Verdict

Neptune.ai does not currently have a free tier. We are not publishing a free-tier verdict for Google Vector Search 2.0. Tier "Pay-as-you-go" is usage-billed from the first request. When we last read the page we cite for Google Vector Search 2.0, on 2026-10-18, we found a change we could not reconcile with the terms we publish for it. The page we cite for Neptune.ai states no amount, tier or rate we can read when we last looked, on 2026-10-20. We are not comparing the two pricing histories.

A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. A badge carrying a date states the record it rests on; a badge with no date rests on no record in force.

ML experiment tracker, now shut down. After agreeing to be acquired by OpenAI, Neptune closed new sign-ups and trials on December 3, 2025, and set March 5, 2026 as the day its hosted app and API would be turned off and remaining hosted data deleted; on 2026-09-27 neptune.ai returned errors. Its free plan for individuals and researchers ended with the service. Neptune's migration guides cover Weights & Biases, Comet, MLflow and ZenML, among others.The page we cite for this offer states no amount, tier or rate we can read when we last looked, on 2026-10-20, so we cannot confirm these terms today.
