I Built a Mac App That Turns Any FTP Server Into a Native macOS Drive

Christian Ahrweiler — Sat, 28 Feb 2026 16:19:06 +0000

I built myCloudDrive — a macOS menu bar app that connects to your own server via SFTP, FTPS, or WebDAV and mounts it as a real drive in Finder. No cloud provider, no subscription, no middleman. Your files stay on your server.  The Problem

I have files on my VPS. I have files on shared hosting. I have files on a NAS. Every time I need something, it's the same dance: open Transmit or Cyberduck, connect, navigate, download, edit, re-upload.

What I actually wanted was simple: my server showing up in Finder like a USB drive.

macOS has had "Connect to Server" for years, but it's flaky, disconnects randomly, and doesn't handle FTPS at all. Third-party mount tools exist but most are slow network filesystems that choke on large files.
I wanted something different: a local drive that syncs — fast local reads, background sync to the server, works offline.  The Architecture

myCloudDrive runs as a menu bar app and does three things:

Creates a sparse disk image and mounts it at /Volumes/myCloudDrive — it shows up in Finder's sidebar under Locations, just like an external drive
Syncs bidirectionally with your server using a three-way merge algorithm (local state vs. remote state vs. journal of last known sync)
Watches for changes via FSEvents and syncs automatically within seconds

The sync engine supports three protocols:

SFTP (SSH) — via libssh2
FTPS (FTP over TLS) — via curl
WebDAV (HTTP/HTTPS) — via URLSession

Why Not the Mac App Store?

I tried. The app's architecture is fundamentally incompatible with the MAS sandbox:

hdiutil (creates the disk image) — sandboxed apps can't execute system binaries
/usr/bin/curl (FTPS) — same restriction
FSEventStream on /Volumes/ — sandboxed apps can't watch paths outside their container

I also attempted Apple's File Provider extension (the "proper" way to add virtual filesystems on macOS). After weeks of fighting its poorly documented, buggy API, I abandoned it. The sparse disk image approach just works.

myCloudDrive is notarized by Apple and distributed directly from myclouddrive.app. No Gatekeeper warnings, no sketchy unsigned binary. Many great Mac apps ship this way — Transmit itself left the MAS years ago.

Privacy by Architecture

This isn't a feature toggle. It's how the app is built:

No account creation. You enter your server credentials, that's it.
No cloud relay. The app connects directly to your server. Traffic never touches a third-party service.
No analytics, no tracking, no telemetry. Zero outbound connections except to your own server.
Your files never leave your infrastructure.

Try It

myclouddrive.app — $24.99, one-time purchase, no subscription.
Works with any SFTP, FTPS, or WebDAV server.
Your VPS, your NAS, your shared hosting. Your files, your drive.

Introducing myCloudDrive — Turn Any FTP Account Into a Native macOS Drive

Christian Ahrweiler — Wed, 25 Feb 2026 11:18:19 +0000

myCloudDrive is a macOS app that turns any FTPS or SFTP account into a native drive in Finder. Your server appears like an external disk, ready for drag-and-drop access.

Whether it’s web hosting, a VPS, a NAS, or client infrastructure — if it supports secure FTP, it works. Your files stay exactly where they are. myCloudDrive simply connects your Mac directly to your existing storage, giving you full control without vendor lock-in or subscriptions.

Your storage. Your server. Native on macOS.

🚀 ATECmap — Cookie-Free, Privacy-First Web Maps

Christian Ahrweiler — Tue, 06 Jan 2026 16:13:37 +0000

Embedding maps on your site often means loading trackers, cookies, and third-party scripts — which can slow pages and trigger GDPR consent banners. What if you could embed a map

❌ No cookies, no tracking, no logging — ever.
🔐 GDPR / DSGVO compliant by design — no consent banner required.
⚙️ Provides map data you can embed anywhere or use via API.
🧭 Supports custom map icons and locations.

For devs, this means you can add rich location features to your site without worrying about intrusive trackers or slowing down performance.

🧠 Why This Matters

Most embedded maps pull from major providers but often at the cost of user privacy (tracking pixels, cookies, etc.). With ATECmap, all the map tiles and interactions are served without third-party tracking, keeping you and your users compliant without annoying consent UIs.

It’s especially helpful for:

Websites that must stay clean and compliant (GDPR focus)
Projects where user privacy and minimal footprint are priorities
Devs who want an alternative to big map providers without trade-offs

🚀 ZeroConsent (ZCA) — Ditch the Cookie Banner, Keep the Trust

Christian Ahrweiler — Tue, 06 Jan 2026 15:09:50 +0000

Almost every site in the EU feels forced into the “cookie banner” treadmill — blocking content until a user clicks a confusing choice, or polluting analytics with consent noise. But what if you didn’t need a banner at all? 💭

Introducing Zero-Consent Architecture (ZCA) — a new compliance approach and certification offered at zeroconsent.eu that helps you build privacy-first sites that don’t set non-essential trackers before consent. The result: no cookie banner, faster pages, and provable privacy by design.

https://zeroconsent.eu

🧠 What ZCA Is

Zero-Consent Architecture is about:

❌ No non-essential cookies or identifiers before consent
🔒 No tracking, fingerprinting, or pop-ups by default
📜 A public ZCA Certificate you can link on your site
⚡ Better UX and performance — fewer banners, fewer blockers
✅ Compliance based on what actually happens on your domain

Instead of layering a consent banner over existing trackers, ZCA flips it: if you aren’t setting anything that requires consent, you don’t interrupt users. You prove it.

