A light Bitcoin block explorer without address indexing, using only a bitcoin core instance.
Runs live on mainnet, testnet and signet @ http://fbbe.info
Locally can run on regtest.
Supposing to have rust installed and a synced bitcoin core on mainnet with txindex=1 and rest=1 do:
git clone https://github.com/RCasatta/fbbe
cd fbbe
cargo run --release
A flake is provided to build the fbbe binary.
Whenever Cargo.toml or Cargo.lock are updated the cargo2nix tool must be launched to keep Cargo.nix in sync. See https://github.com/cargo2nix/cargo2nix
nix run github:cargo2nix/cargo2nix # needs nix-command and flakes experimental feature enabled
After changing custom.css use a minifier:

To allow running the explorer on low-resource devices the memory usage must be kept low.
Better results with debug symbols even in release mode, if not already specified in Cargo.toml
use env var CARGO_PROFILE_RELEASE_DEBUG=true.
heaptrack works by tracking memory management syscall, after installing the tool use:
cargo build --release
timeout 10m heaptrack ./target/release/fbbe # in this example the tracker runs for 10 minutes
heaptrack_gui heaptrack.fbbe.105581.zst # file created by the previous command
