OpenSyntaxx

OpenSyntaxx is a software company that develops local source recovery tools for iOS application analysis. Its primary product is iosy, a standalone command-line interface (CLI) tool that decompiles decrypted iOS app packages (IPA files) into readable Swift project output. The tool runs entirely on the user's local machine — across macOS, Windows, and Linux — without uploading the IPA file to any remote server or cloud service. Decompilation is performed offline, and the resulting Swift project (including files, folders, resources, and app artifacts) can be reviewed in any local code editor. Output is deterministic, meaning the same input and iosy build version will consistently produce the same output files. iosy is positioned for use cases involving authorized iOS app inspection, including: - Security reviews of iOS app behavior at the source level - Auditing third-party SDK usage and integration points - Analyzing legacy iOS apps where original source code is unavailable - Professional and client-facing app review work OpenSyntaxx offers three pricing tiers: a free trial (providing 10% of Swift file output for evaluation), an Individual plan at $30/month for personal research, and a Commercial plan at $300/month for business, client, and company projects. Automation, CI/CD pipeline use, batch processing, redistribution, and service delivery to customers require a separate commercial agreement. The web account is used solely for license activation, subscription management, and billing. The decompilation product itself operates as a standalone offline tool. OpenSyntaxx describes its focus as building local source recovery tools for companies and individual researchers who need readable Swift output from apps they are authorized to inspect.
