Arcjet helps developers protect their apps in just a few lines of code. Bot detection. Rate limiting. Email validation. Attack protection. Data redaction. By embedding security at the application layer, Arcjet helps teams protect their apps from common attacks and allows them to ship fast with confidence. without slowing down development or introducing infrastructure complexity. Unlike traditional security tools that rely on agents or proxies, Arcjet operates at the application level, letting developers enforce precise, contextual rules directly in their code. Teams can add protections in minutes, tune rules in code and get the security signals directly in code. For customers, this means fewer false positives, better threat visibility and security that evolves as quickly as your application does without extra infrastructure or operational overhead. Arcjet currently provides SDKs for JavaScript and TypeScript including Node.js, Bun, Deno, Next.js, Remix, SvelteKit, Astro, React Router, Nuxt, and others.
