SkyRadar – Technology that helps you conquer the skies

SkyRadar is a specialized weather forecasting platform for landscape photography, astronomy, and nature enthusiasts, developed independently in Vietnam.

Instead of just answering "Will it rain tomorrow?", SkyRadar focuses on more practical questions: Where can I photograph the Milky Way tonight? Where should I go to hunt for sea clouds this weekend? Will today's sunset have beautiful red hues? Is a trip hundreds of kilometers away worth doing?

To answer these questions, SkyRadar combines meteorological, astronomical, topographical, and light pollution data, then transforms it into visual indices on a scale of 0–100%, making it easy for users to make decisions without needing specialized knowledge.

Distinctive technology

SkyRadar uses data from various meteorological models such as ECMWF, GFS, ICON, and JMA, combining specialized evaluation algorithms:

Astro Score: Evaluates the ability to observe and photograph astronomical phenomena based on cloud layers, atmospheric clarity, moonlight, light pollution, and celestial object positions.

Burn Score: Analyzes the potential for sunrise and sunset colors based on cloud structure, solar angle, and light obstruction.

Cloud Hunting: Assesses the conditions for cloud sea formation based on meteorology and topographical features.

3D Raycasting: Analyzes the impact of cloud layers and terrain from the line of sight, rather than just evaluating the weather at a single point.

The core point of SkyRadar is not to display more data, but to turn complex data into truly useful conclusions.

Feature ecosystem

In addition to an interactive weather map, SkyRadar integrates many tools:

Virtual Sky: Simulates the sky and the positions of celestial bodies in real-time or at a selected time.

Arch Planner: Plans photo composition with the Sun, Moon, and the Milky Way.

Light Pollution Map: A map of light pollution and categorization of sky darkness according to the Bortle scale.

Kèo Thơm: Automatically searches for locations with favorable weather conditions within hundreds of kilometers.

Weather Route: Analyzes the weather along the travel route.

All aimed at a unified experience: Find locations, choose times, assess conditions, and plan before departure.

Autonomous technology with optimal costs

SkyRadar is developing the SkyRadar Weather API, which autonomously receives and processes global meteorological model data while calibrating with real observation data in Vietnam.

The operating infrastructure mainly runs on Cloudflare Workers, Containers, and R2, with the aim of optimizing costs, scalability, and reducing dependence on external data providers.

Notably, SkyRadar is developed by an indie maker with extensive support from AI in programming, testing, and operations. This is evidence of the ability to transform specialized knowledge, practical experience, and AI into a complete technology product without needing a large development team.

From individual needs to community

SkyRadar was founded by Duy Chris, an IT professional and an enthusiast of landscape photography and astronomy.

Starting from the need to find good photography conditions during trips, SkyRadar has evolved into an application with over 2,000 downloads and approximately 1,200–1,400 active devices as of October 2026.

Algorithms are continuously improved through observational data, community feedback, and real-world validation.

Vision

SkyRadar aims to popularize in-depth analytical tools for all nature lovers while gradually expanding into international markets.

The development philosophy is very simple:

The more complex the technology inside, the simpler the user experience outside.

We cannot create a beautiful sky. But we want to help everyone have the opportunity to find it.
