Every record we hold is listed here, newest first. A record is never removed from this list, so a vendor named here stays named here whatever its verdict does afterwards.
On November 5, 2026, Ably moved to pricing on monthly active users (MAUs). The Free package now has a cap of 500 MAUs a month, which the free plan did not have before. It still allows 6M messages a month and 500 messages a second, and its concurrent connections rose from 200 to 500. Paid plans are now Pro and Business, from $29 and $349 a month for 1,000 MAUs billed annually. Accounts already on Ably's resource-based pricing keep their terms. Source ↗

HiveMQ no longer lets anyone create Serverless clusters and retires the Serverless plan (Free and Pay As You Go) on 2026-12-31. Existing clusters run until then. After that date, clients cannot connect and HiveMQ permanently deletes the clusters and their data. Source ↗
Meta resumed charging for WhatsApp service messages on 2026-10-01. Each business phone number gets 1,000 free service messages a month, and Meta charges from the 1,001st at the recipient market's service rate. Service messages had been free without a monthly limit since 2024-11-01. The same day, Meta began charging for utility templates sent inside an open customer service window, at the recipient market's utility rate; they had been free since 2025-07-01. Source ↗

Svix cut its Free plan from 200 to 50 messages a second and from 30-day to 7-day payload retention, and moved the 99.9% uptime SLA to a new Basic plan from $20 a month. Free's 50,000 messages a month, beyond which messages were billed, now reads "Up to 50k messages per month". The pricing page changed between the Internet Archive's 2026-09-14 capture and our read on 2026-09-27. Source ↗
model changeCloudflare Queuesdiscovered 2026-09-05 · effective date unknownhigh
The free tier now offers 10,000 operations/day, and the paid tier offers 1,000,000 operations/month. Message retention on the free tier is 24 hours (non-configurable), while the paid tier offers 4 days default, configurable up to 14 days. The pricing model is now based on operations (64KB chunks of data written, read, or deleted) with additional costs per million operations beyond the included allowance. Unconfirmed. We could not check this change against an archived copy of Cloudflare Queues's page, so it does not count toward the rating.Source ↗
OneSignal limited mobile push and in-app messaging on its Free plan to organizations with up to 1,000 monthly active users, from September 1, 2026 for new customers and October 1, 2026 for existing customers. Above the limit, mobile push and in-app messages pause until the account upgrades; web push and email keep working under the existing limits. Mobile push had been unlimited on Free. Source ↗

At-Risk Vendors
All 4 of the 28 vendors we list in this category that carry one. A vendor is named here for as long as a demotion is in force against it: a one-off pricing event, recorded against a source we cite, whose date falls in the last 180 days — or a standing condition, also cited, such as a product retired or a free tier withdrawn and not restored, which does not expire with time. A demotion can lift with nothing about the vendor having changed, and that happens on the day the vendor's newest qualifying event passes 180 days.
All 14 of the 28 vendors we list in this category that qualify, not a selection of them. A vendor is named here for as long as no demotion is in force against it and we hold no change record for it dated in the last 90 days — any record, including ones the timeline above does not count. A vendor can join this section on a day we recorded nothing about it, when the later of those two clocks runs out: 90 days after its newest record, or the day the demotion against it lapses. It leaves on the day we file a new record, or the day we can no longer vouch for the terms we list.
