IPA Generator Online
for iOS Apps
Fastshot is a cloud-based IPA generator that produces signed IPA files for iOS apps. Build IPA online, sign IPA in the cloud, and export IPA files ready for TestFlight or the App Store — without owning a Mac or installing Xcode. Use it as a standalone IPA builder or as part of the full iOS app pipeline.
What is an IPA Generator?
An IPA generator is a tool that compiles iOS source code into an IPA file — the iOS application archive that Apple devices use to install apps. IPA files contain the compiled app binary, signing certificate, provisioning profile, entitlements, and resources. They are what TestFlight and the App Store distribute, and what any iOS device installs.
Traditionally, you create IPA file output by running an Xcode archive on a Mac, with a paid Apple Developer account, an iOS distribution certificate, a provisioning profile, and the right entitlements. Anyone who has shipped an iOS app knows that a misconfigured signing chain can burn an entire afternoon.
Fastshot is an online IPA creator that runs the whole pipeline in the cloud. You bring iOS source code (written by hand or generated by our [iOS app builder](/ios-app-builder)), and Fastshot acts as the IPA builder — running xcodebuild remotely, applying signing certificates, embedding provisioning profiles, and producing a signed IPA file.
Whether you need to build IPA online for TestFlight, sign IPA for ad-hoc distribution, or simply export IPA for archive, the cloud pipeline handles it. No Mac, no Xcode install, no provisioning-profile detective work.
How the IPA Generator Works
Provide Your iOS Source
Bring an existing iOS project or generate one with Fastshot’s iOS app builder. The IPA generator accepts React Native + Expo projects out of the box and handles configuration automatically.
Configure Signing
Upload your Apple distribution certificate and provisioning profile, or let Fastshot manage signing for you. The cloud IPA builder handles entitlements, bundle IDs, and version codes.
Build IPA Online
Trigger the build. Fastshot runs xcodebuild and the iOS toolchain remotely, producing a signed IPA file in minutes. No local Xcode, no Mac, no waiting for archive uploads.
Export IPA File
Download the signed IPA file. Upload to TestFlight via App Store Connect, distribute ad-hoc to registered devices, or submit to the App Store. Whatever your distribution path, the export IPA file is ready.
IPA Generator Features
Cloud IPA Builds
Build IPA online with no local toolchain. The cloud IPA generator runs the full Apple build chain remotely on every push, so you never wait for a Mac.
Automatic Code Signing
Sign IPA online with a signing certificate, provisioning profile, and entitlements applied automatically. No more "code signing identity not found" errors.
TestFlight-Ready Output
Every IPA file is structured for TestFlight upload — correct bundle ID, version, provisioning profile, and entitlements, ready for App Store Connect.
Ad-Hoc and Enterprise Distribution
Generate ad-hoc IPAs for registered test devices or enterprise IPAs for internal distribution. The IPA builder supports all standard Apple distribution profiles.
Universal IPA (iPhone + iPad)
Produce a single IPA file that runs natively on both iPhone and iPad with adaptive layouts. The IPA generator handles universal builds out of the box.
Build History & Versioning
Every cloud build is logged with a build number, IPA artifact, and signing details. Roll back, re-sign, or re-export any prior build with one click.
