ContentGuard — The Indonesian Content Firewall

Regex Mutation Engine

Unlike basic string replacement, our engine generates thousands of permutations for every keyword. It understands that s10t, s.l.o.t, and sl0t are the same word.

/g[a4@]c[o0]r/i /j[u\w]d[i1]/i

Indonesia First

Tuned specifically for the Indonesian market. Pre-loaded with local gambling terms, hate speech, and slang.

Zero configuration needed

Laravel Ready

Includes a Facade and Service Provider. Just install and use `ContentGuard::check()`.

No External Dependencies

Developer Experience

Drop it into your
Controller logic.

Whether you are building a Laravel monolith or a native PHP script, ContentGuard fits right in. No complex configuration files or external API calls required.

Frequently Asked Questions

Common questions about performance and compatibility.

Does this work with PHP 8.x?

Yes, ContentGuard is fully compatible with PHP 8.0, 8.1, and 8.2. It utilizes modern PHP features for optimal performance.

Can I add my own bad words?

Absolutely. If you are using Laravel, you can publish the configuration file and add an array of custom keywords to the blocklist.

How heavy is the regex processing?

We've optimized the engine to be lightweight. The regex patterns are compiled efficiently, resulting in negligible overhead (< 2ms) for typical comment lengths.
