Dyad is a local-first, open-source AI coding assistant that helps you build and iterate on web apps from your own machine. You can chat with Dyad to scaffold code, review changes, or debug issues all inside your editor. Unlike most cloud-based tools, Dyad runs locally, supports any LLM (including GPT, Claude, and Gemini), and even lets you plug in open weights via Ollama.

Just Launched: Dyad’s Portal Template, Backed by Neon

In its latest release (v0.16.0-beta.1), Dyad introduced a new Portal template – a full-stack app scaffold that ships with role-based permissions, a real database schema, and built-in undo support for database changes.

At the core of it is Postgres, powered by Neon. With Neon’s serverless Postgres as the backend, AI-generated apps in Dyad now support persistent state without the user needing to set up any infrastructure. The Portal template is already live in Dyad’s UI – you can spin up a working app, with Neon Postgres under the hood, and start coding against it immediately. 

Using Neon Branches for Undo and Checkpoints

One of the most powerful things Dyad gains from Neon is the ability to offer a database undo feature, letting users rewind time and restore earlier states of their app, including the database.

Behind the scenes, Dyad uses Neon’s branching and Instant Restore APIs to implement this workflow. When a user creates or edits an app, Dyad writes those changes to a development branch (a child of the production branch). If something goes wrong, the user can roll back to an earlier point in time.

This architecture allows Dyad to support:

  • Previewing older states (like git commits for your app + DB)
  • Restoring earlier app versions, including the database schema and content
  • Safe experimentation, with branching used as a form of checkpointing

Neon and agents

Neon is a serverless Postgres platform designed for modern development and agentic workflows. It powers backends for agents with an unparalleled developer experience: instant provisioning, seamless no-signup flows, and branching for checkpoints and versioning. Agentic platforms like Replit Agent, Databutton, Create.xyz, and many others use Neon under the hood.
