webiny-js

webiny-js is a local-AI tool - Open-source, self-hosted CMS platform on AWS serverless (Lambda, DynamoDB, S3). TypeScript framework with multi-tenancy, lifecycle hooks, GraphQL API, and AI-assisted development via MCP server. Built for developers at large organizations.

Overview

Open-source content platform. Self-hosted on AWS serverless. Built as a TypeScript framework you extend with code, not a closed product you configure through a UI.

Runs on Lambda, DynamoDB, S3, and CloudFront inside your own AWS account. Scales automatically. No servers to manage. Infrastructure provisioned via IaC (Pulumi) in a single 'deploy' command.

Used in production by teams managing hundreds of millions of content records, petabytes of assets, and thousands of editors — including Amazon, Emirates, Fortune 500 companies, government agencies, and SaaS platforms that white-label Webiny inside their own products.

Headless CMS — Custom content models, GraphQL API, field-level permissions, localization, versioning. Models can be defined through the admin UI or in code via the framework.

Website Builder — Visual drag-and-drop page editor with a Next.js SDK. Render pages through your own frontend (Vercel, CloudFront, wherever). Create custom page elements with React components.

File Manager — Digital asset management with CDN delivery, folder structure, tagging, search. Integrated into CMS and Website Builder.

Publishing Workflows — Multi-step content approval with draft states, reviewer assignments, scheduled publishing, and audit trails.

webiny-js is open-source, written primarily in TypeScript, with 7,990 GitHub stars under the Other license. The latest release is v6.4.1 (2026-06-02).

How it fits a local-AI stack

webiny-js runs on your own hardware, so pair it with a model and a GPU sized to your needs. Use the VRAM calculator to pick a model that fits your card, and see what you can run for hardware guidance. Related local-AI tools in the directory:
