Announced, not yet in effect

What this section prints is decided by the calendar, not by anything the vendor did. One record here carries a date after 2026-09-30. The vendor has announced it and it has not taken effect, so it is not part of the history below. On its own date a record here joins the Pricing Change Timeline, below.

Announced deprecated apiary.io effective 2026-10-31 high
Apiary reaches end of life on 2026-10-31, when Oracle stops the service and deletes remaining instances. Oracle announced it on 2025-10-28. The Free plan is the only one still open, so it ends with the product. Source ↗

Pricing Change Timeline

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.

We hold 7 more records filed under this category that are not counted above: entries the vendor has since reversed, our own index housekeeping, and corrections to earlier entries of our own. Read the full change log.

At-Risk Vendors

All 6 of the 41 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a source we cite, whose date falls in the last 180 days — or a standing condition, also cited, such as a free tier withdrawn or a product retired, which does not expire with time.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.

Stable Picks

All 13 of the 41 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.
