What to look for in a headless CMS with an API and CLI
Content modeling, authentication, and a publishing workflow an agent can run on a schedule, not just a human at a keyboard.
Headless CMS
A headless CMS stores and manages content separately from how it's displayed, exposing it through an API instead of a built-in template layer. You fetch it with JavaScript, a static site, or a script and render it anywhere. Floggy adds a CLI and SDK so an agent can publish without a browser.
Running the CLI from a script or an agent
Authenticate
Store an API token as an environment variable so the CLI or SDK can authenticate without a person typing a password. This is what makes the rest of the flow runnable from a script, a cron job, or an agent instead of a browser session.
Create or update an entry
Call the CLI to create a new entry or update an existing one: set the title, body, slug, and any custom fields. An agent can generate the body text and pass it straight into this step, the same way a person would fill out a form in an edito
Publish
Flip the entry's status from draft to published, either as a separate command or as a flag on the create step. Keeping this as its own step lets you review or hold content before it goes live, even in an automated pipeline.
Schedule or repeat
Run the same sequence on a schedule, a cron job, a CI pipeline, or an agent that decides when to act, so new content or updates go out on a recurring cadence instead of a one-off run.
Custom collections for structured content beyond blog posts
Product or listing catalogs
Define a collection with fields that match a catalog, price, category, availability, instead of forcing a product into a blog post schema. Each entry is still reachable through the same API and CLI.
Programmatic SEO pages
Structured collections are what make programmatic SEO practical: define one schema once, then generate many entries against it (city pages, comparison pages, glossary terms) through the API instead of
Structured data sets
Anything with a repeatable shape, FAQs, changelog entries, team bios, case studies, fits a custom collection better than a generic blog post field set, and stays queryable through the same API.
Headless CMS vs. a plain REST API you build yourself
| Feature | FloggyRecommended | DIY REST API |
|---|---|---|
| Content modeling | Collections and fields defined for you, editable without touchin | You design and maintain the schema, database, and validation you |
| Editor for humans | A real editor UI ships alongside the API, so a person can write | Nothing to write in unless you also build an admin UI |
| Agent and CLI support | CLI and SDK built for scripted or agent-driven authoring and sch | You write and maintain your own client and authentication layer |
| Publishing workflow | Draft and published states, and versioning handled by the platfo | You build draft states, publish logic, and any versioning yourse |
| Structured collections beyond posts | Custom collections for catalogs, programmatic SEO pages, and str | Possible, but every collection type is custom code you write and |
Common questions
How does a headless CMS work?
Content is stored in the CMS and exposed through an API as structured data (usually JSON). A separate front end, a site, an app, or a script, fetches that data and renders it. There's no built-in template layer connecting the content directly to a page, which is what makes it headless.
Is it common to use a headless CMS instead of a standard REST API?
Yes, and the framing is a bit misleading: a headless CMS is usually built on top of a REST (or GraphQL) API, not an alternative to one. The choice is really between building your own API and content storage from scratch versus using a CMS that already handles content modeling, an editor, and a publishing workflow, and exposes it all through an API for you.
Can an AI agent publish through the API without a person involved?
Yes, if the CMS provides a CLI or SDK with token-based authentication, an agent can create, update, and publish entries the same way a script would, without a browser session. That's the setup Floggy is built around.
Do I need custom collections if I'm only publishing blog posts?
No. Blog posts work fine in a default collection. Custom collections matter once you need structured content that doesn't fit a post schema, like a product catalog or a set of programmatic SEO pages.
