The Cipr (Cosmic Index of Public Resources) is a decentralized, distributed, and censorship-resistant web index where domain owners control their own entries.
No crawler decides if you are worth indexing. No curator approves your submission. No central authority can delist you. If you own a domain, you publish a small daemon, add a DNS TXT record, and your site is in the index, worldwide, in minutes. Updating your entry or leaving for good is also quick and easy.
The Cipr is not a search engine in the traditional sense. It is a shared, peer-to-peer directory where every participant holds a full copy and keeps it in sync through viral propagation. Search results are ranked by standardized, publicly auditable factors (BM25 over owner-declared metadata), not by opaque algorithms or ad revenue.
Censoring a Cipr entry requires DNS-level intervention - the same infrastructure-level action needed to take down a domain itself. There is no central server to shut down, no API key to revoke, no terms of service to violate.
It is best suited for the small web: personal blogs, homelab services, independent projects, community resources - the kinds of sites that mainstream search engines are increasingly burying or ignoring entirely.
Ciprnode zero is the first and reference implementation of the Cipr protocol. It is built entirely on Deno with zero runtime npm dependencies. The local index is a SQLite database with an external-content FTS5 virtual table and BM25 ranking. The API is a strict Semantic RESTful implementation with full HATEOAS compliance via HAL+JSON, including real-world use of the QUERY HTTP method (draft-ietf-httpbis-safe-method-with-body).
A built-in web interface (the ciprface) provides search with filters for language, geographic proximity, offensiveness level, and timestamp. Verification uses DNS TXT triple validation (3 random DoH resolvers via custom TLS connections) and viral P2P propagation. No central server, no blockchain, no token. MIT licensed, self-hostable, compiles to a standalone binary for Linux, Windows, and macOS.
