Can You Sell Code Written with Cursor AI? Commercial Rights (2026)

Not gonna lie or something like that, just switched from GitHub Copilot to Cursor for my freelance development work. My whole workflow now relies on Cursor's AI features (Tab completion, Composer, Chat). Questions:

• Do I own code written/generated through Cursor?
• Any license contamination risks like with Copilot?
• Cursor Pro vs Business — any IP differences?
• Can I use Cursor for commercial client projects?

Cursor's terms are straightforward on ownership:

Code ownership:

• "You retain all rights to code you write using Cursor" — clear and simple
• Applies to all plan tiers (Free, Pro, Business)
• No revenue restrictions or usage caps on commercial deployment

vs GitHub Copilot:

• Similar ownership terms — both grant you full ownership
• Cursor uses multiple AI models (GPT-4, Claude) rather than Copilot's dedicated Codex model
• Copilot Business has Microsoft IP indemnity; Cursor does not offer indemnification
• Both have potential license contamination from training data

License contamination risk:

• Cursor routes through third-party models (OpenAI, Anthropic) that were trained on public code
• Same theoretical risk as Copilot — generated code could match GPL/copyleft-licensed code
• No built-in duplicate detection filter like Copilot offers

We use Cursor Business across our 15-person engineering team. A few practical notes:

• Cursor Business adds privacy mode — your code isn't used for model training
• We pair Cursor with FOSSA for license compliance scanning in our CI/CD pipeline
• In 8 months of heavy use, we've had zero license contamination flags
• The practical risk is extremely low for typical web/SaaS development

The bigger concern for enterprises is the data privacy angle. Cursor sends your code to third-party AI providers (OpenAI, Anthropic) for processing. Make sure your data handling requirements allow this.

@jurys_out_12 The lack of IP indemnification concerns me. If a client's codebase gets flagged for license issues from Cursor-generated code or whatever, am I liable?

@asking_for_myself_25 As the developer, you're responsible for the code you deliver to clients regardless of which tools you use. Cursor's terms explicitly disclaim liability for IP issues in generated code.

Practical protection:

• Your freelance contract should limit your liability for third-party IP claims
• E&O (errors and omissions) insurance can cover this — it's affordable for freelancers
• Run license scanning on your deliverables before handoff
• The actual risk of someone pursuing a GPL infringement claim over an AI-suggested code snippet is currently theoretical

If IP indemnity is critical (enterprise clients), GitHub Copilot Business/Enterprise with Microsoft's indemnification may be the safer choice despite Cursor's superior UX.

Solo dev perspective: I built and launched 3 SaaS products entirely using Cursor Pro ($20/mo). All generating revenue. Zero legal issues. The ownership terms are clear — your code is yours.

For indie devs and small teams, the IP indemnity question is mostly academic. Nobody is going to sue you over a Cursor-suggested function. The license scanning pipeline approach is overkill for most of us. Just use the tool and build your product.

Resurrecting this thread because I'm in a mess. Our dev agency signed a client contract that says no AI tools on the project "without prior written consent." Half the team uses Cursor daily like everyone else in 2026. Client's CTO saw an editor screenshot in a standup recording and now they're threatening to withhold the final invoice, about $38k, for breach.

The code passed all their reviews and acceptance tests months ago. Are we actually exposed here?

Oof. Notice that this isn't really the ownership question this thread started with, it's a straight contract question. They wrote a condition, you agreed to it, and the work happened outside it. The interesting part is whether the remedy for that is "keep all the money for work we accepted" which feels off given they took delivery and it passed acceptance.

General information, not legal advice. Start with the exact clause text. "No AI tools" clauses vary enormously: some ban AI-GENERATED deliverables, some ban feeding client materials into third-party AI services (usually a confidentiality concern), and some ban any AI-assisted tooling outright. Which one you have changes both the breach analysis and the conversation. A confidentiality-driven clause, for example, turns on whether client code or data actually left your environment and what the tool's data settings were, which is something you may be able to answer well.

On the money: acceptance of conforming deliverables matters, and a total forfeiture for a process violation on accepted work is an aggressive position for them to take. This is one where the specific wording, your acceptance records, and the tool's data-handling settings really decide it, so get the documents in front of a lawyer before anyone sends angry emails. A calm technical writeup of what the tool did and didn't access is often the thing that de-escalates it.

Update: pulled the contract. The clause bans use of "generative AI tools in the performance of the Services" without consent, so broader than just deliverables, not great for us. But we CAN show the workspace ran in privacy mode with training disabled and no client secrets in prompts. Meeting with their CTO Thursday, bringing a written rundown of the setup instead of arguing about the clause. Will report back.

Lesson for everyone reading along: raise the tooling question BEFORE signing. I added a short clause to my own MSA saying I may use AI coding assistants with privacy modes enabled, client materials stay out of training, and I remain responsible for all deliverables. In two years exactly one client pushed back, and that conversation took ten minutes because it happened up front instead of after a screenshot.
