Cosmic Review (2026): Pricing, Features & Honest Verdict

Cosmic is a headless CMS that now runs AI agents against your content. Its pricing page is the most detailed we have read, and that detail is what exposes the flaw: the Team plan Cosmic marks “Most Popular” is the worst value in the ladder. Best for: small teams shipping content-driven apps. Price: From $49/mo (free plan: yes). Rating: 7.5/10

What is Cosmic?

Cosmic is a headless content management service. You model content in a web dashboard, then pull it into any front end over a REST API, an SDK, a CLI or an MCP server. The company was started by Tony Spiro and Carson Gibbons out of an agency job in 2014, shipped its first version in 2016, and went through Y Combinator in the Winter 2019 batch. It is based in San Francisco and the team is small.

What changed recently is that Cosmic stopped being only a CMS. The platform now runs AI agents that sit in your Slack, WhatsApp and Telegram channels, write and publish CMS content on their own, open pull requests against your GitHub repositories, and automate a browser. The Product Hunt launch that brought us here was Agent Plugins, which connects those agents to outside services through vendor-official MCP servers. That is a big swing for a company this size, and the pricing has grown a lot of moving parts to match.

What Are Cosmic’s Key Features?

Agents that live where your team already talks

A Cosmic agent joins a Slack workspace, a WhatsApp group or a Telegram channel as a conversational member. You give it a name, a role, a personality and a goal, and it can work toward that goal on a schedule or on demand. The same agent can read and write CMS content, build and deploy applications, hand work to other agents, and call external APIs. Agents and workflows are separate pools, and only active agents count against your plan limit, which is a sane way to meter it.

Agent Plugins connect agents to real services

Each plugin is a remote MCP server, a set of skills, and a slot for that vendor’s credentials. The launch shipped GitHub, Linear, Stripe, Cloudflare, Render, PostHog, Resend, Netlify and Sentry. You install a plugin on one specific agent rather than across the whole account, so the agent that owns your deploys gets Cloudflare and Render, and the agent that owns billing gets Stripe. Holding credentials per agent instead of per account is the right call and not every competitor does it.

Buckets, objects and object types

The content model is three layers: a bucket holds object types, an object type defines a shape, and objects are the content itself. The counts are what your bill turns on. Free gives you 1 bucket and 1,000 objects. Builder gives 2 buckets and 5,000 objects. Team gives 3 and 20,000. Business gives 5 and 50,000. If you outgrow the object count you can buy packs of 10,000 for $10 a month, and each pack adds 25 object types too.

Cosmic Insights, included on every plan

Insights is cookieless web analytics with per-object attribution, and Cosmic includes it everywhere, including the free tier. Free gets 100,000 events a month with 30-day retention, Builder 1 million at 90 days, Team 10 million at 365 days, Business 100 million at 365 days. Overage is $10 per additional 1 million events. Per-object attribution is the interesting part: you can see which specific content object drove a session, which is hard to get out of a general-purpose analytics tool.

How Much Does Cosmic Cost?

Cosmic starts at $49 a month for Builder, with a free forever tier below it and a 10% discount for yearly billing. The ladder runs Free at $0, Builder at $49, Team at $299, Business at $499, and Enterprise at a custom annual price. No credit card is needed to start.

The plan price is not the whole bill. Four features that most people would call table stakes are sold as add-ons at $99 a month each: Webhooks, Localization, Revision History and Automatic Backups. A bundle of all four is $199 a month, and every add-on comes with a 14-day free trial. That pricing holds on every self-serve plan, so a Business customer paying $499 a month still pays $99 to receive a webhook, or $698 a month all in. Sanity includes webhooks on its free tier. Strapi includes them in the self-hosted core. This is the single most aggressive thing on Cosmic’s pricing page.

Seats and buckets are metered too, at $29 per additional user per month and $29 per additional bucket per month. Overages are published in full and the rates are low: $0.23 per 10,000 non-cached API requests, $0.023 per 10,000 cached, $0.36 per GB of API bandwidth, $3 per 1,000 media files, $0.069 per GB of media storage, $0.30 per GB of media bandwidth. Publishing an overage rate card at all puts Cosmic ahead of most of the category.

Why Is Cosmic’s Most Popular Plan Its Worst Value?

Do the division and the ladder inverts in the middle. Cost per 1,000 objects: Builder is $9.80, Team is $14.95, Business is $9.98. Cost per team member: Builder $16.33, Team $59.80, Business $49.90. Cost per agent: Builder $16.33, Team $29.90, Business $19.96. On all three meters, Team is the most expensive tier in the lineup. It is also the one carrying the “Most Popular” badge.

