## What it is
SignTools is a free, self-hosted platform for signing and sideloading iOS, iPadOS, and macOS apps without needing a computer on hand. It pairs a web service (hosted anywhere) with a macOS builder that performs signing using official Apple software, and supports OTA installation directly to devices.

## Use cases
- sideload ipa apps to iphone without a computer
- self-host a service to sign ios apps
- sign and install apps over the air to ipad
- inject tweaks into ios apps while signing
- manage multiple signing profiles and entitlements for ios apps
- resign unsigned ipas using a developer account or provisioning profile

## When to choose
- you want to sideload iOS apps without jailbreaking or keeping a computer connected
- you need reliable signing via official Apple tooling on a macOS builder
- you want a mobile-friendly web interface to upload, sign, and install apps OTA
- you need support for provisioning profiles, entitlements, and tweak injection

## When to avoid
- you have no access to a macOS machine to run the builder component
- you want a public app catalog or a turnkey hosted service
- you only need to sign apps occasionally and prefer a simple desktop tool
- you cannot self-host services or manage Docker deployments
