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

Fleet Orchestrator

When a vessel fails three times consecutively, it is quarantined at the circuit level. This helps prevent cascading failures.

This is a stateless coordination hub for Cocapn Fleet. You host it on your Cloudflare Workers account. It coordinates distributed agent fleets on the edge.

Live Reference Instance: https://the-fleet.casey-digennaro.workers.dev

Why This Exists

Existing orchestrators assume you want a third party to run your control plane. This is built for teams that prefer to fork and modify code rather than integrate a proprietary SaaS. You maintain full control over your vessel registry and coordination logic.

Quick Start

  1. Fork this repository.
  2. Deploy to Cloudflare Workers. You need a Cloudflare account and the wrangler CLI.
    npx wrangler deploy
  3. Configure your vessels to send heartbeats and requests to your new orchestrator URL.

Architecture

Stateless edge coordination using Cloudflare Workers and its Edge KV for persistence. There are no runtime npm dependencies, message brokers, or external background services. All coordination is request-driven.

Features

  • Vessel Registry & Discovery: Vessels register via heartbeats. You can discover peers by their declared capabilities or tags.
  • Circuit Quarantine (HCQ): Isolates vessels after 3 consecutive execution failures to limit blast radius.
  • Execution Bonds: Creates a lightweight audit trail for delegated units of work without storing full message content.
  • Cross-Vessel Messaging: Supports broadcast and direct peer-to-peer messaging.
  • Passive Health Checks: Vessel health is inferred from normal request success/failure rates.

One Specific Limitation: Cross-vessel messaging is best-effort and may occasionally duplicate or drop messages under very high concurrent load. It is not a guaranteed delivery system.

What This Is Not

  1. A fully managed service. You are responsible for deployment, monitoring, and any modifications.
  2. A magic auto-scaler. It coordinates existing vessels; it does not create or destroy them.
  3. An analytics platform. It provides operational coordination, not detailed observability.
