The CMS pricing problem

Every CMS starts cheap. Then the invoice goes up.

Per-seat charges. Per-locale add-ons. Feature-gated tiers. Overage fees in the fine print. Your content stack shouldn't need a spreadsheet to predict next month's bill.

Adapto CMS bundles everything into one flat rate: content API, media CDN, image optimization, localization, webhooks.

How Adapto CMS compares to other headless CMS products
Pricing Other CMS products $99 for webhooks. $99 for i18n. $99 for more contributors. You're at $498/mo for features that should ship by default. Adapto CMS Every feature at every tier. Upgrade for usage, never for capability.
Stack Other CMS products CMS for content. Cloudinary for images. S3 for storage. A CDN for delivery. Four invoices, four things that can break at 2am. Adapto CMS Content API, media CDN, image optimization, all bundled. One dashboard. One key.
Infra Other CMS products Major versions break your plugins. Self-hosting eats engineering hours on staging drift and security patches. Adapto CMS We run the servers, the database, the CDN, the patches. You call the API.
Scale Other CMS products Generous free tier — then you hit 50K records and the price triples. Overages at rates you never saw on the pricing page. Adapto CMS Same features at 500 records as at 750,000. Approach a limit and we email you. No silent overages.

*Compared with Cosmic JS, Sanity, Contentful, Storyblok

I’ve got convinced by the bundled media CDN and the pricing predictability. The most important improvement was a loading speed improvement, from Webflow to the Adapto + Astro client of about 60%. We are using server side generated pages that are rebuilt whenever new content is published on the CMS using a Github action webhook.

I think Adapto can accommodate both early-stage projects and larger applications or web pages.

No add-ons, no feature gates, no surprises

Every CMS primitive a dev team needs. On every plan.

Content modeling, REST API, CLI + AI + Webhooks, Media CDN, localization. The same surface on Free Evaluation as on Professional — the only thing that scales is usage.

CLI & AI

A CLI built for AI agents, not just terminals

Adapto ships a first-class CLI designed to give AI agents — Claude Code, Cursor, or any LLM toolchain — direct, structured access to your content.

Manage collections, trigger builds, and automate publishing from a terminal or from an agent's context. Most CMSs treat agents as an afterthought; Adapto treats them as a primary user.

Claude Code editing content during a build session Cursor scaffolding collections from a spec Agent-driven content migrations Publishing pipelines triggered by LLM workflows
Bundled CDN

One platform. One bill.

CDN, image optimization, webhooks, and content API in one product. No Cloudinary contract.

No separate media host. No glue code. Organize work by organization, invite as many contributors as the project needs, and run unlimited projects under one account.

Agencies managing client rosters Teams with rotating contractors Multi-brand portfolios under one parent org
Asset Library

Centralized asset library across every project

Upload once, reuse everywhere. Manage images, videos, and documents from a single library shared across collections in your project.

Brand asset libraries Multi-site portfolios Cross-project media reuse
i18n Built In

Ship in every language without a pricing penalty

Translate content into as many locales as the project needs without watching the tier requirements creep up.

Other CMSs cap included locales (some cut theirs to five recently) and charge per extra language. i18n is included at every tier — scale languages with usage, not with line items.

Integrations

Webhooks and GitHub Actions that plug into any automation tool

Trigger builds, sync to third-party services, or fire workflows on every content change.

Webhooks and GitHub Actions integrate cleanly with n8n, Make, Zapier, and any HTTP-receiving automation — so content events can rebuild a site, notify Slack, sync to a search index, or kick off a custom pipeline. Included from the free tier, not gated behind a higher tier.

Image Optimization

Image transforms via URL — no pipeline, no build step

Resize, convert, and compress images on the fly by appending URL parameters and the CDN handles it at the edge. No build step. No image pipeline. No separate processing server.

Most setups force you to pre-generate every variant at build time or pay for a third-party transform service; Adapto serves any size, format, or quality from a single source upload.

Collections

Custom collections without unlocking a higher tier

Define exactly the content shapes the project needs — blog posts, products, landing pages, case studies, anything — with custom fields and relationships.

Available from the free plan up, not gated behind a "Pro" tier or sold as an add-on.

A note from the founders

Greetings, we're Vlad and Alex.

Before Adapto, we ran an agency. For years we tried every CMS we could find a reason to recommend. Webflow until a client needed three locales. Cosmic JS until the pricing changed and our smaller clients didn't fit. Sanity for the larger builds, until the per-seat math made onboarding editors a conversation we didn't want to keep having.

