PicPurify vs Sightengine

PicPurify is a real-time image moderation API for detecting and filtering inappropriate user-generated images. Its listed checks include porn, suggestive nudity, gore, money, weapons, drugs, hate symbols, obscene gestures, and QR codes. The API can also detect faces and return age-majority and gender classifications. It accepts JPG/JPEG, WEBP, PNG, BMP, TIFF, RAW, PDF, ICO, and GIF files, up to 4096×4096 pixels or 16 MB. The image API limit is five requests per second, which the maker says can be increased on request for legitimate reasons. Each task on an image uses one unit, so running multiple checks on the same image uses multiple units. Video moderation analyzes frames individually; its default interval is one frame per second, and charges depend on video size and frame interval. PicPurify says it can create a tailor-made model for specific detection needs. Integration examples are available for cURL, Python, Node.js, and PHP. The free plan includes 2,000 units with no time limit. Paid plans start at $19 per month.

Sightengine provides APIs to assess, filter, and moderate images, videos, and text. Its visual moderation checks categories including nudity, hate, violence, drugs, weapons, and self-harm. It also detects AI-generated images, videos, speech, and music, as well as deepfakes. Additional tools include OCR and QR moderation, image and video search, age estimation, liveness checks, and recapture detection. Image moderation thresholds and rules can be configured for different community policies. Developers can use API examples and SDKs for Curl, Python, PHP, and Node.js. Sightengine says it does not involve human moderators or share customer content with third parties. The Free plan costs nothing and has daily and monthly usage limits; it does not include video processing or live-stream support. Starter costs $29 a month for 10,000 operations, with additional operations at $0.002 each. Sightengine is cloud-deployed and lists API and web platforms.
