LocalMod vs WebPurify

LocalMod is a free content moderation API for text and images that runs on Linux within a self-hosted setup. The project says it can run offline, keeping user data within the user's infrastructure. Text classifiers check for PII, toxicity, prompt injection, spam, and NSFW text; the PII classifier covers emails, phone numbers, Social Security numbers, and credit card numbers. Image moderation detects explicit or adult images. API endpoints support single and batch text analysis, PII redaction, and image analysis from a URL or uploaded file. The README documents Python use, running an API server, and Docker deployment, and includes an example Discord bot for real-time text and image moderation with auto-delete, timeouts, and logging. Offline operation requires downloading the models once and setting LOCALMOD_OFFLINE=1; the documented download is about 3.5 GB and includes the image model. The README recommends a GPU for production workloads and lists CPU and GPU latency estimates by classifier. LocalMod is MIT licensed.

WebPurify provides content moderation services for text, images, user-generated video, live streams, metaverse experiences, and generative AI content. Its profanity filter supports 15 languages and custom block and allow lists; offensive intent detection is available on custom plans. Image review can use automated AI, human moderators, or a hybrid workflow. Text moderation connects through WordPress, Drupal, and Joomla plugins, or through APIs for web and mobile applications. Text plans include a 14-day free trial with full feature access and no credit card required; image moderation offers 100 free photo moderations without a contract or card. Monthly text options list Plugins at $5 a month, Standard at $15 a month, and Enterprise at $50 a month. These plans allow one, two, and four simultaneous requests per license, respectively. Image options include WebPurify AIM at free, billed per image, and Live Moderation at $0.02, paid once, billed per photo. WebPurify says reviewed content is not retained on its servers and customer data is not stored.
