Client-side email renderer, but remove.bg-style single-purpose tool—MJML and Litmus do this.
Renders email HTML inside an iframe with client-specific CSS filtering (Gmail vs Outlook vs raw), responsive device presets, and a handy 102KB Gmail clipping warning — small but pragmatic features that speed up local iteration. Zero runtime dependencies, TypeScript types and SSR compatibility make it easy to drop into modern Vue/Nuxt stacks; don’t expect it to fully replace real-client testing services like Litmus, but it’s an excellent dev-time preview tool.
Another AI email wrapper in a sea of Superhuman and Shortwave clones.
Local-only alias generator, but Gmail's built-in plus addressing does 90% of this.
Vim keybindings for Minesweeper—fun novelty, but limited staying power beyond niche.
