Platform features and external scanners provide different evidence. Compare the documented checks, configuration, and inputs for each project. SimplyScan offers public URL observations and separate code-input workflows; neither platform feedback nor an external scan establishes complete application security.

Compare the Checks Available to Your Project

Security features vary by product, plan, integration, and configuration. Review current documentation and test the application’s actual controls.

The comparisons below distinguish documented platform features from the additional review an application needs.

What Does SimplyScan Check?

SimplyScan’s URL scan checks supported public content and responses. Its GitHub repository and MCP selected-file workflows analyze other inputs. None of these verifies every CSRF defense, private policy, or authenticated operation.

Use findings alongside direct review of these risks:

  • Secrets: Privileged credentials in public artifacts.
  • Database access: Privileges and RLS policies, tested with relevant roles.
  • Authentication and authorization: Protected operations and trusted identity handling.
  • Injection: Untrusted data reaching queries, commands, or eval().
  • XSS: Untrusted content reaching dangerouslySetInnerHTML or innerHTML.
  • CSRF and headers: Request integrity and deployed browser policies.
  • Configuration: CORS policy, debug output, and exposed files.
  • Architecture: Secret boundaries, rate controls, and server-side access decisions.
  • Resource use: Expensive operations and concurrency behavior.
  • AI integrations: Prompt injection, tool permissions, and secret handling.

This is a review checklist, not a claim that the URL scan detects every item.

SimplyScan provides GitHub repository scanning, supported fix prompts, and remediation guidance. Review proposed changes and test them; prompts do not guarantee a correct patch or a fixed repair time.

What Does Lovable's Security Checker Cover?

Lovable’s security documentation describes database and dependency checks, plus a Deep scan for application-code issues such as authorization, unsafe input, endpoints, and secrets. Optional integrations can add coverage.

Review the findings and scope: A pattern involving dangerouslySetInnerHTML requires investigation of the data path and output handling. Do not infer that Lovable lacks injection or endpoint analysis simply because another tool also reports those categories.

Use Lovable’s findings alongside deployed checks and application-specific tests. A separate Lovable guide discusses configuration and review; no category count establishes complete coverage.

Does Cursor Have a Built-In Security Scanner?

Cursor is a code editor, not a deployment platform.

Cursor offers Bugbot code review. Review the configured repository workflow and the findings it produces. Privacy settings govern data handling; they do not verify the security of generated code.

Assess deployed responses, database permissions, and authenticated behavior separately from code-review findings. Do not assume a code-review tool has no ability to flag secrets or injection patterns.

Use Cursor review feedback alongside tests of the actual application. See the Cursor security checklist.

What Do Bolt.new's Security Audits Cover?

For a Bolt project, inspect the security findings and database settings available in the current project interface. Verify the scope of the checks you run.

Review project controls: Inspect authentication, database permissions, secrets, and deployed configuration. Run the checks available for that project and investigate their evidence.

Test application behavior: Use suitable accounts to test permitted and denied operations. A lack of findings does not prove that injection, access-control, or secret-handling defenses are complete.

Use project feedback alongside an application security checklist and tests. See the Bolt guide for additional review topics.

What Does Replit's Scanner (Semgrep + HoundDog) Cover?

Replit’s security overview documents static analysis, dependency analysis, and sensitive-data detection, including Semgrep and HoundDog integrations.

Inspect the actual findings and proposed repairs. Analysis tools and AI-assisted fixes still require review and testing against the application’s requirements.

Test deployed behavior, authorization, and configuration in addition to inspecting source findings. Use the selected tool’s documented scope to identify remaining coverage gaps.

Use the Replit security guide alongside the project’s current security features and application-specific tests.

Does Windsurf Have a Built-In Security Scanner?

For a Windsurf project, distinguish editor controls, AI data handling, review tools, and tests run against the application.

Review the data-handling terms and settings for the features you use. A local editor or local command execution does not establish that AI context stays on the machine.

Windsurf documents Cascade hooks that can run configured checks around agent actions. Review hook commands and their scope; a hook is not automatically a vulnerability scanner.

Use the Windsurf security guide to organize code, configuration, and deployed-behavior review. Generated changes still need testing.

A Security Review Checklist

Choose review tasks for the application’s requirements:

Scan for Secrets

Inspect .env values, source, and built artifacts such as dist for exposed privileged credentials. Public project identifiers require different handling from secrets.

Verify Database Access

For Supabase, review table privileges, RLS policies, and bypass roles, then test permitted and denied operations.

Check Headers

Use a security headers tool to inspect returned CSP and HSTS values, then test the intended browser behavior.

Audit Endpoints

Enforce authentication where required and authorize protected operations on the server. Intentionally public endpoints do not all need a session token.

Test for Injection

Use parameterized queries and appropriate safe APIs for the relevant interpreter; validate inputs and handle output in its context.

Monitor Uptime

Use uptime monitoring for supported availability observations. An outage or slow response alone does not establish a DoS attack or its cause.

Why SimplyScan Is Different

1. Public URL Inputs

SimplyScan’s URL workflow accepts publicly reachable deployed sites without repository access. Target accessibility and supported checks limit coverage.

2. Deployed and Code Inputs

SimplyScan inspects supported public content and responses in its URL scan. Separate GitHub repository and MCP selected-file workflows provide source inputs. Review deployment configuration and application behavior alongside both.

3. Investigate Supported Findings

Review evidence and coverage before choosing a repair. Use code review and authenticated tests for behavior outside the scan’s supported observations.

How to Use SimplyScan with Your Platform

Combine useful platform findings with deployed checks and application-specific tests. A SimplyScan result informs a release decision; it does not prove that production is safe.

  • Lovable projects: Review database, dependency, and code findings alongside deployed behavior.
  • Replit projects: Review analysis results and proposed fixes, then test affected behavior.
  • Cursor or Windsurf projects: Combine code review and configured checks with deployed and authenticated application tests.

FAQ

Do I need SimplyScan if Lovable already has a Security Checker?

Compare the coverage you need. Lovable documents database, dependency, and application-code checks, with optional integrations for additional testing. SimplyScan provides supported public URL observations. Use relevant findings alongside application-specific tests; neither tool guarantees complete security.

Which AI coding platform has the best built-in security scanning?

This article does not establish a ranking. Compare current documented coverage, configuration, and findings with the application’s requirements. Replit documents static and dependency analysis, but product names alone do not establish which tool fits every project.

Can Cursor or Windsurf scan my code for vulnerabilities?

Cursor offers Bugbot code review, and Windsurf supports workflows such as configured Cascade hooks. Review the actual features and checks you use. Editor privacy or infrastructure assurance does not establish that generated code is secure.

What is the difference between scanning source code and scanning a deployed app?

Source scanning analyzes supplied code. Deployed checks inspect supported content and responses from the running application. Each has coverage limits; neither automatically verifies every database policy, secret-handling path, or authenticated operation.

How much does SimplyScan cost compared to platform security features?

Compare current plan terms and supported coverage. SimplyScan offers a free URL scan across eight site-health dimensions and a Pro report option with supported fix prompts. A manual penetration test has a different scope and is not an equivalent product based on price.

Does any platform scanner check for prompt injection or AI security risks?

Check each product’s current documented tests and inputs. Distinguish platform-agent protections from checks of your own AI integration. Review prompt handling, tool permissions, and exposed credentials directly; no general scanner result proves resistance to every prompt-injection attempt.

Pro report costs $14.99 one-time.
