Is Maestral Still Maintained?

No. According to Maestral's own site, as of June 2026 Maestral is no longer actively maintained. The current version will continue to work until certificates expire. That means the app is not abandoned in the sense of being broken today, but it is also not receiving fixes, new features, or security patches. If you are deciding whether to keep using it, the practical question is not "does it run?" but "how long will it keep running, and what happens when it stops?"

What "no longer actively maintained" means here

The site states two things plainly:

• No active maintenance as of June 2026. No ongoing development, bug fixes, or updates.
• The current version will continue to work until certificates expire. The app depends on certificates (for example, for Dropbox authentication and secure connections). When those expire, functionality that relies on them can stop working.

This is a specific and limited guarantee. It does not say the app will work indefinitely, and it does not say it will stop on a fixed date. It says it works until certificates expire — so the useful planning assumption is that Maestral has a finite remaining lifespan tied to certificate validity, not to a version number.

What still works today

Maestral is an open-source Dropbox client for macOS and Linux. Its documented capabilities include:

• Command line interface — view and restore previous file versions, create and revoke shared links, and see a live view of sync activity. Example commands from the site include maestral status and maestral start.
• Lightweight GUI — a native Cocoa interface on macOS and a Qt-based interface on Linux.
• Multiple Dropbox accounts — the CLI allows configuring an unlimited number of accounts by passing a new config name when linking.
• Selective sync and exclusions — exclude individual files via the GUI or CLI, or use an .mignore file in the Dropbox root with gitignore-style patterns.
• No device-limit counting — Maestral is not an official Dropbox app, so it does not count toward the three-device limit for Basic Dropbox accounts.

These features are what you have. There is no roadmap for more.

Implications for long-term use

The security point deserves emphasis without overstating it: an unmaintained client that handles authentication and file sync will not receive updates if a vulnerability is found. That is a general property of unmaintained software, not a claim that Maestral currently has a known vulnerability.

How to decide whether to keep using it

Use Maestral if:

• You need a lightweight Dropbox client on macOS or Linux now.
• You value the CLI, multiple-account support, or the fact that it does not count toward the Basic device limit.
• You are comfortable migrating later, when certificates expire or sync stops working.

Plan to move away if:

• You need guaranteed long-term support or security updates.
• You are deploying it across many machines or in an environment where an unexpected sync failure is costly.
• You want an actively developed client with a maintenance commitment.

Where to check for updates or alternatives

The site itself is the authoritative source for Maestral's status. Check it for any change to the maintenance statement before assuming the June 2026 notice still stands. For alternatives, the relevant comparison points are the same ones Maestral is chosen for: Dropbox support on macOS and Linux, CLI availability, multiple-account handling, selective sync, and whether the client counts toward Dropbox device limits. Evaluate any replacement against those dimensions rather than against Maestral's feature list alone, since the device-limit behavior in particular is unusual and may not be matched.
