Data Indexers
Data indexers solve a different job than RPC providers. Use them when a product needs queryable contract history, normalized wallet data, realtime database sync, or analytics exports that raw node calls do not provide cleanly.

Shortlist visual
The shortlist is useful only when every product is judged against the same workload, docs, and launch risk.
Start with the data shape
Compare fit against the same selection criteria.
Use official docs for supported products, chains, API surfaces, and production limits before choosing.
Selection criteria
Confirm the requirement against current docs, pricing, or support terms before it enters the shortlist. Use it as a data indexers shortlist checkpoint.
Compare the same field across every product so the review does not drift into vendor-specific language. Use it as a data indexers shortlist checkpoint.
Name the team owner who will keep this check current after launch or renewal. Use it as a data indexers shortlist checkpoint.

Shortlist
| Product | Best For | Pricing | Free Tier | Networks / rails | Disclosure |
|---|---|---|---|---|---|
| The Graph | Apps and analytics teams that need indexed smart-contract data without building every data pipeline themselves. | Network and hosted-service costs depend on query, indexing, and product usage. | Public docs and developer access are available; production costs depend on usage path. | Ethereum, Base, Arbitrum, Optimism | Organic |
| Goldsky | Teams that want managed indexing and realtime data movement into their own databases or pipelines. | Plan and usage pricing depends on indexing, streaming, RPC, and support needs. | Public docs and trial paths may be available; production terms depend on plan. | Base, Ethereum, Optimism, Arbitrum | Organic |
| GoldRush | Wallets, portfolio tools, tax tools, and dashboards that need normalized blockchain data through REST APIs. | API pricing depends on usage, plan, and product surface. | Developer access and public docs are available; production limits depend on plan. | Base, Ethereum, Solana, Polygon | Organic |
Buying record
The shortlist should help a team explain why a product made the list, which sources were checked, and what still needs a test before anyone signs or migrates.

FAQ
Use an indexer when the app needs queryable contract history, normalized wallet or token data, realtime sync, exports, or analytics views that raw RPC calls make expensive or fragile.
No. Indexers and data APIs can reduce custom data work, but apps still need RPC or provider infrastructure for direct chain reads, writes, and transaction status checks.
