Sentio
Observability and analytics platform for smart contracts with custom processors.
Best for: Protocol engineering and data teams who want smart contract observability, custom indexing, and analytics in a single platform.Sentio is a full-stack observability platform for Web3 protocols. It combines on-chain data indexing with analytics dashboards, alerting, and debugging tools built specifically for protocol teams who need visibility into their smart contracts' behavior in production.
Developers write TypeScript processors (similar to subgraphs) that define how to index and transform on-chain events. Sentio handles the infrastructure: syncing, running processors, storing results, and serving data through dashboards and APIs. The developer experience is significantly better than The Graph's subgraph model, with faster iteration cycles and built-in testing tools.
Beyond basic indexing, Sentio offers metrics, logs, and traces for on-chain activity (concepts borrowed from traditional software observability, like Datadog but for smart contracts). Protocol teams can set up alerts for anomalous behavior, debug transaction failures, and monitor TVL, volume, and user activity in one place.
