Mateus Mercer - My Toolbox

Things I started using only 3 months ago

Open Source

DAVx⁵

Syncs contacts, calendars and tasks between Android and any CalDAV/CardDAV server, straight into the phone's native apps.

Useful for syncing Monica to my phone contacts.

Free

JustWatch

Streaming guide: search any movie or show and see which services have it in your country, whether to stream, rent or buy, and what just arrived.

Open Source

SD Maid SE

Android cleaning tool: removes leftover files from uninstalled apps, clears caches and junk, finds duplicates and shows what's eating your storage.

Open Source

Mutagen

Keeps folders in sync with remote servers and containers over SSH or Docker, one-way or two-way, with a real local copy that works offline.

I use it to sync some Debian files to my local macOS. It’s reliable, easy to set up and almost instant.

CLI only

Sofa Time

Keeps track of every show and movie you watch, reminds you when new episodes come out, and lets you see what everyone else thought of them.

I migrated here from the now-defunct TV Time. It’s like a social network for movies and series. It’s really fun to watch something and then see other people’s reactions to it.

Open Source

Mole

Cleans caches and logs, fully uninstalls apps with their leftovers, and analyzes disk usage on your Mac from the terminal.

The command-line tool is very simple to use. I was surprised that it cleaned 120 GB from my system. Very effective.

CLI only

Open Source

Cyberduck

Server and cloud storage browser: FTP, SFTP, WebDAV, Amazon S3, Backblaze B2, Azure, OneDrive, Google Drive, Dropbox and more.

It just works. I now even prefer it over FileZilla on Windows.

Free

ego lite

Chromium browser built for AI agents like Claude Code and Codex, letting them automate sites with your logged-in sessions.

A game changer when paired with Claude Code or other agents. It automatically imports your current Google Chrome profile, so you’re good to go.

Open Source

OpenMTP

Android file transfer for Mac: browse and copy files between your Mac and an Android phone over USB (MTP).

You can use it with the Nintendo Switch too; it makes up for macOS’s lack of good MTP support. I still need to reboot macOS sometimes, though.

Open Source

pipensx

Homebrew downloader for the Nintendo Switch.

Open Source

Vorssaint

One menu bar icon doing the job of a dozen paid Mac apps. Local-first.

I’m not kidding: this replaced four other utility apps on my Mac.

Free

Windy

Interactive weather map with wind, rain, temperature and waves, comparing forecasts from several global models.

It plays a sound with every lightning strike, and on phones it vibrates too, which is very cool. I love the Android home screen widgets.
