CaptchaLa is a bot and abuse prevention platform offering risk-based CAPTCHA, fraud detection, and content moderation APIs with SDKs for web and mobile apps.
CaptchaLa is a bot and abuse prevention platform built around a server-side risk-scoring engine: it only shows an interactive CAPTCHA when a request looks suspicious, reducing friction for legitimate users. Challenges can be displayed in several modes (popup, floating widget, button-bound, or inline), and server-issued tokens with anti-replay checks verify each response.
Integration is SDK-based, with official SDKs for Web, Android, iOS/macOS, Flutter, and Electron, plus a WordPress plugin and a REST API for server-side verification. The docs highlight a 5-minute quickstart and a public MIT-licensed demo at demo-v1.captcha.la.
Beyond CAPTCHA, CaptchaLa offers two related products: a bot/fraud-detection service that returns a per-visit human/bot verdict for traffic and ad-fraud protection, and a content moderation API for text and image screening.
Plans are priced by monthly verification volume, from a free tier for solo developers up to enterprise plans with SLAs, priority support, and multi-app management for large-scale production traffic.
