Is ZeroNet still actively developed in 2026?

ZeroNet development has been slow since the original developer shifted focus. The codebase is maintained by community forks. The P2P network continues to operate. For operators building critical infrastructure, Tor's more active development and larger developer community provides better long-term support. ZeroNet is suitable for existing use cases but building new applications requiring active framework development may be better served by other platforms.

Can I host a ZeroNet site and Tor .onion site simultaneously?

Yes. You can publish content on both ZeroNet (for persistence without server) and as a Tor .onion site (for real-time interaction and better anonymity). Maintain the same content on both platforms and direct users to each based on their access requirements. This dual-publishing strategy provides both ZeroNet's censorship resistance and Tor's anonymity.

Does ZeroNet require constant internet connectivity for sites to be accessible?

ZeroNet sites are accessible to you locally even when offline (you have a local copy). For other users to access the site, at least one peer with the site files must be online. If the publisher has not been online and no other peer has the files, the site may be temporarily inaccessible. Sites with many visitors (and therefore many seeders) are more reliably accessible than obscure sites with few visitors.

What is the privacy risk of using ZeroNet without Tor?

Without Tor, all peers you connect to in the ZeroNet swarm can see your IP address. This includes the site operator (who can see which IPs are seeding their content), other visitors (who may log IP addresses), and anyone monitoring the P2P swarm. For users in authoritarian countries accessing political content on ZeroNet, IP exposure is a serious risk. Always use ZeroNet with Tor if accessing content that could create risk if your IP is known.

Can ZeroNet content be modified or deleted by anyone other than the site owner?

No. ZeroNet site content is cryptographically signed by the site owner's Bitcoin private key. Other users who seed the site cannot modify the content - they serve only signed copies. Only the private key holder can publish content updates. If the private key is lost, no one can update the site (it becomes permanently frozen at its last published state). This immutability is both a feature (censorship resistance) and a limitation (mistakes cannot be corrected without the private key).

Tor vs ZeroNet: Anonymous P2P Web Comparison

ZeroNet is a decentralized web platform that uses Bitcoin cryptography and BitTorrent-like P2P distribution to host websites that cannot be taken down or censored. Unlike Tor hidden services (which require an online server), ZeroNet sites are distributed across all users who have visited them - the site continues to be accessible as long as at least one peer has a copy. This fundamental architectural difference creates different resilience, anonymity, and use case profiles compared to Tor. Understanding when ZeroNet's censorship resistance outperforms Tor's anonymity model helps operators and users choose the appropriate tool.

ZeroNet Architecture: No Server Required

ZeroNet sites are hosted by visitors: when you visit a ZeroNet site, you download a copy of the site and automatically become a seeder. Other users can download the site from you. Site owners sign content updates with their Bitcoin private key - only the site owner can publish updates, but anyone can host copies. This creates censorship resistance that differs fundamentally from Tor: a Tor hidden service requires an online server. If the server is seized or shut down, the .onion becomes unreachable. A ZeroNet site requires no server - as long as one person has the site files and runs ZeroNet, the site is accessible. The trade-off: ZeroNet users' IP addresses are visible to each other (as in any P2P network) unless they use Tor with ZeroNet.

Anonymity: Tor Wins Decisively

Tor provides strong IP anonymity: visitors to .onion sites and site operators have their IP addresses hidden. ZeroNet without Tor: all peers in the ZeroNet network can see each other's IP addresses (P2P swarm behavior). Your IP address is visible to other ZeroNet users when you access sites or seed content. ZeroNet with Tor: configure ZeroNet to route through Tor (ZeroNet supports this configuration) - your IP is hidden from other peers but Tor's anonymity set is small for this use case. For use cases where IP anonymity is critical, Tor hidden services provide better protection than ZeroNet. For use cases where content censorship resistance is the primary concern (published content that must persist despite takedowns), ZeroNet's P2P distribution model provides stronger content availability guarantees.

Content Persistence: ZeroNet Wins for Published Content

ZeroNet's distributed hosting model provides content persistence that Tor cannot match. A Tor .onion site requires: an online server, the server's IP not being known to adversaries, and continuous operation. If any of these fail, the content becomes inaccessible. ZeroNet content persists as long as any peer has a copy. Once published on ZeroNet, content cannot be taken down by seizing the publisher's server. This is particularly valuable for: news archives that must persist despite publisher shutdown, documentation of human rights abuses that must survive government pressure on publishers, and creative works that the creator wants to survive without maintaining server infrastructure. For content that must persist long-term without continuous server maintenance, ZeroNet's model is more resilient than Tor .onion hosting.

Use Case Comparison

Use Tor (.onion hidden service) when: real-time two-way communication (messaging, comment systems, live forms), applications requiring server-side processing (login, database queries, payment processing), high-traffic services with many concurrent connections, and strong IP anonymity for both operator and visitors. Use ZeroNet when: publishing static content that must persist without a server, creating censorship-resistant archives, building communities where content availability after publisher shutdown matters, and scenarios where you want to avoid paying for continuous server hosting. Use both together when: you need Tor's anonymity while participating in ZeroNet's P2P network (configure ZeroNet to use Tor as its transport).

Dynamic Content Limitations in ZeroNet

ZeroNet sites are fundamentally static: they cannot run server-side code, query databases in real-time, or process user input server-side. Dynamic features in ZeroNet are implemented through optional databases stored locally by each user (using ZeroNet's built-in SQLite storage) and JavaScript running client-side. ZeroNet's dynamic features include: comments (stored in each user's local optional database, synced P2P), simple user profiles, and voting/rating systems. For applications requiring real-time data (live auction prices, stock data, collaborative editing), ZeroNet's P2P synchronization latency makes it unsuitable. Tor .onion services support full server-side dynamic content - the same web application stack as any web server.
