Create and Manage Projects in Windsurf Easily

Windsurf project management does not work the way most editors do. There is no "New Project" wizard, no scaffolding dialog, and no proprietary project file to maintain. Windsurf treats a folder as a project, and the depth of AI assistance you get from Cascade depends almost entirely on how well that folder is structured and indexed.

This guide covers project creation, codebase indexing, multi-file workflows, Git integration, and large-project best practices from the ground up. Whether you are starting a fresh codebase or opening an existing repository, the patterns here apply from day one.

Key Takeaways

• A project is a folder: Open any directory and Windsurf begins indexing it automatically, with no project file or configuration wizard required.
• Codebase indexing drives Cascade's awareness: Without indexing, Cascade only sees the currently open file. With it, Cascade navigates, searches, and edits across your entire repository.
• Cascade handles multi-file changes natively: You do not need to manually open every file you want to modify. Cascade reads the project structure and edits across files in a single run.
• Git is built into the Windsurf interface: Stage, commit, branch, and review diffs without leaving the editor. Cascade can read your Git state to inform its suggestions.
• Large projects require deliberate scoping: The bigger the codebase, the more important it is to use @ mentions and explicit file references to keep Cascade focused on the right scope.
• Rules files set persistent project-level instructions: A .windsurfrules file gives Cascade standing instructions for every session in that project, reducing correction cycles over time.

How Do You Create and Open a Project in Windsurf?

A project in Windsurf is any folder you open via File > Open Folder. There is no project file format, no .windsurf config required for basic use, and no setup wizard to complete. Opening a folder is all it takes to start a session.

Windsurf's folder-based model is intentionally simple. The moment you open a directory, Windsurf begins indexing it and Cascade becomes available for that codebase.

• To create a new project: Create the folder locally, open it in Windsurf via File > Open Folder, and Windsurf handles the rest automatically on first open.
• On first open, Windsurf performs: An index scan of the directory, language detection, and Cascade activation, all without any manual configuration step.
• To open an existing codebase: Clone the repository first via terminal or Windsurf's built-in Git UI, then open the cloned folder. Windsurf does not clone directly from a URL in the file picker.
• Multi-root workspaces are supported: Windsurf inherits VS Code's workspace architecture, allowing multiple folders open simultaneously when a workflow spans more than one repository.
• Workspace vs. folder distinction matters: A standard single-folder open is sufficient for most projects. Multi-root workspaces add complexity and are worth using only when the workflow genuinely requires it.

For developers switching from another editor, understanding how Windsurf works as an IDE first will make the folder-based project model easier to navigate from day one.

How Does Windsurf Index and Understand Your Codebase?

Windsurf scans the project folder on open and builds an internal representation of the codebase. This index is what allows Cascade to understand structure, symbols, and file relationships across the entire project, not just the currently open tab.

Indexing is the mechanism behind every Cascade feature that references project-wide context. Getting it right is not optional for serious use.

• Indexing triggers automatically: On first open for new projects, Windsurf starts indexing immediately. A manual re-index is available via the command palette if the project structure changes significantly.
• What gets indexed: Source files and configuration files are indexed. Node_modules, build output folders, and .gitignored paths are excluded by default, keeping the index clean and focused.
• How to verify indexing is active: The Cascade panel shows whether codebase context is enabled. The @ symbol in prompts confirms which files are currently in scope for the session.
• The .windsurfrules file is a high-leverage setup step: A plain text file at the project root, it gives Cascade standing instructions for naming conventions, preferred libraries, and files to avoid touching.
• Indexing quality affects Cascade output directly: Stale or incomplete indexes produce less accurate multi-file suggestions. Treat re-indexing as routine maintenance after major merges.

Indexing is the foundation. The full range of Windsurf capabilities that depend on project-wide context only perform at full strength when indexing is active and current.

How Do You Work Across Multiple Files and Folders with Cascade?

Once your project is indexed, Cascade can read any file in it without requiring you to open it first. It identifies relevant files based on your prompt and your @ mentions, then edits across them in a single run.

Multi-file operations are where Cascade earns most of its value. The workflow from prompt to accepted diff is straightforward once you know the pattern.

