Webiny is an open-source, self-hosted content platform and headless CMS that runs serverlessly inside the user's AWS account. Its TypeScript framework provides a GraphQL API, custom content models, field-level permissions, localization, versioning, lifecycle hooks, dependency injection, admin UI and infrastructure extension points, and supports AI-assisted development through an MCP server. The platform includes a visual website builder with a Next.js SDK, a file manager for digital assets, publishing workflows with drafts, reviewers, scheduled publishing and audit trails, and native multi-tenancy with isolated data, users, assets and permissions. It runs on AWS Lambda, DynamoDB, S3 and CloudFront, with infrastructure provisioned through Pulumi; optional OpenSearch and VPC configurations are also supported. Webiny is extended through code and can be deployed using open-source infrastructure templates rather than managed servers.

Syncular is an offline-first SQL synchronization toolkit that keeps an SQLite database on each client while treating a server-owned commit log as authoritative. Applications read and write local SQLite immediately; writes enter an outbox and are checked and reconciled by the server during synchronization. The browser client runs SQLite on OPFS, while native integrations share a Rust core with native SQLite through bindings for Rust, Swift, Kotlin, Flutter, React Native, and Tauri. Servers can run on Bun, Node, or Cloudflare Workers with SQLite, Postgres, or D1. The project also provides server-side persistent SyncClients, database-less SyncRemoteClients, schema and query code generation, React hooks, column encryption, Yjs CRDT integration, and TypeScript and Rust implementations checked against a shared conformance catalog. Syncular is maintained by Benjamin Kniffler and is pre-1.0; its public APIs and protocol details may change before 1.0. The repository is released under the license stated in its repository files.

Obsidian Sync is a subscription service from Obsidian that synchronizes Obsidian vaults across supported devices through the cloud. It supports encrypted synchronization and features such as version history and selective vault settings.
