Source Makes
Edge-First Real

Source stack is designed for edge environments. Unlike cloud databases that require central coordination and constant connectivity, our databases, DefraDB, enables offline-first functionality, peer-to-peer sync, and local authority, making it ideal for edge and distributed environments, local-first software, edge AI, intermittently connected, or remote systems.

Source provides an edge-first data management stack with built-in offline functionality, peer-to-peer synchronization, verifiability, and flexible data governance. Developers can build resilient, responsive applications that don’t depend on a constant cloud connection. Synchronization conflicts are resolved using a specialized data structure: Conflict-Free Replicated Data Types (CRDT).

DefraDB is designed to be highly adaptable. It runs across various edge environments, from smartphones and industrial sensors to satellites and remote servers. DefraDB can be embedded natively onto chips, integrated into device software, or deployed within operating systems, depending on the use case and compute power.

Source’s stack enables peer-to-peer synchronization by allowing devices to securely share and merge data directly with each other without needing a centralized server. This creates a resilient, trustless network where each device holds only the data it needs and collaborates dynamically. Devices can passively sync to a secure global pubsub or actively to a specific target peer.

Source was designed for AI systems that need to think locally. Its cryptographically verifiable data structures ensure trust in training and inference pipelines, while built-in privacy controls keep sensitive data on-device. Support for federated learning, RAG (Retrieval-Augmented Generation), and offline vector search means you can deploy smaller and more specialized models where the data lives, with no reliance on centralized infrastructure.

Privacy, security, and governance aren’t add-ons at Source—they’re foundational. The stack supports end-to-end encryption, verifiable data integrity, and fine-grained access controls that travel with your data. Rather than routing everything through centralized intermediaries, Source enables secure, local-first enforcement of data policies across distributed environments.

Yes. Source is cloud-agnostic and interoperable by design. It can deploy natively or sync with major cloud platforms when needed, enabling hybrid edge-cloud deployments without forcing developers into vendor lock-in.

Source is a fit for any application where performance, resilience, and privacy matter. This includes smart cities, robotics, autonomous systems, industrial IoT, remote sensing, mobile apps, defense and space, and AI/ML systems.

Source’s DefradB uses cryptographically verifiable data structures and Merkle CRDTs (Conflict-Free Replicated Data Types) to ensure every change is traceable, mergeable, and tamper-evident. Conflicts resolve automatically or via developer-defined logic—no need for a central authority. This makes it possible to synchronize data seamlessly across distributed devices, even in offline or low-connectivity environments.

Source provides developers with a suite of tools, including APIs and a CLI, designed for seamless integration into existing workflows. We offer language-specific support through our GraphQL interface, which enables the generation of bindings and SDKs for various programming languages. Additionally, WASM builds are available for direct embedding within applications.

Yes. Source’s DefraDB natively supports vector embeddings and retrieval-augmented generation (RAG) pipelines. It's built to power AI workloads at the edge, enabling local search, recommendation, and inference systems with full privacy and verifiability.

Source’s database, DefraDB, is built to run at the edge. Its architecture is optimized for moderate-low-power, resource-constrained devices—whether you're embedding it in a mobile app, running it on a sensor, or syncing across a mesh network. The stack compiles down to lightweight binaries, so it performs with minimal overhead while preserving full functionality, even offline.

Source is being used by pioneering developers and organizations building local-first software, mobile apps, autonomous systems, remote sensing networks, and AI/ML applications at the edge. Industries from distributed energy, telecommunication, and satellite to industrial IoT are adopting Source today.
