Free Tier Details
Managed Valkey cache, cluster and pub/sub, formerly a serverless cache with a free tier.

Data correction - Momento's free allowance, the first 5 million operations each month, ended between 2025-08-03 and 2025-11-10, not in 2026. Our 2026-09-05 re-read compared the page with our own listing text, which still gave the 5 GB a month Momento offered until 2024. Source ↗
Before: Dated 2026-09-05, between archive copies of 2026-06-18 and 2026-09-16, with the free tier given as 5 GB of data transfer a month
After: Dated between archive copies of 2025-08-03, which offers the first 5 million operations free each month, and 2025-11-10, which offers nothing free
Momento ended the free allowance on its pay-as-you-go plan, the first 5 million operations each month. By 2025-11-10 its pricing page offered Flex from $5,000 a month and a legacy pay-as-you-go plan at $1 per 1 million operations, with nothing free. Source ↗
Before: Pay only for what you use: first 5 million operations free each month, then $1.00 per million operations

How Momento compares against every one of the 3 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.

Recompute today's order yourself. The order above is a permutation seeded only on the UTC date and the query key — no vendor name, slug, id or offer field is an input. The list above is every one of the 3 entries in that order, not a prefix of it. The algorithm is published, so anyone can reproduce this page's order without asking us.
We do not push notifications. Every change we record is readable the moment it lands, and the JSON answer carries an ETag — send it back as If-None-Match and an unchanged answer costs one 304.
