SwellSlots – a grid-based surf forecast application.

Technical Positioning

A visually distinct (Street Fighter 2 UI), user-friendly surf forecast app that consolidates key weather metrics into a scannable, color-coded weekly grid, differentiating itself from 'clinical and cold' existing apps.

SaaS Insight & Market Implications

SwellSlots demonstrates the application of modern web technologies and AI-assisted data curation to a niche consumer market. The use of an 'AI-assisted pipeline' for spot database creation, despite requiring manual curation, highlights the practical limitations and benefits of LLMs in specialized data acquisition. The product's differentiation strategy, focusing on a unique UI/UX ('Street Fighter 2 UI' vs. 'clinical and cold' apps), underscores the importance of user experience in competitive markets. While not directly B2B SaaS, the underlying data pipeline and deployment choices (SvelteKit, TailwindCSS, Hetzner) reflect common development practices that could be scaled or adapted for other data-intensive, visually-driven applications.

Show HN: SwellSlots – Grid Based Surf Forecast App with a Street Fighter 2 UI

I discovered surfing last year in my early 40's its been a journey and a half and more fun than taking up golf at my age.SwellSlots squeezes swell height, period, wind speed/direction, and tide state into a color-coded weekly grid. One glance tells you when conditions are 'good' for the next few days.I wanted it to look completely different to what was out there (UI wise), as most of the forecast apps looks very clinical and cold.Some technical details:- SvelteKit + TailwindCSS 4, deployed on Hetzner (LOVE their cloud-console-ux! So simple)- 2,000+ surf spots worldwide (sourced via a separate AI-assisted pipeline I call "Surf Scout" — got ~80% accuracy, rest is manual curation)- The spot database was its own challenge — Google Maps couldn't distinguish surf beaches from swim beaches, and LLMs got about 75–80% of the way thereI'd really appreciate feedback on:- Is the grid scannable enough on first visit?- Any surf spots missing from your area?- What else would you like to see?EDIT - Formatting
