LibreReplace

Cut recurring Mac software costs without losing the features you need.

Explore 45 commercial Mac apps and 70 open-source comparisons, even without installing the paid app. Choose the features you need, see what each replacement can and cannot do, or scan your installed apps and review recurring costs before you switch.

Local-only · No account · No telemetry · Never removes your existing app automatically

Quick install

Download v0.2.0-preview.1 for macOS or build locally from source. Homebrew: brew install --cask maliroq/tap/librereplace.

Preview distribution: the downloadable app is ad-hoc signed and not Apple-notarized. The Homebrew Cask does not remove quarantine or disable Gatekeeper.

LibreReplace is not another alternatives directory. It can start from a supported installed app or from Explore Alternatives, shows exactly where an open-source replacement falls short, and can conclude KEEP THIS APP when switching would cost too much of your workflow.

Photoshop: compare more than one replacement

LibreReplace shows which features GIMP and Krita support, partially support, or lack.

CleanMyMac: choose what you need to keep

Recommendations respond to your selected essential features. Recurring-cost estimates require user confirmation.

What it does

• Scans /Applications, /System/Applications, and ~/Applications for application bundles.
• Reads only application metadata from Contents/Info.plist during the normal scan.
• Recognizes 45 curated commercial targets using 55 researched bundle-ID mappings plus conservative name aliases.
• Compares 70 open-source alternatives and reports Strong, Partial, or Keep depending on what you need.
• Shows weighted capability coverage, critical missing features, known limitations, source/license evidence, and verification dates.
• Opens verified official download pages or, after confirmation, runs a typed Homebrew action without shell interpolation.
• Shows potential annual savings from user-confirmed recurring costs when a selected Strong open-source edition is free and the old subscription can be cancelled. Hosted services with unverified costs are excluded.
• Exports a local Markdown summary that omits application names by default.
• Supports one narrow migration: Sublime Text preferences → Zed settings, with preview, verified backup, verification, and rollback.

Why it is different

General alternatives directories are useful for discovery. LibreReplace answers a more specific question: can I replace this app on my Mac without breaking the parts of my workflow I care about?

For each supported app, the catalog records capabilities, critical requirements, explicit losses, installation provenance, source/license evidence, and verification dates. Unknown support does not count as parity. Stale evidence cannot produce a Strong recommendation.

Install

Homebrew Cask

Install the current preview with brew install --cask maliroq/tap/librereplace, download the release DMG, or build from source.

LibreReplace v0.2.0-preview.1 is distributed as an ad-hoc-signed, non-notarized Mac app. The Cask does not remove quarantine attributes or disable Gatekeeper. macOS may require you to approve LibreReplace in System Settings → Privacy & Security → Open Anyway.

DMG

Download LibreReplace-v0.2.0-preview.1.dmg from the v0.2.0-preview.1 release.

Build locally from source

git clone https://github.com/maliroq/LibreReplace.git
cd LibreReplace
brew install xcodegen
./Scripts/install_local.sh

The local installer builds and ad-hoc signs the app without using Apple credentials or weakening Gatekeeper. See Building from source and Local verification.

Supported applications

The preview covers 45 commercial targets and 70 open-source comparisons. Decisions adapt to your chosen essential features; they are workflow estimates, not guarantees of identical performance, accessibility, security, support or file-format fidelity.

See the support matrix for every source app, alternative, recommendation level, and major limitation.

Safety and privacy

Scanning and recommendation are local. LibreReplace has no account system, telemetry, analytics, ads, remote inventory service, or background daemon.

The normal scanner does not read Documents, Desktop, Keychain, browser profiles, passwords, project files, or unrelated application data. Installation always requires confirmation. LibreReplace never automatically uninstalls the source app. The migration adapter is preview-first and narrowly constrained to documented non-sensitive editor preferences.

See Privacy, Threat model, and Migration safety.

Known limitations

Catalog coverage is finite, evidence ages, feature coverage is a maintained judgment, and only one migration adapter exists. The preview has not completed Developer ID signing/notarization or a dedicated independent VoiceOver/keyboard-navigation review.

See Known limitations.

Building from source

For the full macOS gate:

python3 dev.py

For portable core/catalog development:

make check

The generated Xcode project is disposable; project.yml is the source of truth.

Contributing

Add or verify an app replacement

Catalog quality matters more than catalog size. Contributions should use primary evidence where practical, record exact workflow losses, preserve critical features, and downgrade uncertain claims rather than guessing parity.

The preview target set is frozen for release; verification and corrections to existing entries are immediately useful. New target proposals should start with an issue until maintainers reopen catalog scope.

See Contributing and Catalog schema.
