An Install On Air alternative built around testers

Yes, with no card to start. Free covers builds up to 150 MB, 5 apps with 10 testers each, 2 GB of storage, 5 uploads an hour, and keeps each build for 7 days. Tester invites, feedback, push notifications, CI uploads and iOS over-the-air installs are all included on it — Pro and Studio raise the limits rather than unlocking the distribution flow. Pro is $9 a month (or $90 a year); Studio, built for agencies running several apps, is $24 a month (or $240 a year).

A build uploaded without an account is kept 3 days, 7 days on the free plan, 30 days on Pro, 90 days on Studio. When that runs out the binary is deleted and the link stops resolving — this is a distribution tool, not a backup service. On Pro or Studio you can extend a build's expiry before it lapses or pin it so it never expires; the dashboard shows the countdown on each build and warns you 24 hours out.

No — the link belongs to the app, not to the upload. It always resolves to the newest build, and every earlier version stays reachable from that same page's history, so you can paste it into a brief or a Slack channel once and never update it again. Builds are filed against an app by bundle ID automatically, so nothing has to be organised by hand.

Yes, on any plan. One step — npx appdropper upload build/app.apk, with an API token in the APPDROPPER_TOKEN secret — works on any CI that runs Node 18 or newer, and there are ready-made integrations for GitHub Actions and Fastlane. All of them are clients of a public REST API at appdropper.io/api/v1 if you would rather call it yourself. Upload tokens carry one scope and reach only the apps you tick, so handing one to a client's pipeline does not expose the rest of your account.

Each app's link runs in one of three modes: public to anyone holding the URL, password-protected on Pro or Studio, or invite-only, where everyone except the testers you have added sees a locked page instead of the app. Testers are invited by email and accept or decline, and every invited tester gets an email plus a native push notification when a new version lands. You can switch modes at any time from the dashboard, and the URL does not change when you do.

Yes — an .ipa installs over the air straight from its share page, with no App Store review and no TestFlight invite to wait on. The one Apple rule that still applies is provisioning: an ad-hoc build only installs on devices whose UDID is in the profile it was signed with. App Dropper reads that device list out of the binary at upload time and shows the count on the install page, so a failed install is quick to diagnose. Enterprise-signed builds carry no such restriction.
