The Prismic Alternative Built for AI

Prismic's recent pricing changes and slice-based architecture are pushing developers to look elsewhere. Cosmic gives you a fully managed, AI-native headless CMS with flexible content modeling, a clean REST API, and agents that automate your content operations.

Why Developers Are Leaving Prismic

Prismic has been a solid choice for developer teams for years. But three things have changed:

Pricing changes hit without warning. Prismic restructured their pricing, and many teams found themselves paying significantly more for the same usage. For startups and growing teams, unpredictable pricing is a dealbreaker.

Slice Machine locks your content model into your codebase. Slice Machine is clever, but it comes with a fundamental trade-off: your content model lives in JSON files version-controlled alongside your frontend. Add a new field? Run the CLI, push a type definition, deploy your frontend. Editors cannot change the content structure without a code deployment. That is a developer bottleneck masquerading as a feature.

No native AI agents. Prismic lists AI features as "beta, available upon request." In 2026, your CMS should have AI built in, not gated behind a waitlist.

Cosmic solves all three.

What Makes Cosmic Different

REST API Built for Speed

Cosmic's REST API delivers structured JSON with sub-100ms response times. No proprietary query language to learn. No SDK-specific setup per framework. Fetch your content from any environment that can make an HTTP request:


That same call works in Next.js, Nuxt, Astro, Remix, Vue, Svelte, or any Node.js environment. No adapter required.

Content Models That Live in the CMS, Not in Your Code

With Prismic Slice Machine, your content schema lives in JSON files inside your repository. Every schema change is a developer task: update the config, run the CLI, push the type, deploy.

With Cosmic, your Object Types live in the dashboard. Add a metafield, and it is immediately available in the API. No CLI command. No deployment. Your editors can request a new field and have it in production in five minutes.

AI Agents Built Into the Platform

Cosmic ships with four types of AI Agents on every project:

Content Agents research topics, write drafts, generate featured images, optimize for SEO, and publish to your CMS on a schedule. Set one up in minutes. Come back to polished content.

Code Agents connect to your GitHub repository. They read your codebase, create branches, commit changes, and open pull requests. Your CMS can ship code.

Computer Use Agents browse the web autonomously. Use them for competitive research, automated QA testing, or monitoring your live site.

Team Agents join your Slack, WhatsApp, or Telegram. Your team manages content from the tools they already live in.

Prismic has no equivalent to any of this.

Flexible Pricing That Scales With You

Cosmic plans are flat-rate with multiple Buckets (projects) included. Prismic charges per repository, so costs multiply as you add projects.

PlanCosmicPrismic (approx.)
Free$0/month, 1 Bucket, 1,000 Objects$0, 1 repo, 1 user
Entry paid$49/month (Builder), 2 Buckets~$10-25/month per repo
Team$299/month, 3 Buckets, 5 members~$150/month per repo
Business$499/month, 5 Buckets, 10 members~$675/month per repo

A team running three projects pays one Cosmic Business plan. On Prismic, that could mean three separate repository subscriptions.


Real Teams. Real Results.

"Cosmic is: us never having to ask a developer to change anything on the backend of our website."

Maximilian Wuhr, Co-Founder at FINN

FINN, the car subscription platform, uses Cosmic to give their content team full autonomy over the website. Editors update content, launch campaigns, and manage the site without filing a single ticket to engineering.

Other teams running Cosmic in production include Parque Explora, Plato, Vuetify, and Tripwire Interactive.


Works With Every Framework Your Team Uses

Cosmic's REST API and TypeScript SDK work with any JavaScript framework or server-side language:

Next.js | React | Vue | Nuxt | Astro | Remix | Svelte | Gatsby

Unlike Prismic's Slice Machine, which is purpose-built for Next.js and Nuxt, Cosmic works cleanly across your entire stack. Deliver the same content to your website, your mobile app, your email templates, and any other channel from a single API.
