Licensing & pricing
Community — MIT, complete
Everything in packages/ is MIT: the full editor, dual mode, tables with
merging, all plugins, all ten languages, the tui.editor compat layer. It is
not a demo, not feature-gated, and it never will be — the boundary below is
fixed and public (CONTRIBUTING.md).
Pro — source-available, flat price, offline license

What “no meters” means, concretely. TipTap Business is $1,199/month with document limits; CKEditor’s collaboration add-on is $299/month and counts “editor loads”. Inkroom Pro has no counters to hit: unlimited documents, unlimited editors, unlimited loads, one flat invoice.
How the license works. Your key is a JSON payload signed with Ed25519,
verified locally in ~1ms. No activation server, no phone-home, works
air-gapped. validUntil gates which releases you can update to — the
Sublime model: every version released inside your window runs forever,
renewals are for updates, not for permission to keep working. And by policy
and code: an expired or missing license logs one console notice and never
degrades your production app. Enforcement is the EULA,
not sabotage — we sell software, not hostages.
import { registerLicense } from "@inkroom-pro/license";await registerLicense(process.env.INKROOM_LICENSE);Source-available. Paid customers get the pro/ source — audit it, step
through it, patch it locally. The license verification code itself is public
in this repo so the “no phone-home” claim is checkable, not marketing.
FAQ
Why not AGPL dual-licensing for Pro? We evaluated it (BlockNote proves it works). Enterprise legal review of AGPL is a real sales tax measured in weeks; a plain commercial license with public source is faster for the people actually paying. The MIT core is unaffected either way.
Does the free editor stay maintained if Pro fails? The MIT packages are self-contained and forkable — that’s the point of MIT. But the plan is the reverse: Pro revenue is what funds the free editor’s maintenance.
