Puck vs Builder.io: the same editing model, with and without a vendor
Both let non-developers arrange your React components. Puck is MIT licensed and stores JSON in your database; Builder.io is a hosted platform with credit-based pricing and its own CDN.
TL;DR
- Puck and Builder.io implement the same core idea — visual editing of your registered components — with the difference that Puck is a library you own and Builder.io is a platform you rent.
- Puck is MIT licensed, 90.4 kB gzip in our measurement, and stores typed JSON wherever you choose; Builder.io's 2026 pricing is credit-based from around $19 per user per month.
- What Builder.io adds beyond editing — personalisation, A/B testing, CDN delivery, governance — is the part Puck has no equivalent for, and the part most teams do not initially need.

Best fit by requirement
Generated from the dataset: only requirements where both facts are verified and they differ. Neither product is better overall — it depends on which of these you actually need.
- If you need an open-source licence, Puck has an open-source core (MIT); Builder.io does not.
- If you need self-hosting, Puck runs on your own infrastructure; Builder.io does not.
- If you need white-label, Puck can ship without vendor branding; Builder.io only partly or through an add-on.
- If you need Vue support, Builder.io has a first-party Vue integration; Puck does not.
- If you need Angular support, Builder.io has a first-party Angular integration; Puck does not.
- If you need AI features, Builder.io offers AI generation; Puck does not.
- If you need a lower entry price, Puck costs nothing to license, against about $19/month for Builder.io.
Puck vs Builder.io: analysis
The same premise, a different business model
Register your components; let non-developers arrange them; render the result with the same components. Both products do this, and both avoid the canvas-versus-production drift that HTML-based builders suffer.
Everything else is the difference between a library and a platform.
Where Builder.io fits better
The workflow around editing. Previews, roles, scheduling, approvals — the machinery a marketing organisation needs, none of which Puck has.
Personalisation and experimentation. Targeting and A/B testing at the content layer are substantial products that a library cannot replace.
Delivery. Content served from Builder's CDN with caching handled.
More frameworks. React, Vue and Angular first-party, against Puck's React-only model.
No build required. The system exists on day one; with Puck, previews and publishing are yours to assemble.
Where Puck fits better
Cost predictability. MIT licensed, free, no credits, no per-user pricing. Credit-based billing is the most common complaint we see from teams evaluating Builder alternatives, and Puck removes the question entirely.
Data in your database. Pages are JSON you store, back up and query alongside everything else. No data-residency conversation, no vendor availability in your render path.
You can ship it to your customers. A multi-tenant page builder inside your product is a normal Puck project and an awkward Builder.io one.
No vendor risk. No pricing changes, no roadmap surprises, no sunset.
Smaller surface to learn. A config object against a platform.
The real decision
Ask who the editor is for.
If the answer is "our marketing team", Builder.io is doing far more than editing and the comparison should include those features rather than pretending it is a library. Building previews, roles and scheduling on Puck to match is months of work that does not differentiate your product.
If the answer is "our customers", Builder.io is the wrong shape at a structural level, and the question becomes whether Puck alone is enough or whether you need a white-label SDK.
Migration
Builder.io to Puck: export content via the API and transform Builder's model into Puck's config-plus- data shape. Tractable for pages built from a constrained component set, manual for bespoke ones. You also rebuild the workflow features you were relying on, which is usually the larger task.
Puck to Builder.io: register the same components in Builder and transform the JSON. Mechanically easier, because you are moving toward a system with more capability rather than less.
Which to choose, by requirement
Marketing-led, workflow-heavy, engineering-constrained: Builder.io. Product-led, customer-facing, cost-sensitive, or data-residency-bound: Puck.
The middle case — a marketing team that only needs page composition without personalisation — is where Puck plus a weekend of preview plumbing beats a platform subscription, and it is more common than vendors suggest. Our Builder.io alternatives guide covers the rest of the shortlist.
Decision checklist
- Who is the editor for — our marketing team or our customers? Builder.io is built for the first and structurally awkward for the second.
- Do we need personalisation and experimentation, or just page composition? Most teams need only the second and pay for the first.
- Can content live with a vendor? If not, Puck is the only one of the two still in the running.
- How predictable does the bill need to be? Credits move with usage; MIT licensing does not move at all.
- What would we build around Puck? Preview, publishing and roles are the realistic list, and for a small marketing team that is a week, not a quarter.
The number that matters
90.4 kB gzip, our measured size for Puck with React external — and a licence cost of zero against credit-based pricing that starts around $19 per user per month. The interesting comparison is not those numbers but what sits between them: roughly one week of plumbing for a simple marketing workflow, and considerably more if you need approvals, scheduling and targeting.
Frequently asked questions
- Is Puck a free alternative to Builder.io?
- For the visual editing itself, yes, and it is the closest one. It does not replace Builder's personalisation, experimentation, CDN delivery or enterprise workflow.
- Which is better for a marketing team?
- Builder.io, if the team needs to work independently of engineering at scale. Puck requires your engineers to build the surrounding workflow — previews, publishing, roles.
- Which is better for a product feature?
- Puck. If the editor is a feature your own customers use, a hosted vendor platform with its own accounts is structurally awkward, and Puck's data-in-your-database model fits.
