Panel generated from the schema
Every page, content type and declared field becomes an editing screen. The client sees only what the site actually has: no leftover menus, no settings screens.
site.json → /admin
Features
Everything in the box
A complete CMS in the download: panel, rich fields, SEO, forms, members and multi-language. No plugins to hunt, no paid tier.
The essentials
A panel that builds itself
The admin is generated from the site.json — and it is born with what every site needs underneath.
Built-in SEO
Meta title, description and og:image attached automatically to every page and item, with a generated sitemap.xml — including hreflang when the site is multi-language.
sitemap.xml · hreflang · og:image
Media library
Upload with alt text, clean file names and named sizes generated on demand: thumb, hero, whichever ones you declare.
jpeg · png · gif · webp · svg · pdf
Forms out of the box
CSRF and honeypot protection, submissions saved to the database and emailed with a dynamic subject. Email failed? The submission is still stored.
CSRF · honeypot · assunto {{name}}
Members area
Site logins (clients, students, leads) with their own types and fields, customizable routes and sessions kept apart from admin users. Trouble on one side never reaches the other.
sessions isolated from the admin
Multi-language, natively
Prefixed URLs and a slug per language, per-record translation in tabs inside the editor itself, and automatic fallback: the theme helpers resolve the language on their own.
/pt/ · /en/ · /es/
Fields
17 field types
Declared in site.json, rendered in the panel, read in the theme with field().
- text
- Single-line text — titles, names, headlines.
- textarea
- Long text without formatting.
- richtext
- Visual editor (TipTap) that saves clean HTML.
- image
- One image from the media library; resolved with image_url().
- gallery
- Ordered list of images.
- select
- Dropdown with options you define.
- boolean
- On/off — highlight, badge, optional section.
- number
- Numeric value.
- Email input with HTML5 validation.
- url
- URL input with HTML5 validation.
- date
- Date picker.
- repeater
- A group of subfields that repeats — testimonials, FAQs, lists.
- flexible
- Blocks with named layouts — the ACF "flexible content".
- link
- Title + URL + new tab; printed with link_tag().
- item
- Relationship to other content, via search — published items only.
- group
- Collapsible organizational box in the admin; storage stays flat.
- tabs
- Organizational tabs in the editor — visual only, no data change.
Structure
Declared structure, free content
The site.json describes what the site can hold. The panel and the URLs follow.
Content types
Posts, cases, services, listings: you name them. Each type has a slug, a template, an archive listing and, if you want, alternate templates per item.
Taxonomias
Categories, tags and whatever else you need: hierarchical or not, with an optional page of their own and custom fields on the terms.
Relacionamentos
O campo item links content together — the case to the service, the post to the author — with a search combobox in the panel.
Pages, both ways
Structural pages declared in the schema (home, contact) and page templates so the client can create new ones in the admin, each with its own fields.
Global options
Phone, social links, footer copy: option pages become forms in the admin and come out in the theme with option('contato.phone'), cached, a single query.
Reusable groups
field_groups defines field bundles once (local SEO, a CTA block) and reuses them across pages and types in a single line.
Vibe coding
The CLI is the API
Everything the panel does, the bin/velk does over JSON. That is how an AI agent creates the schema, writes content, publishes and maintains the whole site, end to end.
- bin/velk

- page:sync

- item:update
- page:update
- item:schema

Under the hood
Built to last in production
-
Upgrades without fear
The engine is a versioned dependency: the upgrade downloads the tarball, verifies the sha256 and swaps only the core files. Theme, content, uploads and
.envstay untouched. -
Auto-migrate on boot
Uploaded new files over FTP? On the first request Velk applies the pending migrations by itself, serialized with a MySQL lock: a host without SSH finishes the upgrade with no terminal at all.
-
Secure out of the box
Output escaping with
e(), SQL 100% on prepared statements, CSRF on every POST, honeypot on forms and member sessions isolated from the admin ones.
