Commercial transition
Previous stateWorker deploys were rejected when the compressed bundle exceeded 3 MB on Free or 10 MB on Paid plans.
→New stateCloudflare no longer enforces the compressed-size limits and instead checks one 64 MiB uncompressed bundle limit across Free and Paid plans.
Who is affected
Developers deploying Cloudflare Workers whose bundles approach the former compressed limits or the new 64 MiB uncompressed limit.
Action required
Measure the Total Upload value with a Wrangler dry run and keep the uncompressed bundle at or below 64 MiB; treat the gzip value as informational.
Evidence boundary
This changes the Workers bundle-upload size measurement and limit only. It does not change request-body limits, runtime memory, CPU limits, pricing or plan entitlements beyond the stated bundle cap; the old compressed and new uncompressed measures are not directly comparable.
Timeline
- Unified bundle limit available
Cloudflare removed the compressed 3 MB and 10 MB checks and began enforcing 64 MiB uncompressed across all plans.
