Builder for App Development
Ship features and fixes
in your real app
Build with agents, while product, design, and engineering shape the work together.
Build in your existing codebase
Agents build from your repo, design system, and project rules, so every change fits your architecture and patterns.
Collaborate on the feature
PMs, designers, and engineers shape and preview the same feature on a shared branch, so everyone's feedback is already in the PR.
Send it through your review process
Work from Builder or your own coding tools goes through the same checks, approvals, and review, so engineering decides what merges.
Cross-functional app development
Each team owns the part they know best
Build with the stack your team already uses
Use your framework
Build in the frontend your product already runs on, with the routes and patterns that decide what can ship.
Keep your Git workflow
Move work through the branches, pull requests, checks, and approvals your engineering team already trusts.
Shared coding environments
Move branches between Builder and tools like Cursor, Claude Code, and Codex so engineers can code locally while the team refines in Builder.
Extend with MCP connectors
Builder integrates directly with tickets, docs, and data sources, and reaches the rest of your internal tools through MCP connectors.
Enterprise-ready
Security your platform team
can sign off on
Builder is built for engineering teams that need AI-assisted development and publishing workflows without giving up security, governance, or production control.
Customer stories
Designs that shipped as designed
“Builder hits this nice middle ground… it’s structured enough for developers to stay in control, but flexible enough to let other teams move fast without creating chaos.”
“A page that took three engineers a month to build can now be created in a couple of days.”
“Builder makes everyone’s lives easier, it makes it easier for us to maintain, and it makes it easier for the brand teams to maintain.”
FAQs

Teams use Builder to create app features, internal tools, dashboards, product UI, and production-ready frontend work.
Both. You can start from a new prompt or connect an existing repo so the work fits the app your team already ships.
Cursor, Claude Code, and Codex are developer coding environments. Builder gives product, design, and engineering the same branch, preview, comments, and pull request.
Builder starts from your existing codebase, design system, project rules, and Git workflow, so features and fixes stay connected to the systems your team already uses.
Yes. Designers, PMs, and other teammates can refine UI, copy, layout, states, and flows visually on a branch. Permissions, pull requests, and reviews keep engineering in control of what ships.
Yes. Builder works from your repo, components, and project rules so generated work fits your app. Your team still reviews, tests, and decides what gets merged.
Yes. Builder supports branch and pull request workflows, including Send PR, Update PR, and Auto-push for teams that want changes to keep syncing. Builder’s bot can also review the pull request.
Ship the fixes and features your team can’t wait on
Start from feedback or a spec, refine it with the team, and send the branch through review.
