gnoscope

Formerly mygnoscan. Same tool, same data, same URLs, renamed on 2026-09-28. Nothing moved: docs/rename.md lists every old name and where it now points.

A fast, minimal block explorer for gno.land — built around the question generic explorers answer badly: what code is deployed, what does it import, and who actually calls it?

Transactions and blocks are table stakes. The dependency and usage graph between realms is the point.

What it does

• Realm inspector — source, imports, dependents, callers, MsgRun references
• Realm screenshots — what each realm actually looks like, on its own page and in every listing
• Dependency graph — interactive D3 view of what imports what
• Usage tracking — direct calls, indirect imports, MsgRun references
• Multi-network — several chains in one instance and one database, switchable
• Analytics — activity over time, gas, storage growth, leaderboards
• Embeddable badges — /_badges/* draws a usage graph, or a one-line shield (live, 1,284 txs, 42 users, r6), for any markdown to carry: a README, a wiki, a gno realm's own Render()
• Single binary — Go backend with the frontend embedded, no Node.js

Built on the tx-indexer GraphQL API, with a local SQLite cache for the dependency analysis.

Quick start

make install
gnoscope
# http://localhost:8888

Point it at one network:

gnoscope -indexer https://indexer.onyx.testnets.gno.land/graphql/query -network onyx

…or several, with a config file:

gnoscope -config networks.json

With Docker:

docker run -p 8888:8888 ghcr.io/gnoverse/gnoscope:main
