Self-Hosted Alternatives Finder
The Companion App Store includes a curated dataset of self-hosted alternatives to popular proprietary services — helping you find open-source replacements for the tools you already use.
How It Works
The App Store maintains an alts.json dataset that maps proprietary services to their self-hosted equivalents. When browsing apps, you can discover alternatives to services like:
- Google Photos → Immich
- Dropbox → Nextcloud
- LastPass → Vaultwarden
- Notion → BookStack, Outline
- Spotify → Navidrome
- Google Drive → Nextcloud, Seafile
Finding Alternatives
In the Companion Home App Store, look for the alternatives section when browsing apps. Each entry links directly to an installable app in your store, so you can go from discovery to running in a single click.
Contributing
The alternatives dataset lives in the Companion App Store as alts.json. Contributions are welcome — if you know of a self-hosted alternative that’s missing, submit a pull request to the App Store repository.
The alternatives finder is a discovery tool. Not every proprietary service has a perfect 1:1 replacement, but the self-hosted ecosystem is growing rapidly.
