Finding the best free headless CMS for a Next.js project in 2026 is harder than it looks. Every vendor buries the real limits — API call caps, seat restrictions, bandwidth ceilings — in a pricing footnote. This post cuts through that: five CMS options, free tier only, honest about what breaks first.
What free actually means across these five CMS options
Before the comparison: there are two categories of "free" here. Managed SaaS free tiers (Sanity, Contentful, Storyblok) give you a hosted service with hard caps. Self-hosted open source (Payload, Strapi) are free in licence cost but you pay for the server, Postgres, backups, and your own time. Neither is bad — they suit different project shapes.
Sanity free tier (2026)
Sanity's free plan is called the Free plan. At the time of writing (check sanity.io/pricing for current numbers) the headline quotas are: 20 users, 2 public datasets, 10k documents, 1M API CDN requests/month, 250k (non-CDN) API requests/month, 100 GB assets, and 100 GB bandwidth/month.
What you keep on free: the full GROQ API, Sanity Studio (embeddable in your Next.js App Router at /studio), image transforms via the CDN, and the TypeGen pipeline. Presentation / visual editing also works on free.
What you lose: no private datasets (public datasets can be read without a token), only 2 roles, no content releases, and no overages — the quotas are hard caps, so you can't pay to go past them.
When you outgrow it: the hard caps are the trip-wire — documents, requests, or bandwidth, whichever you hit first. The Growth plan at $15/seat/month adds private datasets, more roles, and pay-as-you-go overages instead of a hard stop. For a side project or staging environment Sanity free is excellent. For a live marketing site with a real content team, budget for Growth from day one.
// This GROQ query works identically on the free tier — no feature gates on query language
*[_type == "post" && defined(slug.current)] | order(publishedAt desc) [0..9] {
_id,
title,
"slug": slug.current,
"lqip": mainImage.asset->metadata.lqip,
publishedAt
}
Contentful free tier (2026)
Contentful's Free plan (at the time of writing — check contentful.com/pricing): 10 users, 100K API calls/month, and 50 GB CDN bandwidth/month, enforced as hard caps rather than billed overages. Contentful's usage-limit docs also say the Free plan is for testing and learning the product, not commercial production use.
What you lose on free: the higher-tier features (Workflows, Launches, advanced roles) and, more importantly, the right to run a commercial production site on it. ISR revalidation and preview traffic count against the 100K call cap faster than you'd expect on a busy Next.js app.
It still works fine for a single-developer prototype or agency proof-of-concept. Ten seats is reasonable.
When you outgrow it: the moment the project goes live commercially. The Lite plan is listed at $300/month. That jump is steep and it's the main reason Contentful loses clients at the "we're ready to go live" stage.
Storyblok free tier (2026)
Storyblok Starter (free, at the time of writing — check storyblok.com/pricing): 1 space, 1 user (max 2), 100,000 API requests/month, 100 GB traffic/month, 2,000 assets.
100k API requests per month is workable but tighter than it sounds. A Next.js page using ISR with a 60-second revalidation window can make up to 43,200 calls per month on its own, so a site with a handful of frequently-visited pages plus editor previews can get there. Use longer revalidation windows or on-demand revalidation via webhooks.
Storyblok's Visual Editor is its differentiator and it is included on Starter. The real limit is seats: one user (two max) means free is for a solo developer, not a content team.
When you outgrow it: as soon as more than one or two people need to edit. The Growth plan is $99/month (monthly billing). Worth it if you need visual editing; otherwise look elsewhere at this price point.
Strapi community (self-hosted open source)
Strapi's Community edition is MIT-licensed, runs on Node.js, and costs nothing in licence fees. You pay for hosting: a DigitalOcean droplet ($6–$12/month), a managed Postgres instance ($15–25/month on Railway or Render), and your time.
What you get: REST and GraphQL APIs, a decent admin panel, role-based access control (basic), plugins ecosystem, and full schema control via TypeScript files. The Strapi v5 release in late 2024 improved the TypeScript support considerably.
