Edge Functions execution duration limit set to 300 seconds
Vercel is implementing a new 300-second execution duration limit for Edge Functions starting March 1st, 2025. This change standardizes behavior for streaming responses and post-response tasks, replacing the previous unpredictable timeout behavior based on system resources.
This changelog entry is historical. Edge Functions are deprecated for new projects. Use with the Node.js runtime and . Use for request-time routing before a response completes.Note:Vercel FunctionsFluid computeRouting Middleware
Starting on March 1st, 2025, we will begin the rollout of a new execution duration limit of 300 seconds for using the Edge runtime.Vercel Functions
Previously, functions using the Edge Runtime had no fixed timeout for streaming responses, leading to unpredictable behavior based on system resources and traffic. With this update, functions using the Edge Runtime will consistently allow streaming responses for up to 300 seconds, including post-response tasks like .waitUntil()
