Questions & Answers

As answered by people managing https://open-gpt.app/ and LunarFrame.pl.

What's the story behind your product?

LunarFrame.pl's answer:

Lunar Frame started as a personal tool. Its creator, Łukasz, regularly photographs the Moon over landmarks and landscape elements, but planning those shots often required switching between several different apps and maps.

The idea behind Lunar Frame was to create one place where a photographer could plan the whole shot: observer position, target, Moon alignment, terrain, camera frame and timing. Over time, the app expanded with saved plans, yearly matrices, frame simulation, custom map objects, eclipses and educational explanations.

The project is still actively developed and shaped by real photography workflows and user feedback.

Who are some of the biggest customers of your product?

LunarFrame.pl's answer:

Since Lunar Frame is currently a free public app and does not require paid accounts, there are no formal enterprise customers to list.

You can enter:

Independent Moon photographers Landscape photographers Astrophotographers Astronomy enthusiasts Lunar Frame community users

What makes your product unique?

LunarFrame.pl's answer:

Lunar Frame combines Moon photography planning, map-based alignments, terrain analysis, frame simulation and eclipse tools in one browser-based app.

Its strongest difference is the workflow around planning a shot with a specific target: you can set an observer and a target on the map, check Moonrise/Moonset alignment, scan multiple dates, use a yearly matrix, compare locations and preview the frame with your camera setup.

Lunar Frame also lets users add simple custom objects or buildings on the map and see them later in the frame simulation, which helps estimate whether a structure or obstacle may affect the planned composition.

Why should a person choose your product over its competitors?

LunarFrame.pl's answer:

Lunar Frame is free, works directly in the browser and can be used on desktop, tablet and mobile without installing a native app.

It is especially useful for photographers who plan Moon shots with specific landmarks, buildings, hills or other targets. Instead of checking one date at a time, users can scan multiple full moons, inspect a yearly matrix, compare several locations and use corridor-style planning to find better observation areas.

It also includes a growing eclipse module with visibility maps, phase timelines, 3D visualization and comparison tools, making it useful not only for Moon alignments but also for planning and understanding astronomical events.

How would you describe the primary audience of your product?

LunarFrame.pl's answer:

Lunar Frame is primarily built for Moon photographers, landscape photographers, astrophotographers and visual creators who want to plan shots where the Moon aligns with a specific object or landscape feature.

It is also useful for astronomy enthusiasts who want to follow full moons, conjunctions, eclipses and other sky events in a more visual and practical way.

Which are the primary technologies used for building your product?

LunarFrame.pl's answer:

Lunar Frame is built as a browser-based web application / PWA.
