We're Cosmic (YC W19), a headless CMS. Today we're launching Team Agents and the Cosmic Agent.

Team Agents are AI-powered team members that live in Slack, WhatsApp, and Telegram. They have names, roles, persistent memory, and real capabilities. Not chatbots. Not one-off prompts. Persistent agents that work alongside your team.

Here's what they can do:

CONTENT AGENTS write blog posts, landing pages, and marketing copy. They generate images, add SEO metadata, and publish directly to the CMS. Message them in Slack, get a finished post back.

CODE AGENTS read your codebase, create branches, write components, and open PRs on GitHub. Need a new page? Message the agent. Review the PR. Merge and deploy.

COMPUTER USE AGENTS browse the web like a human. They log into Vercel Analytics, Google Search Console, Ahrefs, or any web tool. They take screenshots, extract data, and build reports. No API integrations needed. If you can see it in a browser, they can.

TEAM AGENTS tie it all together. They live in your messaging channels with persistent memory. They remember past conversations, learn your preferences, delegate tasks to other agents, and run on a schedule.

How we use it internally:

Every week, 3 Computer Use agents log into our analytics tools in parallel. A content agent synthesizes the data into a report with prioritized action items. Our content agent uses those insights to plan what to write next. Our code agent takes technical action items and ships fixes via PR.

Create content, publish it, measure performance, use the data to decide what to create next. The loop runs itself.

The Cosmic Agent comes built into every project from day one. It manages content, generates images and videos, browses the web, writes code, creates agents, and builds workflows. It doesn't count against agent limits.

Tech details:

- AI models: Claude Sonnet 4.6 / Opus 4.6

- Browser automation: Puppeteer-based computer use

- Channels: Slack, WhatsApp, Telegram, Dashboard

- API: REST

- Workflows: multi-step pipelines with parallel execution

Here's what the full workflow looks like:

  # Create a project with an AI-generated content model
  cosmic projects create
  # → "A recipe blog with recipes, categories, and authors"

  # Generate content
  cosmic content -p "Create 5 recipes with images across different categories"

  # Build a full-stack app wired to your content
  cosmic build -p "A modern recipe blog with search and category filtering"
  # → Generates a Next.js app, pushes to GitHub

  # Deploy
  cosmic deploy start --watch
  # → Deployed to Vercel

  # Later: update the existing codebase with natural language
  cosmic update recipe-blog -p "Add dark mode and a favorites feature" -b feature-branch

  # Create a PR and merge
  cosmic repos pr create 
  cosmic repos pr merge  1
  # → Auto-deploys to production

A few of the more technically interesting pieces:

AI agents. You can create three types: content agents (CMS operations), repository agents (code changes on branches), and computer use agents (browser automation via Puppeteer with AI vision). Chain them into multi-step workflows with scheduling.

Interactive shell. "cosmic shell" drops into a REPL where you navigate workspaces and projects like a filesystem: cd, ls, pwd. System commands with ! prefix. No cosmic prefix needed.

Multi-model. Supports Claude Opus/Sonnet/Haiku, GPT-5/5.2/5-mini/4o, and Gemini 3 Pro. Set a default or specify per-command.

It also handles the day-to-day stuff you'd normally do in a dashboard: billing, team roles, webhooks, domain/DNS config, environment variables.

Built with TypeScript and Commander.js. MIT licensed.

Install: npm install -g @cosmicjs/cli

GitHub: https://github.com/cosmicjs/cli

Docs: https://www.cosmicjs.com/docs/cli

So we built AI Workflows — chain multiple agents together and let them run autonomously, with each step receiving outputs from previous steps.

Three agent types you can chain:

- Code Agents: Build features in GitHub with commits and pull requests.

- Content Agents: Generate CMS content with context injection from previous steps.

- Computer Use Agents: Automate browser workflows and record demos.

How it works:

1. Define steps with agent type, prompt, and configuration

2. Steps run sequentially or in parallel (configurable)

3. Context passes automatically between steps

4. Trigger manually, on a schedule (cron), or via CMS and API events (object.created, object.edited, etc.)

5. Add approval gates for human review before critical steps

Example: Autopilot feature development:

Step 1: Content Agent writes a feature spec based on user feedback

Step 2: Code Agent builds the feature, creates PR, and deploys to production

Step 3: Content Agent generates documentation and a changelog entry

Step 4: Computer Use Agent posts update to team Slack with the PR link and preview URL

Currently in beta. Would love feedback on the workflow model and what use cases you'd want to automate.

I’m Tony Spiro founder of Cosmic (YC W19). Cosmic is a headless content management system (CMS). We provide a web dashboard to create content and API tools to deliver content to any website or app.

We just released Cosmic Intelligence, a suite of AI features to help you optimize product development, content editing, and collaboration using the Cosmic CMS.

With Cosmic Intelligence you can:

- Create AI generated text

- Create AI generated images

- Automatically localize content

- Automatically add image alt text

- Use AI to generate content models

- Use AI for development assistance and API chat

- Get insights into media assets including PDFs and spreadsheets

We built this because we are always looking for ways to improve the content creation and delivery process. Using AI features for automation and chat interfaces, we believe content management workflows can be dramatically improved.