Same pattern every time. A reasonable starting price. A feature behind the next tier. A renewal call where the number doubled. A quarterly explanation to the client about why the invoice changed again.

So we stopped looking and built the CMS we wished existed. Flat pricing. Every feature included. Content, media, and image delivery in one product.

Once it was running, migrations went quiet. Client bills stopped surprising anyone. The "what does this cost next year" question finally had a real answer.

We're opening it up because if you've been on the same hamster wheel, you already know the problem.

Step off the wheel. Try it. Let us know what breaks.

Gratefully,

Questions and answers

Pricing, features, limits, migrations, and what happens when your usage grows. If your question isn't here, reach out to us at contact@adaptocms.com

What's the catch with the Free Evaluation tier?
There isn't one. The Free Evaluation tier includes every feature — webhooks, localization, custom roles, media CDN, image optimization and much more. The limits are small on purpose — it's built for evaluation, not production: 500 records, 5,000 API calls, and 2 GB bandwidth per month. When you're ready for production, Hobby starts at $29/mo. No credit card required to evaluate.
Will my price increase after I sign up?
Your plan price is locked for your billing period. If we ever change pricing, existing customers keep their current rate for the remainder of their term. We'll give at least 30 days' notice before any pricing changes take effect, and annual subscribers are protected for their full 12-month period.
Why is Adapto so much cheaper than Contentful or Storyblok?
We don't charge per seat, per locale, or per feature. Those multipliers are what make other platforms expensive — not their infrastructure costs. We also bundle the media CDN instead of selling it as a separate service. Our pricing reflects what the platform actually costs to run, not what the market will tolerate.
Do you have hidden overage fees?
No. If you approach your plan limits, we notify you via email and give you a 7-day grace period to upgrade or reduce usage. We don't silently bill overages, and we don't throttle your API without warning. The price on the plan is the price you pay.
Why don't you have a `Contact Sales` enterprise tier?
Because we publish our prices. The Professional tier at $449/month includes 750,000 records, 1,500,000 API calls, and 1 TB of bandwidth with every feature included. If your scale genuinely exceeds that, reach out — but we'll quote you a published rate, not a number based on your budget.
Do all plans really include every feature?
Yes. Webhooks, localization, custom roles, media CDN, image optimization, asset library, microcopies, custom data structures — all included on every plan, including free. The only difference between plans is usage limits: records, API calls, and bandwidth.
Do you support GraphQL?
Not yet. The API is REST with JSON responses today. GraphQL is on the roadmap and will be offered alongside REST — not as a replacement. For most content delivery use cases, REST with field selection and filtering covers what you need.
Can I use Adapto with my existing frontend framework?
Yes. The API is framework-agnostic. If your framework can make an HTTP request and parse JSON, it works with Adapto. We've seen teams using Astro, Next.js, Nuxt, SvelteKit, Remix, Gatsby, plain HTML, React Native, Flutter, and custom backends. No vendor SDK required — though we provide a TypeScript SDK if you want it.
How does the media CDN work?
Every file you upload is automatically served through our CDN at media.adaptocms.com. Images support URL-based transforms — append ?w=800&format=webp&quality=85 to any image URL for on-the-fly resize, format conversion, and compression. No separate image service, no processing pipeline to manage. Bandwidth is bundled with your plan.
What are Custom Collections?
Custom Collections let you define any data structure beyond the built-in Articles and Pages. Create a Testimonials collection with fields for quote, author, company, and rating. A Team Members collection with name, role, bio, and photo. A Products collection with specs, pricing, and images. You define the fields, the schema, and the relationships. The API handles the rest.
What are Microcopies?
Key-value strings managed in the CMS — button labels, error messages, form placeholders, tooltips. Fetch a single microcopy by key or pull the entire dictionary for a language. This means your content team can update UI text without a developer touching code or triggering a deploy.
Can I migrate from Contentful / Storyblok / Strapi / Sanity?
Yes. Content in Adapto is structured JSON accessible via REST API. You can write a migration script that reads from your current CMS API and writes to Adapto's API. We're also building dedicated migration guides for the major platforms. If you need help, reach out — we'll walk you through it.
What happens to my data if I leave Adapto?
Your content is yours. You can export everything via the API at any time — pages, articles, custom collections, media assets. If you cancel your account, we keep your data accessible for 30 days to allow full export. After 30 days, it's permanently deleted. No hostage data.
