It assumes you can read code well enough to review a diff, which puts it closer to Cursor's audience than to a fully no-code tool. ## What do you need before you open Windsurf? Windsurf is an IDE with an AI agent built in, not a hidden-code app builder, so the starting assumptions are closer to Cursor's than to Lovable's. Before you start, you need a project (even a fresh, empty one Cascade can scaffold from scratch), a specific screen or feature scoped in a sentence, and enough comfort reading code to tell whether a generated file matches what you asked for. A free trial of Windsurf Pro runs two weeks with unlimited Tab completions and 100 prompt credits, which is enough to build and evaluate a first real prototype before deciding whether to subscribe. ## How do you actually build a prototype in Windsurf, step by step? 1. **Scope the feature in one sentence.** The same discipline that matters in any AI-assisted build matters here first: name the smallest version of the screen or flow that proves the idea. 2. **Describe it to Cascade in plain language.** Open Cascade and describe the feature, including what data it needs and what a user should be able to do. Cascade plans and executes across the files it needs to touch, not just one. 3. **Use the built-in preview immediately, not after the fact.** Windsurf's browser preview feeds the DOM, errors, and logs straight back to Cascade. Open it as soon as Cascade finishes a pass, rather than reading the diff cold. 4. **Let the build-preview-fix loop run for real bugs, not vague dissatisfaction.** If the preview shows an error or broken element, point Cascade at exactly what you see. This loop is what Windsurf is built around, and it works best with a specific symptom, not "this doesn't feel right." 5. **Review the diff for changes outside what you asked for.** The same discipline that applies in Cursor applies here: an agent fixing one thing can quietly restructure something adjacent. Read the full diff, not just the part you were watching. 6. **Test the actual user flow, not just the last screen touched.** Click through the scoped flow end to end before declaring the prototype done. 7. **Save a working checkpoint before your next ambitious request.** Commit or otherwise mark the last known-good state so a bad Cascade run has a clean point to roll back to. ## What should a PM do differently from a developer using Windsurf? A developer already has an instinct for reading a diff for unintended side effects; a PM needs to build that instinct deliberately. Use the built-in preview as your primary evidence, not the code itself: if the running screen behaves correctly and matches your one-sentence scope, that is a stronger signal for a non-developer than trying to read every changed line. When something breaks, describe the symptom you see in the preview (the exact error, the exact broken behavior), not your guess at the cause; Cascade's loop is built to consume that kind of concrete, visual feedback directly. A PM should also resist the urge to ask for multiple unrelated changes in one Cascade request. A developer might bundle a refactor with a new feature because they can predict the interaction; a PM cannot yet, so one request per feature keeps every change checkable against the one-sentence scope you wrote down first. ## Where do people get stuck building in Windsurf? - Describing a vague feeling ("this page feels off") instead of the specific error or element the preview is showing, which gives Cascade nothing concrete to fix. - Accepting a multi-file change because the one screen being watched looks right, without checking whether Cascade touched something else while implementing it. - Skipping the checkpoint habit, so a Cascade run that introduces a regression has no clean state to roll back to except starting the whole feature over. ## What does a good Cascade prompt actually look like? The build-preview-fix loop only works as well as the request that starts it. A vague first prompt like "build me a dashboard" gives Cascade nothing to check its own work against, so the preview step becomes guesswork about whether the result is right. A scoped prompt gives both of you something concrete to verify: "Build a dashboard page with three cards at the top showing total signups, active users, and churned users this month, and a table below listing the ten most recent signups with name, email, and signup date." Once Cascade builds that, the preview step has an obvious pass or fail: do the three numbers and the table actually appear, with real or placeholder data in the right shape? The same specificity matters when something breaks. "It's not working" gives Cascade no signal. "The signups card shows zero even though the table below lists ten real signups" points directly at the mismatch, and because Cascade's preview already has access to the same DOM and console output you are looking at, that specific description is usually enough for it to find the actual bug rather than guessing at one. ## When should you stop using Windsurf and move to something else? Windsurf is a strong fit while the prototype lives inside a codebase