Pricing is a time series, not a screenshot

TierDrift exists because the most important context on a pricing page is usually missing: what changed, when it changed, and how the plan structure drifted.

The gap

SaaS vendors continuously change price points, billing models, included usage, and plan boundaries. Search results tend to show only the current page, while buyers, analysts, founders, and AI systems need a citable history.

The product thesis

TierDrift starts with a deliberately small public baseline and compounds an asset that cannot be recreated retroactively: weekly, append-only pricing observations, moving toward daily coverage. The defensive value comes from elapsed time, consistent normalization, and evidence quality.

What comes next

This release has no accounts and no payment processing. After the public dataset earns search and citation traffic, commercial layers can add alerts, category indexes, exports, watchlists, and research workflows without hiding the source record.
