Builder.io vs Kirby

Builder.io has a free plan for up to five users, with 15 credits daily and 60 monthly. Pro costs $24 per user per month and includes 500 monthly credits per user; Team is $40 per user per month with the same credit allowance. Annual rates are not published. Pro and Team users can buy 500 additional monthly credits for $25. Enterprise pricing is custom.

Kirby charges once per site: $115 for Basic or $399 for Enterprise, with one installation on one domain and all features included on both plans. Basic is for organizations under $1 million in annual revenue or funding; Enterprise has no revenue limit. Kirby has no free plan, but local development and private test servers have no time limit. Optional three-year update extensions cost $65 for Basic and $285 for Enterprise, excluding VAT. A 5% volume discount applies to five or more licenses.

Builder.io combines app development tools, a visual editor, and an agentic CMS. Its visual canvas connects production UI to components and design tokens, while the CMS supports creating and managing content with prompts, then previewing, approving, and publishing updates. Teams can route changes through their existing Git review workflow. Builder also lists A/B testing and personalization for content and experiences. Its plans include different credit allowances and design-system limits: Free includes one design system, while Pro and Team include up to three. Enterprise includes unlimited design systems.

Kirby is a customizable website CMS centered on its Panel and file-based content. Its homepage example organizes content into folders and text files, including project titles and URLs, team members, and client organizations. Customers describe the Panel as simple and say Kirby can be adapted to client needs. The published material does not list Builder-style A/B testing, personalization, or Git review features for Kirby, so teams comparing those workflows should verify them before switching. Builder’s feature set is aimed at editing production UI and publishing; Kirby’s is presented around managing website content.

Kirby has the stronger ease-of-use review score: 8, compared with Builder.io’s 6. The review material specifically describes Kirby’s Panel as simple to use. Its file-and-folder approach may also suit teams comfortable managing content in that structure, though the published sources do not detail the setup process.

Builder.io’s visual editor is intended to let teams edit production UI, but it is tied to components, design tokens, and a Git review workflow. That makes it a more workflow-dependent choice than a standalone visual builder might suggest. The review calls it worth considering, not friction-free. If your team already reviews code changes through Git, Builder may fit; if you mainly need a customizable website CMS with a simple Panel, Kirby has the higher ease score.
