What PowerSync does
PowerSync is a sync engine developed by Journey Mobile, Inc., a privately held US company headquartered in Denver. The product links backend databases—Postgres, MongoDB, MySQL, SQL Server, and Convex—with in-app SQLite via change data capture and a proprietary bucket-based sync protocol, enabling offline-first, real-time reactive mobile and web applications. The platform consists of two components: a backend service (available as PowerSync Cloud, an open-source self-hosted edition, and an enterprise self-hosted edition) that streams partial data to clients using Sync Streams for dynamic partitioning, and a family of client SDKs spanning JavaScript/Web, React Native, Flutter, Kotlin Multiplatform, Swift, .NET, Rust, Tauri, Capacitor, and Node.js. The SDKs manage local SQLite persistence, consistency via checkpoint systems, incremental and differential watch queries for reactive UI updates, and a bi-directional upload queue for syncing writes back to the backend.
PowerSync targets mobile and web application developers building offline-capable, local-first software, with a secondary segment of enterprise organizations (e.g., 7-Eleven, Halliburton, Allianz PNB Life, Christian Louboutin) requiring scalable, compliant sync infrastructure. The company monetizes through a three-tier model: a free Cloud tier for developers, usage-based Cloud pricing billed by synced operations and active users, and quote-based Enterprise Self-Hosted contracts with dedicated support and compliance features (HIPAA, SOC 2, GDPR, CCPA). Distribution is fully product-led and community-driven: the product is available via self-serve signup, seven package registries (npm, pub.dev, Maven Central, NuGet, crates.io, Swift Package Manager, GitHub Packages), and an active developer community of 2K+ Discord members and 1.9K GitHub stars.

PowerSync product offering
Product offeringCore offering
PowerSync is a sync engine that links backend databases (Postgres, MongoDB, MySQL, SQL Server, Convex) with in-app SQLite, enabling real-time, offline-first application functionality. It consists of a backend service that replicates data via change data capture and bucket-based sync with checkpoints, plus client SDKs that manage local persistence, reactivity, and write-back to the backend. The product supports partial sync via Sync Streams, JWT-based authentication, conflict resolution, and horizontal scaling to tens of thousands of concurrent clients.
Product overview
PowerSync is a sync engine consisting of two primary components: a backend service (available as PowerSync Cloud, PowerSync Open Edition, or PowerSync Enterprise Self-Hosted Edition) that syncs data from Postgres, MongoDB, MySQL, SQL Server, or Convex databases to client-side SQLite, and a family of client SDKs for Flutter/Dart, JavaScript/Web, React Native, Kotlin Multiplatform, Swift, .NET, Rust, Tauri, Capacitor, and Node.js. The product enables offline-first, real-time reactive applications with bi-directional sync, partial data syncing via Sync Streams, JWT-based authentication, and conflict resolution. Developer tooling includes a web Dashboard, CLI, and Sync Diagnostics Client.

PowerSync competitors and assessment
Company assessmentBroad incumbents
- Firebase: Google's mobile and web BaaS platform with Firestore, Realtime Database, and Authentication. Firebase is the incumbent mobile sync solution with broad adoption and tight Google Cloud integration; PowerSync competes for the same use case but differentiates with open-source flexibility and backend-database choice.
- AWS AppSync / Amplify DataStore: AWS-managed GraphQL and offline data sync services for mobile and web apps. As part of the AWS ecosystem, AppSync/DataStore competes with PowerSync for the same offline-first workload, offering deeper integration with the AWS data layer at the cost of cloud lock-in.
Direct peers
- RxDB: An open-source reactive NoSQL database for JavaScript apps with built-in replication plugins for CouchDB, GraphQL, and others. RxDB competes for the offline-first app developer market, primarily in the JavaScript/web ecosystem.
- Supabase: Supabase is an open-source BaaS offering Postgres, Auth, and realtime, with its own offline/sync roadmap and storage layer. It is a direct peer in the developer backend stack where PowerSync positions as the offline-first sync layer on top of Supabase, and increasingly competes with it on the sync feature itself.
- Replicache: A local-first sync framework for web and React apps that pairs a client-side store with a transactional backend. Replicache targets the same developer pain points around offline UX and stateful reactivity, with a strong focus on React.
- ElectricSQL: Open-source local-first sync layer that syncs Postgres into local SQLite/Postgres clients. ElectricSQL is the most direct technical peer to PowerSync, addressing the same local-first sync problem with a similar open-source distribution model.
- Convex: A reactive backend-as-a-service with its own sync engine, TypeScript schema, and real-time subscriptions. Convex targets the same developer persona building stateful reactive apps and now sits among PowerSync's supported source databases, making it both a partner and a competitor.
Emerging players
- Hasura: GraphQL data access layer that exposes backend databases (Postgres, SQL Server, MongoDB) as real-time APIs. Hasura is adjacent to PowerSync — both sit between backend databases and client apps — but Hasura focuses on the API/GraphQL layer rather than the client-side SQLite sync engine.
- PocketBase: An open-source single-file backend with auth, database, and real-time subscriptions, popular for small-to-medium apps. PocketBase overlaps with PowerSync at the small/medium-app end of the market where developers want a simpler all-in-one backend with offline support.
- InstantDB: A newer local-first backend offering sync, queries, and permissions as a managed service for web and mobile apps. InstantDB targets the same local-first developer persona as PowerSync, with a higher-level managed-API approach that competes for the same PLG funnel.
