Licensing | TheGalaxyDB

How it works

Three steps. No surprises.

Get a license key. Register the domains (browser) or app bundle IDs (iOS / Android) you want to use it on. Your key only works on approved properties nobody else can render on your quota.

Render galaxies

Call the GLEN render endpoint with your key. Galaxy data type, distance, morphology, magnitude returns instantly. Pass story=true to get the named-galaxy narrative in the same response.

Scale with your users

No per-install fees. No device tracking. Monthly quota resets on the 1st. Overages bill at your tier’s rate. When your app grows, you move up a tier the key stays the same.

SDK tiers

Start free. Scale when you’re ready.

Every tier includes browser, iOS, and Android. No separate keys per platform.

Dev

Free Trial

1,000 renders / month

Blocked at 1,000 upgrade to go live.

Integration and prototyping only. Enough to verify the SDK works in your environment before committing to a tier.

Enterprise

Custom Volume

Negotiated renders / month

Any platform, any scale. Custom volume rates, dedicated SLA, integration support, and negotiated terms for high-volume apps or large user bases.

Get in Touch

One render = one API call no per-install fees, no device tracking, no revenue share.
Galaxy Stories included at Indie and above, returned in the same render response at no extra charge.

Galaxy Stories

Narratives for the named sky. Included.

Iconic, widely recognized galaxies, Andromeda, the Whirlpool, the Sombrero, and more, each carry a curated narrative their structure, their physics, their place in the catalog. Pass story=true in your render call and the text comes back in the same response.

No second endpoint. No extra charge. No tokens to manage. Your users tap Andromeda they get the visual render and the story in one call. Available at Indie and above.

GET /render
key = your_license_key
galaxy = ANDROMEDA
story = true

{
"galaxyData": { ... },
"story": "Andromeda spans
six full moons across
our sky despite sitting
2.5 million light-years
away the nearest large
galaxy to our own..."
}

One key. Every platform.

Register your domains and bundle IDs under a single license key. The same key covers your website, your iOS app, and your Android app.

🖶

Browser Embed

WebGL2 in any modern browser. Register your domain your key only works on approved origins. Zero install, zero download for your users.

🆕

iOS Native

Swift or Objective-C SDK. Register your app bundle ID we verify every request against it server-side.

🤖

Android Native

Kotlin or Java SDK. Register your package name same validation model as iOS, same quota pool.

Developer questions

What exactly counts as one render? ▾

One render is one call to the GLEN galaxy data endpoint whether you are rendering a spiral galaxy, an elliptical galaxy, an irregular galaxy, or a galaxy merger. If your user opens a galaxy detail view, that is one render. If they close it and reopen it, that is another. A render is a request, not a page load or a session.

Does one key work for browser, iOS, and Android? ▾

Yes. You register all your approved properties (domains and bundle IDs) under one license key. Renders from any of them count toward the same monthly pool. If you need separate quotas per platform, contact us Enterprise plans can be structured that way.

What are Galaxy Stories and how do I use them? ▾

Galaxy Stories are curated narratives for the sky's most iconic, widely recognized galaxies their structure, physics, catalog position, and what makes them distinct. To get one, pass story=true in your render call. The story text comes back in the response alongside the galaxy data. There is no separate endpoint and no extra charge. Available at Indie tier and above.

What happens if I exceed my monthly quota? ▾

Overages bill at your tier rate at the end of the billing period no throttling, no interruption to your users. Dev is the exception: Dev keys are hard-blocked at 1,000 renders and cannot exceed that. If you are regularly hitting your quota, it is time to move up a tier.

Can I use a Dev key in production? ▾

No. Dev keys are for integration and prototyping only. They are blocked at 1,000 renders per month and should not be shipped in a production app or site. Once you are ready to launch, upgrade to Indie or higher and we will issue a production key for your registered properties.

Can I change tiers as I grow? ▾

Yes. Upgrades take effect immediately. Downgrades take effect at the start of the next billing cycle. Your license key does not change when you switch tiers no code changes required on your end.

I build for observatories and planetariums. Which tier fits? ▾

If you are embedding GLEN in a kiosk, dome display, or museum exhibit you are building for a client, you likely want Enterprise custom volume, a dedicated SLA, and terms that cover installation and handoff. Contact us with your setup and we will structure the right arrangement. If the venue itself wants to use TheGalaxyDB directly without custom development, point them to the Academic or Institution plan on the pricing page instead.
