Coolidash puts your self-hosted Coolify instances in your pocket. Connect one or more Coolify servers over HTTPS with an API token, then watch and control your infrastructure from your iPhone. WHAT YOU CAN DO ⢠See applications, services and databases in one filterable list ⢠Start, stop and restart any resource ⢠Redeploy an application, or rebuild it without cache ⢠Read build logs, with live refresh while a deployment runs ⢠Check machine health: reachability, proxy and resource counts ⢠Revalidate a server that went unreachable ⢠Get notified when a build starts, succeeds or fails BUILT FOR PEOPLE WHO SELF-HOST Your API tokens never leave the device. They live in the iOS Keychain and are never written to files or logs. Coolidash talks straight to your own server: no Coolidash backend, no proxy, no third party in the middle. Every sensitive action - stopping a service, restarting a database, redeploying - asks for Face ID or your passcode first. Coolidash is an independent app. It is not affiliated with, endorsed by, or connected to the Coolify project. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is in-app purchases: Coolidash at none against OpenAPI Viewer's 3. OpenAPI Viewer's advantage is device support (3 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.
