This is a hypertext prototype of the System Reference Document 5.1 (the 2014 fifth-edition rules), built in the spirit of Old Gus' Daggerheart SRD: one static site, no accounts, no ads, works offline.
Pick a category on the left, search, and click an entry. Monsters can be sent straight into the Encounter calculator; conditions are cross-linked from monster stat blocks.
Everything is derived live from the six ability scores. Your character is saved in this browser only (localStorage) and can be exported as JSON.
2014 XP-budget method, plus the Lazy DM deadly benchmark (Sly Flourish): an encounter may be deadly if the monsters' total CR exceeds ¼ of the party's total levels — or ½ if everyone is below 5th level. Add monsters from the Compendium, or enter CRs by hand.

A vertical slice toward “Old Gus' Daggerheart SRD, but for 5e”: compendium + character calculator + encounter calculator, as a fully static site. Put the folder on any static host (or open it locally) and it works offline — a service worker caches the app shell and data after the first visit over http(s).
