Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

@fnclaude/renderer

Configurable TUI front-end for Claude Code. Bidirectional stream-json driver, repaint-on-toggle visibility filters (Alt+1-8), pretty markdown via glow.

Previously published as fnclaude-renderer on npm. Renamed to @fnclaude/renderer when imported into the fnclaude monorepo.

Status

Pre-v1. Active development. v0 ships the renderer in standalone wrapper mode — fnclaude-renderer ... spawns claude internally, renders the stream.

Goals

  • Replace the Claude Code CLI's fixed output with verbosity presets (quiet / normal / verbose / debug) and per-element show/hide toggles.
  • Repaint past content on toggle — flip a filter and previously-hidden content appears in place; previously-shown content collapses to a header. The transcript is a live view of the event log under the current filter.
  • Pipe assistant markdown through glow when available; raw fallback otherwise.
  • One persistent claude subprocess per session, driven via --input-format stream-json --output-format stream-json. No --resume-per-turn latency.

Install

bun add -g @fnclaude/renderer
# or
npm install -g @fnclaude/renderer

Optional: glow

glow renders assistant markdown with syntax highlighting. If it's on your $PATH it gets used automatically; otherwise raw markdown is shown.

Platform support

Supported on Linux and macOS. Windows support is untested.

Keybinds

| Keybind | Element toggled | |---|---| | Alt+1 | thinking blocks | | Alt+2 | Bash.input (commands) | | Alt+3 | Bash.output | | Alt+4 | Edit.diff | | Alt+5 | Read.content | | Alt+6 | Write.content | | Alt+7 | Task.nested (subagent prompts) | | Alt+8 | errors | | Alt+0 / Alt+9 | cycle preset forward / backward | | Ctrl+L | force repaint | | Ctrl+D | clean exit |

See docs/keybind-spec.md for terminal-specific caveats (especially macOS Terminal.app's Option/Meta handling).
