    We as developers, build and maintain many services in code, one of them being notification service. In the last 5-7 years, API-to-user communications have exploded across SMS, email, chat apps, mobile, and web push. As a consequence, notification service handling them has become quite complex. Developers spend time building integrations with multiple providers, create templates for each channel, managing scheduling and routing based on preferences, maintaining queues to deliver notifications on time while managing scale. Besides, product teams have poor visibility on notifications as…

    Hello there (General Kenobi's favorite way to start the conversation), I’m Rashid, a sophomore at UT Austin. I built Rejourney.co (https://rejourney.co/) to predict issues with your apps and websites before they happen, based on real user session recordings. Here is a silly video (with cats) on how it works: https://www.youtube.com/watch?v=Z95MDxBXMjk It’s open source, and the post link is the github repo, but here it is again: https://github.com/rejourneyco/rejourney I originally built this because I had a campus freebie finder app that grew…

    Hi guys, I've created an open source web builder framework (https://grapesjs.com) years ago, which I'm still maintaining, and now I'm excited to publish a side project based on it, Grapedrop (https://grapedrop.com). It's a simple web page builder which allows you to design and publish your web pages very quickly. The project is still in beta with a lot of stuff to improve but I'd really like to share it and hear what people think about it and maybe also get some constructive feedback.

    Hey HN, Nir, Gal and Tomer here. Last week, we open-sourced Enrolla (https://github.com/enrolla/enrolla) - feature management for SaaS companies. It makes it easy for developers to control how their product behaves for customers in different pricing tiers. So things like which features are enabled for whom, rate limits and seat limits, but also your customer secrets (with end-to-end encryption), and other configurations. After 15 years of working together at various companies, where we rebuilt the same SaaS foundation layer again and again - we wanted to create something…

    Empower your product manager. Let them decide what the messages to your users say, when those messages are triggered, as well as how they are sent (sms, email, etc.) while you focus on building product features. They'll be able to use trusted providers like sendgrid, twilio and apple so you don't have to worry about message delivery.

    Hey HN, excited to share our open source tool with the community. We wanted to build an open source omnichannel tool where you can design customer journeys with a drag and drop editor. You can use our tool for example to design an onboarding flow so that users who sign up to your site can receive a series of predetermined emails and sms. Give it a spin and let us know how we can improve it. We also made it so you can self host.
