Arcjet has moved its JavaScript SDK out of beta with the launch of v1.0, signaling a stable, production-ready API that is intended to reduce maintenance risk for development teams building security-critical systems. After more than two years of public iteration, including an alpha release in 2023 and a beta in early 2025, the company is committing to API stability in a JavaScript ecosystem where rapid dependency turnover can turn minor upgrades into costly migration projects.
CEO David Mytton emphasized that the v1.0 release confirms the SDK has already been proven under real production workloads, with thousands of developers deploying it across 500+ applications and relying on it as core security infrastructure. Over the alpha and beta period Arcjet introduced only three breaking changes, maintained backward compatibility where possible, and adopted a predictable monthly release cadence to limit version churn, while underpinning the SDK with redundant systems, uptime monitoring, and operational investment, positioning Arcjet’s platform as a long-term, low-friction security layer embedded directly into customer codebases.
