What makes Fei Studio enterprise-ready?

Fei operates on your real product and understands your actual codebase, not prototypes. The ACE engine maintains architectural patterns, component structures, naming conventions, and internal standards so changes remain consistent and safe. Developers retain full control through review and approval workflows.

Does Fei require access to our entire repository?

Yes. Fei needs full visibility into the repo to understand component relationships, design systems, and architectural rules. Access is read-only unless you explicitly enable write permissions for automated PR creation.

How does Fei handle large projects or complex products?

Fei uses hierarchical retrieval to manage large-scale contexts efficiently, narrowing focus from project → package → module → function. A planner and router system breaks down large tasks into smaller, targeted subtasks. Fei also uses sub-agents for knowledge extraction and context preparation before execution. For large or monorepo setups, Fei maintains per-package indexes and a dependency-aware workflow, keeping edits localized yet consistent.

What does “one-shot” mean in Fei?

“One-shot” means Fei can handle a task end-to-end autonomously – from understanding the spec to producing validated code – without step-by-step input. Internally, Fei plans, edits, validates, and self-checks iteratively, but the user experiences it as a single-shot process. It builds the context it needs live, executes the change, verifies correctness, and presents a complete, ready-to-review result, delivering the power of iteration with the simplicity of automation.

Does Fei integrate with other enterprise systems or developer tools?

Yes. Fei integrates natively with Git for version control and can connect to internal systems like SSO, SAML, and issue trackers such as Jira or Linear. It focuses on front-end work, so it does not require or request access to production databases or third-party services like Stripe, Salesforce, or Snowflake.

Do developers still review the code?

Always. Fei generates production-grade updates, but developers maintain oversight. Every change flows through your existing review, approval, and merge processes.

Can Fei handle large enterprise repos?

Yes. ACE was designed specifically for multi-package, multi-owner, and legacy-heavy repositories. It builds deep structural understanding across the codebase so Fei can reliably update complex systems.

Can Fei integrate with our existing workflow?

Fei works alongside GitHub, GitLab, Bitbucket, Jira, Figma, and your internal review processes. It doesn’t replace engineering tools; it reduces the friction between Product, Design, and Dev.

What is Fei Studio?

Fei Studio is where product teams, designers, and engineers collaborate directly on the real product. It generates working components, documentation, and updates in your actual codebase. It is deployed as a web based application, accessible to engineering and non-engineering users.

What is Fei IDE?

Fei IDE is the engineering environment built around Fei’s autonomous abilities. It analyzes your codebase, proposes changes, creates new components, and integrates them directly into your repository. It is deployed as an extension in Cursor, VSCode, or any fork.

How do Fei Studio and Fei IDE work together?

Fei Studio and Fei IDE share their deep understanding of your actual codebase, allowing the engineering team to tune the agent’s coding standards and having it automatically apply to all of the product team’s work in Fei Studio.

What is ACE?

ACE is the Agentic Context Engine used by Fei Studio and Fei IDE to understand your entire codebase. It provides structured, deterministic context for stable reasoning and updates with every merged branch.

Is ACE something we have to install or operate?

No. ACE runs behind Fei Studio and Fei IDE and self-maintains. You’re welcome to tune it but you do not need to maintain or configure it.

Does Fei work with our existing tech stack?

Yes. Fei reads your repository file by file to understand your entire stack, no manual configurations needed.

How does Fei handle security and data protection?

Fei operates in an enterprise-grade security model with strict isolation, minimal data retention, and fully auditable workflows.

Are you SOC2 compliant?

Yes. Fei Studio, Fei IDE, and ACE infrastructure are SOC2 certified.

Where does our code and data go?

All processing happens inside a secure execution environment. Your data is not used for training or external purposes. ACE maintains an annotation map of your codebase to help point the agent where to look inside the codebase as the agent works without having ACE retain any of your code.

Do you support on-prem or private deployments?

Yes. Private deployments are available for organizations with strict isolation or regulatory needs.

How does Fei integrate into our workflow?

Fei plugs directly into repositories, it can read your Figma files and your Jira/Linear tickets, plugging directly into your product development processes. No workflow changes are required.

Is Fei safe to use on large, legacy, or messy codebases?

Yes. ACE was designed for realistic, fragmented, or partially documented systems.

How do we get started?

Request access to the Fei Studio Beta or contact sales for company and enterprise programs.

What is Fei Studio used for?

It is the workspace where product, design, and engineering collaborate on the real product. Teams define behavior, UX, flows, and component intent. Fei then generates production-ready outputs aligned with the codebase.

How is Fei Studio different from Lovable and other vibecoding tools?

Fei Studio works on existing enterprise-level products and produces senior-developer-quality output aligned to company standards, design systems, and tribal knowledge – it understands your codebase and directly adds to it.

How is Fei Studio different from Cursor & Claude

Cursor and Claude are developer coding assistants inside an IDE and depend on the user’s knowledge of the codebase. Fei Studio works for the whole product team, finds the right components on its own, understands the repo, and generates developer-ready updates without complex prompting. ACE provides full contextual understanding, allowing Fei Studio to execute the entire front-end engineering workflow.

How does Fei Studio stay aligned with our codebase?

Fei Studio runs on ACE, which maintains an accurate model of your repository, design system, components, coding practices, and infrastructure configurations. The same rules and guardrails used in engineering also govern Fei Studio.

Does Fei Studio replace Figma or our design system?

No. Fei Studio works with your current design tools and system. You can pass it your Figma designs and it will implement it using your codebase’s components and practices. Some organizations use Fei without a Figma design and leave it to implement the specifications using the codebase’s design system – naturally matching your design principles that it learned directly from your code.

What kind of outputs can Fei Studio produce?

Any UI element you can describe: buttons, modals, layouts, full pages, multipage flows, tables, graphics, UX logic, validations, and more. The final output is high-quality code ready for approval. Of course, it can also update existing screens and components to help you clean up existing UI in your product.

Can non-technical team members use Fei Studio?

Yes. It enables PMs, designers, and business stakeholders to prototype and build Front End and logic within your actual frameworks and standards.

How does Fei Studio integrate with Fei IDE?

Fei Studio creates high-quality code and sends it to your dev team via a Pull Request. Your dev team can merge the changes or continue the work using Fei IDE. Both share the same context model through ACE.

Does Fei ever train on or retain customer data?

No. Fei does not train on customer data and does not store customer code. It uses static analysis and project-specific embeddings only.
