Keyflow

What it does

Keyflow gives indie developers a full license-key system without hosting a server. Generate cryptographic keys, validate them in under 30ms, track activations per device, and revoke access instantly from one dashboard. Connect Stripe for automatic key delivery on every sale, or integrate via Python, JavaScript, or C# SDKs. Unlike DIY scripts or heavyweight enterprise tools, Keyflow is built specifically for solo devs shipping desktop apps and plugins.

Générez, validez, suivez et révoquez les clés de licence de votre logiciel. Branchez votre boutique : les clés partent automatiquement à chaque vente. SDK Python, JavaScript et C#.

Keyflow génère, valide, suit et révoque les clés de licence de ton logiciel. Tu branches ta boutique, les clés partent toutes seules. Tirée du générateur cryptographique du système, à l'instant. Alphabet sans I , L , O ni U . Tu vends un logiciel. Il te faut donc des clés de licence : les générer, vérifier qu'elles sont valides au démarrage, compter les machines, couper celles qui ont été remboursées ou partagées. C'est un serveur à écrire, à héberger, à maintenir, à sauvegarder. Du travail qui ne rend ton logiciel…from appkeyflow.com

  We built Tapflow for devs, designers, PMs, and tech folks who’ve been sitting on internal docs, templates, and systems — but never productized them. Upload a PDF, notes, or workshop deck, and Tapflow drafts a structured product (with chapters, teaser and pricing plans). It’s good for AI kits, onboarding guides, design systems, and frameworks. You can sell through Stripe, LemonSqueezy, or PayPal. Real-time collaboration is in early beta. No site builder, no LMS — clean design and just focused tools to ship. Fully bootstrapped and just launched on PH today →…

  Hey HN, A few months ago I realized licensing my app wasn't as straightforward as I expected. There was too much setup just to create a license, and the customer experience was not great. All I wanted was for licenses to be generated automatically when I got paid, and for customers to manage their own licenses. So I built Keyforge, a simple software licensing platform for developers. It integrates with Stripe so that licenses are created automatically when someone purchases or subscribes to your product. There's also a self-serve customer portal where users can manage their licenses,…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
