Stellar Indexers

Mercury

Mercury is a cost-effective and efficient indexing service that specialized both on Soroban and Stellar "Classic/Vanilla" indexing. Mercury also offers a cloud service for deploying advanced network-synced programs that need to work with the Network's data.

Decentrio

Decentrio provides infrastructure services including RPC and high-performance transaction/event indexing for Soroban decentralized applications.

BlockEden.xyz

Stellar Soroban Indexer and GraphQL.

Public Node

A nonprofit organization that supports and brings a trusted and meaningful public voice to open and inclusive blockchain networks.

Nirvana Labs

Nirvana will build a public RPC endpoint supporting Stellar's Soroban upgrade on a proprietary web3 cloud off AWS & GCP.

SubQuery

SubQuery is a leading blockchain data indexer that provides developers with fast, flexible, universal, and decentralized APIs for web3 projects, supporting over 200 ecosystems including Stellar, Ethereum, and Polkadot.

PipeOps

PipeOps is a cloud Infrastructure product that allows for devs to deploy, automate, manage and scale their cloud Operations easily.

StreamingFast

StreamingFast brings Firehose and Substreams indexing to Stellar, integrating it into The Graph's decentralized indexing network. Substreams-powered Subgraphs enable high-throughput, parallelized extraction and streaming of Stellar/Soroban ledger and event data as composable data pipelines for subgraph-like access to onchain data.

Space and Time

Space and Time is a verifiable data warehouse and indexer for Stellar/Soroban, integrated with SDF to power data-driven smart contracts. It indexes onchain ledger data, lets developers join it with offchain datasets, and uses Proof of SQL zero-knowledge proofs to verify query results for reserves/NAV proofs, accounting, audits, and compliance.

Obsrvr

Obsrvr provides production-ready Stellar RPC node infrastructure including Stellar/Soroban RPC endpoints, Horizon API access with RPC archive support, and Flow programmable data pipelines for real-time event streaming and indexing. Lets builders read and submit transactions on mainnet and testnet. SCF-funded and listed on the official developers.stellar.org RPC providers page.

ZettaBlock

ZettaBlock is an institutional-grade Web3 data indexer and analytics platform integrated with Stellar (SDF partner). It indexes Stellar/Soroban on-chain data and auto-generates custom GraphQL and REST APIs from SQL queries, with historical and real-time data plus private off-chain data joins for building data-driven dapps without managing your own indexing infrastructure.

Stellar Indexer

Indexing service for Stellar smart-contract data — live contract state through a single endpoint, with per-protocol extensions (Blend, Reflector, Axis Markets; more in progress). TypeScript SDK for Node, Deno and Bun published on JSR as @stellar-indexer/stellar-indexer-sdk. In token-gated beta. By earrietadev (Creit-Tech, the xBull team).

Hubble

Hubble is SDF's open-source, read-only BigQuery data warehouse providing a complete historical record of the Stellar network for large-scale analytics. Powered by the stellar-etl pipeline, it extracts and transforms ledger, transaction, operation, and event data into BigQuery for SQL querying, aggregation, and network-trend analysis.

Lightsail Network (Quasar)

Quasar by Lightsail Network is a Stellar RPC and data services provider offering a real-time mainnet Stellar RPC node (rpc.lightsail.network), a full archive RPC for historical queries, and a Galexie data lake. Provides mainnet RPC archive access for builders reading and submitting transactions. Listed on the official developers.stellar.org RPC providers page; Lightsail also maintains the Java Stellar SDK.

Alchemy

Alchemy is an enterprise-grade Web3 developer platform live on Stellar and a tier-1 validator on the network (per Alchemy's own announcement, mid-2026). Two products for builders: managed Stellar/Soroban JSON-RPC (mainnet + testnet endpoints, Horizon access, dedicated nodes; listed on the official developers.stellar.org RPC providers page) and the Stellar Data API — indexed transfer history, account balances, and NFT holdings across native, Stellar Classic, and Soroban assets, so builders can query portfolio-style data without running their own indexer.