What you lose vs cloud CMS: no built-in asset CDN (you wire S3 + Cloudfront yourself), no managed backups by default, and upgrades are your responsibility. The plugin ecosystem has fragmentation — some plugins are stuck on v4 schemas.
For a Next.js project: Strapi works well if you or your client already has a server/infra budget and you want SQL-backed content with complex relational schemas. The REST API is straightforward to consume with fetch in Next.js RSC.
// app/posts/page.tsx — consuming Strapi REST in RSC
import type { StrapiListResponse, Post } from "@/types/strapi";
export const revalidate = 60;
export default async function PostsPage() {
const res = await fetch(
`${process.env.STRAPI_URL}/api/posts?populate=coverImage&sort=publishedAt:desc`,
{ headers: { Authorization: `Bearer ${process.env.STRAPI_TOKEN}` }, next: { revalidate: 60 } }
);
const { data }: StrapiListResponse<Post> = await res.json();
return <ul>{data.map(p => <li key={p.documentId}>{p.title}</li>)}</ul>;
}
Payload CMS (open source, self-hosted)
Payload v3 (released late 2024) runs natively inside Next.js — the same app/ directory, the same server. There is no separate API server. Your Next.js route handlers are your API. This is the most interesting architectural shift in headless CMS in years.
Because it lives inside Next.js, there is no licence cost and no hosted tier to outgrow. The database is yours (Postgres or MongoDB). The admin panel ships at /admin as a Next.js route group.
Costs on free: Vercel Hobby plan limits serverless function duration and you will hit those limits with Payload's admin panel operations. Hobby is also limited to personal, non-commercial use. Upgrade to Vercel Pro ($20/month) or self-host on a VPS. Postgres on Neon's free tier (at the time of writing: 1 GB storage and 100 CU-hours per project) works for development; for production, Neon's Launch plan is usage-based pay-as-you-go rather than a fixed fee.
What you lose: no managed backups, no visual editor, no CDN image transforms (you wire Uploadthing or S3 yourself), and the plugin ecosystem is early compared to Strapi. The payoff is zero API quota anxiety — your Next.js RSC queries hit the same database directly, not an HTTP API.
// app/posts/page.tsx — querying Payload v3 directly inside Next.js
import { getPayload } from "payload";
import config from "@payload-config";
export default async function PostsPage() {
const payload = await getPayload({ config });
const { docs } = await payload.find({
collection: "posts",
sort: "-publishedAt",
limit: 10,
});
return <ul>{docs.map(p => <li key={p.id}>{p.title}</li>)}</ul>;
}
Honest pick by project type
Personal blog or open-source project with no team: Sanity free. Full GROQ, Studio embeds cleanly, TypeGen works, and 1M CDN requests/month is plenty for low traffic. The hard caps (no paid overages on free) are the only watch point.
Agency staging / proof of concept: Sanity free or Contentful Community. Both give you enough to demo to a client. Sanity wins on DX; Contentful wins if the client's team already knows it.
Solo founder building an MVP, zero infra budget: Payload v3 on Vercel Pro + Neon Launch. Combined cost is $20/month plus Neon usage, no API quota to hit, schemas live in your repo alongside the app. The trade-off is you own the ops.
Team of 3+ non-technical editors who need visual page building: Storyblok is the right tool but not on the free tier — budget for it from the start or choose a different CMS.
Client project that will definitely scale past 50k monthly visitors: None of these free tiers. Sanity Growth ($15/seat) or Payload self-hosted on a dedicated VPS is the honest starting point. Free tiers are for prototypes, not production traffic.
The recurring pattern: free tiers are genuinely useful for learning the API, building the integration, and demonstrating to clients. The moment you have real editors publishing real content to real traffic, the caps that matter are hard quota stops (Sanity), the non-commercial restriction (Contentful), seats (Storyblok), and server costs (Payload, Strapi). Plan for the first upgrade before you start, not after you hit the wall at midnight before a launch.

Bandwidth caps were the exact reason I stopped evaluating SaaS free tiers and just put UnfoldCMS on a cheap VPS — predictable costs, no surprise overage at 3am. Hit Sanity's 1GB limit in day two testing an image gallery, and that was enough to make the call.
