b10cks vs. Prismic

Prismic Built the Slice. Then Charged You Per Language, Per User, Per Tier.

Prismic's slice-based model is a genuinely good idea for structured page building. But locale limits that cap at 8 even on the $675/month plan, user seats that run out on plans up to $150/month, and no self-hosting mean the constraints add up fast. b10cks gives you unlimited locales, unlimited editors, and a complete platform – starting free.

The Short Version

Good content model. Complicated math.

Prismic popularized the slice concept — reusable, composable page sections that developers define and editors assemble. It's a genuinely solid approach that influenced how an entire generation of headless CMSs thinks about content structure.

The pricing model, though, is built around per-repository plans with hard limits on the things teams use most: users, locales, and environments. A 7-person team already needs the $25/month Small plan. Needing 5 locales pushes you to Medium at $150/month. Wanting development environments means either Platinum at $675/month or a $3,000/year add-on.

b10cks uses the same composable block model — blocks are b10cks' native architecture — and charges for storage and traffic. Locales, editors, content types, and environments are unlimited on every plan.

The Key Differences

Locale Limits Are the Defining Problem

Prismic's localization limits are the most aggressive in the headless CMS market. At $675/month (Platinum), Prismic includes 8 locales. Not unlimited. Eight.

For any team with modest global ambitions — say, a European SaaS covering English, German, French, Spanish, Italian, Dutch, Polish, and Portuguese — you're at Platinum pricing just to cover the locale count. On Medium ($150/month), you get 5 locales.

b10cks has no locale limits on any plan. Every language your product needs is available from day one.

Seat Tiers Are Narrow

Prismic's user limits escalate quickly: 1 user (Free), 3 (Starter), 7 (Small), 25 (Medium), Unlimited (Platinum). For most real teams, this means:

  • A team of 4: $25/month (Small)
  • A team of 10: $150/month (Medium)
  • A team of 30: $675/month (Platinum)

b10cks has no per-seat limits. Unlimited editors on every plan.

Development Environments Are Expensive

Prismic's development environments — isolated staging and testing environments where developers can work on schema changes without affecting production — are not available below Platinum, and even on Platinum they require a $3,000/year add-on on invoiced plans.

For development teams that practice proper staging workflows, the absence of affordable environments is a real limitation.

b10cks includes environment branching from the Growth plan upward, without a separate add-on.

Custom Roles and SSO: Enterprise-Only

Custom roles (beyond a few predefined options) require Medium or above. SSO is Enterprise-only. For organizations with an identity provider and a need to define precise editorial permissions — which is the norm, not the exception — Prismic's structure forces a premium commitment.

b10cks includes SSO and fully configurable custom roles on every plan.

Slice Machine: Power at a Price

Prismic's Slice Machine is genuinely useful — a CLI-based workflow where developers define slices in code, sync to the Prismic model, and editors use the assembled slices. For teams where the developer defines the components and the editor assembles pages, it works well.

The trade-off: your content model lives in your codebase, which means schema changes require a deploy cycle. Non-technical teams cannot modify the content model without developer involvement.

b10cks' infinite canvas allows content architects to model blocks visually and modify structure without touching code. Changes propagate to the editor immediately. Both approaches are valid — the right choice depends on how much control you want to give content teams over the model.

Who Should Use Prismic

Prismic is a solid choice when:

  • Your team follows a strict developer-defines, editor-assembles workflow and you want schema-as-code built into Slice Machine
  • You're in the Next.js/React ecosystem and want tight Slice Machine integration with your component library
  • Your locale count fits within the plan limits and user count stays below 25
  • You don't need custom roles or SSO

Where b10cks Is the Better Choice

  • You need more than 8 locales — or any locales without paying per tier
  • Your team has more than 25 editors (or more than 7 without paying $150/month)
  • You need custom roles or SSO without an enterprise contract
  • You want self-hosting as an option
  • You need development environments without a $3,000/year add-on
  • You want usage-based pricing that scales with your traffic, not your team size

Unlimited locales. Unlimited editors. One predictable bill.

b10cks gives you the block-based composability Prismic is built around — without the locale caps, the user tiers, or the enterprise-only features.
