A small, fast, read-only pager for JSON Lines logs, in the terminal or a local browser tab. One native executable, no runtime.
Linux and macOS:
curl -fsSL https://jlog.logging.work/install.sh | sh
The script downloads the archive for your system, checks its SHA-256 against
SHA256SUMS and installs jlog into ~/.local/bin
(override with JLOG_INSTALL_DIR). Or download an archive yourself:
