Comparing the security features of Lovable and Windsurf is easy to get wrong, because the two tools protect different things. Lovable is an app builder, so its security features are about the app it generates. Windsurf is a code editor, so its security features are mostly about the privacy of your code. Lining them up side by side only helps once you separate those two questions. Here is the honest comparison.
Short answer
Lovable and Windsurf secure different layers. Lovable, an AI app builder, has built-in scanning that checks generated code, dependencies, and database configuration for vulnerabilities before you deploy. Windsurf, an AI code editor, focuses on the privacy of your code through zero data retention and guarded agent actions, and leaves app security to the developer. Both offer zero data retention on paid plans, so on privacy they are close. Neither guarantees the shipped app is secure, by their own statements, so an independent check of the build stays your responsibility.
What you should know
- They protect different layers: Lovable secures the app it builds; Windsurf secures your code's privacy.
- Lovable scans the output: it flags keys, dependencies, and database misconfigurations before deploy.
- Windsurf leaves app security to you: it guards agent actions and data flow, not your app's vulnerabilities.
- Both offer zero data retention: on paid plans, your code is not retained or used for training.
- Neither guarantees a secure app: both say their controls do not ensure complete security.
What does each one's security features actually cover?
Different parts of the problem. Lovable's security features sit around the app it produces: it scans the generated code, the dependency tree, and the database configuration for known vulnerabilities and unsafe settings, and surfaces findings by severity in the normal build flow. Windsurf's security features sit around your development: zero data retention for your code, plus guarded agent actions and data-flow controls that reduce risks like prompt injection and secret leakage during coding. The table lines them up.
| Security area | Lovable | Windsurf |
|---|---|---|
| Type of tool | AI app builder, hosted | AI code editor |
| App vulnerability scanning | Built-in: code, dependencies, database config, before deploy | Left to the developer; advanced controls on Enterprise |
| Data retention | Zero data retention by default on Teams and Enterprise | Zero data retention by default on paid seats |
| Compliance posture | Managed infrastructure with security checks | SOC 2 Type II, FedRAMP High, HIPAA BAAs available |
| Guarantee of a secure app | No; scanners cannot ensure complete security | No; you implement the app's security |
How do they compare on data retention?
Closely. Both default to zero data retention on their paid tiers, meaning your prompts and code are not retained or used to train models, and where third-party AI providers are involved, contracts restrict training and retention. Windsurf adds formal compliance accreditations and offers HIPAA agreements, which matters if you operate in a regulated space. On the narrow question of whether the tool keeps your code, the two are comparable, and both are a reasonable choice for a privacy-conscious team. The practical difference within retention is reach: Windsurf extends zero data retention to all paid seats and backs it with formal audits, while Lovable applies it on its Teams and Enterprise tiers, so the plan you are on decides whether you actually have it. Data retention, though, is about protecting your code from the vendor, not about whether the app you build is secure.
Who actually scans the app for vulnerabilities?
Lovable, by default; Windsurf, not really. Lovable runs automated checks on the generated app and shows issues before deployment, which is a genuine advantage for a builder who would not otherwise run a scanner. Windsurf is an editor, so the security of the app you write in it depends on you, with more advanced controls reserved for Enterprise. That difference is the heart of the comparison: if you want a tool that flags app-level issues as part of building, Lovable does more out of the box, while Windsurf expects you to bring your own review and scanning pipeline. A useful way to read this is by what each tool optimizes for: Lovable is trying to ship a working app for a non-expert, so catching obvious security mistakes is part of that promise, while Windsurf is trying to be a fast, private editor for developers who already own their security process.
Which should you pick for security?
It depends on which problem you are solving. If you want built-in scanning of the app and you are building in a hosted environment, Lovable's automated checks are the stronger fit. If you want maximum control over your code's privacy and you run your own security pipeline, Windsurf's retention posture and compliance accreditations fit better. Neither choice removes your own responsibility, because both state that their features do not guarantee a secure app. So pick on the layer you need help with, then verify the result independently rather than treating either tool's security features as the final word. The choice is rarely either-or in practice, since many teams prototype in a builder and then move the code into an editor, in which case you inherit both the builder's output and the editor's privacy posture, and the verification step matters more rather than less.
What to watch out for
The trap is reading a tool's security features as a security guarantee. Lovable's scanner helps, but the company is explicit that it cannot ensure complete security, and Windsurf's privacy controls say nothing about whether your app has vulnerabilities. So a clean build in either tool is a starting point, not a sign-off. For the shipped result, a pre-submission scan such as PTKD.com (https://ptkd.com) reads the compiled APK, AAB, or IPA against OWASP MASVS independently of the builder, which catches what a builder's own checks or an editor's privacy settings do not cover. Use the tool's features during development, and an independent scan before you ship.
What to take away
- Lovable and Windsurf secure different layers: Lovable scans the app it builds, Windsurf protects your code's privacy.
- Both offer zero data retention on paid plans, so on privacy they are comparable, with Windsurf adding formal compliance accreditations.
- Lovable does more automated app scanning out of the box; Windsurf leaves app security to the developer.
- Neither guarantees a secure app, so verify the build independently with a pre-submission scan such as PTKD.com before submitting.
