Browser, Node.js, Edge. One API. Zero compromises.
NebulaDB v0.6.0 "Cumulus" brings first-class cloud and edge support — Cloudflare D1, Deno KV, Vercel KV, AWS Lambda, and hybrid deployment. 40+ packages, 15+ adapters, TypeScript-first, reactive, and MIT-licensed.
From browser to server to edge — one consistent, reactive, TypeScript-first API.
First-class support for Cloudflare D1, Deno KV, Vercel KV, and AWS Lambda. Deploy anywhere with zero configuration changes.
Combine local and remote storage — SQLite locally, Cloudflare D1 in production. Automatic sync with conflict resolution.
Live subscriptions push updates to your UI when data changes. Subscribe to any query and get real-time results.
Transparent encryption at rest with field-level control. PBKDF2 key derivation. HIPAA/PCI/GDPR ready.
Swap storage backends without changing code. Memory, IndexedDB, SQLite, PostgreSQL, MongoDB, Redis, and more.
Extend with plugins: encryption, sync, audit, backup, streaming, geospatial, auth, and more. Compose functionality.
B-tree, hash, geospatial, and full-text indexes. Automatic index selection and query optimization.
Runs natively in browsers with full crypto support. IndexedDB, LocalStorage, and Memory adapters included.
Choose the right storage for every environment — all with the same NebulaDB interface.
Same API across all environments. No lock-in. No vendor-specific code.
NebulaDB adapters abstract away the storage layer so your database code stays the same whether you're running in the browser, on Node.js, or at the edge.
