NativeAppTemplate 2.0 - Native iOS + Android + Rails boilerplate, now open source

Most boilerplates pick one platform. We pair true native iOS (SwiftUI) + Android (Compose) with a Rails 8.1 API — three platforms, one stack. What's new in 2.0: the Rails API is now fully open source (MIT), plus iOS 26 + Liquid Glass support, Claude Code-ready CLAUDE.md guidance, Rails 8.1 upgrade. Stand-out: true native (not RN/Flutter), pay-once (no subscription), production-tested (extracted from a live App Store/Play Store app), free OSS clients to evaluate.

People are switching from OpenAI to Claude following Sam Altman's announcement today.

TL;DR: Anthropic refused to sign a contract with the Pentagon that would have allowed the U.S. military to use all of its models without restrictions. Anthropic insisted on an exception, and brace yourself, that its models cannot be used: 1) for mass surveillance of citizens, 2) for autonomous killing. Now the administration is threatening that if the founder of Anthropic doesn't change his mind by a certain date, they will come after him.

Google, OpenAI, and Musk (Grok) have all signed the contract.

Following Sam Altman's announcement over the past few hours, people have been speaking out massively about cancelling their OpenAI subscriptions and subscribing to Claude.
