Runme is great. One thing I required was mobile support which I didn't see in Runme. I also thought the VS Code dependency was a bit heavy for me since I otherwise don't use VS Code.

- env vars parametrization: this is an issue I've hit myself and am looking to add a solution for it. Created an issue for it: https://github.com/ledgesh/ledge/issues/9

- CLI: Ledge does have a CLI. One gap is it can't run a code block from the CLI - another good item to add. Created as an issue: https://github.com/ledgesh/ledge/issues/10

- flags: you can add flags in the codeblock in Ledge (like confirm, norun, etc)

Thanks for the great input!
