Builder.io
Also known as: Builder Code, Builder 2.0, builder.io, Builder.io Fusion
Builder.io is a multiplayer AI development platform where engineers, designers and product managers work with coding agents on a team's real codebase and design system. Agents start from Slack threads, Jira tickets or branches pushed from Claude Code or Cursor, run in parallel in cloud containers with live previews, use the company's own components, and return pull requests through the existing Git review, with review agents checking and fixing code first.
Builder.io, Inc. sells Builder Code, its AI development platform, alongside Builder Content, a visual headless CMS for marketing teams. Builder Code is built for teams rather than a single developer: a product manager can spin up an agent on a fresh branch, a designer can refine the interface in the same project with live cursors, and an engineer reviews the code as it changes.
Agents run in parallel, each in its own cloud container with a full development environment and a live browser preview, so a team can assign a batch of tickets and come back to finished pull requests, watching progress from one dashboard. Work starts from an @Builder.io mention in Slack, which reads the thread and posts previews back, from a Jira ticket assigned to the bot, from a branch pushed from Claude Code, Cursor or VS Code, from the Chrome extension on a running site or from Figma designs.
Design System Intelligence indexes the company's component library and tokens so generated code uses its own patterns, and built in MCP servers for Supabase, Neon, Netlify, Linear and Zapier plus custom MCP servers bring outside data into generation. Review agents run static analysis, flag security, performance and accessibility issues against ESLint rules and performance budgets, and push fixes before a person reviews. Every change lands as a pull request on GitHub, GitLab, Azure DevOps or Bitbucket for the team's normal approval, and models include Claude, Codex and Gemini.
Free gives one user 60 agent credits a month; Pro is $24 per user a month with 500 credits, MCP servers, custom domains and credit rollover; Team is $40 per user a month with Slack and Jira agents, roles, comments and reviews, custom MCP servers and usage metrics; Enterprise adds SSO, role based access control, privacy mode, enterprise Git hosts and SLAs, with more credits at $25 per 500 a month. Builder.io reports SOC 2 Type II compliance.
Builder.io fits product teams with an established codebase and design system that want designers and product managers to ship real changes through engineering review, and engineering teams that want to parallelize tickets across agents. It fits less well for solo builders starting from nothing, teams that need agents to wake on a schedule, or buyers who want automated browser QA today, since QA agents are still to come.

Integrations
Git hosting on GitHub, GitLab, Bitbucket and Azure DevOps, with Bitbucket Enterprise, GitLab Enterprise and self hosted providers on Enterprise; Slack and Jira bots; built in MCP servers for Supabase, Neon, Netlify, Linear and Zapier, plus custom MCP servers; a Figma plugin, VS Code extension, Chrome extension and handoff from Claude Code and Cursor; SSO through Okta, Google Workspace and Microsoft Entra. Frameworks include React, Vue, Svelte and Angular, and models include Claude, Codex and Gemini.
In practice
A product manager assigns three Jira tickets to the Builder.io bot; agents read the acceptance criteria, build each change on its own branch with a live preview, and a review agent fixes lint and accessibility issues before engineers approve the pull requests.
A designer opens a branch an engineer pushed from Cursor, adjusts spacing and swaps a table for a chart using the company's own components, and the engineer reviews the final diff before merge.
A team tags @Builder.io in a Slack thread about a broken checkout layout; the agent reads the thread, fixes the layout and posts a preview back into the same thread for sign off.

| Integrations & Tool Calling | Full |
|---|---|
|
Agents clone and push to repositories on GitHub, GitLab, Bitbucket and Azure DevOps, with enterprise and self hosted Git providers on higher plans, and deliver every change as a pull request. Built in MCP servers connect Supabase and Neon for database work, Netlify for deployments, Linear for tickets and Zapier for hundreds of other services, and custom MCP servers reach a company's own databases and tools, so generation can replace placeholder data with real records or read the related Jira ticket and implement against it. A Figma plugin turns designs into code, and the Chrome extension pushes visual edits from a running site straight into the codebase. Sourcebuilder.io/c/docs/builder-code-integrationsread 2026-10-18 |

