suggests that demand for trustworthy file sharing solutions remains strong.