• @ mentions give Cascade precise scope: Referencing specific files, folders, functions, or symbols in a prompt narrows the search space and produces more targeted edits with fewer unnecessary changes.
• Cascade shows a plan before making changes: Before committing edits across multiple files, Cascade presents the planned changes. Review the diff across all affected files before accepting.
• Cascade can create new files in the right location: During a run, Cascade generates new components, modules, or tests in the correct directory within the project structure, not just edits to existing files.
• Multi-file refactors follow a reviewable workflow: Prompt, plan review, diff acceptance. Each step is visible. You are not committing to blind changes across the codebase.
• Break large tasks into smaller Cascade sessions: A single session modifying 20 files carries more risk than five sessions of four files each. Narrower prompts produce more predictable output and use credits more efficiently.

For concrete examples of what this looks like in practice, the guide to real projects built with Windsurf covers the kinds of codebases where multi-file Cascade sessions deliver the most value.

How Do You Manage Git and Version Control Inside Windsurf?

Windsurf's built-in Source Control panel handles staging, committing, branching, and diff review without requiring a terminal or external Git client. It is inherited from the VS Code architecture and requires no extension to activate.

The Git panel covers the operations that fill most sessions. Terminal access is still available for edge cases, but the panel handles the day-to-day flow well.

• The Source Control panel is in the activity bar: Changed files, staged files, and recent commit history are all visible here. No extension installation is required to access it.
• Stage individual files or hunks from the panel: Granular staging is supported. Write the commit message in the panel and push, all without touching the terminal.
• Branch management works from the Windsurf UI: Create, switch, and delete branches from the interface. Cascade is aware of the current branch state when generating suggestions.
• Inline diff view shows changes file by file: After a Cascade run that touched multiple files, the diff view shows additions and deletions line by line before you commit anything.
• Cascade can generate commit messages: Based on staged changes, Cascade can draft a commit message that describes what was changed and why, saving time on repetitive commit authoring.
• Use the terminal for complex Git operations: Rebases, cherry-picks, and multi-branch conflict resolution are often faster in the terminal. The panel covers common operations; the terminal handles the rest.

What Are the Best Practices for Large or Complex Projects in Windsurf?

Large codebases amplify both Cascade's strengths and its failure modes. Deliberate scoping, maintained indexing, and structured session planning keep Cascade accurate as project complexity grows.

The habits that matter most for large projects are not complicated. They are mostly about discipline in how you structure prompts and sessions.

• Scope prompts explicitly as the codebase grows: Vague prompts in large projects produce wide, unpredictable changes. Lead with the target file, function, or module to keep execution contained.
• Use .windsurfrules to set project-wide guardrails: Document naming conventions, restricted files, preferred patterns, and default libraries. This reduces correction cycles across sessions without requiring repeated manual instruction.
• Treat indexing as maintenance, not a one-time step: Re-index after large merges or major structural changes. Cascade's project model reflects the state of the codebase at the time of the last index, not the current state.
• Segment long tasks into sequential sessions: Review each diff before moving to the next step. A task split across five focused sessions is easier to validate than a single wide-scope run.
• Keep build output and dependencies out of the index: Node_modules, build artifacts, and test output folders inflate the index and dilute Cascade's awareness. Keep them gitignored and excluded.

For large repositories, it is worth reviewing Windsurf plan tiers and limits to understand where indexing capacity and Cascade credit ceilings sit on each plan before scaling up.

Conclusion

Windsurf's project model is intentionally minimal. A folder is a project, and the depth of AI assistance scales with how well that folder is structured, indexed, and scoped. The practices that matter most are not complex: keep indexing current, use @ mentions to scope Cascade, use .windsurfrules for persistent instructions, and break large tasks into reviewable sessions.

Developers who treat project setup as a one-time step get inconsistent results. Developers who treat it as an ongoing discipline get consistent ones. Open your current project in Windsurf, confirm codebase indexing is active in the Cascade panel, and create a .windsurfrules file with three standing instructions that apply to every session. That setup takes ten minutes and changes how every subsequent Cascade run performs.
