Daisuke Adachi's profile on Product Hunt

About

Full-stack engineer with 20+ years of professional development experience, specializing in Ruby on Rails (Hotwire / Turbo / Stimulus) backends that power native iOS and Android clients. I design, ship, and operate all three layers single-handedly — from Rails 8.1 multi-tenant SaaS APIs to App Store / Google Play releases. Former project leader on a Rails web service used by ~50,000 users across ~100 schools. Since 2025 my focus has been AI-driven development with Claude Code and the Claude Agent SDK. I work most effectively in environments where Claude Code is available as a coding assistant.

NativeAppTemplate Agent - One sentence → Rails + SwiftUI + Compose Android. Free, MIT.

Turn a one-sentence spec into a coherent Rails 8.1 API + native SwiftUI iOS + native Jetpack Compose Android implementation — renamed end-to-end, validated across three layers, in under an hour. A Claude Code agent. Free, MIT. CLI, MCP server, or plugin.

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.
