A public, stack-neutral daily tracker of web3 infrastructure providers — RPC, indexing, data APIs,
explorer APIs and specialized network services — with their free tiers, rate limits, access models and promos, plus the
opportunities (credits, grants, discounts, new services) and risks (shutdowns, deprecations, price rises) that move
between runs. Everything here is also published as machine-readable feeds.

Jito ShredStream shutdown date (Sept 5, 2026) has passed; docs still carry the stale notice and point to DoubleZero Edge (paid epoch seats, no free tier found)verified
Jito's lowlatencytxnfeed docs still display the 'will completely shut down on September 5, 2026' notice recommending migration to DoubleZero Edge; the date has passed, so treat ShredStream as shut down. The tx Send API (tips only, key-free) is unaffected.

Do: None unless TON coverage is planned. docs.chainstack.com/changelog
One run per day. Each run re-reads the official pricing, documentation and changelog pages of a
rotating slice of providers — roughly thirty per run, oldest last_verified first — sweeps the last 48
hours of provider news, and diffs the result against the stored state. A figure is marked verified only when it was
read from the provider's own page on that run; anything that could not be confirmed keeps an unverified marker
instead of being dropped, and the sources used are listed on every row and card.
Coverage is organized by reusable chain-family and capability vocabularies rather than a preferred
ecosystem. Named networks remain searchable in the underlying evidence, while prominent filters can evolve under the
published coverage policy without changing provider records or stable URLs.
