Kling.to – Self-hosted email marketing with full data ownership
I'm Caesar, and I built kling.to because I believe marketing automation should be accessible to everyone without sacrificing data ownership. Kling is a self-hosted email marketing platform that lets you run campaigns, build automation workflows, segment audiences, and track attribution while keeping full control of your customer data. It deploys via Docker and uses MongoDB with BullMQ for job scheduling. Core capabilities: - Visual workflow builder for abandoned cart recovery, win-back campaigns, and post-purchase sequences - Multi-channel messaging (email, SMS, WhatsApp, push notifications)…
In plain words
Kling.to is a self-hosted email marketing platform that gives users full control of their customer data. It provides visual workflow builders for campaigns like abandoned cart recovery and post-purchase sequences, multi-channel messaging across email, SMS, WhatsApp, and push notifications, and attribution tracking. The platform includes audience segmentation, template management with personalization, and real-time deliverability monitoring. It deploys via Docker and is designed for businesses seeking marketing automation without relying on third-party data hosting.

I'm Caesar, and I built kling.to because I believe marketing automation should be accessible to everyone without sacrificing data ownership. Kling is a self-hosted email marketing platform that lets you run campaigns, build automation workflows, segment audiences, and track attribution while keeping full control of your customer data. It deploys via Docker and uses MongoDB with BullMQ for job scheduling. Core capabilities: - Visual workflow builder for abandoned cart recovery, win-back campaigns, and post-purchase sequences - Multi-channel messaging (email, SMS, WhatsApp, push notifications) - Last-touch and multi-touch attribution tracking - Customer segmentation with purchase history and engagement data - Template management with personalization variables - Real-time deliverability monitoring (sent, delivered, opened, clicked, bounced) I started this project because existing marketing automation tools either lock you into their infrastructure or cost too much for small teams. We're giving businesses the choice to self-host and own their data. The platform is built for e-commerce stores, engineering-led teams, and privacy-conscious organizations that want control over their marketing stack. I'd value feedback on: - Architecture choices (MongoDB + BullMQ for job scheduling) - Deliverability infrastructure for self-hosted setups - Automation workflow UX and trigger logic - Attribution model implementation Demo video: https://youtu.be/hbFjX525AwA Website: https://kling.to Happy to answer questions about the technical implementation or deployment process.

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
