What is 1CAPTCHA?

We are building a modern, developer‑first captcha service that works seamlessly with any programming language and any type of application — web, mobile, desktop, or server‑side backends.

Our mission is to provide the latest validation techniques (behavioral analysis, challenge‑response, and machine‑learning detection) while keeping integration dead simple via REST APIs and SDKs.

• Multi‑language SDKs (PHP, Python, Node, Go, Java)
• API‑first design – use with any stack
• Server‑side verification (no client‑side bypass)
• Low latency & high availability
• Accessible and privacy‑friendly
• Continuous updates against evolving threats

Whether you run a small blog or a large enterprise, 1CAPTCHA adapts to your needs. We’re launching soon — stay tuned.
