CompletelyHeadless

Headless CMS

A headless CMS for teams that ship content, not tickets.

Model your content once, translate it, structure it into pages, and serve it anywhere through a clean REST API. Organizations, projects and per-project access are built in from day one.

CompletelyHeadless content editor with entries, languages and a content type schema

Everything the editors and the developers need

Schemas & fields

Text, rich text, numbers with min/max, date and time, links, media, single entry references, lists and auto-sorted latest lists — all reordered by drag and drop.

Shared type library

Link a content type across projects and edit it once, or duplicate it and go your own way.

Schema inheritance

Mark a type inheritable and compose it into others live.

Multilingual entries

A language catalog per organization, selected languages per project, and translatable fields per schema.

Content tree

Set a root page and build the site hierarchy by dragging pages into place.

Drafts & version history

Every save is a version. Publish, unpublish, restore — with a per-organization limit on how much history is kept.

Media library

Global and per-project folders, drag-and-drop moving that never breaks references, automatic hero (WebP), card and thumbnail renditions at widths you choose, focal point and alt text.

REST API & OpenAPI

Public read endpoints for project info, entries, single pages, the page tree and media — with full recursive expansion, language selection and a generated OpenAPI 3.1 spec.

API keys & rate limits

Hashed keys with expiry, revocation, one-click rotation with a grace period, per-minute rate limits and audit logs.

Built for speed

A one-hour response cache per project, cleared automatically the moment content, schema, media or languages change.

Teams & access

Owners, admins and editors, with access granted per project.

AI-assisted import

Describe an existing site and get schemas and entries created for you.
