Building a brand guideline after the identity is done is hours of mechanical work: the lockups, the one-colour versions, the clearspace page, the contrast table, the “do not do this” page, and then four hundred files named consistently enough to hand over. All of it follows rules. So it should be automatic.
Keyline makes no brand decisions. It executes, extends and documents yours. Where something has to be chosen — which logo version is allowed on which background, what a favicon falls back to — the answer is computed and the reasoning is printed next to it. Nothing is a matter of taste that you did not set.
What it makes
| Lockups | Every arrangement in every colourway, as components, so instances you place elsewhere survive a regeneration. |
|---|---|
| Colour | Tonal ramps in Oklab, a WCAG contrast matrix, which logo version each background permits, and the palette in six code formats. |
| Type | A scale bound to real text styles, in six code formats. A second scale for a second script, because Persian and Latin faces are not the same size at the same number. |
| Rules | Clearspace measured from your artwork, minimum sizes per medium, and which arrangement to use where. |
| Misuse | Eleven violations made from your own logo — three of them measured against your own settings, so the page stays true when you change them. |
| Icons | Favicons in the set browsers actually ask for, and a profile picture that survives a round crop. |
| The bundle | Three to four hundred files: SVG, PNG at three scales, PDF, split by language and colourway, with the rules written out in a README. |
Nothing leaves your machine
No artwork, no colours, no fonts, no file contents, and no telemetry of any kind. Keyline's manifest permits exactly one network destination — the licence check — and Figma enforces that, so it is something you can verify rather than something we ask you to believe.
Pricing
The plugin is free to install, and the free tier is a real one: lockups, the palette, the type scale and the document. What a subscription adds is the pages that set out rules, and the export.
$99 / year
Pro — one Figma account, any number of computers.
$249 / year
Studio — five Figma accounts.
$49 / year, kept for good
Founding 100 — the first hundred subscribers keep this price for as long as they keep the subscription.
Everything, once, free. Each Figma account gets one run with all ten pages and a full export, so you can see the whole thing on your own brand before deciding anything.
Prices are in US dollars. Tax is added at checkout where it applies.
If you stop paying
Nothing you have made is touched. Your settings, your logo slots and every page you have generated stay where they are. What pauses is generating the paid pages and running new exports — and everything you already exported is yours, with no restriction, including for client work you charge for.
