Packing always-awake Durable Objects into Containers to cut duration cost

Robert Chandler (@bertie_ai) says keeping 1,000 Durable Objects awake costs $4,050 a month, and that he ran the same 1,000 for $22 a month by pooling them inside Containers with workerd; the thread covers why, the durability trade-off and when real Durable Objects are still cheaper. The figures are the author’s calculations, not a bill.

Cloudflare free plan from scratch: which services bill on overage, and what to set up first

李天才 (@Lniosytest) re-walks a popular Cloudflare beginner tutorial (domains, email routing, R2, Workers AI) against the October 2026 docs, prompted by the $10,811 Durable Object alarm bill, and adds a table of what happens on overage plus a pre-flight list for avoiding a runaway bill.

RetainDB: a reported $36k bill from a queue loop with 81 users.

Reddit user alameenswe, building RetainDB on Workers, KV, Durable Objects and Queues, reports a Cloudflare bill of about $36k for one month with 81 users; the post body says $35,000. He attributes it to a queue consumer that re-queued async writes, 12 unbatched Durable Object writes per memory write and a kv.list() authentication fallback.

Lion Brain: a Durable Object alarm loop from an AI-coding bug wrote about 250 million rows, roughly $210.

Replying in another user's Community thread, bennygoldstein says a bug written by an AI coding tool made a Durable Object alarm in their Lion Brain app re-index the same data every few seconds on October 10 and 11, 2026, writing about 250 million rows and costing roughly $210 in overage on Workers Paid. He says he only found out from the budget alert email, which never pauses anything, and that he opened a billing case asking for a one-time courtesy credit and a real hard spending cap.
