About the ledger
StackWatch is an editorial data product for developer-tool pricing and AI-industry news. It keeps source context, timestamps, billing details, and extraction uncertainty visible.
Each tracked official pricing page is fetched by the nightly pipeline. Third-party price summaries are not used as source evidence.
The fetched HTML is stored under a dated vendor snapshot path before structured extraction is published.
Plans, prices, units, and limits become structured records. Ambiguity remains visible as an extraction caveat instead of being silently resolved.
Ten curated industry accounts and official sources for a ten-company AI coverage set provide discovery signals only.
A candidate must resolve to a separate, non-social source. AI then normalizes the facts and merges duplicate coverage.
Cards use an original headline and summary with the external link, never raw post text, social URLs, handles, or source identities.
Extraction status
Verified with 5 caveats across the current records. Each affected dossier lists its exact warning text.A verified timestamp marks the latest successful structured record from that vendor's official pricing source. Verified clean means no extraction warnings were stored. Verified with caveats means the record remains usable, but one or more unresolved conditions are disclosed in the dossier. Verification is not a promise that a vendor will honor a price.
Monthly prices and annual-billed monthly equivalents occupy separate fields. Free, usage based, not listed, and contact or custom offers remain distinct. Category ledgers group source currencies before sorting numeric entry offers; they do not convert currencies or rank quality.
Later comparisons distinguish increases, decreases, newly listed numeric prices, amounts no longer listed, and unchanged baseline states. Teal denotes verified or decreased values, coral denotes increases, amber denotes caveats or newly listed states, and neutral text denotes a baseline.
StackWatch currently links directly to official vendor pages without referral tracking. If customer referral links are added later, each one will be marked as sponsored. Affiliate availability never changes data, coverage, category ordering, or comparison facts.
Vendor pages can be incomplete, region-specific, or changed between checks. Every dossier links back to the official source and exposes its archived snapshot as inert plain text, with a SHA-256 digest, so a published figure can be traced. The next successful extraction can correct the structured record while retaining detected price history. News summaries can also be incomplete or become outdated; readers should consult the linked external source. A link supplies context, not endorsement.
