Is Windsurf now Devin Desktop?
Yes. Cognition renamed Windsurf to Devin Desktop in 2026, preserving the editor foundation while making local and cloud agent management the primary workflow. Older tutorials still use the names Windsurf and Cascade, so this guide maps those terms to the current Devin Desktop product.
A Windsurf or Devin Desktop SaaS boilerplate gives those agents a tested application to extend: authentication, billing, organizations, email, typed APIs, documentation, and tests are already present before the agent starts building your product.
What changed from Windsurf to Devin Desktop?
The product remains a full code editor, but its center of gravity moved from one assistant panel toward coordinating agents.
| Earlier name or concept | Current role |
|---|---|
| Windsurf | The former product name; existing settings, extensions, and workflows carry into Devin Desktop |
| Cascade | The agent name found throughout older Windsurf workflows and documentation |
| Devin Local | Cognition's newer local coding agent inside the desktop product |
| Devin Cloud | An autonomous agent with its own cloud environment for longer delegated work |
| Agent Command Center | A shared view for planning, starting, and reviewing local and cloud tasks |
| Spaces | Shared context that groups sessions, work, files, and related artifacts |
If you previously used Windsurf, you can keep the same editor habits while adopting the newer local and cloud agent workflow. Current documentation may still use Cascade terminology for features that originated before the rename.
Why pair Devin Desktop with supastarter?
Running more agents does not solve missing architecture. It multiplies whatever architecture the repository already has, including inconsistencies.
supastarter gives every local or cloud agent the same base:
- Working SaaS infrastructure — authentication, subscriptions and purchases, organizations, email, storage, analytics, i18n, and admin tools
- A maintained
AGENTS.md— repository structure, conventions, commands, and finishing rules - Typed contracts — database, API, and UI boundaries that make incompatible changes easier to detect
- Modular packages — clear ownership for API, auth, database, mail, utilities, and the application
- Runnable checks — linting, type checks, and end-to-end tests for agent verification
- Markdown documentation — focused implementation context without copying entire web pages into a prompt
supastarter is available for Next.js, Nuxt, and TanStack Start as customizable source code with a one-time lifetime license.
How does Devin Desktop use AGENTS.md?
Devin Desktop's AGENTS.md support applies instructions according to the file's directory. A root file applies across the repository, while a file inside a package applies when the agent works under that package.
That makes a monorepo-friendly hierarchy possible:
AGENTS.md
apps/web/AGENTS.md
packages/api/AGENTS.md
packages/database/AGENTS.md
Use the root file for shared commands, naming, safety rules, and architecture. Add nested files only when a directory genuinely needs different instructions:
apps/web/AGENTS.mdcan describe server and client component boundaries.packages/api/AGENTS.mdcan require organization authorization on tenant-owned procedures.packages/database/AGENTS.mdcan define migration and schema conventions.
For more complex activation logic, Devin Desktop also supports rules. Keep the same fact in one place so agents do not receive contradictory instructions.
When should work run locally or in the cloud?
| Use a local agent when | Use Devin Cloud when |
|---|---|
| You are still shaping requirements | Acceptance criteria are already clear |
| The task needs rapid visual feedback | The task can run independently for longer |
| You want to approve commands interactively | The environment and checks are automated |
| You are debugging local state | The task is reproducible from the repository |
| You expect several short prompt iterations | You want a branch or pull request to review later |
A useful handoff pattern is: research and plan locally, write explicit acceptance criteria, delegate implementation in an isolated environment, then review the result locally. Do not delegate an ambiguous “build my SaaS” request and expect the cloud environment to supply the missing product decisions.
How do worktrees help with parallel SaaS development?
Devin Desktop supports Git worktrees so parallel sessions can edit isolated copies of the repository. Worktrees prevent agents from racing over the same working directory, but they do not prevent logical conflicts.
Divide work by stable boundaries:
- One agent researches the existing patterns and writes a plan.
- One agent owns a database and API change.
- A UI agent starts only after the API contract is agreed.
- A review agent checks the final diff without editing.
Avoid assigning two agents to independently design the same schema, authorization model, or billing rule. Git can merge text; it cannot decide which product model is correct.
What is a useful Devin Desktop SaaS prompt?
Read the root
AGENTS.mdand the instructions underpackages/api. Inspect the existing plan-gating helper. Add a file-upload allowance per subscription plan, enforce it for the active organization in the API, and show current usage plus an upgrade state in settings. Reuse the existing storage and billing abstractions. Do not edit checkout or webhook code. Add tests and run the repository checks before returning the diff.
For a cloud handoff, add environment-neutral acceptance criteria:
- The repository installs without interactive input.
- Tests do not rely on a developer's local data.
- Required environment variables are documented, not pasted into the issue.
- The final report lists commands run and anything that could not be verified.
Windsurf vs Cursor for SaaS development
Both are AI-first editor experiences, and both work better with the same agent-friendly foundation.
| Decision | Devin Desktop | Cursor |
|---|---|---|
| Primary emphasis | Coordinating local and cloud agents | Integrated editing and agent collaboration |
| Parallel work | Command center, cloud agents, and worktrees | Local and cloud agent workflows |
| Repository guidance | AGENTS.md, rules, and skills | AGENTS.md and Cursor rules |
| Best reason to choose | You want one surface for several agents | You prefer Cursor's editor and interaction model |
Choose based on workflow and team fit, not the model name advertised in a given month. Models and quotas change faster than your repository architecture.
Frequently Asked Questions
Is Windsurf discontinued?
The Windsurf editor evolved into Devin Desktop rather than disappearing. Existing editor workflows, extensions, settings, and plans were carried forward as part of the rename.
Does Devin Desktop read AGENTS.md?
Yes. It discovers root and nested AGENTS.md files and scopes nested instructions to their directories. supastarter includes a maintained root file in every starter kit.
Can Devin Cloud build a complete SaaS feature?
Yes, if the task is reproducible and has clear acceptance criteria. Authentication, payment, permission, and tenant-isolation changes still require careful human review.
Should I create separate branches for parallel agents?
Yes. Use isolated worktrees, branches, or cloud environments so each agent produces a reviewable diff without overwriting another session.
Does supastarter work with Cursor too?
Yes. The same typed codebase and repository instructions work with Cursor, Claude Code, Codex, Copilot, Cline, and Kiro.

