Builder.io lets engineers, designers, PMs and marketers build on a real codebase with AI agents, pairing a visual IDE for apps with a visual headless CMS for pages and campaigns.

Builder.io is a collaborative platform for building software with a team and AI agents, where engineers, designers, product managers and marketers work on the same production code instead of handing files between tools.
It is sold as two products that can be used separately or combined: Code, a visual IDE that works inside an existing repository, and Content, a visual headless CMS for pages, campaigns and structured content. Builder.io also refers to the two products as Fusion, its AI development platform for product, design and engineering teams, and Publish, its visual headless CMS for content teams.
The company was co-founded by Steve Sewell and Brent Locks, who had built web applications together at the fashion retailer ShopStyle. A 2021 report on the company described a drag-and-drop visual editor and headless content management system that let marketers, product managers and designers build content from existing components, run A/B tests and measure conversions.
The most important thing to know before choosing a plan is that AI work, hosting and Builder-managed databases are all metered in a shared pool of Agent credits, while seats are priced per user.
The delivery path is deliberately conventional. Approved changes become pull requests that move through the team's existing pipeline, and for codebases behind a firewall Builder connects to internal Git, registries and APIs over a private link. That makes Code closer to a collaborative layer on top of an existing repository than to a standalone app generator.
The two products share components in both directions. Components created in Code can be used by the whole team as part of the design system in Content. Content created in Content can be pulled into apps and UIs built in Code.
Credits are consumed according to input tokens, output tokens and the per-token rate of the selected model. The model dropdown shows each model's quality as a letter grade and its cost as a multiplier of the base credit value, which is pegged to Claude Haiku 4.5; a model with a 0.1x cost gives roughly ten times the prompts for the same credits. Admins can restrict which models are available and pick the default model behind the Auto setting.
Builder's documentation notes that adjusting these rules may require the assistance of a developer.
The customer stories on Builder's own site are vendor-selected testimonials rather than independent measurements. In one of them, a website optimization manager at Zapier says the team launched more than 250 new pages that attract around one million monthly visitors on average, and that it can now run website experiments.
Builder.io is built around several roles working on the same code:
It is a weaker fit for teams that need strict data privacy controls but do not want an Enterprise contract, because Privacy Mode is designed for enterprise customers who require strict data privacy controls.
Builder.io pricing for Code is per user, with Agent credits attached to each paid seat. The table reflects the self-serve Code plans as captured on October 6, 2026.
| Plan | Price | Users and credits | Notable additions |
|---|---|---|---|
| Free | $0 | Up to 5 users, 60 monthly Agent Credits with a 15 daily limit | GitHub, GitLab and Bitbucket connections, Figma plugin, VS Code extension |
| Pro | $24 per user/month billed annually, or $30 billed monthly | Up to 5 users | Pay-as-you-go usage and Agent Credit rollovers |
| Team | $40 per user/month billed annually, or $50 billed monthly | Up to 20 users | Slack and Jira agent, peer reviews, team roles, AI training opt-out |
| Enterprise | Custom pricing, service capacity and terms | Custom seats and credits | SSO, Privacy Mode, design system intelligence |
Each Pro or Team seat includes 500 Agent credits a month, and the allowance resets each month on the date the subscription started. More credits can be bought in increments of 500 for $25 per month. Unused credits on Pro, Team and Enterprise roll over up to the plan's monthly capacity.
No list prices for Content (the visual CMS) appeared on the pricing pages checked; Content Space subscriptions are configured with a monthly volume of views and bandwidth in addition to seats and credits. Builder notes that plan features, pricing and limits are subject to change.
Builder.io overlaps with AI app builders on the Code side and with headless CMS platforms on the Content side, so the right comparison depends on which product is being evaluated. Builder's own comparison pages are vendor-authored positioning rather than independent reviews.
Builder makes no warranty about the accuracy, completeness or reliability of AI output and is not liable for errors in it. Output may not be unique, and the AI may generate the same or similar output for other customers. AI output interpretation and prompt optimization are outside the scope of technical support and are not valid grounds for a credit refund.
Under Builder's AI terms, the customer keeps sole ownership of both the input it provides and the output the AI generates, as between Builder and the customer. Builder may use the output to provide the service.
Builder offers models from Anthropic (Claude), OpenAI (GPT), Google (Gemini) and other providers. The Auto setting chooses a model for each task and is the default on self-serve plans.
A cancelled subscription stays active until the end of the current billing period, after which the account moves to the Free plan. For refunds, the support team reviews each request and initiates refunds as needed after verifying the plan change. The SaaS Services Agreement, by contrast, states that all fees are non-refundable except as expressly provided in that agreement.
