leaf – a terminal Markdown previewer with a GUI-like experience: SKIP, 42/100 | Ideas Lab

A terminal-based Markdown previewer that bridges the gap between CLI workflows and visual document rendering for developers who live in their terminals.

The pain

Developers working in terminal environments (SSH, remote servers, minimalist setups) lack a seamless way to preview Markdown formatting without context-switching to GUI applications or web browsers.

The gap

Existing solutions either require leaving the terminal (browser preview) or provide poor visual rendering (inline terminal output). No tool elegantly combines terminal-native workflow with GUI-quality Markdown visualization.

Build angle

Start with power users (DevOps, SREs, technical writers on remote machines), validate willingness to pay, then expand to broader developer audience if traction emerges.

Strengths

Solves a real friction point for terminal-native developers
Low barrier to distribution (CLI tool, easy installation)
Clear differentiation from existing Markdown tools
Potential for strong developer community adoption
Extensible architecture (plugins, themes, export formats)

Risks

Niche market, terminal-only Markdown preview may have limited TAM
Competing against free alternatives (less, bat, pandoc + browser)
Monetization unclear, hard to charge for developer tools
High churn risk if feature set becomes stale
Requires ongoing maintenance for Markdown spec updates
May be solved adequately by existing tools (Neovim plugins, tmux + browser split)

Fly Labs Method

Is the pain real, is there a gap, is it the right time, can one person build it.

Every CEO and CFO change at US public companies, live from SEC

Built this solo. It watches SEC filings for executive and board changes, extracts the data, and shows it in real time. 2,100+ changes in the last 30 days. The comp data is interesting: average new CEO total comp is $8.4M across 284 appointments. The /explore page is fully open, no login needed.

µJS, a 5KB alternative to Htmx and Turbo with zero dependencies

I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo.It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single <script> tag, one call to `mu.init()`. No build step, no dependencies.Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element.At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.Playground: https://mujs.org/playgroundComparison with HTMX and Turbo: https://mujs.org/comparisonAbout the project creation, why and when: https://mujs.org/aboutGitHub: https://github.com/Digicreon/muJSHappy to discuss the project.
