Summary

On September 4, 2026, Cloudflare removed the compressed Worker size limits (3 MB free, 10 MB paid) and now checks only the uncompressed bundle size, which is 64 MiB across all plans. Larger dependencies and heavier frameworks can now be deployed without hitting size restrictions.

What changed

Cloudflare stopped enforcing the compressed-size limits that previously rejected deploys over 3 MB (Free) or 10 MB (Paid). It now validates against a single 64 MiB uncompressed bundle limit on every plan; the gzip value is still shown for reference but is no longer a limit.

Why it matters

The old compressed caps forced teams to split bundles or trim dependencies, a real constraint when shipping AI SDKs, model clients, and agent frameworks to the edge. Raising the ceiling to 64 MiB lets heavier AI and agent workloads deploy directly on Workers without bundle gymnastics, strengthening Cloudflare's pitch as an edge runtime for AI apps.

Evidence excerpt

"Cloudflare now only checks the uncompressed size of your bundle, which is 64 MiB across all plans." The prior compressed limits of 3 MB (Free) and 10 MB (Paid) are removed; the gzip value is shown for reference but no longer enforced.
