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 🙏

Readme

@isomoes/iagent

A web UI that hosts a terminal coding agent (Claude Code / Codex CLI) — run it with one command. The agent's TTY lives on the server (Bun.Terminal), its renderer lives in your browser (@xterm/xterm + WebGL), and a WebSocket is the wire. This package bundles the server and the pre-built UI into a single process that serves everything from one origin.

Run it

npx @isomoes/iagent      # or: bunx @isomoes/iagent

Then open http://127.0.0.1:4517.

Requirements

  • Bun ≥ 1.3.5 on your PATH — iagent is Bun-native (Bun.Terminal is POSIX-only, so Linux/macOS), and the bin runs under Bun even when launched with npx (its shebang is #!/usr/bin/env bun). No Bun yet? npm i -g bun, or see https://bun.sh.
  • The agent CLI it spawns — by default claude (Claude Code). Override with IAGENT_AGENT_CMD.

Configuration

All via environment variables (all optional):

| Env | Default | What | | --- | --- | --- | | PORT | 4517 | Port for the UI + REST + WS (one origin) | | HOST | 127.0.0.1 | Bind address — localhost only; there is no auth (anything that reaches the port already has local RCE) | | IAGENT_AGENT_CMD | claude | Agent command spawned in the PTY | | IAGENT_AGENT_ARGS | – | Comma-separated agent args (e.g. --dangerously-skip-permissions) | | IAGENT_AGENT_CWD | server cwd | Directory the agent starts in |

Example:

PORT=8080 IAGENT_AGENT_CMD=codex npx @isomoes/iagent

Security

The server binds to localhost only and ships no auth token — by design it is effectively RCE-as-a-service, so anything that can reach the port is assumed to already be local. Do not expose it to a network you don't trust.

How it works

@isomoes/iagent is a single Bun-target bundle of the iagent server + shared wire protocol, with the Vite-built client baked in and served from the server's own origin. It therefore has zero runtime dependencies — only Bun itself.
