Cosmic vs. Directus

Directus vs Cosmic: database platform vs AI-native CMS

Directus and Cosmic both expose content over APIs. They are built for different jobs.

Directus is a data platform. It introspects a SQL database and gives you an admin app, REST, GraphQL, and WebSockets on top of those tables. If you already have Postgres and you want a UI and API on it without migrating data into a CMS, Directus is purpose-built for that.

Cosmic is a headless CMS. Objects, Object Types, and metafields live in Cosmic. You query them with a REST API and TypeScript SDK. Media, CDN, and AI agents are part of the product. You do not provision a database.

When Directus is the right tool

Pick Directus when the database is the source of truth:

• You need to wrap an existing production SQL schema without copying it into another system.
• Teams besides marketing (ops, internal tools, data) should edit the same tables.
• GraphQL and realtime WebSockets are requirements, not nice-to-haves.
• You must run the stack in your VPC for compliance.

If those are hard requirements, Directus is the better fit. Cosmic will not sit on your Postgres instance.

When Cosmic is the right tool

Pick Cosmic when content is the source of truth:

• Marketing and editorial teams need a CMS, not a database admin.
• You want AI agents that write content, open PRs, and run in Slack.
• You do not want to operate SQL, Directus upgrades, or extension compatibility.
• The frontend is Next.js, Astro, or similar and should consume a hosted content API.

AI: agents on the CMS vs Flows on the database

Directus Flows are real automation: events on collections can trigger operations, webhooks, and scripts. That is workflow on your data layer.

Cosmic agents are a different layer:

Content Agents create and edit CMS objects, including on a schedule.

Code Agents connect to GitHub and open pull requests.

Computer Use Agents browse the web for research, QA, and monitoring.

Team Agents join Slack, WhatsApp, and Telegram.

Multi-agent workflows chain those together. The MCP server connects Cursor and Claude to the same bucket.

Developer experience

Directus: provision or connect SQL, run Directus (Docker is common), model collections in the admin or via schema, query REST or GraphQL. Extensions and Flows live next to the database. Excellent when data already exists.

Cosmic: create a Bucket, define Object Types, query with @cosmicjs/sdk. No SQL, no Docker, no migrations. Agents and MCP can create types and objects from the tools your team already uses.

import { createBucketClient } from '@cosmicjs/sdk'

const cosmic = createBucketClient({
  bucketSlug: 'your-bucket-slug',
  readKey: 'your-read-key',
})

const { objects: posts } = await cosmic.objects
  .find({ type: 'posts' })
  .props(['title', 'slug', 'metadata'])
  .depth(1)

Pricing

Cosmic

No credit card on Free. Additional team members are $29/user/month. Full pricing.

Directus

The open-source core is free to self-host. Budget for compute, PostgreSQL (or another supported database), file storage, and the time to upgrade Directus and extensions. Directus Cloud sells hosted projects with a limited free Community option and paid tiers. Use Directus's current pricing page for Cloud numbers; they are not Cosmic's to quote as a substitute for a self-host bill.

Why teams choose Cosmic over Directus

No database to run. Cosmic is a content API. Directus is a layer on SQL. If you do not already have (or want) that database, Cosmic is less to operate.

AI agents are built in. Directus Flows automate data operations. Cosmic agents create content, write code, and work in chat. See Cosmic AI.

Media and CDN included. imgix transformations plus AI image and video generation.

MCP-native. Connect the tools you already use to the CMS without standing up Directus plus a custom MCP wrapper.

Why teams choose Directus over Cosmic

Your SQL database stays the source of truth. Directus introspects it. Cosmic will not wrap Postgres.

GraphQL and realtime. First-class in Directus. Cosmic is REST-only.

Open source and self-hosted. Audit the code, run it in your VPC, keep the data on your terms.