📈 Why This Matters

Under GDPR and related EU rules, tracking cookies and identifiers generally require freely given, informed, specific consent before they’re set. Banners became the default workaround — but they often annoy users, slow sites, and create legal ambiguity.

Zero-Consent Architecture takes a different path: compliance by design, not by overlay. That reduces legal surface area and improves speed and trust — no modal, no nag screen, and no “consent fatigue.”

🚀 WP Mega Cache — Supercharge Your WordPress Performance

Christian Ahrweiler — Tue, 06 Jan 2026 15:06:42 +0000

Slow page loads are one of the biggest pains for WordPress sites — they hurt SEO, increase bounce rates, and frustrate users. Caching plugins solve this by serving static versions of pages instead of rebuilding every request. That drastically reduces load time and server resource usage.

Today I’m excited to share WP Mega Cache — a fast, flexible page cache plugin designed to get WordPress sites super responsive with minimal configuration.

https://wpmegacache.com

⚡ What WP Mega Cache Does

🔁 Extremely low response times — caching can drop processing from ~130 ms to ~0.25 ms in real cases.
🧠 8 storage backends — APCu, Redis, Memcached, Disk, MariaDB, MySQL and more.
🛍 WooCommerce support & custom post types ⚡
☁️ CDN integrations (Cloudflare, Bunny.net) for global delivery.
🗣 Multilingual support (Polylang, WPML, TranslatePress).
🧹 HTML minify, cache priming, and more performance tweaks.
📦 Free basic version + optional one-time Pro license (no subs).

🧠 Why This Matters

A good cache plugin doesn’t just store files — it improves server speed, reduces CPU and memory usage, and delivers content faster for your visitors. That’s crucial for SEO, Core Web Vitals, and overall UX.

WP Mega Cache focuses on real performance, with advanced storage options and simple setup — even on shared hosting.

🚀 EMDR.chat — Secure Teletherapy with Integrated EMDR Stimulation

Christian Ahrweiler — Tue, 06 Jan 2026 15:04:01 +0000

EMDR (Eye Movement Desensitization and Reprocessing) is a structured psychotherapy technique used to help clients process and heal from traumatic memories and emotional distress. It involves bilateral stimulation (like guided eye movements or visuals) while working through trauma with a trained therapist.

Today I’m excited to share EMDR.chat — a teletherapy platform designed specifically for secure, reliable EMDR sessions online. https://emdr.chat

🧠 What It Is

EMDR.chat is a peer-to-peer video conferencing tool tailored for EMDR therapists and clients:

🔒 Secure, GDPR-compliant video calls
🎯 Built-in EMDR visual stimulation tools — no external devices needed
🌐 Works across browsers & OS (Chrome, Edge, Safari, Firefox, macOS, Windows, Linux)
📅 Session scheduling & reusable session credentials
⚡ Reliable P2P with relay fallback for connection stability
💼 Designed for therapists — secure and private by default

It removes the need for separate video tools + physical EMDR devices and lets clinicians focus on the therapy.

🤝 Why this matters

Virtual therapy has become an important part of accessible mental health care — and EMDR sessions are no exception. Online tools that support real EMDR workflows (including bilateral stimulation) help clinicians meet clients where they are without sacrificing safety or experience.

EMDR itself is widely used and studied as a method to help people reduce distress related to traumatic memories and associated symptoms.

I Built FoxyFy — A Modern, Performance-First Web Platform

Christian Ahrweiler — Tue, 06 Jan 2026 09:41:59 +0000

If you’ve ever wrestled with complex server stacks, slow CDNs, or fragmented DNS tooling, you’ve been there: too many moving parts and too many knobs to turn.

I Built screen2.link to Share Screenshots Without Uploading Them Everywhere

Christian Ahrweiler — Tue, 06 Jan 2026 09:38:08 +0000

Sharing a screenshot sounds simple — until it isn’t.

Most options mean:

Uploading to a third-party service
Creating an account
Leaving images around forever
Accidentally oversharing more than you intended

I wanted something faster and more disposable.

So I built screen2.link.

What it does

📸 Share screenshots with a single link
🕳️ One-time or temporary access
⏳ Optional expiration
🚫 No accounts, no feeds, no tracking
⚡ Lightweight and fast

Open it, view it, and it’s gone.

Why I made it

Screenshots are often:
Debug output
Error messages
Internal tools
Temporary context

They don’t need to live forever in chat history, cloud albums, or random image hosts.

This is for the “can you look at this real quick?” moments.

Who it’s for

Developers sharing bugs or logs
Teams collaborating asynchronously
Anyone who wants ephemeral screenshots instead of permanent uploads

Try it / feedback welcome

👉 https://screen2.link/

I’m actively iterating and would love feedback — especially around UX, edge cases, or workflows you wish this fit into better.

Built and shared in the spirit of the DEV Community ❤️
