Updated logging limits for Vercel Functions

Craig AndrewsSoftware Engineer, Infrastructure

The runtime log limits for Vercel Functions have been increased, allowing for significantly larger log entries. These updates replace the previous 4KB-per-line restriction, and they are now live for all projects.

The runtime log limits are now:

  • Log line size: Up to 256KB per log line.

  • Log line count: Up to 256 individual log lines per request.

  • Total log size per request: Up to 1MB (sum of all log lines in a single request).
