About Unprofane
Unprofane is a profanity and toxicity detection API designed to stop evasive tactics (leetspeak, look‑alike letters, creative spelling) while allowing benign edge cases like 'Scunthorpe'. It supports a full filter across 17 languages, is positioned as a drop‑in replacement for Perspective API, and offers predictable rate limits and billing for projects and prototypes.
Key Features
- Robust detection of leetspeak, look‑alike letters and creative spellings
- Multilingual filter covering 17 languages
- Drop‑in replacement for Perspective API
- Predictable plans and overage pricing (e.g., 25k checks/month for Hobby)
- Developer‑friendly API with rate limits (e.g., 120 req/min on Hobby)
