In their own words
Ditto
Ditto is a distributed database and Edge SDK for applications that must operate when networks are unreliable or unavailable. Its embedded database lets devices read and write offline, then synchronize through Bluetooth Low Energy, peer-to-peer Wi‑Fi, or a local area network without internet access or extra hardware. Devices using the SDK can form wireless mesh networks for real-time sharing in bandwidth-constrained environments. Ditto automatically resolves conflicts between peers and with the cloud when available. The platform supports Android, iOS, Windows, and Linux, with SDK languages including Swift, Kotlin, JavaScript, C#, C++, Rust, Flutter, and React Native. The Free plan costs nothing and includes 10 cloud device connections, 2GB storage, 5GB transfer, limited support, and no SLA.
Firestore
Firestore is a fully managed, serverless document database for building AI, web, and mobile applications. It stores flexible JSON data and supports vector search, full-text search, geospatial queries, and ACID transactions on JSON or BSON-compatible documents. Client SDKs for Android, iOS, and web provide real-time updates and automatic syncing for offline access. Firestore can replicate data across multiple regions with strong consistency; multi-region deployments have a stated 99.999% SLA-backed availability. Integrations named for generative AI application work include Google AI Studio, remote MCP, LangChain, and LlamaIndex. Identity controls connect with Cloud IAM, Cloud Identity Platform, and Firebase Authentication. Data is encrypted before it is written to disk, with customer-managed keys available through Cloud KMS. The free quota applies to one database per project and includes 1 GiB of storage, daily read, write, and delete allowances, and 10 GiB monthly outbound transfer. New customers receive $300 in credits, separate from that quota. Server client libraries bypass Firestore Security Rules, so server access needs IAM controls.
