Alchemy Subgraphs (formerly Satsuma) is a blockchain indexing platform with drop-in support for hosted subgraphs.


Web3 engineering teams rely on subgraphs to quickly build custom APIs. However, they typically run into a few issues that cost engineering time.

  • With the Hosted Service:

    • Downtime.

    • Data lag.

    • Slow reindexes.

    • Slow queries.

    • Lack of direct support.

  • With the Decentralized Network:

    • Extra engineering effort.

    • High, unpredictable query costs.

    • Lack of indexing certainty.

    • Lack of direct support.

  • With self-hosting:

    • Extra engineering effort to setup.

    • Mental burden for engineers to handle maintenance & issues.
