The Shape Of The Spell List Screensaver
The Shape Of The Spell List screensaver charts how many D&D 5e SRD spells exist at each level, from cantrips through to ninth. The distribution is lopsided in a way players feel but rarely see plotted: levels one to three carry most of the list, and by ninth there are barely a dozen. It runs in the browser with nothing to install; press ESC to exit.
How the The Shape Of The Spell List screensaver works
The saver reads dnd5eapi.co, which serves the open-licensed 5e reference data.
No account and no key: the request goes straight from your browser, or from this site's own refreshed copy of the feed where the source does not allow browser access.
Values are drawn on a canvas that resizes with the window, so it works on a laptop or a wall display.
If the source is unreachable the saver says so on screen rather than showing stale numbers as though they were current.
A worked example
Ten bars, one per spell level, each with its count and a rotating example spell named on the right. Low levels dominate because those are the spells a character casts for a whole career; the ninth-level bar is a stub, and each spell in it is a campaign event rather than a combat option.
Settings & tips
- Accent and Background recolour the display without changing the data.
- Add it to a Multi-view grid to watch it alongside other live savers.
- Press ESC at any time to leave fullscreen.
Frequently asked questions
- Why does the saver make ten separate requests?
- Because the API's spell list returns names and a count but no level field, so the only way to get the distribution is one request per level. They are issued in sequence rather than all at once, because the service is free and hammering it ten-wide to save two seconds is rude.
- Is this every D&D spell?
- No — it is the System Reference Document, the openly licensed subset. The published rulebooks contain more spells that are not free to redistribute.
- Is this real data?
- Yes. It comes from dnd5eapi.co, which serves the open-licensed 5e reference data. Nothing is invented or simulated, and if the source cannot be reached the saver reports that instead of drawing something plausible.
- Does it cost anything or need an account?
- No. Every screensaver here is free, runs in the browser and needs no sign-up. This one uses a public API that requires no key.
