7 Free Tools We Built Because the Alternatives Were Not Good Enough

Bandwidth limiting. CPU capping. Port management. Clipboard history. Log tailing. Startup cleanup. A launcher that ties them together. Each one is a portable .exe — no installer, no account, no telemetry. All built with Claude Code in a single session each.

Bandwidth & Network

Control what eats your upload/download bandwidth. Essential when running cloud syncs, builds, and AI tools simultaneously.

#1 Pick

Bandwidth Governor

Ours

Rate-limit upload/download per-app via Windows QoS policies. Auto-detect your speed, cap Claude or OneDrive to a percentage, use presets. Portable .exe.

Free & open source

NetLimiter

The established player. Per-app bandwidth rules with a clean GUI. Good software, but $30 for a license. Bandwidth Governor does the same thing for free via QoS.

$30

Port Management

See what is listening on localhost and kill it. No more netstat | findstr guesswork.

#1 Pick

Port Pilot

Ours

Visual localhost port manager. Every listening TCP port, the process that owns it, stack detection (React, Django, Docker, etc.), one-click kill. System tray.

Free & open source

TCPView

Microsoft Sysinternals classic. Shows all TCP/UDP endpoints with process names. More detail than Port Pilot but no stack detection, no pinning, more complex UI.

Free

Process Control

Cap CPU and memory usage per-app so one runaway process does not bring down your machine.

#1 Pick

Process Governor

Ours

Cap CPU via processor affinity, cap memory via Job Objects. Per-app rules that persist. Portable .exe, system tray, real-time monitoring.

Free & open source

Process Lasso

The OG process optimizer. ProBalance auto-throttling is genuinely smart. Free tier works but nags. Pro is $25. Been around since 2006.

Clipboard Management

Searchable clipboard history with secret detection. Because Ctrl+C only remembers one thing.

#1 Pick

Clipboard Vault

Ours

Full clipboard history with search, category filtering (code, URLs, secrets), API key auto-detection, and pinned favorites. Portable.

Free & open source

Ditto

The long-standing open-source clipboard manager. Good search, syncs across machines, well-maintained. Does not have secret detection or category filtering.

Log Viewing

Tail multiple log files with color-coded levels, regex search, and tabs. The console.log upgrade.

#1 Pick

Log Tailer

Ours

Multi-file log tailing with color-coded levels (ERROR red, WARN yellow, INFO blue), regex search across all open files, tabbed interface, smart auto-scroll.

Free & open source

BareTail

A classic log tail tool for Windows. Fast, minimal, handles huge files. But single-file only, no regex, no color coding by log level. Free version is limited.

Startup Management

See everything that launches at boot. Disable the bloat. Measure the improvement.

#1 Pick

Startup Sentry

Ours

Scans registry Run keys + startup folder. Enable/disable entries non-destructively. Impact rating, publisher info, file paths. Clean, focused UI.

Free & open source

Autoruns (Sysinternals)

The nuclear option. Shows everything that auto-starts — drivers, codecs, shell extensions, scheduled tasks. Overwhelming for most developers but unmatched in depth.

Free

Code Editors & AI

Where the actual coding happens. The editor and the AI that makes it 10x faster.

Essential

VS Code

The default code editor for a reason. Extensions ecosystem, integrated terminal, Git integration, remote development. If you are reading this, you probably already use it.

Free & open source

Game Changer

Claude Code

Anthropic's CLI for Claude. This is what I used to build every tool in the Desktop Suite — each one in a single session. It reads your codebase, understands context, writes real code, and runs terminal commands. It changed how I build software.

$20/month (Pro) or API usage

GitHub Copilot

AI autocomplete inside VS Code. Good for boilerplate, test generation, and when you know what you want but do not want to type it. Works best as a complement to Claude Code, not a replacement.

Free for open source / $10/month

Hosting & Deployment

Where the code goes after you write it. Git push, auto-deploy, done.

This Site

Vercel

The best hosting platform for Next.js apps. Git push to deploy, preview URLs for every PR, edge functions, analytics. This site runs on Vercel.

Free tier / $20/month Pro

Essential

GitHub

The center of gravity. Source control, issues, PRs, Actions for CI/CD, Copilot, Packages. Every tool in the Desktop Suite is hosted on GitHub.

Free for public repos

Netlify

Great alternative to Vercel for static sites and Jamstack apps. Generous free tier, form handling, serverless functions. Slightly behind Vercel for Next.js specifically.

Free tier / $19/month Pro

The Philosophy

If It Does Not Exist, Build It. If It Exists but Costs Money for No Reason, Build a Free One.

Every tool in the Cloud Nimbus Desktop Suite started as a personal annoyance. Bandwidth getting eaten. Ports conflicting. CPU pegged. Clipboard history gone. Each time, I looked for a free tool. Each time, the options were either paid, abandoned, bundled with bloat, or designed for a different era.

So I pointed Claude Code at each problem and built a tool in a single session. Portable .exe. No installer. No account. No telemetry. Open source. The way developer tools should work.
