Cosmic — Developer Tools

Cosmic is an AI-powered headless CMS that lets teams build, ship, and scale faster. It decouples the backend from the frontend, so you can use any framework — React, Vue, or others — and manage content through a visual dashboard. What sets Cosmic apart is its native AI agents that live in Slack, WhatsApp, and Telegram, helping to create content, build features, fix bugs, and automate workflows.

What it does

You define content models (objects, fields, relationships) in the Cosmic dashboard. Content is served via REST or GraphQL API to any frontend. Editors use a drag-and-drop interface to create and update content without touching code. AI agents can draft blog posts, generate code with pull requests, triage bugs, and automate standups or deployments.

Who it is for

Best for developers building Jamstack or static sites, marketing teams managing multi-language content, and agencies delivering client projects. Not ideal for non-technical teams who want a fully hosted website with no developer involvement.

Use cases

• Publishing blog posts with AI-assisted drafting and SEO metadata
• Building feature pages with custom content models and localization
• Automating content updates from team chat (Slack, WhatsApp, Telegram)
• Creating and deploying full projects via the Cosmic CLI

• Content modeling — Define custom object types, fields, and relationships
• REST & GraphQL APIs — Fetch content with any frontend framework
• Media manager — Upload, optimize, and serve images with CDN
• Localization — Manage content in multiple languages from one dashboard
• Team agents — AI assistants in Slack, WhatsApp, and Telegram that create content, build features, and fix bugs
• Webhooks — Trigger builds or sync content to external services
• Role-based access — Control who can edit, publish, or manage settings