The gap is large enough to route around. Builder at $49 plus two extra seats at $29 each plus two object packs at $10 each comes to $127 a month, and it gets you 5 team members and 25,000 objects. Team costs $299 for 5 members and 20,000 objects. You give up buckets (2 versus 3), agents (3 versus 10), API bandwidth (10 GB versus 100 GB) and chat support. If your bottleneck is seats and content volume rather than agent count, Builder plus add-ons beats Team by $172 a month and gives you more objects.

One more thing the comparison table quietly says: Projects are capped at 1 on Free, Builder, Team and Business alike. Only Enterprise gets a custom project count. A company paying $499 a month is still running a single project. Buckets give you some separation inside it, but if you expected a $499 plan to host a second product, it does not.

What Do Cosmic’s AI Tokens Actually Cost?

Cosmic sells AI capacity two different ways and never reconciles them. Token add-ons are priced by direction: Input Tokens at $5 per million per month, Output Tokens at $19 per million per month. Token Packs are universal, work with any model, and cover both input and output: 2 million for $25 ($12.50 per million), 10 million for $110 ($11 per million), 50 million for $475 ($9.50 per million). The 50M pack wears a “Best Value” label.

It is only the best value for some workloads. If your usage is output-heavy, the 50M pack at $9.50 per million costs exactly half the $19 output add-on, and that is a real saving. If your usage is input-heavy, which describes most retrieval and content-grounding work, the same “Best Value” pack costs 90% more than the $5 input add-on. A team that reads the badge and buys the big pack for a RAG-style workload nearly doubles its token bill. Cosmic gives no guidance on which to pick, and the correct answer is usually a mix of both.

Credit where it is due on one adjacent point: semantic search embedding is free and you only pay when a query runs. That is the customer-friendly way to price it, and plenty of vendors charge for both sides.

Who Is Cosmic Best For?

Use Cosmic if you are a small team building a content-driven app on Next.js, Astro, Nuxt or Svelte, you want the CMS and the automation in one bill, and you can live inside one project. The Builder tier at $49 with a couple of add-ons is a strong deal, and the free tier is real enough to build a prototype on rather than a demo.

Use Cosmic if you actually want the agents. The agent layer is the reason to pick it over a plain headless CMS, and the plugin model is well designed. If you are only going to use it as a content API, you are paying for a lot of surface you will not touch.

Skip Cosmic if you need webhooks or revision history and you are price sensitive, because $99 a month each is a lot for features other vendors include. Skip it if you run more than one product, since every self-serve plan is capped at a single project. And skip it if you need SSO or an uptime SLA, both of which are Enterprise-only.

Best Cosmic Alternatives

Sanity is the closest fight. Free forever covers up to 20 user seats, 2 permission roles and 2 public datasets, which is a much more generous free tier than Cosmic’s 2 seats. Growth is $15 per seat per month up to 50 seats. Sanity charges per seat where Cosmic charges per plan, so Cosmic wins on a big team and Sanity wins on a small one. Sanity’s add-ons are pricier at the top: dedicated support is $799 a month and an extra dataset is $999 a month.

Strapi is the answer if you want to own the box. The core is open source and self-hosted for nothing. Strapi Cloud runs $35 per project per month for Starter with 100k API requests, $90 for Pro with 1M requests, and $450 for Business with 10M requests, plus $60 per extra environment. Strapi prices per project, which is the opposite of Cosmic’s one-project cap, so multi-product teams should look here first.

Contentful is the enterprise default and the one most Cosmic prospects are escaping. It has a free tier and moves quickly to a quote. We could not confirm its current paid figures from Contentful’s own site during this review, so treat any number you read elsewhere with care. What is clear is the shape: Contentful sells to procurement, Cosmic sells to a developer with a credit card.

Final Verdict: Is Cosmic Worth It?

Cosmic is a good product with a pricing page that rewards reading carefully. The agent layer is real, the plugin model is thoughtfully built, the overage rate card is published in full, and the free tier is usable. For a small team on Builder, this is one of the better deals in headless CMS, and the $49 tier is where we would start almost everybody.

The reservations are all about the middle and the add-ons. Team at $299 is the worst value per object, per seat and per agent, and it is the tier Cosmic points you at. Four ordinary features cost $99 a month each on top of any plan. Every self-serve tier is stuck at one project. And the two ways to buy AI tokens can differ by 90% for the same work with no guidance on which to choose. Buy Builder, add the seats and object packs you need, and skip the Team plan unless you specifically need ten agents. Do that and Cosmic is worth it.
