AWS Lambda vs Cloudflare Workers
AWS Lambda and Cloudflare Workers cannot be scored on the same axes — one of them does not publish a rate for everything serverless functions bills on.

Monthly cost for three real workloads
The rate cards applied to identical usage. This is where the winner changes.
| Workload | AWS Lambda | Cloudflare Workers | Cheaper |
|---|---|---|---|
| Side projectA personal site or small app with modest traffic, a few gigabytes of assets, and one small always-on process. | — | $5.00 | Not comparable |
| Growing SaaSA funded product serving a few thousand daily users, with an image-heavy frontend and two application servers. | — | $5.00 | Not comparable |
| Media-heavy siteA publisher or video product where delivery dominates the bill and compute is almost an afterthought. | — | $5.00 | Not comparable |
Workload definitions are identical on every comparison page, so figures here can be read against any other pair in the same category.
What each one is for
AWS Lambda
by Amazon Web Services
The service that created the category, billed on requests plus memory-time. The permanent free tier absorbs a surprising amount of production traffic before a bill appears.
Free tier: 1M requests and 400,000 GB-seconds per month, always free
Cloudflare Workers
by Cloudflare
V8 isolates rather than containers, which removes cold starts and caps memory at 128 MB. Billed on requests and CPU time actually consumed, not wall-clock duration.
Free tier: 100,000 requests per day, always free
Common questions
- Is AWS Lambda or Cloudflare Workers cheaper in 2026?
- Neither can be scored across all three workloads, because at least one of them does not publish a rate for every axis this category bills on.
- Which has the better free tier, AWS Lambda or Cloudflare Workers?
- Both publish one. AWS Lambda: 1M requests and 400,000 GB-seconds per month, always free. Cloudflare Workers: 100,000 requests per day, always free.
- What do these estimates not include?
- Committed-use and reserved discounts, regional price variation, per-request API charges, support plans, and minimum retention periods. All of those move real invoices, sometimes by a lot. These figures compare published list prices for the same workload, which is the comparison the rate cards alone cannot give you.
