Analyzing multi-gigabyte JSON files locally
https://github.com/reegnz/jq-zsh-plugin
I find that for big datasets choosing the right format is crucial. Using json-lines format + some shell filtering (eg. head, tail to limit the range, egrep or ripgrep for the more trivial filtering) to reduce the dataset to a couple of megabytes, then use that jq-repl of mine to iterate fast on the final jq expression.
I found that the REPL form factor works really well when you don't exactly know what you're digging for.

Angle-grinder: Slice and dice logs on the command line
See https://lnav.org for a powerful mini-ETL CLI power tool; it embeds SQLite, supports ~every format, has great UX and easily handles a few million rows at a time.

Toolong: Terminal application to view, tail, merge, and search log files
The code base seems like a good reference as a small Python project.
My fav option in this class of apps: https://lnav.org/ It lets you use journalctl with pipes as requested here: https://github.com/Textualize/toolong/issues/4

Logdy.dev – web based logs viewer UI for local development environment
For local development, I cannot recommend lnav[1] enough. Discovering this tool was a game changer in my day to day life. Adding comments, filtering in/out, prettify and analyse distribution is hard to live without now.
I don't think a browser tool would fit in my workflow. I need to pipe the output to the tool.

Ask HN: How does `lnav` run its playground which you can just SSH into?
It looks like they run an SSH server inside a Docker container defined by this Dockerfile [1]. This uses the ForceCommand directive in the sshd_config file to ensure that a specific command is run when a user connects (rather than the user connecting directly to a shell).
Depending on whether the user connects as the `playground` or `tutorial1` user they interact with a bash script that is either [2] or [3].