you or an engineer will directly maintain, and while the build-preview-fix loop is genuinely faster than reading and writing the code by hand. The honest limit is the same one that applies to any code-first AI tool: once nobody on the team can read a diff at all, a fully no-code builder like Lovable will get a stakeholder-ready demo in front of people faster, because it never requires anyone to evaluate code or a preview pane along the way. If the real goal has moved past a single prototype into a production system needing multi-agent orchestration and automation pipelines, that is a different scope than a single-agent, single-IDE workflow is built for. ## Who this is for, and who it is not for Windsurf fits builders and developers who want an AI-native coding environment with a tight feedback loop between writing code and seeing it run, similar to the audience Builders Camp's Building with Cursor bootcamp names for its own tool: people comfortable reading and writing code who want AI to speed up the parts of the workflow that are still slow. It also fits product-minded builders on the Vibe Coding Expert Track who are willing to look at real code as part of getting to a working prototype fast. It is a weaker fit for someone who has never opened a code editor and does not intend to start now. Builders Camp's platform-wide FAQ states that no coding skills are required generally, but that claim describes the Membership's non-technical bootcamps, not a code-first IDE like Windsurf. ## Learn the workflow that Windsurf and Cursor are both built around Windsurf and Cursor differ in interface, but the underlying discipline, explore before you build, plan before you execute, review every diff, is the same one Builders Camp's Building with Cursor bootcamp teaches directly, and it transfers to whichever AI-native IDE you end up using day to day. [See the Building with Cursor bootcamp](https://builderscamp.com/bootcamps/building-with-cursor?utm_source=guide&utm_medium=organic&utm_campaign=build-a-prototype-with-windsurf) If you want the Vibe Coding Expert Track's broader path instead of a single bootcamp, that track bundles this workflow alongside prototyping and shipping skills.

Cascade is Windsurf's built-in agent for autonomous, multi-file coding. Unlike a chat window that only answers questions, Cascade can run commands, edit across multiple files, and build a project end to end from one prompt, then use an agent-integrated browser to see the DOM, errors, and logs of what it just built. ### Do I need to know how to code to use Windsurf? Some familiarity helps more than it does with a fully no-code tool, because Windsurf is an IDE, not a hidden-code builder. You will see the files Cascade creates and edits. If you have never read a line of code before, expect a steeper start than Lovable, though Cascade's plain-language prompting still lowers the bar compared to hand-writing the code yourself. ### How does Windsurf's pricing work? Windsurf's Pro plan for individuals runs $20/month. A two-week Pro trial is available with unlimited Tab completions and 100 prompt credits. Teams pricing is $40 per user per month and adds analytics, role-based access control, zero data retention, and SSO. ### What is the build-preview-fix loop Windsurf is built around? Windsurf's built-in browser preview feeds the DOM, errors, and console logs straight back to Cascade, creating a tight loop: Cascade builds a screen, you preview it inside the IDE, Cascade sees the same errors and elements you do, and fixes follow without you copying error text back and forth manually. ### How is Windsurf different from Cursor for prototyping? Both are AI-native coding environments with an agent that edits multi-file projects, and Cursor's own comparison materials position the two directly against each other. The practical difference for most builders is the built-in preview loop: Windsurf leans harder into seeing and reacting to a running app inside the editor, while Cursor's Ask, Plan, Agent structure leans harder into an explicit plan-then-execute workflow. ### Can a Windsurf prototype be shown to a real customer? It can be demoed, but treat it the same way you would any AI-built prototype: proof that the workflow makes sense, not a production system. Authentication, data validation, and payment integration are separate, deliberate additions before real money or real customer data touches it. ### Is Windsurf included in the Builders Camp Membership? Windsurf is not one of the specific tools named in a Builders Camp bootcamp curriculum today; the closest match is Building with Cursor, which teaches the same category of AI-native coding workflow (explore, plan, execute) that a Windsurf-built prototype also depends on. ## Sources - [Windsurf: Plans and credit usage](https://docs.windsurf.com/windsurf/cascade/usage) - [Windsurf: Windsurf vs Cursor comparison](https://windsurf.com/compare/windsurf-vs-cursor) ## How this guide was made Researched from Builders Camp's bootcamp, track and masterclass material and the sources listed on this page, drafted with AI, and fact-checked against every source cited.
