64 MiB uncompressed on both plans.
Free plan
64 MiB uncompressed. There is no compressed-size limit.
Paid plan
64 MiB uncompressed.
What it means
Wrangler's `Total Upload` figure is the uncompressed size that counts. Large bundles also push against the 1 second startup limit.
What it does to a bill
Script size is not billed. Move assets to KV, R2, D1, or static assets instead of bundling them.
