The short version

  • Each has a real cost: CodeSandbox detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.; OWASP ZAP authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • They diverge on capability: CodeSandbox covers Instant sandboxes, OWASP ZAP covers Intercepting proxy.
  • Prices and features above were last checked on 30 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

CodeSandbox

  • Running AI agent-generated code safely in isolationnot OWASP ZAP
  • Prototyping and sharing web projects in-browsernot OWASP ZAP
  • Executing untrusted code for a code playground productnot OWASP ZAP
  • Using sandboxes as ephemeral CI/CD build environmentsnot OWASP ZAP

OWASP ZAP

  • Adding a baseline security scan to every application's pipeline where per-target commercial licensing would limit coverage to a handfulnot CodeSandbox
  • Manual penetration testing that needs an intercepting proxy, request replay and fuzzing without a paid licence per testernot CodeSandbox
  • Teaching developers what an attack against their own endpoint looks like, using a tool they can install themselvesnot CodeSandbox
  • Pre-release regression scanning of an internal application that would never justify a commercial DAST subscriptionnot CodeSandbox

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CodeSandbox

  • Detailed paid plan pricing was not published on the accessible pages, making cost comparison difficult.
  • Focus has shifted toward programmatic sandbox infrastructure, which may be less approachable for casual users just wanting a quick online editor.
  • Public sandboxes are visible to others by default, which is not ideal for proprietary code.

OWASP ZAP

  • Authenticated scanning of modern single-page applications is the hard part and ZAP makes you build it by hand: session handling, token refresh and login scripts are configured per application, and a misconfigured session means the scanner logs itself out and reports a clean result for pages it never reached.
  • There is no support contract in the product, so when a scan breaks the day before a release the escalation path is a GitHub issue and a community chat, which is not an answer that satisfies a delivery manager or an auditor who wants a named responsible party.
  • Active scanning sends genuine attack traffic, so it can create records, trigger emails, exhaust rate limits or destabilise a fragile environment, and pointing it at production without prior agreement produces an incident rather than a test result.
  • Output needs triage: passive rules generate large volumes of low-severity informational findings about headers and cookie flags that bury the few results that matter, and a team without someone tuning the rule set stops reading the report within a few sprints.
  • As a dynamic scanner it can only test what it can reach, so authorisation flaws between accounts, business logic abuse and anything behind an undiscovered endpoint go unreported, and a passing ZAP scan is evidence of nothing more than the absence of the classes of bug it looks for.

Questions people ask

Is CodeSandbox or OWASP ZAP better?
Neither clearly leads. CodeSandbox starts at Free and OWASP ZAP at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, CodeSandbox or OWASP ZAP?
CodeSandbox starts at Free and OWASP ZAP at Free.
Does CodeSandbox or OWASP ZAP run on more platforms?
CodeSandbox runs on web, api. OWASP ZAP runs on Desktop, Cli, Api.
Can I use CodeSandbox for free?
Both have a free tier, so you can try either at no cost before committing.
What is CodeSandbox best used for?
CodeSandbox is most often used for running ai agent-generated code safely in isolation, prototyping and sharing web projects in-browser, executing untrusted code for a code playground product, using sandboxes as ephemeral ci/cd build environments. Of those, running ai agent-generated code safely in isolation and prototyping and sharing web projects in-browser are not what OWASP ZAP is typically brought in for.
What can CodeSandbox do that OWASP ZAP cannot?
CodeSandbox covers Instant sandboxes, Programmatic sandbox API, Secure isolated execution, Browser-based editor. OWASP ZAP covers Intercepting proxy, Passive scanner, Active scanner, AJAX spider.

Answered from the vendors’ own pages

CodeSandbox: Does CodeSandbox offer a free tier?

Yes, CodeSandbox offers a free option available on the platform. Users can start for free.

Source
OWASP ZAP: Is it still called OWASP ZAP?

The project left OWASP in August 2024 and is now governed by the Software Security Project, with core development sponsored by Checkmarx. The tool is now just ZAP, though most existing documentation, courses and search results still use the OWASP name.

CodeSandbox: Where can I find CodeSandbox's pricing details?

CodeSandbox maintains a dedicated pricing page, but specific tier names, feature breakdowns, and costs are not displayed on the landing page.

Source
OWASP ZAP: Is it free for commercial use?

Yes. It is Apache 2.0 licensed, with no per-application, per-scan or per-user cost, and it can be used and modified commercially without a licence agreement.

OWASP ZAP: Can it replace a penetration test?

No. It automates checks for known vulnerability classes against endpoints it can reach. It does not reason about business logic, chain findings into an attack, or test authorisation between accounts, which is most of what a tester actually does.

OWASP ZAP: Does it run in CI?

Yes, through the official Docker images and the Automation Framework, which defines scan jobs in YAML so configuration lives in the repository. A baseline passive scan is the usual starting point because it is fast and non-intrusive.

OWASP ZAP: How does it compare to Burp Suite?

Burp Suite Professional is the more polished manual testing tool and has a stronger scanner and extension ecosystem, but it is licensed per tester and Burp Suite Enterprise per target. ZAP is the better fit where cost per target is the binding constraint; many teams use both.