One of my favorite features in this release is the ability to communicate with the Cosmic API using AI. This gives developers an AI pair programmer, helping them build with our API and documentation included for reference. You can also upload an image as a reference, enabling you to get assistance with both the content implementation and frontend design.

Cosmic Intelligence is available on all Cosmic accounts, including our free plan. Read more in the announcement here: https://www.cosmicjs.com/blog/introducing-cosmic-intelligenc.... Let me know what you think in the comments.

Thanks,

Tony

I'm Tony with Cosmic. I built this Cosmic Message App (https://github.com/cosmicjs/cosmic-message-app) to show how to use Next.js, React Server Actions, and Cosmic CMS to build a simple app to add text and upload media to a message feed. All without exposing any API keys to the client.

I found the development process pretty straightforward using Next.js, Cosmic JavaScript SDK, File Upload Block, and React Server Actions.

Overall I'm optimistic about this stack to make building user generated content apps like this, much easier.

Let me know what you think in the comments.

I'm Tony, CEO at Cosmic (YC W19). Today we are releasing Cosmic Pages - free, dedicated web pages to host your Cosmic content. (Read the announcement here: https://www.cosmicjs.com/blog/introducing-cosmic-pages)

With Cosmic Pages, you can host any Object (content item) from the Cosmic CMS on a dedicated public URL, with a single click, no coding required. This enables you to send your content out for review without login or custom coding.

We built this because we have seen teams struggle with using a headless CMS to host their content because of the custom development needed to create and host a webpage to display the content. We thought it would be nice to offer a way for our users to create content and share seamlessly without needing to custom code and host a webpage themselves.

With Cosmic Pages, you can build your content model, create your content, and publish your page to the web in minutes, for free.

Let me know what you think in the comments.

Thanks, Tony

Cosmic is a headless content management system (CMS). We provide a dashboard to create content and API tools to deliver content to any website or app.

Blocks are pre-built website components that you can drop into your project. Choose from landing pages, blogs, image galleries, product pages, and more. With Blocks you can build these features with Cosmic faster than ever.

It's our goal to empower your team to create the best content powered websites and apps. Blocks can be considered the missing "head" to connect with the Cosmic headless CMS. It is our opinionated component frontend for building highly scalable and performant web applications built with tools we think offer a development experience and performance advantage (React Server Components, Next.js, and Tailwind CSS).

React Server Components (RSCs) have unlocked a new paradigm in building data-driven web applications. By safely encapsulating data-fetching inside components, we can use RSCs as building blocks to enable faster and more scalable application development. We are excited for the potential of RSCs and Blocks. This is just the beginning.

To get started, go to the Blocks website (https://blocks.cosmicjs.com/) and follow the steps for installation. View the Blocks demo (Agency Template) (https://cosmic-agency-template.vercel.app/) to see all of the Blocks in action.

Blocks are built to give developers a head start with features that are:

- Performance optimized - Draft preview ready - Mobile responsive - Localization ready - Dark mode ready - Customizable - Accessible - Type safe

Blocks not only provide a fast development experience, they have been optimized for speed and performance by default, so you can ship production-ready faster. Check out the Blocks demo (Agency Template) (https://cosmic-agency-template.vercel.app/) to see how building with Blocks can give you high scores across the board for performance, SEO, and accessibility.

Blocks are open source (https://github.com/cosmicjs/blocks) and built with React Server Components, Next.js, TypeScript, Tailwind CSS, and powered by the Cosmic content management system. You can install Blocks into any new or existing Next.js (v13+) codebase using the Blocks CLI (https://www.npmjs.com/package/@cosmicjs/blocks).

Check it out on the Blocks website (https://blocks.cosmicjs.com/) and let us know what you think in the comments.

I’m Tony, the CEO of Cosmic (https://www.cosmicjs.com), we provide a headless CMS and API toolkit to create and deliver content to websites and apps. Today, we are releasing Cosmic Media which enables you to search millions of high-quality, royalty-free, stock photos, videos, and vectors from popular online media services: Unsplash, Pexels, Giphy, and Pixabay from one convenient interface. It also includes AI-generated images from OpenAI. Check it out here: https://cosmicmedia.vercel.app

We built it to solve our own need to consolidate our existing media extensions, which were individual media extensions using the Unsplash API and Pexels Video API, and we thought, "why not combine them into one"? Rather than search from different stock media websites, seems like it would be nice to aggregate it into one interface. Then we sort of thought about what else might someone want for adding media to their content, so we added DALL-E AI image generation. We've been using it internally and find that it's saved us some time when searching for media to add to our blog posts.

We are offering it as both a stand-alone open source tool and as a Cosmic extension which can be added to your projects for easy access during content creation from the Cosmic dashboard. Check out the code and feel free to customize and extend it to suit your needs: https://github.com/cosmicjs/cosmic-media-extension

There are a lot of free or cheaper CMS options out there with a not great user experience.
