JavaScript and TypeScript can be fragile. MultiTool helps you test new Workers safely in the real world.
MultiTool tracks real user traffic and response behavior, automatically promoting what works and reverting what doesn’t.
Lightweight doesn’t mean low-stakes. MultiTool helps you ship focused, fast Workers without second-guessing the rollout.
MultiTool deploys your update to a subset of users.
MultiTool sends a small share of traffic to the new version while keeping the current one online.
The MultiTool agent uses response metrics from Cloudflare’s Observability API to monitor behavior. It doesn’t read logs or access any sensitive data.
If things look good, MultiTool finishes the rollout. If not, it rolls back, no manual intervention needed.
If your team pushes updates frequently, MultiTool helps you move quickly without sacrificing stability.
When low latency matters, Cloudflare delivers. MultiTool adds no runtime overhead, so your applications take full advantage of Cloudflare’s global CDN.
Skip the overhead of custom rollout tools. MultiTool handles networking and monitoring logic so you don’t have to.
