# TierGauge > Live SaaS pricing and migration hub for marketing and sales tools, refreshed weekly from each vendor's public pricing page. TierGauge tracks 37 marketing and sales tools across 21 categories. Every plan, price, limit, and feature is captured from the vendor's own pricing page on a weekly cron, with per-tool last_verified timestamps, and is published as both human-readable HTML and a CC BY 4.0 schema-pinned JSON API. Editorial posture is anonymous and disclosure-first: affiliate relationships are listed openly, and rankings are not influenced by them. ## Methodology and provenance - [Methodology](https://tiergauge.com/methodology): how pricing is captured, how tools are ranked, and the affiliate disclosure rules. - [About](https://tiergauge.com/about): editorial posture, contact (contact@tiergauge.com), and the data-freshness wedge. - [Freshness](https://tiergauge.com/freshness): per-tool last-verified dates, bucketed fresh / due / stale. - [Coverage](https://tiergauge.com/coverage): tools referenced as alternatives but not yet seeded, sorted by reference count. - [Changes](https://tiergauge.com/changes): chronological feed of detected anchor-price changes. - [Scrape runs](https://tiergauge.com/scrape-runs): per-tool most-recent scrape attempt, outcome, warnings. - [Status](https://tiergauge.com/status): build and pipeline health. ## Public data API (CC BY 4.0, free, no auth, CORS open) - [/api/tools.json](https://tiergauge.com/api/tools.json): full feed, all 37 tools with editorial fields, plans, prices, limits, features, source URLs, capture timestamps. - [/api/migrations.json](https://tiergauge.com/api/migrations.json): 37 curated migration guides as structured JSON. - [/api/posts.json](https://tiergauge.com/api/posts.json): every long-form post as structured JSON (title, summary, category, tags, published/last_updated, canonical URL).

Each answer cites a canonical tiergauge.com URL.
