NOSTR WORKBENCH
Protocol Toolkit

Auxiliary Tools for Nostr Creators

Decentralized protocols deserve master-class tooling. Analyze Bech32 parameters, backup lists, validate identities, find pristine relays, and run client simulations directly on the web.

Backup Contacts

Export and secure your follow roster (kind 3). Download structured list JSON formats easily to carry them across clients.

Launch Tool

Register NIP-05

Bind your cryptographic public key to a simple, human-readable DNS handle. Complete validation map setup easily.

Launch Register NIP-05 Domain

Bech32 Decoder

Decode and convert npub, nsec, nevent, and nprofile objects back into raw, human-auditable hexagonal format.

Relay Index

Check out live index of healthy, responsive relays curated by nostrwat.ch. Keep your relays list optimized and synchronized.

zpng Compression

Highly-compressed, decentralized native image asset standard. Designed to fit avatars directly inside event profiles securely.

Npub Vanity Miner

Simulate and calculate computational difficulty required to mint customized key prefixes like "npub1cat..." or "npub1cool...".

Interactive Demo

Live Playgrounds & Sandbox Consoles

Perform instant operations with our built-in offline Nostr simulators. Secure and client-side processing guaranteed.

Bech32 Live Converter

Tool Sandbox

Input any structured Nostr string starting with npub, nsec, or note to instantly trace its hex value and checksum validity.
