How Filter8 compares

Wordlists, retiring APIs, enterprise suites, hosted ML classifiers, chat SDKs — here's an honest look at where Filter8 fits, and where it doesn't. Pick your current tool and see the difference.

vs Perspective RETIRING

Perspective is being shut down. Filter8 is the deterministic replacement — a verdict, not a score; sub-millisecond; nothing retained after the response.

vs bad-words WORDLIST

The npm package censors "classic" and misses "@ss". Filter8 is the deterministic upgrade you graduate to when users show up.

vs CleanSpeak ENTERPRISE SUITE

A capable moderation suite. Filter8 is the API-first, self-serve, transparently priced alternative — evaluate it before you talk to anyone.

vs Azure Content Safety HOSTED ML

Per-1,000-record pricing is a tax on every message. Filter8 is flat-cost and deterministic — sub-millisecond, nothing retained after the response.

vs AWS Guardrails HOSTED ML

Per-text-unit billing, doubled when you check input and output. Filter8 is flat-cost and deterministic — sub-millisecond, nothing retained after the response.

vs Hive ML MODERATION

Strong at visual moderation. For high-volume text, Filter8 is deterministic and flat-cost — replayable, sub-millisecond, nothing retained after the response.

vs Sightengine MODERATION API

Per-operation ML across media and text. For text, Filter8 is flat-cost, deterministic, PII-aware, and keeps nothing after the response.

vs OpenAI FREE CLASSIFIER

Free, but it's a network hop to OpenAI's policy. Filter8 runs your policy in microseconds — deterministic.

vs Stream & Sendbird CHAT SDKs

Bundled moderation is locked to their SDK. Filter8 is a portable, deterministic filter for your whole stack — any backend.

vs Community Sift ENTERPRISE SUITE

An enterprise moderation platform. Filter8 is the API-first, self-serve, transparently priced alternative — evaluate it before you talk to anyone.

vs Bodyguard.ai HOSTED SAAS

Hosted contextual moderation. Filter8 is the deterministic alternative — replayable, sub-millisecond, flat-cost on the text hot path.

vs WebPurify HOSTED SAAS

A hosted moderation service with image + human review. Filter8 is the deterministic text engine — replayable, sub-millisecond, flat-cost.

Read the text comparison →
vs Google Cloud NL HOSTED ML

Per-character-block billing (the paid Cloud classifier, not the retiring Perspective). Filter8 is flat-cost, deterministic, and keeps nothing after the response.

vs Tisane NLP API

A multilingual NLP abuse-detection API. Filter8 is the deterministic text engine — replayable, sub-millisecond, flat-cost on the hot path.

THE THROUGHLINE

Whatever you're replacing, the difference is the same three things.

01 · Catches the dodge
26 evasion classes folded back before matching — and it doesn't censor "Scunthorpe."
02 · Never guesses
A pure function of (bundle, input) — same answer every time, replayable and explainable.
03 · Cheap enough to leave on
Flat compute cost, sub-millisecond, and nothing retained after the response.
