Hey Product Hunt community! 👋 I'm Gautam, maker of DevAuthKit. Almost every developer has a "graveyard" of side projects on GitHub. A year ago, I started building DevAuthKit to solve my own frustration: why does setting up simple email OTP, JWT tokens, and session handling in Express require 100+ lines of repetitive boilerplate, or paying $25+/month for heavy third-party SaaS auth? But like many projects, life got busy, and it sat untouched for an entire year. Yesterday, I decided to open the repository again. I completely overhauled the engine—added cryptographic security, dual JWT/Session authentication, brute-force shields, and built a companion Client SDK that makes frontend auth 3 lines of code. I pushed v1.1.0 to npm and shared a quick post on X. The response from fellow builders made me realize how many developers just want a clean, self-hosted, vendor-free auth toolkit they can control. Today, I'm excited to bring it to Product Hunt! 🛠️ What makes it special: 1) Zero-Setup Dev Mode: You can test authentication immediately in your terminal—no email credentials needed. 2) Universal Client SDK: Works in React, Vue, Next.js, or plain HTML. 3) 100% Open Source: MIT-licensed, no telemetry, no paywalls. I would love to hear your thoughts, feedback, and what features you’d love to see next (OAuth, Magic links, Redis adapter?). Thank you for your support! 🙌
