Code audit, any author

Know what is really in that plugin.

We read the code, whoever wrote it: a marketplace plugin, a freelancer's build, AI-generated PHP, or the theme that came with a site you just bought. You get a written report on what it does, what it risks and what to fix.

What we check

How do you check a WordPress plugin for malware or backdoors?

We read the code line by line, then run it on a staging copy to watch what it actually does, not just what its description says.

Security

Nonces and capability checks, sanitized input, escaped output, obfuscated code, and any hidden call to a remote server (a common sign of a backdoor).

Code quality

Whether it follows WordPress conventions, uses hooks correctly, and avoids editing core files or other plugins directly.

Compatibility and performance

PHP 8.1 to 8.5 compatibility, deprecated function calls, slow queries, and conflicts with plugins you already run.

Licensing and update path

Whether the copy is a legitimate, licensed original (nulled or pirated copies are a common malware vector) and whether it will still get updates.

How it works

How does a plugin or theme audit work?

The same process for one plugin, a whole inherited site, or a shortlist you are deciding between.

  1. Send us the code

    The plugin or theme file, a link to it, or access to the site it is already installed on.

  2. Get a written report and a fixed price

    What it does, what it risks, and what a fix costs, before any work starts.

  3. We fix what needs fixing

    Only if you want us to. Some audits end with 'it's fine', some end with a list of changes, tested on staging before they ship.

  4. Decide with confidence

    Install it, reject it, or fix it, backed by a report instead of a guess.

Honest comparison

Trust the vendor, or an independent audit?

Most WordPress plugins are fine as they are. An audit earns its cost in specific situations, not every install.

What clients say

We ship 100+ products of our own, so we read code the way we would our own

  • My setup was a nightmare: multiple tools, deep integrations, custom configurations that required real back-and-forth. Most vendors would've pointed me to a knowledge base article and disappeared. Not Wbcom Designs. Every time I reached out, they responded fast, understood the problem immediately, and delivered custom code snippets that actually solved my issues. This is the standard every software company should be held to.

Questions about auditing plugin and theme code

Is this plugin safe to install?
We read the code and tell you plainly: safe as is, safe with fixes, or not recommended, with the specific reasons in a written report. We also run it on a staging copy to see what it actually does.
How do I check a WordPress plugin for malware or backdoors?
Look for obfuscated code, calls to unfamiliar remote domains, functions like eval() or base64_decode() used to hide logic, and unusually broad file-write permissions. Confirming this reliably usually needs a manual read, which is what this audit does.
I just bought a site. Can you audit everything that is already installed?
Yes. We inventory every plugin and the theme, flag anything abandoned, nulled or risky, and tell you what to replace before it becomes a problem.
Do you audit free plugins too?
Yes, free and paid, WordPress.org or elsewhere. Price is unaffected by where the code came from.
How much does an audit cost?
You get a written report and a fixed price before any work starts, based on how much code there is to read.
Do you write the fixes too?
If you want us to. Some clients just want the report to decide with; others ask us to fix what we found, tested on staging before it goes live.
