Requests, Durable Object traffic and stored data are multiplied. Cron is not: a schedule runs the same number of times whatever your traffic.

Compute only: Cloudflare vs Lambda vs Cloud Run

Workers bill CPU time, so waiting on fetch(), KV or D1 is free. Lambda and Cloud Run bill wall time multiplied by memory. Storage and databases are left out on all three.

Service	Per month
Cloudflare Workers	$5.00 Source checked 2026-09-23
AWS Lambda	$0.00 Source checked 2026-09-23
Google Cloud Run	$0.00 Source checked 2026-09-23

Assumptions

Requests and compute time only; storage and databases are not included.
Cloudflare: the $5.00 base plus Workers requests and CPU time.
128 MB of memory and 80 ms of wall time per invocation, cron runs included.
Lambda: x86, us-east-1, after the monthly free allowance.
Cloud Run: request-based billing, Tier 1, 80 concurrent requests per 1 vCPU instance, after the monthly free allowance.

About this tool

Is Cloudflare Workers free enough?

Usually the daily request count is not what breaks first. The Free plan allows 100,000 Worker requests a day, but also only 10 ms of CPU time and 50 subrequests per invocation, 1,000 KV writes a day and 100,000 D1 rows written a day. Describe what one request and one cron run do, and every quota gets a headroom multiple: ×4.0 means four times today's traffic still fits, ×0.8 means the limit is already hit.

What the Workers Paid plan costs

Paid starts at $5 a month and includes 10,000,000 requests and 30,000,000 CPU milliseconds; after that it is $0.30 per million requests and $0.02 per million CPU ms. KV, D1, R2 and Durable Objects each bring their own included amount and overage rate, and the bill is broken into lines so you can see which one the money actually comes from.

Growth, and why cron is different

The growth table multiplies requests, Durable Object traffic and stored data by 2 and 10. Cron Triggers stay as they are: a job that runs every minute runs 1,440 times a day whether you have ten users or ten thousand. That is why the first wall can move as you grow. A cron-heavy Worker tends to run out of D1 or KV writes first, a traffic-heavy one runs out of requests or CPU time.

Compared with AWS Lambda and Cloud Run

The side-by-side covers compute only: requests plus compute time, no storage and no databases. Workers bill CPU time, so waiting on fetch(), KV or D1 costs nothing. Lambda and Cloud Run bill wall time multiplied by the memory you allocate. A 200 ms request that spends 5 ms on the CPU is priced very differently on each, and the assumptions under the table spell out exactly what was compared.

Frequently asked questions

What are the D1 free tier limits?

On the Free plan D1 allows 5,000,000 rows read and 100,000 rows written per day, and 5 GB of storage in total. Rows read counts every row a query scans, not just the rows it returns, so a missing index shows up here first. On Paid, 25,000,000,000 rows read and 50,000,000 rows written a month are included, then $0.001 per million rows read and $1.00 per million rows written.

What is the Workers subrequest limit?

50 subrequests per invocation on Free and 10,000 on Paid. A cron run is an invocation too, so a job that checks 60 URLs in one run is already over the Free limit. This calculator counts your fetch() calls against it; Cloudflare's limits page gives calls to KV, D1 and R2 a separate, higher allowance.

Do Cron Triggers count as requests?

Yes. Cloudflare's own pricing example bills an hourly Cron Trigger as 720 requests a month, so cron runs are added to the request count here. The Free plan allows 5 Cron Triggers per account and Paid allows 250, and on Free each run gets the same 10 ms of CPU time as a request.

Can I use Durable Objects on the Free plan?

Yes, Durable Objects with SQLite storage are available on Free, with 100,000 requests and 13,000 GB-s of duration a day. Duration is billed as if every object holds 128 MB, so 13,000 GB-s is about 104,000 seconds of objects being active per day. On Paid, 1,000,000 requests and 400,000 GB-s a month are included, then $0.15 per million requests and $12.50 per million GB-s.

Why is Lambda so much cheaper or dearer than Workers here?

Because they meter different things. Workers charge for CPU time. Lambda charges $0.20 per million requests and $0.0000166667 per GB-second of wall time after 1,000,000 free requests and 400,000 GB-seconds a month (x86, us-east-1). Cloud Run request-based billing charges per vCPU-second and GiB-second while requests are in flight, and several concurrent requests share one instance. A Worker that mostly waits on the network is cheap on Cloudflare and comparatively expensive elsewhere.

Where do these numbers come from?

Every quota and rate was read off the official Cloudflare, AWS and Google Cloud pricing and limits pages and is stored with its source link and the date it was checked. A daily job re-reads those pages and flags any figure whose wording changed; nothing updates by itself. Open the source next to a number to see the page and date. Figures checked more than 30 days ago are marked as possibly out of date.