| Workflow Orchestration | Full |
|
Hundreds of agents can run at once, each in its own cloud container with a full development environment, code access and a live browser preview, so a team can assign a batch of tickets and come back to finished pull requests, monitoring and steering the work across streams from one dashboard. People and agents share a branch in real time: an engineer can start hard work locally, push the branch, and a designer, product manager and QA continue on it while the engineer reviews the final diff. Review agents check each change and push fixes to the pull request on their own, closing review loops before a person steps in. Sourcebuilder.io/llms.txtread 2026-10-18 |

| Knowledge Grounding & RAG | Full |
|
Design System Intelligence indexes a company's component library, design tokens and coding standards so every generated change uses its own patterns instead of one off components, with up to three design systems on Pro and unlimited on Enterprise, and Figma tokens can be mapped to code. Projects can be pointed at chosen design systems, environment variables and runtime dependencies, and connected MCP servers let agents pull requirements from Jira tickets or data from Supabase while generating. An asset library holds shared images and files for projects. Sourcebuilder.io/c/docs/builder-code-project-settingsread 2026-10-18 |
|
| Human Oversight & Guardrails | Partial |
|
Every change ships as a pull request with a clear description, engineers approve everything before it ships, and the team's existing Git review and merge process stays in place. The Team plan adds commenting and peer reviews inside Builder and password protected previews, and teammates can watch and edit alongside an agent in real time. There is no step to approve a plan before an agent starts editing, and review agents push their own fixes to the pull request before a person reviews it. Sourcebuilder.io/llms.txtread 2026-10-18 |
|
| Security, Identity & Governance | Full |
|
Builder.io reports SOC 2 Type II compliance, with a trust center for review. Team plans add Admin, Developer, Designer and Editor roles, Enterprise adds role based access control in which designers can edit the interface but not backend logic, file level permissions set with glob patterns for sensitive code, and private projects with permissions per role or user. Enterprise single sign on connects Okta, Google Workspace or Microsoft Entra, privacy mode and training opt out are on by default for Enterprise, and site access control and a desktop only access setting restrict where projects can be opened.

|
| Observability & Auditability | Partial |
|
A single dashboard shows the progress of every running agent across workstreams, each agent exposes a live browser preview of its work, and pull requests carry descriptions of what changed. Pro keeps 30 days of activity history and Team adds usage metrics, with Enterprise organization insights listing the most active users. A step by step record of an agent's commands and decisions, or an export of agent activity to outside monitoring, is not offered. Sourcebuilder.io/pricingread 2026-10-18 |
|
| Memory & State Persistence | Partial |
|
Projects, branches, design systems and settings persist in a space, Pro keeps a 30 day activity history, and agent credits can roll over between months. Context for each task comes from the repository, the indexed design system and the ticket or thread that started it. There is no memory of past tasks, decisions or team preferences that agents write to and draw on beyond the code, project settings and history the team already keeps.

|
| Deployment & Data Residency | Partial |
|
Builder runs as a cloud service with agents in cloud containers, and development can also run locally in Docker or through the Builder Desktop app, with Enterprise able to supply custom Docker images with exact configurations and to restrict a project to the desktop app. Code stays in the customer's own repositories and reaches production through its CI/CD, and Enterprise can connect self hosted or custom Git providers. There is no self hosted Builder service and no choice of the region where Builder processes data. Sourcebuilder.io/llms.txtread 2026-10-18 |
|
| Prebuilt Agents / Templates / Packs | Partial |
|
Teams start from their own repositories and design systems rather than from a catalog of packaged agents, and Figma designs or a captured web layout can seed a change. On Enterprise, templates can be shared across spaces and a whole space can be duplicated within an organization, while Builder Content brings its own page and content templates for marketing teams. There are no ready made agents for particular roles or jobs. Sourcebuilder.io/c/docs/enterprise-hubread 2026-10-18 |
|
| Triggers & Channel Coverage | Partial |
|
Work starts from an @Builder.io mention in a Slack channel, where the bot reads the thread and posts updates and previews back, from a Jira ticket assigned to or mentioning the bot, which it reads for acceptance criteria, from a branch pushed from Claude Code, Cursor or VS Code, from the Chrome extension on a running site or localhost, from Figma, or from the web and desktop apps. Slack and Jira agents come with the Team plan, and the Agents Run API lets a CI pipeline or internal tool hand the agent a prompt. Each of these begins with a person's request or a call the team scripts; nothing in Builder starts an agent on a schedule or a monitoring signal. Sourcebuilder.io/llms.txtread 2026-10-18 |
|
| Model Flexibility & Routing | Full |
|
Teams can pick among Claude, Codex, Gemini and other models for each task and switch between them freely, with the same models a team already uses wrapped in Builder's collaboration layer, and Enterprise supports custom models for compliance needs. Agent credits carry a fixed dollar value covering the underlying model cost plus Builder's margin, so model choice changes how fast credits are spent. Sourcebuilder.io/llms.txtread 2026-10-18 |
|
| APIs / SDKs / MCP Extensibility | Full |
|
The Agents Run API starts Builder's agent from a team's own systems, such as a CI pipeline or an internal tool: a POST to api.builder.io/agents/run, authenticated with the space's private key as a bearer token, carries the prompt, the Builder user the run acts for and optional images, files or reference URLs, and returns the branch and project URL where the agent keeps working in the background. A Metrics API reports code generation usage, projects and agent events by organization or space. The builder.io CLI launches a local repository, a multi repo workspace or the desktop app, AGENT.md files give the agent standing instructions, and custom MCP servers, the VS Code and Chrome extensions and a Figma plugin extend where work comes from.

