CompressO is a cross-platform desktop application that shrinks video and image file sizes using proven compression tools like FFmpeg, pngquant, jpegoptim, and gifski, all wrapped in a simple GUI. It is 100% free, open-source, and works completely offline.

It is most valuable when preparing optimized images and videos for websites, such as before deploying assets to production or when Lighthouse/performance audits flag heavy media files. It's also useful for studying how to integrate FFmpeg and other compression binaries into a Tauri-based desktop application.

SlideOps is a pair of Agent Skills for Claude Code and compatible coding agents that turns a repository into a self-contained HTML slide deck (or Markdown doc), then continuously verifies that the deck's quoted code still matches the actual codebase. It includes a dependency-free Python checker that flags drifted citations and generates repair briefs for agents to fix only what changed.

Use it when you need to create technical presentations or documentation about a codebase for stakeholders, onboarding, or architecture reviews. It's especially valuable for long-lived projects where docs must stay truthful as code changes, and its offline, single-file HTML output works well for sharing decks without infrastructure.
