Preview Markdown exactly the way GitHub renders it, without pushing commits just to check how your README looks. It watches files live as you edit, handles Mermaid, KaTeX, and GitHub alerts, runs as a single zero-install binary - and there's a web playground to try it first.
Hi PH!
I built GitLiMP for a problem I encounter with Markdown previewers. Unlike other Markdown previewers, including extensions where it has their own Live previews, which some do not render it pretty well, GitLiMP is exclusively made only for GitHub-style rendering... nothing else. The goal is to try to mimic the same way how GitHub renders Markdown for nearly every trick without having to commit all the time just for the README preview.
Along with that, we also added Mermaid + KaTeX support to visualize how GitHub uses to render flowcharts and LaTeX formulas, and adding GitHub alerts support to the mix.
This project is built using Go + Wails, aiming to keep an optimal binary size and performance to help keep it lightweight. You can also try the Playground that I've made which looks the same as GitLiMP but for testing.
All in all, its completely free and open-source... though I made it for my Markdown-based repositories. Give the Playground a try, and let me know what you think about it!
