Builder.io is an AI agent that works inside your own codebase, turning a prompt, a Figma file or a screenshot of an existing page into working code it ships as a pull request. Whether it fits you depends on whether you have a connected GitHub, GitLab or Bitbucket repository to wire it into, since that connection is how it generates and ships anything.
What is Builder.io?
Builder.io is made by Builder.io, headquartered in the San Francisco Bay Area, United States. It runs in the browser and as a desktop app for Mac and Windows, and its agent offers models from Anthropic, OpenAI and Google, defaulting to Claude Sonnet 4.
Designing screens in Builder.io
Chat instructions to the Builder agent generate and edit real UI and code inside a connected codebase, rather than a single from-scratch generator button. A Chrome extension imports the layout of any website, and a Figma plugin converts Figma designs into deployable code. Prototypes run on a team's own real components, and can be shared as a working preview that people click through and comment on.
Design System Intelligence connects a design system repository as context, so generated UI is built from your actual components and tokens rather than a generic library, and there is no separate ready-made template gallery to start from instead. Handoff arrives as working code in a pull request against the real repository, ready for the team to review, rather than a spec-only inspect mode. Builder.io has no structured user testing feature; prototypes can only be shared for comments.
Working with other people
Real-time multiplayer editing is included on every plan, and the Team plan adds commenting and peer review workflows. A CLI and a Run API let teams trigger Builder programmatically, and it integrates with Slack, Jira, Supabase, Neon, Netlify, Zapier, Figma, Linear, Contentful, Sanity, Notion, GitHub, GitLab, Bitbucket and VS Code. It runs in the browser or as a desktop app for Mac and Windows. Single sign-on is available on the custom-quoted Enterprise plan.
Builder.io pricing: what each plan gives
The free plan costs nothing, for one user expandable up to five, with 60 Agent Credits a month or 15 a day, a connection to GitHub, GitLab or Bitbucket, the Figma plugin and VS Code extension, and an admin-only role. Pro costs $24 per user a month, the same whether billed monthly or yearly, with 500 monthly Agent Credits. Team costs $40 per user a month, also unchanged by billing period, and adds commenting and peer review on top of Pro.
Extra Agent Credits can be bought in blocks of 500 a month for $25 a month on Pro and above. Builder.io has no time-limited trial; the free plan serves that purpose instead.
Privacy and support
Free-plan customers are always used to train Builder's AI, with no opt-out; Pro and Team customers can toggle AI training off in account settings, and Enterprise customers are excluded by default. Builder.io holds a SOC 2 Type 2 report, and single sign-on is offered on Enterprise. Builder.io does not claim ownership of a customer's output, so it can be used commercially.
Support runs through email, a community forum and a help center, with standard support on Pro and priority support on Team.
Who Builder.io suits
Builder.io suits teams with an existing frontend codebase who want an AI agent generating real UI from a prompt, a Figma file or a screenshot, built from their own components and design tokens, and shipped as a reviewable pull request.
It suits less well anyone without a codebase to connect it to, or anyone on the free plan who doesn't want their inputs and outputs used to train Builder's AI, since that plan offers no opt-out. It also suits less well anyone who wants a ready-made template to start from, or a way to test a design with real users, since neither is offered.
How Builder.io compares
Builder.io scores 8.0 out of 10 among the AI UI design tools we rate. These three do the same job and are the closest to it, compared on what each vendor publishes.
Figma
Builder.io turns a screenshot, sketch, or URL straight into a working design or codebase; Figma does not offer that as a native feature. Figma instead gives you a ready-made template library to start from, which Builder.io does not have, and it exports to 8 file formats against Builder.io's 2, since Builder.io's output is code pushed as a pull request into your own repo rather than a design file. Both let several people edit the same project live and run comments for approval.
Pick Figma if you want a template library to start from and design files in more export formats.
Pick Builder.io if you want a screenshot, sketch, or URL turned straight into working code in your own repo.
Visily
Builder.io's cheapest paid plan is $24 against Visily's $14, and it connects to far more of a team's stack, 15 integrations against Visily's 4, plus a public API for triggering runs programmatically that Visily does not have. Visily instead gives you a template library to start from and runs on 1 platform to Builder.io's 3. Both let several people edit the same project live, support comments for approval, and keep a free plan.
Pick Visily if you want a template to start from and a lower entry price.
Pick Builder.io if you need many integrations and a public API to automate builds.
UXPin
UXPin's cheapest paid plan is $49 against Builder.io's $24, roughly double. Builder.io connects to far more of a team's stack, 15 integrations against UXPin's 7, and documents a public API for triggering runs, which UXPin does not offer. UXPin instead ships a template library to start from and its React output can target 5 different component libraries. Both let several people edit the same project live and run comments for approval.
Pick UXPin if you want a template library and more code targets to choose from.
Pick Builder.io if you want more integrations and a public API at a lower starting price.