Supastarter was extremely easy to get set up and deployed. I had a working project in just a few minutes!
Thank you Jonathan 🫡, @supastarter definitely saved us a couple of weeks of bootstrapping the new website!

We're a product development studio, and supastarter is the starting point for many of our SaaS projects. It saves us a ton of time so we can focus on what actually matters: building great products.

When we first set out to build Spyglasses we knew we needed an MVP before we even considered fundraising. That led us to researching starter kits. We looked at a dozen before settling on Supastarter. It had all the features we needed plus strong Cursor integration, which was critical to us. Thanks to Supastarter we saved 7+ months on our development estimates and even managed to pull some nice-to-haves into our initial launch.

As someone experienced with backend development but with limited frontend experience, I knew from the beginning that I would need to use a starter kit. There were a few options, and I decided to go with supastarter. It turned out to be the right call. Supastarter + AI coding + some common sense and guidance -> the project was shipped much faster than I anticipated. I would definitely use it again and not build things like auth, org and user management, and many other things all SaaS businesses need from scratch. Highly recommended!

I built the entire backend of my product, Phew AI Tab, using Supastarter, including the user system and payments and other api. Initially, I used Lemonsqueezy but switched to Stripe for specific reasons later on. I can't imagine how much time it would have taken without Supastarter; it only took a few days. What impressed me the most was the tech support from Supastarter. Even for issues not directly related to Supastarter, Jonathan provided timely and professional responses, which was a huge help and a great learning experience. Supastarter has grown even more powerful since I first used it. I highly recommend it to everyone starting their business, even up to a medium-sized team, as its comprehensive system can fully support growth. I'm so glad I chose Supastarter and I'm thankful for the team's support.

It really saved me a lot of time, I don't know how long it would have taken if I hadn't had supastarter. It's an amazing project, I loved the clean architecture and easy to take off and put on whatever you need, excellent job!
This supastarter has change my life of developer. With my CTO we are launching a startup and this boilerplate has really accelerate the development. As a developer of 10 years experience, I see that this has been built based on strong knowledge of the development covering all aspects, infrastructure, backend frontend with letting always the easiest way to customize. I would recommend it at 100% to a friend :) Well done Jonathan !
Grabbed my copy of the most supadupa #Nextjs #boilerplate back in December. The pace of releases and DX improvements is crazy. @jonathan_wilke gets it. After an exhaustive review this is the only #production ready #starter I found.
I'm using @supastarter by @jonathan_wilke ITS REALLY AMAZING 🔥

I recently encountered a minor issue in a piece of software I was using, which prompted me to report the problem on Discord. To my surprise and delight, the response from the development team was incredibly swift. Within just 10 minutes, not only had they addressed my concern, but they also committed the fix to GitHub. I was thoroughly impressed by the speed and efficiency of the team's action. It's rare to receive such prompt and effective support. This experience has certainly raised my expectations for customer service in the tech industry. Kudos to the team for their exemplary service!
Supastarter is truly an exceptional startup template! It boasts an impressive structure and exudes professionalism right from the start. The authentication options provided are top-notch, seamlessly integrated into the system. Additionally, the databases and other components are designed with efficiency and effectiveness in mind. The thoughtful consideration for serverless solutions is evident, showcasing a forward-thinking approach to modern development challenges. I adore the layout and highly recommend it as a startup template to others. It has saved me a tremendous amount of initial time in my project, proving to be an invaluable asset.
Supastarter has helped me launch a new product in record time - it gives you everything you need to get up and running quickly, and provides a framework to work on top of. Easily the best investment I've made in my SaaS product. Well done!

If I would need to start a newSaaS from scratch, I would definitely choose supastarter for it. I love the provided tools & libraries, the documentation is good and you get help in its Discord community.
Jonathan's Supastarter has taught me a lot. Great separation of concerns and code quality here. Learning from an actual codebase is far superior to watching the best video course ever.
Supastarter helped a ton with getting my project off the ground! You get authentication, prisma db connections, migrations, marketing and saas folders for your app, the damn complex payment subscription hooks setup. It's gonna save you weeks of having to slouch through your side project because Stripe hook doesn't work / connecting your data to your users is hard. At this price, Supastarter is unbeatable in helping you cut down on development time and speed 🚀
Supastarter was exactly what I was looking for to help spring board my first react SaaS web app and at a reasonable price point. The pre-built landing page, signup, database, light/dark theming setup gave me a guideline of good practices to follow and allowed me to get right to prototyping my ideas.

Supastarter is just awesome! It helped me go from scratch to authentication and payments integrated in minutes. Jonathan (the founder) is excellent and ready to support you every step of the way! I don't think there's a better way to kickstart your next SaaS!
Supastarter is truly a blessing for developers! It greatly simplifies the project creation process, helping us save a whole week of development time. This solution is not only efficient but also very suitable for team collaboration, allowing us to focus more on innovation and bringing our ideas to life.