|
| Testing, Debugging & Optimization | Partial |
|
Review agents run static analysis on every change, catch style violations, flag security vulnerabilities and performance issues, and validate generated code against ESLint rules, accessibility standards and performance budgets, then fix what they flag and update the pull request. Each agent's live browser preview lets people check the result as it builds. Automated browser testing that clicks through updates and reports bugs with video is still coming soon, so tests are not yet run against the app for the team. Sourcebuilder.io/llms.txtread 2026-10-18 |

| Browser / Computer-use | Not documented |
|
The Chrome extension connects a person to a running site, localhost or a page behind a login, lets them select elements and change them visually, and captures layouts from any web page into Builder, with the person doing the driving. Agents show a live browser preview of their own work, and the Agents Run API can point an agent at a live webpage it fetches and analyzes for reference. Browser testing by QA agents is still coming soon, so no agent yet clicks through a site, operates a desktop or works in outside software on its own. Sourcebuilder.io/llms.txtread 2026-10-18 |

Pricing
Pro $24 per user a month; Team $40 per user a month
Per user subscription per space with a monthly agent credit allowance, plus pay as you go credit blocks
Included quota
Free: 60 agent credits a month, 1 user (up to 5), 1 design system. Pro: 500 agent credits per user a month, 1 user included (up to 5), 3 design systems. Team: 500 credits per user a month, up to 20 users. Enterprise: custom seats and credits.
What is public
Seat prices for Free, Pro and Team, credit allowances, the price of extra credits and the features each plan adds.
Billing mechanics
Self serve per user subscription per space, monthly or annual, with add on credit blocks; Enterprise through sales.
Cost watchouts
Slack and Jira agents, custom MCP servers and roles need Team; SSO, RBAC and enterprise Git hosts need Enterprise; running many agents in parallel burns credits quickly.
Variable cost rationale
Seats are flat, but agent credits run out with heavy or parallel use and model choice changes the spend per task, so busy teams buy extra 500 credit blocks each month.
Additional watchouts
Parallel agents multiply credit use.
Overage / add-ons
Pro and Team buy more agent credits in blocks of 500 for $25 a month; Free waits for the daily or monthly reset; unused Pro credits can roll over.
Sales call required
Mixed (some tiers require a call)
Free / trial
Free plan for one user with 60 agent credits a month (15 a day)
Lowest paid plan
Builder Code Pro at $24 per user a month: 500 agent credits per user, up to 3 design systems, built in MCP servers, custom domains
Commercial notes
Builder Content, the visual CMS, is priced separately on its own tab; Code and Content can be used together.
Key ambiguities
Whether the $24 and $40 seat prices are the monthly or the annual rate is not clear from the text, and how many credits a typical task uses is not given.
Support SLA / resale
Uptime and premium support SLAs on Enterprise.
Missing data
Annual discount, credits per task and Enterprise pricing.
